Scoring criteria

Quantity
100 / 100
The labelled 1,584 mg vitamin C serving is a substantial supplemental amount for general adult use.
Form
85 / 100
Buffered mineral ascorbate is less acidic than plain ascorbic acid, offering a practical tolerability advantage without an established special absorption benefit.
Convenience
100 / 100
The label directs one rounded half-teaspoon once daily, and the container lists 287 servings.
Label accuracy
100 / 100
The high-confidence matched panel clearly declares vitamin C and the serving amount without an apparent contradiction.
Purity
75 / 100
No product-specific purity testing or quality-control evidence is supplied, so purity remains unresolved.
Cofactors
0 / 100
The small mineral amounts accompany the buffered formulation and do not establish meaningful complementary support.
