This is a high-potency once-daily multivitamin-mineral serving that supplies many nutrients well but is not a substitute for dietary calcium, potassium, or vitamin D.

Scoring criteria

Quantity
100 / 100
Six tablets provide a broadly substantial maintenance-level supply of most listed vitamins and minerals for general adult supplementation.
Form
65 / 100
Vitamin D3 and K1 are identified, but the applicable chemical forms of several substantive minerals and vitamins are unresolved, preventing a confident form advantage assessment.
Convenience
40 / 100
The label directs adults to take six tablets daily with food, and the 180-tablet container provides 30 such servings.
Label accuracy
100 / 100
The published panel is internally consistent with six-tablet servings and contains no established amount contradiction.
Formula balance
75 / 100
The formula is broadly comprehensive but has uneven coverage, including low vitamin D, partial calcium, and very low potassium relative to the larger doses of other nutrients.
Purity
75 / 100
The label lists ordinary excipients and no documented contaminant or independent purity-control evidence is supplied.
Cofactors
50 / 100
Choline, inositol, citrus bioflavonoids, and trace compounds provide plausible complementary roles, but their added clinical benefit in this formula is uncertain.
