Category average: 75.7 / 100

This is a reasonably complete once-daily B-complex with supportive vitamin C and E, but it uses conventional forms and makes no product-specific stress claim.

Scoring criteria

Quantity
100 / 100
One tablet supplies a reasonable maintenance amount of the listed B vitamins for general adult supplementation.
Form
75 / 100
The listed conventional forms, including thiamine mononitrate, niacinamide, pyridoxine hydrochloride, folic acid, and cyanocobalamin, have no established relevant absorption or tolerability advantage over ordinary alternatives.
Convenience
100 / 100
The labeled routine is one tablet daily, and the two 66-tablet containers provide 132 tablets in total.
Label accuracy
100 / 100
The supplied panel is internally consistent and gives amounts and forms for the substantive listed nutrients without an identified contradiction.
Formula balance
75 / 100
The broad vitamin combination is ordinary and does not show a clear compatibility problem, although its stress-support positioning is not specifically targeted by the formula.
Purity
75 / 100
The product has ordinary tablet excipients and artificial colors, but no verified contaminant or independent product-specific purity problem is supplied.
Cofactors
50 / 100
Vitamin C and vitamin E are declared at meaningful amounts and may complement general nutritional coverage, but added benefit for the marketed stress purpose is uncertain.
