Marine and bovine collagen differ first in their source: marine collagen is usually fish-derived, while bovine collagen comes from cattle. That distinction matters to allergens and dietary preferences. It does not establish that one source is always better.
The complete formula comes first
Check source, allergens and collagen amount per daily serving. A powder, liquid or capsule may also contain vitamins, minerals or flavouring, so compare the complete ingredients rather than the source name alone.
What source types describe
Type 1 or type 3 wording refers to the source material's structural collagen. Hydrolysed peptides are broken down during digestion and do not directly replace the matching collagen type in the body.
Making a practical choice
Consider how the format fits your day and compare current price per equivalent daily serving. Our fuller marine-versus-bovine guide covers these choices in more detail without universal absorption or result promises.
