Registry check · Colostrum

Does anyone independently verify Colostrum supplements?

0 of 7Colostrum products on this page appear in a third-party certifier’s registry

We could not confirm a single one of these 7 products in any registry, and none of them claims otherwise. Not one brand here displays a certification mark, so on independent verification all 7 start level.

This is the group the audit found most exposed: 14 of the 17 newer supplements we track have no certified option at all. Every one of the 8 established nutrients checked — B12, omega-3, vitamin D among them — has one. Demand for Colostrum arrived before verification did.

7 checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.

What 7 Colostrum labels show

Priced per day, these colostrum products run $0.12 to $1.73 — a 14× gap between the cheapest and dearest colostrum here, across 6 brands.

Which row that favours is not obvious: NOW Foods NOW Foods Colostrum 500 mg (120 capsules) is cheapest per serving at $0.12, but its serving sits below the median here, so part of that price gap is simply a smaller capsule.

These Colostrum servings are not comparable to each other

between the smallest and largest serving on this page — 500 mg to 3,000 mg

NOW Foods Colostrum 500 mg (120 capsules) states 500 mg a serving and Nutricost Colostrum Powder — 30% IgG (76 servings) states 3,000 mg — both occupy one row of the same price column. So NOW Foods Colostrum 500 mg (120 capsules) showing 16¢ a day, the lowest here, may be reporting a smaller serving rather than a better price. Before comparing NOW Foods Colostrum 500 mg (120 capsules) with Cowboy Colostrum — 1st Milking, Vanilla (40 servings), check what each calls a serving.

How these 7 Colostrum products were ranked

Not one of these 7 colostrum products could be confirmed in the NSF, USP or Informed Sport registries, so verification separates none of them and the ranking falls to cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever colostrum you buy. Full methodology.
