Analysis
This supplement delivers a useful 500mg dose of Vitamin C, primarily as ascorbic acid, with a small addition of 30mg of calcium from calcium carbonate. This calcium helps to lightly buffer the acidity, potentially making it easier on the stomach for individuals sensitive to plain Vitamin C.
What truly sets this product apart is its remarkable affordability, achieving one of the lowest prices per serving in the market. Coupled with an incredibly high number of positive customer reviews, it represents an excellent, practical option for consistent daily Vitamin C intake.
Pros
- Exceptionally economical price per serving
- Moderate 500mg dose suitable for daily maintenance
- Lightly buffered with calcium for gentler digestion
- Extremely high customer satisfaction with tens of thousands of reviews
Cons
- Buffering amount is relatively small compared to fully buffered options, so very sensitive stomachs may still prefer other forms.
- Does not include bioflavonoids or other synergistic cofactors.
Warnings
- Individuals monitoring their calcium intake should account for the small amount of calcium per serving.
- While buffered, very sensitive stomachs may still prefer a more heavily buffered or non-acidic form of Vitamin C.
