What are the good sources of calcium?

Milk and dairy products are main sources, calcium-fortified bread & cereal, soy milk, juices etc. For non-vegetarians, canned fish can be an additional source.

What about calcium supplements?

Pregnant women are given prenatal vitamins along with calcium so they get around 120-150 mg of calcium in it. If your doctor advises calcium supplements separately, the frequency of consumption is as per your requirements and keeping in mind that the body can only absorb 500 mg of calcium at a time. The calcium supplements are mainly available in two forms:

  1. Calcium carbonate: It provides the most form of calcium, but needs more stomach acid for dissolution. So, it is best to be taken with meals.
  2. Calcium citrate: a lesser amount of calcium provided but more easily absorbed and does not require stomach acid. This is best taken in between meals.
