It is not a trendy ingredient. It is literally what keeps your body in one piece.  <\/p>\n\n<p class=\"wp-block-paragraph\">To give you an idea of just how important it is: collagen accounts for around 30% of all the body\u2019s proteins. It is found in the skin, bones, tendons, ligaments, blood vessels and many internal organs. Without it, tissues would gradually lose their ability to withstand the stresses of everyday life.  <\/p>\n\n<p class=\"wp-block-paragraph\">What few people realise is that its production starts to decline from the age of 25 \u2013 not 50, not 40: 25. And this decline, estimated at around 1% per year, continues silently and steadily for decades. <\/p>\n\n<p class=\"wp-block-paragraph\">Faced with this observation, thousands of people are asking themselves the same questions: Is a dietary supplement based on collagen really effective? Should you choose marine or bovine? What dose? What does science actually say? The aim of this guide is to answer these questions with rigour, without hype or oversimplification.    <\/p>\n\n<p class=\"wp-block-paragraph\">At Sashinah, we believe that informed decisions are based on reliable information. That is why this article draws on the latest scientific evidence whilst remaining accessible to everyone. <\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>The<\/strong> <strong>essentials of collagen<\/strong><strong><\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Key figures for collagen<\/p>\n\n<p class=\"wp-block-paragraph\">To better understand the importance of collagen in the body, here are a few key points to bear in mind:<\/p>\n\n<figure class=\"wp-block-table is-style-regular\"><table class=\"has-fixed-layout\" style=\"border-width:0.1px\"><thead><tr><td><strong>Indicator<\/strong><\/td><td><strong>Value<\/strong><\/td><\/tr><\/thead><tbody><tr><td>The proportion of the body\u2019s protein mass accounted for by collagen<\/td><td>Around 30%<\/td><\/tr><tr><td>Number of collagen types identified<\/td><td>More than 28<\/td><\/tr><tr><td>The most common type<\/td><td>Type I<\/td><\/tr><tr><td>Proportion of type I collagen in total collagen<\/td><td>Around 90%<\/td><\/tr><tr><td>The start of the natural decline<\/td><td>Around the age of 25<\/td><\/tr><tr><td>Estimated annual loss<\/td><td>Around 1%<\/td><\/tr><tr><td>Duration typically studied in clinical trials<\/td><td>8 to 12 weeks<\/td><\/tr><tr><td>An essential cofactor for its synthesis<\/td><td>Vitamin C<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<h3 class=\"wp-block-heading has-small-font-size\">These data help us to better understand why the collagen arouses so much interest in the fields of the skin, the joints and the connective tissues.<\/h3>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Contents<\/strong><\/h3>\n\n<ul class=\"wp-block-list\">\n<li id=\"partie-1\"><a href=\"#partie-1\" data-type=\"internal\" data-id=\"#partie-1\"><strong>Part 1 \u2013 Everything you need to know about collagen<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"#partie-2\"><strong>Part 2 \u2013 The different types of collagen<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"#partie-3\" data-type=\"internal\" data-id=\"#partie-3\"><strong>Part 3 \u2013 The benefits for the skin<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"#partie-4\" data-type=\"internal\" data-id=\"#partie-4\"><strong>Part 4 \u2013 Joints, bones and sport<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"#partie-5\" data-type=\"internal\" data-id=\"#partie-5\"><strong>Part 5 \u2013 How to choose a high-quality collagen<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"#partie-6\" data-type=\"internal\" data-id=\"#partie-6\"><strong>Part 6 \u2013 Answers to key questions about collagen<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"#produit-sashinah\" data-type=\"internal\" data-id=\"#produit-sashinah\"><strong>Which Sashinah product should I choose?<\/strong><\/a><\/li>\n\n\n\n<li><a href=\"#conclusion\" data-type=\"internal\" data-id=\"#conclusion\"><strong>Conclusion<\/strong><\/a><\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Part 1 \u2013 Everything you need to know about the protein most abundant in the human body<\/strong><\/h3>\n\n<h4 class=\"wp-block-heading has-medium-font-size\"><strong>What is collagen?<\/strong><\/h4>\n\n<p class=\"wp-block-paragraph\">Collagen is the most abundant structural protein in the human body. It alone, it accounts for approximately 30% of all the proteins present in the body. Its main role is to ensure the cohesion, strength, flexibility and elasticity of tissues.  <\/p>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Tissue<\/strong><\/td><td><strong>Presence of collagen<\/strong><\/td><\/tr><tr><td>Skin<\/td><td>Very high<\/td><\/tr><tr><td>Sinew<\/td><td>Very high<\/td><\/tr><tr><td>Ligaments<\/td><td>Very high<\/td><\/tr><tr><td>Bone<\/td><td>Very high<\/td><\/tr><tr><td>Cartilage<\/td><td>High<\/td><\/tr><tr><td>Blood vessels blood vessels<\/td><td>Moderate<\/td><\/tr><tr><td>Muscles<\/td><td>Moderate<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>The origin of the word \u2018collagen\u2019<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">The term \u2018collagen\u2019 derives from Ancient Greek *kolla*, which means \u2018glue\u2019. This etymology is particularly revealing: collagen acts as a biological cement capable of maintaining a18&gt; biological cement capable of holding together the various structures of the body. <\/p>\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/structure_moleculaire_collagene_1200x800-1024x683.webp\" alt=\"The molecular structure of collagen as a triple helix illustrating the architecture of the fibres of collagen in the human body\" class=\"wp-image-9374\" style=\"aspect-ratio:16\/9;object-fit:contain;width:850px\" srcset=\"https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/structure_moleculaire_collagene_1200x800-1024x683.webp 1024w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/structure_moleculaire_collagene_1200x800-300x200.webp 300w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/structure_moleculaire_collagene_1200x800-768x512.webp 768w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/structure_moleculaire_collagene_1200x800-600x400.webp 600w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/structure_moleculaire_collagene_1200x800.