Calcium is available in two forms, calcium citrate and calcium carbonate. Generally, people with little stomach acid can better absorb calcium citrate, which you do not need to take with food. According to the Office of Dietary Supplements, adult males and females between the ages of 19 and 50 should intake 1,000 mg of calcium per day.
Vitamin D is an essential vitamin that helps the body absorb calcium from foods and supplements and helps maintain proper nerve and muscle function. Vitamin D also assists the immune system in fighting off bacterial and viral infections. Vitamin D supplements are available as ergocalciferol, or vitamin D2, and as cholecalciferol, or vitamin D3.
