Fish collagen is collagen extracted from the bones and skin of fish. Fish collagen from wild caught fish is the purest form of collagen and can be used in supplements, powders and drinks. The source of Skin for Skin fish collagen is wild caught North Sea fish. This is a very sustainable and natural source. The fish is caught for the food industry, whereby the skins and bones are often not used anymore. Skin for Skin uses this waste stream as a source for its fish collagen. Fish collagen from wild-caught fish is the purest form of collagen, without added antibiotics, growth hormones or food destined for fish farming or animal breeding.