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>An exceptional molecular structure<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">What makes collagen unique is its triple-helix structure. Three protein chains wind around each other to form an extremely strong fibre. At a microscopic level, it can be compared to a braided cable made up of several intertwined strands. This structure enables it to withstand significant mechanical stress whilst retaining a degree of flexibility.   <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>The amino acids that make up collagen<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Like all proteins, collagen is made up of amino acids. Three of these play a key role: <\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Glycine accounts for approximately one third of the composition. Its small size is essential for the formation of the triple helix. <\/strong><\/li>\n\n\n\n<li><strong>Proline contributes to the stability and mechanical strength of fibres.<\/strong><\/li>\n\n\n\n<li><strong>Hydroxyproline, which is particularly characteristic of collagen, plays a key role in the stability of the triple helix and is used as a marker in many scientific studies.<\/strong><\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Why is collagen so important?<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Its role extends far beyond the realm of beauty. In the skin, it is one of the main components of the dermis and contributes to the skin\u2019s firmness, elasticity and resilience. In bones, it accounts for around 90% of the organic matrix and acts as a framework to which minerals attach. In joints, it helps with shock absorption and contributes to the structure of cartilage. In tendons and ligaments, it gives them their exceptional strength.    <\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>At what age do we start to lose collagen?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">One of the most common misconceptions is that collagen loss only begins after the age of 50. In reality, research shows that natural collagen production starts to decline from around the age of 25, at a rate estimated at around 1% per year. The effects become progressively more noticeable over time.  <\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Why does the production of collagen decrease with age?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">The decline in collagen is not solely linked to chronological ageing. Several biological mechanisms gradually combine over the years. <\/p>\n\n<p class=\"wp-block-paragraph\">As we get older, fibroblasts \u2013 the cells responsible for producing collagen \u2013 become less active. Natural collagen production then gradually slows down. <\/p>\n\n<p class=\"wp-block-paragraph\">At the same time, oxidative stress caused by UV rays, pollution, smoking or certain lifestyle habits contributes to the breakdown of existing fibres.<\/p>\n\n<p class=\"wp-block-paragraph\">Les changements hormonaux jouent \u00e9galement un r\u00f4le important. Chez les femmes, la baisse des \u0153strog\u00e8nes observ\u00e9e lors de la m\u00e9nopause est notamment associ\u00e9e \u00e0 une acc\u00e9l\u00e9ration de la perte de collag\u00e8ne cutan\u00e9. <\/p>\n\n<p class=\"wp-block-paragraph\">Finally, glycation\u2014a process exacerbated by a chronic excess of sugar\u2014gradually stiffens collagen fibres and reduces their effectiveness.<\/p>\n\n<p class=\"wp-block-paragraph\">All of these factors explain why the quality and quantity of collagen gradually decline over the years.<\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Factors that accelerate collagen loss<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\"><strong>What you need to remember<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Collagen is the most abundant structural protein in the human body.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Il repr\u00e9sente environ 30 % de l\u2019ensemble des prot\u00e9ines de l\u2019organisme.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 More than 28 types of collagen have been identified to date.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Types I, II and III are the most common and most widely studied forms in the fields of skin, bone and joints.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Its triple-helix structure gives it remarkable strength.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Natural production begins to decline gradually from the age of 25.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 A number of everyday factors can speed up its deterioration.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Its role extends far beyond the realm of beauty and affects many tissues in the body.<\/p>\n\n<h1 class=\"wp-block-heading has-medium-font-size\" id=\"partie-2\"><strong>Part 2 \u2013 The different types of collagen: which one should you choose depending on your goal?