Product score

77.5 / 100Very good

Category average: 68.3 / 100
Average for similar products: 78.8 / 100

A practical once-daily multivitamin with broad vitamin and mineral coverage, though it is not a substitute for dietary intake and the seller’s lutein and lycopene claim is not reflected in the supplied panel.

Scoring criteria

Quantity
100 / 100
One tablet provides broad multivitamin coverage for general adult supplementation; lower calcium, magnesium and potassium percentages do not make it inadequate for this role or require it to replace dietary intake.
Form
65 / 100
D3 and folic acid are identified, but the forms of many minerals and other micronutrients are unspecified, leaving relevant absorption and tolerability properties unresolved.
Convenience
100 / 100
The directions specify one tablet daily, and the two-pack title with 300 tablets per container indicates 600 tablets total.
Label accuracy
50 / 100
The supplied panel does not list lutein or lycopene despite the seller description claiming the product has both.
Formula balance
75 / 100
The formula has conventional broad multivitamin coverage, with no supported special strength or concrete incompatibility established for its stated general role.
Purity
75 / 100
No product-specific purity testing or contaminant evidence is supplied, and the listed excipients alone do not establish a defect.
Cofactors
0 / 100
No separately quantified supporting ingredient beyond the formula’s co-primary nutrients is established.
