A clearly directed, modest calcium supplement with a sizeable acidifying blend, but the calcium form is not identified and the daily calcium amount is moderate.

Scoring criteria

Quantity
75 / 100
The labelled routine provides 260 mg calcium daily, a meaningful but modest supplemental amount rather than a robust calcium dose.
Form
65 / 100
The calcium compound is not identified, leaving its absorption and tolerability properties unresolved.
Convenience
49.5 / 100
The labelled routine is two capsules twice daily, or four capsules per day; the 100-capsule bottle supplies 25 days.
Label accuracy
100 / 100
The high-confidence FDA-database label gives consistent serving amounts and directions, with no established contradiction.
Purity
75 / 100
The label reports no product-specific contaminant testing or other quality evidence beyond its stated claims.
Cofactors
50 / 100
The 1,048 mg daily acidifying blend is a quantified supporting mixture for the calcium-focused formula, although the individual ingredients and added benefit are uncertain.
