Are you a woman who is past menopause?

Some women can find it difficult to obtain the recommended amounts of calcium and vitamin D without supplementation. As you age, bone loss accelerates and calcium needs increase. At the same time, your body's ability to absorb calcium and process vitamin D decreases. Both calcium and vitamin D supplements have been shown to help protect against bone loss.

Do you have any health conditions?

Some health conditions and treatments make it difficult to digest or absorb nutrients. Examples include a disease of your liver, gallbladder, intestine, pancreas or kidney, or a surgery on your digestive tract. In such cases, your doctor may recommend that you take a vitamin or mineral supplement.

Do you take medications?

Antacids, antibiotics, laxatives, diuretics or other medications can interfere with how your body uses nutrients. If you take any of the medications, ask your doctor if a supplement might be right for you. It's important to talk with your health care provider before starting a dietary supplement. He or she can help you understand whether a dietary supplement might be right for you.
