marine collagen vs bovine collagen
Collagen supplements come primarily from marine (fish) and bovine (cow) sources, each offering unique benefits. Marine collagen is rich in Type I collagen and is highly bioavailable, making it excellent for skin, hair, and nail health. Bovine collagen provides both Type I and Type III collagen, supporting not only skin but also joints, muscles, and gut health. This guide offers an evidence-based comparison to help you decide which type—or a combination of both—best meets your health needs.
