This is a broad one-capsule formula with substantial vitamin doses and iron, but several minerals are low or undisclosed and multiple printed daily values appear unreliable.

Scoring criteria

Quantity
75 / 100
The formula supplies substantial amounts of many vitamins and 10 mg of iron, but calcium, magnesium, zinc, selenium, and some other mineral coverage are clearly partial or low.
Form
65 / 100
Carbonyl iron and zinc picolinate are identified, but forms for most substantive vitamins and minerals are not disclosed, leaving the complex's overall form profile unresolved.
Convenience
100 / 100
No directions are supplied, so one capsule once daily is assumed from the one-capsule serving size and Daily One title.
Label accuracy
40 / 100
Several printed daily values conflict with the listed amounts, including zinc, selenium, niacin, and apparently copper, indicating materially unreliable label arithmetic.
Formula balance
60 / 100
The formula is vitamin-heavy while several minerals are substantially underrepresented or undisclosed, creating an imbalanced broad-spectrum profile.
Purity
75 / 100
No problematic additives or contaminant evidence is supplied, so purity is ordinary but unverified.
Cofactors
50 / 100
The declared 10 mg of FloraGLO lutein provides a meaningful complementary eye-health component, but added benefit beyond the main formula is not established here.
