No. Most multivitamins contain only small amounts of calcium. To increase your calcium intake, first try to get calcium from food. You can find calcium in dairy products, such as yogurt, cheese and some soy products. Fortified orange and other juices, fortified grains, almonds, dark greens and some types of seafood are other sources. If you can't get enough from food, talk to your health care provider about an over-the-counter calcium supplement.
