Choose a 1000 mg Ester-C if you want one piece a day and nothing to count. The coated tablet is the one most people know from the yellow box. The vegetarian tablet and the capsule come from the bottle line and add 200 mg of citrus bioflavonoids.

All three print the same first line on the panel: vitamin C 1,000 mg, 1,111% of the Daily Value, as Ester-C calcium ascorbate. The calcium that comes with it reads 110 mg on the tablets and 108 mg on the capsule. Pick the coated tablet for the box line and its C-Sorb complex, the capsule if tablets are hard for you, and the vegetarian tablet if you want bioflavonoids without a capsule shell.
