Marine vs. Bovine Collagen: Which Is Better?

Both come from collagen, just from different animals. Bovine collagen is sourced from cattle; marine collagen is sourced from fish. Both are typically sold as hydrolyzed peptides that dissolve into liquid. The main practical differences are source preference, taste, and price.

Bovine is the most common and often more affordable, and grass-fed bovine is the clean benchmark for people who care about sourcing. Marine collagen suits people who avoid beef or prefer a fish source, though it sometimes carries a faint taste and tends to cost more. Neither is universally "better" — it comes down to your dietary preferences and what source you're comfortable with. People with fish allergies should obviously avoid marine collagen.
