Registry check · B-Complex
Does anyone independently verify B-Complex supplements?
1 of the 11 B-Complex products on this page is confirmed in USP Verified: Nature Made Super B-Complex with Vitamin C (140 Tablets). 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 B-Complex dose column either way.
The 11 products on this page checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
What B-Complex labels show
Priced per day, these B-complex products run $0.08 to $0.45 — a 5.6× gap between the cheapest and dearest B-complex here, across 9 brands.
Which row that favours is not obvious: Nature Made Nature Made Super B-Complex with Vitamin C (140 Tablets) is cheapest per serving at $0.08, but its serving sits below the median here, so part of that price gap is simply a smaller capsule.
All B-Complex Supplements Compared
B-complex products differ enormously in strength, and B6 is the one to watch: this catalog ranges from 2 mg to 100 mg of B6 per serving, a fifty-fold spread. ⚠ Sustained high-dose B6 is associated with peripheral neuropathy, and the tolerable upper intake level for adults is 100 mg a day from all sources — several “B-50” and “B-100” formulas sit at or near that ceiling. Methylated forms are worth choosing; megadoses are not.

These B-Complex servings are not comparable to each other
Nature Made Super B-Complex with Vitamin C (140 Tablets) states 2 mg a serving and Solgar B-Complex '100' (100 Veg Capsules) states 100 mg, both occupy one row of the same price column. So Nature Made Super B-Complex with Vitamin C (140 Tablets) showing $0.08 a day, the lowest here, may be reporting a smaller serving rather than a better price. Before comparing Nature Made Super B-Complex with Vitamin C (140 Tablets) with Thorne Basic B Complex (60 Capsules), check what each calls a serving.
