This is the line in the amber bottle with the orange cap, sold under our American Health label. Every formula pairs Ester-C calcium ascorbate with a citrus bioflavonoid complex: citrus bioflavonoids, sweet orange, tangerine, lime, lemon, acerola, rutin and hesperidin, plus naturally occurring vitamin C metabolites.

The amount depends on the unit you pick. A 1000 mg capsule or tablet carries 200 mg of the complex. Two 500 mg capsules or tablets carry 400 mg. Bioflavonoids have no Daily Value, so on your panel they carry two asterisks. If you want them without a capsule shell, choose a tablet. The tablets are labeled vegetarian. The capsules are gluten-free, non-GMO, soy-free, yeast-free and dairy-free.