<\/strong><\/h1>\n\n<p class=\"wp-block-paragraph\">To date, researchers have identified more than 28 different types of collagen in the human body. However, not all of them are of equal interest to the general public or in the field of dietary supplements. <\/p>\n\n<p class=\"wp-block-paragraph\">Types I, II and III account for the vast majority of collagen in the body and are the most widely studied in relation to the skin, joints, bones and connective tissues. Types V and X are also attracting growing interest due to their presence in certain specialised tissues. <\/p>\n\n<p class=\"wp-block-paragraph\">The other types of collagen (IV, VI, VII, VIII, IX, XI, XII, XIII and subsequent types) play essential roles in various structures of the body, including cell membranes, blood vessels, muscles, kidneys, eyes and certain specialised tissues.<\/p>\n\n<p class=\"wp-block-paragraph\">In addition to the various types of collagen, it is also important to distinguish the main sources used in the dietary supplements.<\/p>\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"603\" src=\"https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/femmes_collagene-1024x603.webp\" alt=\"Three women of different ages illustrating the natural changes in collagen over time\" class=\"wp-image-9377\" srcset=\"https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/femmes_collagene-1024x603.webp 1024w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/femmes_collagene-300x177.webp 300w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/femmes_collagene-768x453.webp 768w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/femmes_collagene-1536x905.webp 1536w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/femmes_collagene-1320x778.webp 1320w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/femmes_collagene-600x354.webp 600w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/femmes_collagene.webp 1634w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\" style=\"border-width:0.1px\"><thead><tr><td><strong>Source<\/strong><\/td><td><strong>Types principalement pr\u00e9sents<\/strong><\/td><td><strong>Special features<\/strong><\/td><\/tr><\/thead><tbody><tr><td>Marin<\/td><td>Type I<\/td><td>Widely used in beauty and wellness products for the skin<\/td><\/tr><tr><td>Cattle<\/td><td>Types I and III<\/td><td>A versatile approach to skin, bone and connective tissue<\/td><\/tr><tr><td>Pig<\/td><td>Types I and III<\/td><td>Profile similar to bovine collagen<\/td><\/tr><tr><td>Poultry<\/td><td>Mainly type II<\/td><td>Often used in joint supplements<\/td><\/tr><tr><td>Eggshell membrane (ESM\u00ae)<\/td><td>Types I, V and X<\/td><td>Contient naturellement de l&#8217;acide hyaluronique, de la glucosamine et de la chondro\u00eftine<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\">It is therefore important not to confuse the different types of collagen (I, II, III, V, X, etc.) with the sources of collagen (marine, bovine, porcine, poultry or eggshell membrane).

The epidermis is the visible outer layer, acting as a barrier against external aggressions. The dermis lies just beneath it: this is where most of the skin\u2019s collagen is found, along with elastin fibres, hyaluronic acid and fibroblasts. The hypodermis, the deepest layer, mainly contains fat cells and supporting tissue.   <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Fibroblasts: the skin\u2019s collagen-producing cells<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Fibroblasts are cells specialised in producing collagen, elastin and certain components of the dermis. When we are young, their activity is particularly high. As we age, their effectiveness gradually declines, which explains the natural decline in the skin\u2019s collagen production.  <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>How do collagen peptides affect the skin?<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">For a long time, scientists believed that ingested collagen was simply digested like any other dietary protein. Recent research has refined this understanding. After ingestion, hydrolysed collagen is broken down into specific peptides which are absorbed in the gut, enter the bloodstream and can reach the skin tissue. These peptides act as biological signals to fibroblasts, stimulating the synthesis of new collagen and hyaluronic acid. This biostimulation mechanism is now one of the most active areas of research in this field.    <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>This is what scientific studies show<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">The most rigorous studies are double-blind, randomised clinical trials, often conducted over periods of 8 to 12 weeks. The main findings observed are as follows: <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Elasticity of the skin<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Elasticity refers to the skin\u2019s ability to return to its original shape after being stretched. It is the most widely studied criterion and the one for which the evidence is strongest. The study by Proksch et al. (2014), published in Skin Pharmacology and Physiology, observed a significant improvement in skin elasticity compared to the placebo group after 8 weeks of supplementation with specific collagen peptides.  <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Skin hydration<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Hydration plays an important role in skin comfort and overall skin appearance. Studies consistently show an improvement in hydration following prolonged supplementation, with noticeable results from 6 to 8 weeks onwards. This effect is partly explained by the stimulation of hyaluronic acid production in the dermis.  <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Skin density<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Some studies using ultrasound have observed positive positive changes in certain markers associated with dermal density. These results suggest a a16&gt; possible increase in the concentration of fibres of collagen in the dermis, although the exact mechanisms remain to be clarified. <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Wrinkles and visible signs of ageing<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">The results regarding the visible reduction of wrinkles vary across studies. The level of evidence is classified as moderate. The improvements observed are generally subtle and gradual rather than dramatic, which highlights the importance of having realistic expectations.  <\/p>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Field studied<\/strong><\/td><td><strong>Level of exam<\/strong><\/td><\/tr><tr><td>Elasticity of the skin<\/td><td>Pupil<\/td><\/tr><tr><td>Hydration<\/td><td>Pupil<\/td><\/tr><tr><td>Skin density<\/td><td>Moderate to high<\/td><\/tr><tr><td>Texture of the skin<\/td><td>Moderate<\/td><\/tr><tr><td>General appearance<\/td><td>Moderate<\/td><\/tr><tr><td>Reduction in wrinkles<\/td><td>Moderate<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>The enemies of skin collagen<\/strong><\/h3>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>UV rays<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">UV rays are likely the main external factor contributing to collagen breakdown. They promote oxidative stress, inflammation and the activation of enzymes known as matrix metalloproteinases (MMPs), which actively break down collagen fibres. This phenomenon, known as photoageing, can significantly accelerate the loss of skin density.  <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Tobacco<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Smoking reduces tissue oxygenation and increases oxidative stress, two mechanisms that directly accelerate collagen breakdown.<\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Excess sugar<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">A chronic excess of sugar promotes a process known as glycation. Glucose molecules bind to collagen fibres, gradually making them stiffer and less functional. This process, known as the formation of advanced glycation end products (AGEs), contributes to premature skin ageing.  <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>lack of sleep<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Sleep is one of the most important periods for the body\u2019s natural tissue repair processes. Insufficient or poor-quality sleep disrupts fibroblast regeneration. <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Which nutrients should be combined with collagen for the skin?<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Collagen never works alone. Several cofactors are essential for its normal synthesis: <\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Vitamin C \u2014 an essential cofactor. It plays a direct role in the hydroxylation of proline and lysine, key steps in the formation of the triple helix.

Walking, climbing stairs, running and standing up from a chair place constant strain on the joints, bones, tendons, ligaments and muscles. Collagen is present in each of these tissues and acts as an essential structural component.  <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Cartilage: a tissue rich in collagen<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Joint cartilage is mainly composed of water, type II collagen, proteoglycans and specialised cells known as chondrocytes. It plays a vital role: absorbing shocks, distributing mechanical stress and enabling smooth movement. Without this structure, every movement would cause significant friction between the bones.  <\/p>\n\n<p class=\"wp-block-paragraph\">Cartilage has an important biological characteristic: it is avascular, meaning it contains no blood vessels. Its regeneration is therefore much slower than that of other tissues, which explains why the effects of supplementation generally take several weeks to several months to become noticeable. <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>This is what the scientific studies say<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">The study by Bello &amp; Oesser (2006) in Clinical Interventions in Aging, focusing on hydrolysed collagen and joint tissues, is one of the references that are most frequently cited in this field. Generally speaking, researchers are interested in several criteria: joint comfort, mobility, flexibility of movements and recovery after exercise. The results the most interesting are generally observed after several weeks or several months of regular use.  <\/p>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Field studied<\/strong><\/td><td><strong>Level of exam<\/strong><\/td><\/tr><tr><td>Joint mobility<\/td><td>Moderate<\/td><\/tr><tr><td>Comfort for the joints<\/td><td>Moderate to high<\/td><\/tr><tr><td>Athletes<\/td><td>Moderate<\/td><\/tr><tr><td>Cartilage quality<\/td><td>Promising<\/td><\/tr><tr><td>Flexibility of movement<\/td><td>Moderate<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Collagen and the bones<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Contrary to popular belief, bones are not made up solely of calcium. Type I collagen accounts for around 90% of their organic matrix and acts as a scaffold to which minerals attach. Without this structure, bones would be much more fragile and would shatter like glass. The study by K\u00f6nig et al. (2018), published in Nutrients, observed positive effects of specific collagen peptides on bone mineral density in postmenopausal women, suggesting potential benefits in a holistic approach to bone health.   <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Collagen and exercise<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Athletes are interested in collagen for one simple reason: whilst muscles adapt relatively quickly to training, tendons and ligaments\u2014which are rich in collagen\u2014take much longer to do so. This discrepancy explains why tendon injuries are common among athletes who progress too quickly. <\/p>\n\n<p class=\"wp-block-paragraph\">The study by Shaw et al. (2017), published in the American Journal of Clinical Nutrition, showed that supplementation with vitamin C-enriched gelatine, taken approximately one hour before exercise, significantly increased collagen synthesis in tendons. This finding has reinforced the value of protocols combining collagen and vitamin C in the context of sports recovery. <\/p>\n\n<p class=\"wp-block-paragraph\">The most widely studied protocols generally involve taking 10 to 15 g of hydrolysed collagen combined with vitamin C, consumed regularly over several weeks.<\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Which Sashinah formula is best for the joints? Collagen Flexura\u00ae <\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Collagen Flexura\u00ae has been developed for people looking for a formula designed to support mobility and joint comfort. Its formulation combines Peptan\u00ae B, glucosamine, MSM, chondroitin, vitamin C, vitamin D3, vitamin E and B vitamins. <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Which package does Sashinah offer for a comprehensive approach?

The complete buying guide <\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">The collagen market has been growing spectacularly for several years. For consumers, this abundance of products is often a source of confusion. How can you tell a genuine product from mere marketing hype?  <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Why are not all the collagens all the same?<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">The differences between products may relate to the source, the type of collagen, the manufacturing process, the quality of raw materials, the dosage, the ingredients used and traceability. The price alone does not allow us to judge the quality of a product. <\/p>\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/poudre_collagene_cuilleres_1200x800-1024x683.webp\" alt=\"\" class=\"wp-image-9373\" srcset=\"https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/poudre_collagene_cuilleres_1200x800-1024x683.webp 1024w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/poudre_collagene_cuilleres_1200x800-300x200.webp 300w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/poudre_collagene_cuilleres_1200x800-768x512.webp 768w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/poudre_collagene_cuilleres_1200x800-600x400.webp 600w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/poudre_collagene_cuilleres_1200x800.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Criterion 1: the source of collagen<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">The source is one of the most important criteria. The choice between marine, bovine, bovine cartilage or eggshell membrane depends primarily on the intended purpose (see table in section 2). <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Criterion 2: hydrolysed or non-hydrolysed?<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Hydrolysed collagen is broken down into smaller peptides, making it easier to dissolve and absorb. It is currently the most widely available form on the market and the one that has been most extensively studied scientifically. Undenatured collagen retains its native structure and is mainly studied in certain specific joint applications with different mechanisms of action.  <\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Criterion 3: the molecular weight<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">The molecular weight corresponds to the average size of collagen peptides following hydrolysis. It is expressed in daltons (Da). Generally speaking, the smaller the peptides, the easier they are to dissolve and for the body to absorb.  <\/p>\n\n<p class=\"wp-block-paragraph\">However, the molecular weight does not in itself the sole indicator of quality. The source of collagen, the manufacturing process, the traceability of raw materials, the dosage and the level of scientific documentation are also criteria that are essential to take into account. <\/p>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Molecular weight<\/strong><\/td><td><strong>General specifications<\/strong><\/td><\/tr><tr><td>&gt; 5000 Da<\/td><td>Larger peptides<\/td><\/tr><tr><td>2,000 to 5,000 Da<\/td><td>Medium size, commonly used in food supplements<\/td><\/tr><tr><td>&lt; 2000 Da<\/td><td>Small peptides, valued for their excellent solubility<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\">Modern hydrolysed collagens generally use peptides with a molecular weight of between 2,000 and 5,000 Da. Certain premium raw materials, such as the Peptan\u00ae collagen peptides used in several Sashinah formulations, have a molecular weight of 2,000 Da and are backed by extensive scientific evidence. <\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Key takeaways<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>A lower molecular weight generally promotes the dissolution of collagen.