Best bovine collagen peptides.

How to choose bovine collagen peptides

Bovine collagen is the classic choice: widely studied, mostly Types I and III, and usually the cheapest collagen per gram.

What to check:

• Grass-fed / pasture-raised — common claims, rarely certified. Nice, not essential.
• Halal or kosher certification if that matters to you.
• Single ingredient for unflavored versions.
• Third-party testing for heavy metals.

Is grass-fed collagen better?

There is no evidence it works better. Some people prefer it for animal-welfare reasons.

Is bovine collagen halal?

Only if it is certified halal. Look for a certification mark on the label.
