Hydrolyzed Collagen Studies
Collagen structure
“Hydrolyzed collagen contains 20 amino acids, predominantly glycine, proline and hydroxyproline.”
Study: “What is hydrolyzed collagen?” Rousselot. July 2009.
Collagen assimilation
“More than 90% of hydrolyzed collagen is absorbed within 6 hours of ingestion. An important part is accumulated in cartilage and skin.”
“Hydrolyzed collagen is absorbed in small peptides in the blood.”
Study: Oesser, S., et al. (1999).
Collagen and skin
“Orally ingested hydrolyzed collagen increases the density of collagen in the skin.”
“After 8 weeks, hydrolyzed collagen results in significant improvements of skin elasticity, moisture, and smoothness.”
“Hydrolyzed collagen results in significant improvement in wrinkle depth, improvement in elasticity and hydration of the skin.”
“Hydrolyzed collagen prevents skin damage from UVA and UVB sunlight exposure.”
“Hydrolyzed collagen ingestion increases skin collagen types I and IV, and potentially reduces aging changes in skin.”
“Experiments demonstrated that collagen peptides induce collagen as well as glycosaminoglycan production. The oral supplementation with collagen peptides is efficacious to improve hallmarks of skin aging.”
“Collagen peptide ingestion results in more collagen-producing cells and increases the density of collagen in the skin.”
Study: Borumand M, Sibilla S. Effects of a nutritional supplement containing collagen peptides on skin elasticity, hydration and wrinkles. J Med Nutr Nutraceut 2015;4:47–53. JMNN.ORG
Collagen and joints
“10g of hydrolyzed collagen per day decreases joint pain, especially for those with the most severe symptoms.”
“24 weeks of hydrolyzed collagen use significantly reduced joint pain in a study of 147 athletes.”
Study: Change in knee osteoarthritis cartilage detected by delayed gadolinium enhanced magnetic resonance imaging following treatment with collagen hydrolysate. PMID 21251991
Collagen and bone density
“10g of hydrolyzed collagen for 4 to 24 weeks increases bone mass density.”
Study: Nomura Y., Oohashi K., Watanabe et al. Increase in bone density through oral administration of hydrolyzed collagen. J Nutr Sci Vitaminol. 21(11–12):1120–1126. PMID 16308135
Study: Guillerminet F., et al. Hydrolyzed collagen improves bone metabolism and biomechanical parameters in ovariectomized mice: an in vitro and in vivo study. PMID 19895915
“Hydrolyzed collagen strengthens bones by stimulating the creation of bone-forming cells (osteoblasts).”
“The loss of whole body bone mineral density in women taking CC was substantially lower than that of the control group at 12 months in those who completed the study.”
Hyaluronic Acid Studies
“Hyaluronic acid cocktail leads to a significant improvement in wrinkle depth, improvement in elasticity and hydration of the skin.”
Glucosamine & Chondroitin Studies
“Glucosamine stimulates Hyaluronic Acid production, which decreases wrinkles, improves skin hydration and accelerates wound healing.”
“Oral glucosamine supplementation results in 34% reduction in wrinkles.”
“Glucosamine is helpful in reducing symptoms of moderate to severe osteoarthritis and slowing the progression of osteoarthritis.”
