Best B-Complex Without Cyanocobalamin
B-complex supplements from the NIH Dietary Supplement Label Database whose labels list no cyanocobalamin, ranked by how completely the label discloses what is in the product.
Why People Avoid Cyanocobalamin
Cyanocobalamin is the cheapest, most stable, and best-studied B12, and cells convert it into the same active cofactors as any other form. Its cyanide content is toxicologically trivial at supplement doses.
People choose methylcobalamin, adenosylcobalamin, or hydroxocobalamin instead as a preference for a cyanide-free or naturally occurring form. Heavy smokers and people with advanced kidney disease have a more concrete reason, since both clear cyanide more slowly.
This list keeps only labels that state a B12 form, so the Form column shows exactly what each product uses.
