Collagen is a protein composed of three associated alpha polypeptide chains. Each is made up of a sequence of 1,055 amino acids. The most common are :<\/p>\n\n      <ul style=\"margin: 20px 0 30px; padding-left: 24px; line-height: 1.9;\">\n        <li><strong>proline<\/strong><\/li>\n        <li><strong>lysine<\/strong><\/li>\n        <li><strong>wisteria<\/strong><\/li>\n        <li><strong>hydroxylysine<\/strong><\/li>\n        <li><strong>hydroxyproline<\/strong><\/li>\n      <\/ul>\n\n      <h3 style=\"font-family: var(--bd-serif); font-size: 22px; font-weight: 500; margin: 40px 0 20px;\">Collagen's role in skin and joints<\/h3>\n\n      <p>There are many types of collagen in the human body. The most widely studied for supplementation are <strong>type 1<\/strong>, present almost everywhere, and the <strong>type 2<\/strong>, collagen is found mainly in cartilage. In the skin, collagen maintains skin elasticity and firmness.<\/p>\n\n      <p>But from the age of 25 onwards, collagen production gradually declines, and <strong>from the age of 40, we lose around 1 % of collagen per year<\/strong>. The result: loss of elasticity, sagging skin and the appearance of wrinkles. The dermis becomes thinner and loses its ability to retain moisture. Added to this is the environment, which further degrades collagen: UV rays, pollution, smoking.<\/p>\n    <\/div>\n  <\/section>\n\n  <!-- ============ INSTAGRAM EMBED ============ -->\n  <section class=\"bd-section\">\n    <div class=\"bd-wrap\" style=\"display: flex; justify-content: center;\">\n      <blockquote class=\"instagram-media\" data-instgrm-captioned data-instgrm-permalink=\"https:\/\/www.instagram.com\/reel\/Ctleb8qIUoZ\/?utm_source=ig_embed&#038;utm_campaign=loading\" data-instgrm-version=\"14\" style=\"background:#FFF; border:0; border-radius:16px; box-shadow:0 20px 50px rgba(42,36,56,0.12); margin: 1px; max-width:540px; min-width:326px; padding:0; width:99.375%;\"><div style=\"padding:16px;\"> <a href=\"https:\/\/www.instagram.com\/reel\/Ctleb8qIUoZ\/?utm_source=ig_embed&#038;utm_campaign=loading\" target=\"_blank\" rel=\"noopener\">See this post on Instagram<\/a><\/div><\/blockquote>\n      <script async src=\"\/\/www.instagram.com\/embed.js\"><\/script>\n    <\/div>\n  <\/section>\n\n  <!-- ============ SECTION III \u2014 ALIMENTATION ============ -->\n  <section class=\"bd-section\">\n    <div class=\"bd-wrap\">\n      <div class=\"bd-section-divider\">\n        <span class=\"bd-section-num\">III<\/span>\n        <span class=\"bd-section-line\"><\/span>\n      <\/div>\n      <h2>A collagen-rich diet <em>- what really goes<\/em>.<\/h2>\n      <p class=\"bd-lead\">Facial care and a healthy lifestyle slow the breakdown of collagen, but our current diet is rather lacking in it - hence the craze for supplementation.<\/p>\n\n      <p>Collagen can be found in marrow bone, bone broth or fish skin.

This synergy corresponds precisely to the fifth criterion detailed above: <em>the best supplements combine peptides, vitamin C, zinc and sulfur to boost collagen bioavailability<\/em>.
