Registry check · Vitamin B12

Does anyone independently verify Vitamin B12 supplements?

2 of 6Vitamin B12 products we checked appear in a third-party certifier’s registry

2 of the 6 Vitamin B12 products on this page are confirmed in NSF Certified for Sport and USP Verified: Nature Made Vitamin B12 1000 mcg Sublingual Fast Dissolve; Thorne Vitamin B12 as Methylcobalamin 1 mg. 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.

This is one of the 8 long-established nutrients where verified options exist, unlike newer arrivals such as NMN or lion’s mane, where 14 of 17 categories have none. If you want a certified Vitamin B12 product, you can actually buy one.

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 Vitamin B12 dose column either way.

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.
