Vitamin C is best known for strengthening the immune system. Studies have shown that 5 grams (5000 mg) of Vitamin C can double the rate of key activities of white blood cells, the soldiers of the immune system. Vitamin C also fights heart disease by assisting with cholesterol metabolism. Most people consume Vitamin C in the form of ascorbic acid, but ascorbic acid passes out of the body quickly, so little of it is absorbed. It can also cause gassiness, bloating, and diarrhea. Ester-C® is made from calcium ascorbate formulated through a patented process so that it neutralizes intestinal acids and can therefore be absorbed without discomfort. It also contains a form of calcium, which enhances absorption.
