Buffered Vitamin C contains high-purity ascorbic acid buffered with carbonates of calcium and magnesium. Whereas ascorbic acid has a pH of about 3, buffering this vitamin with minerals raises the pH to a more neutral acid-alkaline balance which is helpful in sensitive individuals. Buffered vitamin C is absorbed more gradually than ascorbic acid alone, which can help maintain steadier blood levels of vitamin C compared to a rapid spike and decline seen with regular ascorbic acid. Each capsule contains 500 mg of ascorbic acid.
