There are at least 28 distinct types of collagen, with types I, II, and III being the most abundant. Type I collagen (the most common of all) dominates skin, bone, tendons, and ligaments; type II is specific to articular cartilage; type III coexists with type I in skin and blood vessels. Collagen synthesis is performed by fibroblasts (skin, tendons, ligaments), chondrocytes (cartilage), and osteoblasts (bone), in a process that requires several nutritional cofactors (vitamin C, zinc, copper, specific amino acids). From the age of 25, collagen synthesis progressively declines (~1.5% per year), with progressive consequences for skin elasticity, joint integrity, tendon strength, and bone density.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePeptan®: the reference quality standard for collagen peptides:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePeptan®\u003c\/strong\u003e is the registered trademark for collagen peptides from Rousselot (part of the Darling Ingredients group), the world's largest gelatin and collagen peptide company, with certified factories on multiple continents. Peptan® is available in fish version (Peptan F, derived from fish skin) and bovine version (Peptan B). Peptan F (fish) has an average molecular weight of peptides of ~2000 Da (vs. ~3000 Da for conventional bovine collagen), resulting in faster and more efficient intestinal absorption. Peptan® certification guarantees: a controlled enzymatic hydrolysis process that produces bioactive peptides of optimal size for absorption; protein purity greater than 97% (dry basis); absence of contaminants; and full traceability of the production chain. The scientific evidence associated with Peptan® includes more than 30 clinical trials published in peer-reviewed journals on the effects of Peptan® on joint, skin, and bone health parameters.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCollagen hydrolysis and bioactive peptides: why hydrolyzed collagen is superior to unhydrolyzed collagen:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eNative (unhydrolyzed) collagen is a high molecular weight protein (~300 kDa) that would be digested by gastrointestinal proteases into individual amino acids before absorption, losing its biological specificity. \u003cstrong\u003eHydrolyzed collagen\u003c\/strong\u003e is enzymatically pre-digested into \u003cstrong\u003elow molecular weight peptides\u003c\/strong\u003e (2000 to 5000 Da) that are absorbed intact into enterocytes and reach circulation as dipeptides and tripeptides with specific sequences (especially Pro-Hyp and Hyp-Gly, rich in hydroxyproline) that have direct biological activity: they stimulate collagen synthesis by fibroblasts and chondrocytes by acting as signals that \"inform\" these cells that tissue collagen is being degraded and needs to be replaced. This physiological feedback mechanism is the biochemical basis for the clinical efficacy of hydrolyzed collagen peptides. Tracking studies with radioactively labeled collagen (Shaw et al., 2017; Oesser et al., 1999) confirmed that hydrolyzed collagen peptides are absorbed intact and accumulate in collagen-rich tissues (skin, cartilage, tendons) with peak concentration at 12 hours.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eJoint health and cartilage: the sports application with the strongest evidence base:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe application with the most solid clinical evidence for collagen peptides is support for joint health and cartilage integrity in athletes and people with osteoarthritis. The study by Shaw et al. (2017), published in the American Journal of Clinical Nutrition, documented that supplementation with 15g of hydrolyzed collagen + vitamin C 1 hour before specific joint exercise increased collagen content in engineered ligament tissue by 2x compared to placebo, with a peak of bioactive collagen peptides in circulation coinciding with the post-exercise collagen synthesis window. The meta-analysis by Zdzieblik et al. (2021) with data from trials in athletes documented that collagen peptide supplementation significantly reduced joint pain at rest and during exercise, especially in knees and ankles subjected to repeated impact. For athletes who practice sports with high joint load (running, weightlifting, team sports), collagen peptides are one of the supplements with the best evidence\/cost ratio for preventing tendon and ligament injuries.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSkin health: wrinkle reduction, improved elasticity and hydration:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSkin is composed of ~75% collagen (mainly type I and III) and is one of the tissues most affected by the decline in collagen synthesis associated with aging and UV exposure. The randomized clinical trial by Proksch et al. (2014), published in Skin Pharmacology and Physiology with 69 women over 8 weeks, documented that 2.5g\/day of Peptan® collagen peptides significantly improved skin elasticity, hydration, and roughness compared to placebo. Collagen peptides accumulate in the skin and stimulate dermal fibroblasts to produce more type I and III collagen, elastin, and hyaluronic acid, improving the structure and hydration of the dermal extracellular matrix.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMuscle recovery and body composition:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCollagen peptides are rich in the amino acids glycine, proline, and hydroxyproline (which together represent ~50% of collagen's amino acid composition), with lower content of essential branched-chain amino acids (BCAAs) compared to whey. In this sense, hydrolyzed collagen complements (but does not replace) high-quality complete proteins (whey, casein) in the context of post-workout protein nutrition. The trial by Zdzieblik et al. (2015) documented that supplementation with 15g of hydrolyzed collagen in conjunction with progressive resistance training increased lean muscle mass and reduced body fat in sarcopenic elderly subjects compared to placebo, suggesting that the glycine and proline in collagen may support the synthesis of muscular connective tissue (fascia and epimysium) in addition to articular collagen synthesis.\u003c\/p\u003e\n\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eUses\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eRecommended dose:\u003c\/strong\u003e Dissolve 11g (1 scoop) in water, milk, juice, or add to any drink or food at breakfast. To optimize effects on joint health (based on the protocol by Shaw et al., 2017), take 15 to 30 minutes before specific joint exercise (running, weight training, jumping), preferably with a source of vitamin C (which is an obligatory cofactor for the enzymes prolyl-4-hydroxylase and lysyl-hydroxylase, essential for collagen fiber maturation). The benefits are cumulative and require regular use for at least 8 to 12 weeks.\u003c\/p\u003e","brand":"Marvelous Nutrition","offers":[{"title":"Default Title","offer_id":52705353662811,"sku":null,"price":29.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1005\/0250\/3771\/files\/MarvelousNutrition-COLLAGEN.webp?v=1776792370","url":"https:\/\/brothers-club.com\/en\/products\/product_363b16a1-50c4-4169-8192-9d0bb984c356","provider":"Brother's Club","version":"1.0","type":"link"}