<\/li>\n\n\n\n<li>Molecular weight alone is not a reliable indicator of a product\u2019s quality.<\/li>\n\n\n\n<li>Overall quality also depends on the source, traceability, dosage and the available scientific studies.<\/li>\n\n\n\n<li>Hydrolysed collagens with a molecular weight of around 2,000 Da are among the most commonly used ingredients in modern formulations.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Criterion 4: traceability<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">A reputable brand should be able to specify the source of the collagen, the manufacturer, the supply chain and the quality controls carried out. Transparency is often one of the best indicators of trust. <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Criterion 5: scientific studies<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Not all raw materials are backed by the same level of scientific evidence. Some have been the subject of clinical studies published in peer-reviewed journals. This is particularly true of Peptan\u00ae (Rousselot) and Colartix\u00ae collagens, which are supported by a robust scientific dossier. A well-documented ingredient generally offers greater assurance than an unproven raw material.   <\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Criterion 6: additional ingredients<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Vitamin C is the most important cofactor; its inclusion in the formula is virtually essential. Hyaluronic acid is frequently found in beauty products. Zinc and biotin help maintain healthy skin. Vitamin D is particularly beneficial for joint and bone health.   <\/p>\n\n<p class=\"wp-block-paragraph\">The most comprehensive formulas generally combine several of these ingredients to provide a more holistic approach. Some brands also favour scientifically recognised and documented raw materials, such as Peptan\u00ae, Colartix\u00ae or ESM\u00ae, which are used in many premium formulations. <\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Criterion 7: the transparency of the brand<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Beyond dosage and composition, transparency is a key factor when choosing a dietary supplement. A reputable brand must be able to clearly state the origin of its ingredients, the raw materials used, and provide information that enables consumers to make an informed choice. <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Which dosage should you choose?<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Dosage plays a key role and is often overlooked when choosing a product. Studies on skin health frequently use doses of 2.5 g to 10 g per day. Sports nutrition protocols often use 10 to 15 g per day. Complete formulas generally contain between 5 and 15 g per serving.   <\/p>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Marketing pitfalls to avoid<\/strong><\/h3>\n\n<ul class=\"wp-block-list\">\n<li>Promise immediate results<\/li>\n\n\n\n<li>Promise spectacular changes<\/li>\n\n\n\n<li>Do not specify their source<\/li>\n\n\n\n<li>Hide their actual dosage<\/li>\n\n\n\n<li>Use more marketing than verifiable information<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>Which package Sashinah should I choose?<\/strong><\/h3>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Your main objective<\/strong><\/td><td><strong>Sashinah Package<\/strong><\/td><\/tr><tr><td>Skin beauty<\/td><td>Beauty Glow Essence\u00ae<\/td><\/tr><tr><td>Elasticity and shine<\/td><td>Beauty Glow Essence\u00ae<\/td><\/tr><tr><td>Joint mobility<\/td><td>Flexura\u00ae<\/td><\/tr><tr><td>Sport and recovery<\/td><td>Flexura\u00ae<\/td><\/tr><tr><td>Comprehensive approach<\/td><td>Collagen Synergy\u00ae<\/td><\/tr><tr><td>Skin + joints<\/td><td>Collagen Synergy\u00ae<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><strong>The 7 criteria for premium collagen<\/strong><\/h3>\n\n<ul class=\"wp-block-list\">\n<li>The source.<\/li>\n\n\n\n<li>The type of collagen.<\/li>\n\n\n\n<li>The dosage.<\/li>\n\n\n\n<li>The presence of vitamin C.<\/li>\n\n\n\n<li>Traceability.<\/li>\n\n\n\n<li>Scientific studies.<\/li>\n\n\n\n<li>Brand transparency.<\/li>\n<\/ul>\n\n<p class=\"has-medium-font-size wp-block-paragraph\" id=\"partie-6\"><strong>Part 6 \u2013 Frequently asked questions about collagen<\/strong><\/p>\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/fille_boit_collagene_1200x800-1024x683.webp\" alt=\"A woman drinking a collagen drink as part of her daily wellness routine\" class=\"wp-image-9372\" style=\"aspect-ratio:16\/9;object-fit:contain;width:900px\" srcset=\"https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/fille_boit_collagene_1200x800-1024x683.webp 1024w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/fille_boit_collagene_1200x800-300x200.webp 300w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/fille_boit_collagene_1200x800-768x512.webp 768w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/fille_boit_collagene_1200x800-600x400.webp 600w, https:\/\/sashinah.com\/wp-content\/uploads\/2026\/06\/fille_boit_collagene_1200x800.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Which is the best collagen for the skin?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Type I collagen is currently the most widely studied form of collagen in the field of skin care. Naturally present in the dermis, it plays a key role in the skin\u2019s structure, firmness and elasticity. <\/p>\n\n<p class=\"wp-block-paragraph\">Formulas based on hydrolysed marine collagen, which are rich in type I collagen, are often favoured in beauty-focused dietary supplements.