Scoring criteria

Quantity
100 / 100
One labeled serving provides 1,220 mg of vitamin C, which is an adequate conventional supplemental amount for general adult use.
Form
85 / 100
The buffered mineral-ascorbate form reduces acidity and may improve gastrointestinal tolerability compared with plain ascorbic acid.
Convenience
100 / 100
The label directs one rounded 2.2-gram scoop daily, and the container provides 103 defined powder portions.
Label accuracy
100 / 100
The high-confidence matched panel gives internally consistent serving, vitamin C, mineral, and container information.
Purity
75 / 100
The label lists no unnecessary additives or documented contaminants, but it provides no product-specific testing evidence warranting a higher mark.
Cofactors
50 / 100
Calcium, magnesium, and potassium are declared at meaningful buffering amounts, but their inclusion does not establish a strong added therapeutic benefit.
