This is a potent once-daily B-complex with conventional forms, but its 100 mg pyridoxine dose is unusually high for routine long-term use.
Scoring criteria
Quantity
100 / 100One tablet supplies substantial amounts of all listed B vitamins, including adequate supplemental amounts for a general B-complex role.
Form
75 / 100The formula uses conventional pyridoxine hydrochloride, cyanocobalamin, niacinamide, and an unspecified folate form without a clear broad absorption advantage.
Convenience
100 / 100The one-tablet serving and seller's once-daily description support evaluating one tablet daily, and the title states 60 caplets.
Label accuracy
75 / 100The listed amounts are internally consistent, but the photograph has medium reading confidence and the folate form is not specified.
Formula balance
75 / 100The formula covers the principal B-vitamin group but uses a notably high pyridoxine dose without a demonstrated targeting rationale.
Purity
75 / 100No problematic additives or contamination evidence is provided, so purity remains ordinary and unresolved.
Cofactors
0 / 100Calcium carbonate is incidental to the B-complex role and is not a meaningful demonstrated cofactor for this formula.
