Are You Getting Enough?
Calcium is the most plentiful mineral found in the body. The teeth and bones contain the most calcium. Nerve cells, body tissues, blood and other body fluids contain it as well.
Many foods contain calcium, but dairy products are the best source. Milk, yogurt, cheeses and buttermilk contain a form of calcium that the body can easily absorb. (Removing the fat will not lower the amount of calcium in a dairy product, so feel free to choose a lower-fat option.) Other sources include green leafy vegetables, salmon and sardines, almonds, and dried beans.
Calcium is also found in many multivitamin-mineral supplements. The amount varies, depending on the supplement. Supplements may contain only calcium, or calcium with other nutrients such as vitamin D. Check the label on the Supplement Facts panel of the package to determine the amount of calcium in the supplement. Your doctor or pharmacist can recommend the right amount of calcium for you.