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Which is the best collagen for the joints?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Formulations designed for joint health typically combine different sources of collagen with complementary ingredients such as glucosamine, chondroitin, MSM and eggshell membrane.<\/p>\n\n<p class=\"wp-block-paragraph\">The choice depends primarily on your goals and the overall composition of the formula.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>From what age can you start taking collagen?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">The body&#8217;s natural production of collagen begins to decline gradually from around the age of 25.<\/p>\n\n<p class=\"wp-block-paragraph\">However, most of people start to take an interest in it from the age of 30 to 35, when the first signs associated with ageing become more visible.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Can you take collagen after the age of 50?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Yes. As we get older, the body\u2019s natural production of collagen continues to decline gradually. After the age of 50, this decline often becomes more pronounced, particularly in the skin, bones, joints and connective tissues.  <\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Is collagen beneficial during the menopause?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">The menopause is accompanied by a decline in oestrogen, a hormone involved in various biological processes related to tissue maintenance.<\/p>\n\n<p class=\"wp-block-paragraph\">Some studies show that the loss of collagen in the skin can accelerate during this period. Many women therefore choose to incorporate collagen into a holistic approach comprising diet a18&gt; holistic approach comprising a balanced diet, physical activity on a regular basis and a healthy lifestyle tailored to individual needs. <\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Does collagen make you fat?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">No. Collagen is a protein and does not directly cause weight gain. <\/p>\n\n<p class=\"wp-block-paragraph\">Depending on the product, a daily serving generally provides between 30 and 50 calories, which is a relatively small amount as part of a balanced diet.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>How long does it take to see results?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Scientific studies generally observe the effects after several weeks of regular use.<\/p>\n\n<p class=\"wp-block-paragraph\">For the skin, results are often assessed after 8 to 12 weeks. For joints and connective tissues, the observation periods are sometimes longer. <\/p>\n\n<p class=\"wp-block-paragraph\">Consistency remains a key factor.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Should you take collagen every day?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Yes. Most studies use a daily dose. Taking the supplement regularly helps to replicate the conditions studied in clinical trials.  <\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Should collagen be taken in the morning or in the evening?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">There is no scientific evidence to suggest that any particular time of day is better than another.<\/p>\n\n<p class=\"wp-block-paragraph\">The most important thing is to choose a time that is easy to fit into your routine so that you can ensure a regular intake.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Can you take collagen on an empty stomach?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Yes. Hydrolysed collagen can be taken on an empty stomach, during a meal or after a meal. <\/p>\n\n<p class=\"wp-block-paragraph\">The scientific data currently available do not show any significant difference regarding its absorption depending on the time of consumption.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Can collagen be mixed with coffee or a hot drink?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Yes. Hydrolysed collagen peptides are generally suitable for use in everyday hot drinks such as coffee, tea or certain hot beverages. <\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Why combine collagen and vitamin C?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Vitamin C helps with the normal formation of collagen, which is necessary for a7&gt; functioning of the skin, bones, of cartilage, of blood vessels and of gums.<\/p>\n\n<p class=\"wp-block-paragraph\">That is why it is frequently included in high-quality formulations.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Does plant-based collagen actually exist?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">No. Collagen is a protein that is exclusively of animal origin. <\/p>\n\n<p class=\"wp-block-paragraph\">Products sometimes marketed under the name \u2018plant-based collagen\u2019 do not generally contain collagen, but rather nutrients designed to support its natural synthesis, such as vitamin C or certain amino acids.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Can athletes take collagen?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Yes. Athletes are among the most frequent users of collagen supplements, particularly because of the significant strain placed on their tendons, ligaments, cartilage and connective tissues. <\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Can you take collagen all year round?