Is Garden of Life collagen third-party tested?
Last reviewed 2026-10-13. Every certification record and Amazon listing below was read on that date, and each links its source. No price is shown.
Garden of Life Grass Fed Collagen Peptides is not on the NSF Certified for Sport list (checked Oct 13, 2026). Garden of Life has 20 NSF listings, and none is a collagen product. So there is no public NSF record for this powder to read. This page links no Garden of Life listing.
What was checked
- NSF Certified for Sport: all 2,570 listings (NSF list). The 20 Garden of Life listings are whey and plant protein, creatine and other products. None has “collagen” in the name.
- The product: Garden of Life Grass Fed Collagen Peptides, unflavored, 28 servings (19.75 oz), Amazon ASIN B07K4SK9SY, read on Oct 13, 2026. The Amazon listing says the powder is third-party tested, but it names no testing body and links no result.
- Not checked: Informed Choice and Informed Sport (their search did not load in this check), and any certificate of analysis the maker sends on request.
What this does not mean
Not being on the NSF list is not a finding that Garden of Life collagen is untested, or that a lot failed. It means only that this check found no public, named third-party record to compare, and no public heavy-metal result for this powder.
