60 / 100Good

This is a broad once-daily multivitamin formula, but its unusually large capsule serving and contradictory vitamin K entry warrant label caution.

Score before rubric limits: 78.6 / 100.

Scoring criteria

Quantity
100 / 100
At four capsules daily, the formula supplies a broad maintenance-level vitamin and mineral panel for general adults despite modest calcium, magnesium, and potassium amounts.
Form
75 / 100
The formula uses mostly standard vitamin and mineral forms, with vitamin D3 as a recognized useful form but no clear broad absorption or tolerability advantage over ordinary alternatives.
Convenience
55 / 100
The smallest labelled routine is four capsules once daily with a meal, and the 120-capsule container provides 30 such routines.
Label accuracy
40 / 100
The printed vitamin K-1 amount of 120 mg conflicts with its stated 100% Daily Value, which corresponds to 120 mcg.
Formula balance
75 / 100
The formula covers many nutrient categories but combines numerous low-dose extras without a clearly demonstrated complementary balance for a specific target population.
Purity
75 / 100
The label lists ordinary excipients and provides no product-specific contamination or manufacturing-control evidence to support a higher or lower mark.
Cofactors
50 / 100
Several supplemental cofactors are declared at meaningful amounts, but their added benefit within this already broad formula remains uncertain.