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Many people opt for regular, long-term use.<\/p>\n\n<p class=\"wp-block-paragraph\">However, it is important to follow the manufacturer\u2019s instructions and seek advice from a healthcare professional in specific circumstances.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Does collagen replace a balanced diet?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">No. No dietary supplement can replace a diet that is varied and balanced, a regular physical activity, a good quality sleep and a healthy lifestyle. <\/p>\n\n<p class=\"wp-block-paragraph\">Collagen forms part of a holistic approach to wellbeing, but is not a substitute for these fundamentals.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Key points to remember<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Collagen is the most abundant structural protein in the human body.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 It accounts for around 30% of the body\u2019s proteins.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 More than 28 types of collagen have been identified to date.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Types I, II and III are the most important for the skin, the joints and the connective tissues.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Natural production begins to decline gradually from the age of 25.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 The areas that are best documented scientifically relate mainly to the elasticity and hydration of the skin.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Bones, joints and supporting tissues are also the subject of extensive research.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 Vitamin C plays an essential role in the normal formation of collagen.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 The quality of a supplement depends just as much on its formulation, as much as its traceability and its dosage as its source.<\/p>\n\n<p class=\"wp-block-paragraph\">\u2713 When choosing a collagen supplement, you should always select one that suits your main goal.<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Who might be interested in collagen?<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Collagen is suitable for all those people wishing to support naturally the development of their body over the course a12&gt; over time, whether it be a matter of preserving the quality of their skin, to support their connective tissues or to maintain good mobility in everyday life.<\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>This may in particular be of interest to:<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li>Adults who are concerned about their overall well-being;<\/li>\n\n\n\n<li>People looking for an approach to beauty from within;<\/li>\n\n\n\n<li>Athletes and physically active people;<\/li>\n\n\n\n<li>People who wish to support their joints and connective tissues;<\/li>\n\n\n\n<li>Women before, during or after the menopause;<\/li>\n\n\n\n<li>People wishing to incorporate some collagen peptides into their daily routine.<\/li>\n<\/ul>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\" id=\"produit-sashinah\"><strong>Our range of collagens includes in particular:<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/sashinah.com\/en\/shop\/supplements\/marine-collagen-beauty-glow-essence\/\" data-type=\"link\" data-id=\"https:\/\/sashinah.com\/boutique\/supplements\/collagene-marin-poudre-beauty-glow-essence\/\"><strong>Collagen marine \u2013 Beauty Glow Essence<\/strong><\/a>, a formula combining hydrolysed marine collagen and beauty active ingredients carefully selected.<br\/><\/li>\n\n\n\n<li><a href=\"https:\/\/sashinah.com\/en\/shop\/supplements\/multi-collagen-synergy\/\" data-type=\"link\" data-id=\"https:\/\/sashinah.com\/boutique\/supplements\/multicollagene-synergy\/\"><strong>Multi-Collagen Synergy<\/strong><\/a>, a complex combining several types of collagen for a holistic approach.<br\/><\/li>\n\n\n\n<li><a href=\"https:\/\/sashinah.com\/en\/shop\/supplements\/marine-collagen-beauty-glow-essence\/\" data-type=\"link\" data-id=\"https:\/\/sashinah.com\/en\/shop\/supplements\/marine-collagen-beauty-glow-essence\/\"><strong>Collagen Flexura<\/strong><\/a>, a formula developed to support those people concerned about their comfort and their mobility in everyday life.<\/li>\n<\/ul>\n\n<p class=\"has-medium-font-size wp-block-paragraph\" id=\"conclusion\"><strong>Conclusion<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Collagen is much more than just a passing fad. It is one of the body\u2019s most important proteins and plays a key role in the structure of many tissues, such as the skin, bones, tendons, ligaments and cartilage. <\/p>\n\n<p class=\"wp-block-paragraph\">Scientific knowledge accumulated over recent decades has led to a better understanding of its role and the mechanisms involved in its natural synthesis. Although no dietary supplement can halt biological ageing, certain lifestyle habits can help to support the long-term maintenance of tissues over time. <\/p>\n\n<p class=\"wp-block-paragraph\">A balanced diet, regular physical activity, a good night\u2019s sleep, appropriate sun protection and consistent a14&gt; supplementation consistent form the foundations of a holistic approach to well-being.<\/p>\n\n<p class=\"wp-block-paragraph\">At Sashinah, our approach is based on a rigorous selection of raw materials, oftransparent formulations and ingredients backed by well-established scientific evidence.
