Product score

61.9 / 100Good

Category average: 66.1 / 100

This is a convenient single-portion drink mix with declared magnesium, potassium and B6, but the supplied panel does not establish the citrate contribution needed to assess its stone-prevention role.

Scoring criteria

Quantity
75 / 100
The serving provides 170 mg magnesium, 150 mg potassium and 2.6 mg vitamin B6, but no quantified citrate active is identified, leaving adequacy for the stated stone-prevention role unresolved.
Form
65 / 100
The chemical forms of the listed magnesium and potassium are not identified, leaving relevant absorption and tolerability properties unresolved.
Convenience
100 / 100
Directions are not supplied, so I assume one labelled 9.8 g serving once daily; the 40 labelled servings count as 40 measured portions.
Label accuracy
75 / 100
The medium-confidence panel transcription lists no quantified citrate active, so the central stone-prevention formulation cannot be verified; this is unresolved, not an established contradiction.
Formula balance
75 / 100
No concrete incompatibility among the listed components is established, but the formulation’s citrate contribution and role cannot be assessed from the supplied panel.
Purity
75 / 100
No product-specific purity testing or contaminant information is supplied, and no concrete defect is established.
Cofactors
0 / 100
The listed nutrients are assessed as components of the combined formula, and no separate quantified supporting ingredient qualifies for cofactor credit.
