One cup of milk contains approximately 300 milligrams of calcium, a cup of plain yogurt around 400 milligrams. Even people who are mildly lactose intolerant often can enjoy small amounts of dairy products, such as yogurt, cheese and lactase-treated milk. People are allergic to dairy products or have severe lactose intolerance can still consume significant amounts of calcium from food. For people unable to obtain sufficient calcium through diet, supplements such as calcium carbonate, calcium citrate, calcium lactate or calcium gluconate can help. Of these, calcium carbonate is most often recommended because it provides the most calcium per tablet.
Calcium citrate is somewhat easier for older people with low stomach acidity to tolerate.
