Collagen Peptides (Hydrolyzed)
WellnessAlso known as: Hydrolyzed Collagen, Collagen Hydrolysate, Collagen Powder
Well-StudiedWhat is Collagen Peptides (Hydrolyzed)?
The most mainstream peptide supplement. Collagen broken down into small, absorbable peptides for oral use. Widely studied for skin, joint, and general connective tissue support.
How it works
Collagen is enzymatically hydrolyzed into small di- and tripeptides that survive digestion and are absorbed into the bloodstream. These peptides may signal fibroblasts to upregulate collagen synthesis and provide building blocks for connective tissue.
