Product score

81.3 / 100Very good

Category average: 68.3 / 100

A once-daily multivitamin providing many nutrients near their Daily Values; its iron content makes it less universal for adults who do not need supplemental iron.

Scoring criteria

Quantity
100 / 100
One daily tablet provides a reasonable general multivitamin supplement, with many listed nutrients at or near their Daily Values; the lower calcium and magnesium amounts do not make it inadequate for this role.
Form
65 / 100
D3 is identified, but the chemical forms of many other substantive nutrients, including minerals, are unspecified, leaving relevant complex-form properties unresolved.
Convenience
100 / 100
The label directs adults to take one tablet daily with a meal.
Label accuracy
100 / 100
The listed amounts and serving directions are internally consistent, with no evident contradiction or misleading completeness claim.
Formula balance
65 / 100
The formula is broadly conventional, but its 18 mg of iron is not a universally suitable choice for all adults under 50, particularly those who do not need supplemental iron.
Purity
75 / 100
The ordinary excipients are disclosed, but no product-specific purity testing or other quality evidence is supplied.
Cofactors
0 / 100
The other nutrients are part of the multivitamin/mineral formula rather than separately quantified supporting ingredients.
