Marine collagen
Marine collagen is collagen from fish skin and scales, sold as powder, sachets, liquid or tablets.
Short answer Marine collagen is collagen from fish skin and scales, sold as powder, sachets, liquid or tablets. It is mostly type I, the type most abundant in skin. There is no good evidence that it works better than collagen from other sources.
Marine against bovine
Both are hydrolysed into peptides and both are mainly type I. Marine collagen suits people who avoid beef or pork; bovine suits those who avoid fish. Claims that fish collagen is absorbed far better rest on little human evidence.
