marine collagen may help delay some signs of aging, like wrinkles, joint issues, and weakness. Besides the anti-aging benefits, fish collagen also provides an alternative to people who have issues about using other forms of collagen. Marine collagen is a pure form of hypoallergenic protein produced from the skins of fish. Fish skins remaining from food production are thoroughly washed, then hydrolyzed by an acid and a food grade enzyme to yield marine collagen peptides, which have a low molecular weight for easy digestion and absorption.
