This product delivers 1000 mg of Vitamin C per serving in the patented Ester-C Calcium Ascorbate form, which is a buffered and non-acidic type of Vitamin C designed to be gentle on the stomach. It also includes 110 mg of calcium and a significant 400 mg of citrus bioflavonoids complex. Bioflavonoids are plant compounds often found alongside Vitamin C in nature, sometimes believed to enhance its activity and absorption.
Ester-C is often marketed for potentially better retention in the body compared to standard ascorbic acid, aiming for more sustained benefits. As a potent antioxidant, Vitamin C is crucial for protecting cells from environmental stressors. It also plays a key role in collagen formation, supporting the health of skin, blood vessels, and connective tissues. The combination of buffered Vitamin C with a high level of bioflavonoids offers a comprehensive approach to general health, immune function, and antioxidant needs.
