66.6 / 100Good

This is a one-capsule broad multivitamin with iron, but its mineral coverage is uneven and directions are not supplied.

Scoring criteria

Quantity
75 / 100
The assumed one-capsule routine supplies substantial amounts of many vitamins and minerals but leaves vitamin D, magnesium, calcium, potassium, and choline notably low.
Form
75 / 100
The formula uses ordinary established forms such as ascorbic acid, cholecalciferol, carbonyl iron, zinc picolinate, and L-selenomethionine without a clear overall absorption or tolerability advantage.
Convenience
100 / 100
The label gives a one-capsule serving, so one capsule daily is assumed because no directions are provided.
Label accuracy
75 / 100
The photographed panel is broadly internally consistent, but medium-confidence reading and missing directions leave ordinary uncertainty.
Formula balance
75 / 100
The formula covers many nutrients together but is unevenly balanced, with high amounts of several vitamins and trace minerals alongside minimal calcium and magnesium.
Purity
75 / 100
No problematic additives or contamination evidence is supplied, while independent quality testing is not identified.
Cofactors
50 / 100
The declared lutein and choline provide potentially complementary roles, but their amounts are small and added benefit is uncertain.
