How it works
Build -- supplies glycine, proline, and hydroxyproline in the ratios needed as raw material for the body's own collagen synthesis in skin, joint cartilage, tendon, and bone matrix
Maintain -- hydrolyzed collagen peptides are studied for supporting connective tissue turnover and joint matrix maintenance during repair and normal wear-and-tear cycles
Exchange -- hydrolyzed collagen peptides are absorbed intact as small di- and tripeptides (including the signature glycine-proline-hydroxyproline sequence) via dedicated peptide transporters, rather than being fully broken down to single amino acids first -- a mechanistic reason hydrolyzed collagen behaves differently in the gut than an equivalent amount of mixed dietary protein
Sense -- circulating collagen-derived peptides are proposed to act as signaling molecules that stimulate fibroblasts to produce more of the body's own collagen and hyaluronic acid, rather than the ingested peptides being directly incorporated into new tissue structurally
Form matters
The same nutrient can be made in very different forms -- and a study done on one form does not automatically apply to another. Methylcobalamin is not cyanocobalamin; magnesium glycinate is not magnesium oxide; a whole-food extract is not the synthetic isolate that was studied. Two things decide whether what is in the bottle behaves like the research: the exact form, and independent lab verification (a Certificate of Analysis) that the form and dose on the label are truly what is inside. Without a COA, you are trusting a label, not the science.
Across your systems
Collagen synthesis has a nutrient dependency chain most people don't see: vitamin C is a required cofactor for the enzymes that stabilize the collagen triple helix, so a collagen-peptide supplement without adequate vitamin C status is working with one hand tied.
