Ingredient Transparency88
Ingredient amounts and the vitamin C and calcium forms are listed. The unspecified bioflavonoid form limits comparison of that part of the formula.
Value For Money74
The vitamin C content compares favorably for the cost. Value for the calcium and bioflavonoid portions remains uncertain.
Customer Satisfaction96
Customer feedback is very positive across many thousands of ratings. The large review base offers a broad view of satisfaction without proving added benefits from the branded preparation.
Product Focus74
The formula centers on vitamin C for normal immune, skin and everyday nutritional needs. Ester-C and bioflavonoids do not establish extra benefits once vitamin C needs are met.
