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.
