Which marine collagens are third-party tested?
2 of 8. Informed Choice lists Sports Research Marine Collagen; it buys products from stores and tests them for drugs banned in sport. NSF/ANSI 173 lists Codeage at the same 9 g scoop as the tub. NSF Certified for Sport, Informed Sport and USP Verified list none of the 8. Some brands print “third-party tested” on the tub; that is the brand’s own claim, with no list behind it.
Is marine collagen better than bovine?
On the label they are close, and marine costs more. Per 10 g, both give about 9 to 10 g of protein. The middle marine powder here is $1.06 per 10 g; the plain bovine powders we track cost $0.54 to $0.66 (Amazon prices, and the brand’s own for Sports Research). From the same brand, Sports Research marine is about $11.01 more a month than its bovine at 10 g a day (brand prices). Brands often say marine absorbs better; that is a marketing claim, not a label fact. Pick marine if you don’t eat beef. Types: collagen types compared.
Questions people ask
What is the best marine collagen for women?
The same as for anyone: Codeage Marine Collagen. No powder here has a women’s formula; the collagen is the same. For the lowest price, Micro Ingredients Marine Collagen is $0.68 per 10 g, without a testing list.
What fish is marine collagen made from?
It depends on the brand. The labels we read name cod (Naked, Nutricost, Vital Proteins), Alaskan pollock (Orgain), barramundi or red snapper (Sports Research), and white fish (Codeage, Micro Ingredients). Amandean says only “wild-caught deep sea fish.”
