Registry check · Collagen
Does anyone independently verify Collagen supplements?
2 of the 3 Collagen products on this page are confirmed in NSF/ANSI 173: Garden of Life Grass Fed Collagen Beauty (Cranberry Pomegranate); Vital Proteins Collagen Peptides (Unflavored). Garden of Life Grass Fed Collagen Beauty (Cranberry Pomegranate) does not show the mark on the listing, so the table’s certification column, which repeats the listing, does not show it either. For the others, the listing may name a certification, but we did not find it in a public registry — that is not evidence against them, only an absence of independent confirmation.
Certification is not a dosing guarantee. Across the whole catalogue, certified products reach the clinically studied dose 57% of the time and uncertified ones 71% — a gap too small to mean anything (Fisher p = 0.185). Read the Collagen dose column either way.
The 3 products on this page checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
What Collagen labels show
Priced per day, these collagen products run $0.80 to $1.39, across 3 brands.
Which row that favours is not obvious: Sports Research Sports Research Collagen Peptides (Unflavored) is cheapest per serving at $0.80, but its serving sits below the median here, so part of that price gap is simply a smaller capsule.

Dose check · Collagen
Does one serving reach the studied Collagen dose?
The research on Collagen uses 2.5 g to 15 g (hydrolyzed collagen peptides (Type I/III) for skin (2.5-10g), bone (5g), muscle with resistance training (15g)). Every one of the 3 products here reaches the low end in a single serving, so one serving a day covers the studied dose.
The label trap on Collagen: undenatured type II collagen (UC-II) works at just 40mg/day for joints via a different mechanism — grams of hydrolyzed collagen won't deliver the UC-II joint effect, and 40mg is not an 'underdose'
Method: studied range from our own Collagen dosage guide (PMID 16076145), checked against the 3 products above that state a dose — capsules in whole servings, powders in fractions. Trial doses, not a prescription.
How these 3 Collagen products were ranked
2 of these 3 are confirmed in a certifier's registry — the only collagen rows where the claim is independently backed — and the rest are ranked on cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever collagen you buy. Full methodology.
