Registry check · Colostrum
Does anyone independently verify Colostrum supplements?
We did not find any of these products in a public registry, and none of the listings names a certification mark. Where a listing names a mark, we say so in the table; where we could not find it in a registry, we say that instead.
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.
The 6 products on this page checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
What Colostrum labels show

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
NOW Foods Colostrum 500 mg (120 capsules) states 500 mg a serving and Cowboy Colostrum — 1st Milking, Vanilla (40 servings) states 3,000 mg, both occupy one row of the same price column. So NOW Foods Colostrum 500 mg (120 capsules) showing $0.12 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 6 Colostrum products were ranked
Not one of these 6 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.
