- 20 g bovine collagen peptides per scoop
- NSF Contents Certified (NSF/ANSI 173) and NSF Gluten-Free

- Scoop included; 4.5 stars from 17,000+ buyer ratings
- Does not mix well in cold drinks, per buyers
- Probiotic dose is small and of uncertain benefit
- No official TikTok Shop listing found
- Made in a facility that also processes several major allergens
Collagen Peptides (Unflavored)

- Unflavored and mixes easily into hot drinks
- Made without dairy or gluten; 0 g sugar
- Huge review base: 4.6 stars from ~70,000 buyer ratings
- Label does not list an amino acid profile
- Paper canister holds only about 14 servings and ships without a scoop, per a TikTok reviewer

Our verdicts
Grass Fed Collagen Peptides
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.
Full review
Collagen Peptides (Unflavored)
The safest choice if you want a plain collagen powder: a full 20 g dose, one ingredient and NSF Certified for Sport status. The science behind collagen for skin is weaker than the marketing suggests, and the small canister is not the cheapest per gram, but few competitors match its verification.
