About this product

Ester-C provides 619 mg of vitamin C, supported by 100 mg of rutin and 50 mg of quercetin. The blend is suited to users seeking buffered vitamin C with added flavonoids rather than concentrated rutin.

Calcium and threonic acid amounts are disclosed, which helps clarify the Ester-C contribution. Rutin botanical source, purity, and standardized form are not given.

One capsule supplies the serving and the bottle provides 90 uses. The formula is convenient, though the shorter supply makes it less compelling than the otherwise similar larger bottle.

Product analysis

78 out of 100
A convenient buffered vitamin C and flavonoid capsule with modest rutin. Sparse rutin sourcing and a smaller serving count are the main trade-offs.

AI assessment of the formula, label and price. How scoring works

Nutrient quality87

Buffered Ester-C is a useful form, while rutin and quercetin are generic. Vitamin C is meaningful, while rutin and quercetin provide moderate support.

Ingredient transparency78

Every listed active has a specific amount. Amounts are clear, but flavonoid sources, directions, and excipients are missing.

Customer satisfaction62

The supplied average rating is exceptionally strong and the supplied review volume is small. No qualitative experience themes were supplied, so recurring complaints and purpose fit cannot be verified.

Value for money82

Buffered vitamin C and complementary flavonoids provide good formula quality. The moderate serving cost makes the smaller package less competitive.
