43.8 / 100Fair

This is a convenient sugar-free electrolyte concentrate, but its modest sodium dose provides only partial replacement during heavy sweating.

Scoring criteria

Quantity
50 / 100
One portion supplies meaningful potassium and magnesium but only 125 mg of sodium, which is clearly partial for electrolyte replacement during intense sweating.
Form
75 / 100
The product uses dissolved mineral salts in a liquid concentrate, which is a usual practical delivery form without an established special absorption advantage.
Convenience
100 / 100
One 0.5-teaspoon portion diluted into 32 ounces follows the stated preparation, and the two 12-serving containers provide 24 portions; daily frequency is assumed because the label does not specify one.
Label accuracy
100 / 100
The quantified mineral panel and dilution directions are internally consistent, including the equivalent two teaspoons per gallon instruction.
Formula balance
75 / 100
The formula combines relevant sodium, potassium, magnesium and chloride, although its overall electrolyte coverage is ordinary rather than demonstrably optimized for heavy sweating.
Purity
75 / 100
The ingredients are plainly disclosed and no specific contaminant or additive problem is identified, but product-specific purity controls are not supplied.
Cofactors
0 / 100
No separately supportive cofactor is declared because the listed minerals are the formula's co-primary electrolytes.
