Our verdict

Our pick for buyers who want independent certification without paying top dollar: 20 g collagen, NSF Contents Certified, NSF Gluten-Free and a published amino acid profile. The probiotic adds little and it does not dissolve well in cold drinks, but the fundamentals are solid.

Best for

  • Shoppers who want NSF-certified collagen at a mid-range price
  • Hot-drink collagen users
  • People who value amino acid transparency

Skip it if

  • Tested athletes needing sport certification
  • Cold-drink users
  • Vegetarians and vegans

Our review

Garden of Life Grass Fed Collagen Peptides is a well-verified, no-frills bovine collagen. One scoop provides 20 g of collagen peptides from bovine hide (18 g protein, 70 calories, 100 mg sodium) plus 250 million CFU of the probiotic Bacillus coagulans SNZ 1969, counted at expiration. The label also prints a typical amino acid profile, including about 3.7 g glycine, 2.4 g proline and 2.1 g hydroxyproline per serving.

Verification is its standout feature. NSF's official listings under NSF/ANSI 173, the standard behind NSF Contents Certified, include Garden of Life Grass Fed Collagen Peptides, meaning the label contents and contaminant limits are independently checked. The brand also carries NSF Gluten-Free certification and IGEN non-GMO testing, and Garden of Life, now part of Nestlé Health Science, has been a certified B Corporation since 2015. It is not certified for sport, so tested athletes should look elsewhere.

The probiotic is a nice extra rather than a reason to buy: the dose is small, and there is little evidence that it improves collagen outcomes. Collagen itself has modest evidence, with skin benefits that shrink in independent, high-quality trials and small-to-moderate joint benefits in osteoarthritis.

The 19.75 oz tub (about 28 servings) costs about $33, roughly $1.17 per 20 g serving or $0.59 per 10 g of collagen, between Orgain and Vital Proteins. It rates 4.5 stars from more than 17,000 buyer ratings. Buyers report that it dissolves well in coffee but not in cold drinks, opinions on taste vary, and a scoop is included.

Questions buyers ask

What does NSF Contents Certified mean for this collagen?
NSF's public listings under NSF/ANSI 173, the dietary supplement standard, include Garden of Life Grass Fed Collagen Peptides. Certification means NSF verifies that the product contains what the label says, screens for specified contaminants and audits manufacturing. It is different from NSF Certified for Sport, which adds banned-substance testing for athletes.
Why is there a probiotic in a collagen powder?
Each scoop includes 250 million CFU of Bacillus coagulans SNZ 1969, a spore-forming strain chosen because it survives in powders; the count is guaranteed at expiration. It is a small dose, and there is little evidence that it changes collagen results, so we treat it as a minor extra rather than a reason to choose this product.
How should I mix Garden of Life collagen?
The label directs one scoop (included) in 8 oz of liquid. Buyers generally report that it dissolves quickly in hot coffee or tea but can clump in cold drinks, so for iced drinks or smoothies stir it into a small amount of warm liquid first or use a blender. It is unflavored, though some buyers notice a mild taste in water.
