For a powerful boost of antioxidant protection that won't upset your stomach, Swanson Buffered C with Bioflavonoids is an excellent choice.
It features a unique form of Vitamin C that's bonded to calcium through a special process that neutralizes the vitamin's acidity, making it gentler on the stomach--but that's not all. Each capsule also includes 200 mg of natural citrus bioflavonoids that promote efficient assimilation of vitamin C and enhance its antioxidant potency.
Vitamin C (as calcium ascorbate) - 500 mg (556% Daily Value)
Calcium (from calcium ascorbate) - 60 mg (5% Daily Value)
Citrus Bioflavonoid Complex - 200 mg
As a dietary supplement, take one capsule one to two times per day with water or as recommended by your healthcare provider.
