Royal Green Fish collagen peptides provides 100% pure hydrolysed collagen peptides type 1, sourced from wild-caught fish. Compared to collagen hydrolysate, these collagen hydrolysate peptides are broken down smaller into tripeptides and dipeptides. The short peptides ensure optimal absorption into the body. More than 90% of the collagen found in our bodies is type 1. Collagen is the most abundant protein in the body and is naturally found in the skin, among other places. Free of fillers, no fishy aftertaste and highly soluble.
