In General

1. If receiving regular monthly injections of vitamin B 12 , do not take additional oral supplements of vitamin B12 or folic acid without the advice of a health care provider.

2. Do not take more than the recommended doses of any vitamin or mineral without first checking with a health care provider. Although small amounts of these substances are beneficial, large amounts may be dangerous.

3. Ensure that diet is nutritionally adequate, adding foods that naturally supply the needed vitamins and minerals before taking supplements. See a dietician for advice, particularly for special needs such as pregnancy or diabetes.

4. Avoid foods with high zinc or oxalate content if a calcium supplement is being taken because these may interfere with absorption. These foods include nuts, peas, beans, spinach, and soy products.

5. Know that niacin, or vitamin B3, is also effective at lowering lipid levels. The dose for lowering cholesterol, however, is 2 to 3 grams per day, whereas the vitamin dose is only 25 mg per day.

6. When providing a medical or drug history to the physician or dentist, always report vitamins, minerals, herbs, or dietary supplements being taken. If allergies to any dietary supplements are known, be sure to report these also.
