Overview
American Health's Ester-C capsules deliver 500 mg of a non-acidic vitamin C form alongside citrus bioflavonoids, aimed at people whose stomachs react to standard ascorbic acid tablets. The bottle holds 120 capsules, a 60 serving supply at two capsules per serving.
Ester-C is a patented calcium ascorbate complex rather than plain ascorbic acid, which is the basis for the gentler-on-digestion claim. The listing data available here does not break down the bioflavonoid blend further, so treat the citrus bioflavonoid content as a supporting ingredient rather than a headline dose.

Who it's for
