Both bovine and marine collagen offer valuable health benefits, but the better option depends on your personal goals. Marine collagen is sourced from fish and is mainly made up of Type I collagen, which is the most abundant type found in the skin. Because of its smaller peptide size, it is often absorbed more easily by the body and is commonly chosen for supporting skin elasticity, hydration, hair strength and nail health. Bovine collagen, which comes from cows, typically contains both Type I and Type III collagen. These types play an important role in supporting not only skin health but also joints, bones and connective tissues. For this reason, bovine collagen is often considered a more versatile option for overall health and physical support.

The best choice ultimately depends on whether your priority is skin health or overall structural support for the body.
