A well balanced diet is a more natural source of nutrients and it is best to get as much as possible from food. If you are not eating a varied mixture of the main food groups or foods high in a certain nutrient needed for your health situation then make up the remaining through vitamin and mineral supplementation.

  • Vitamin A: 5,000- 10,000 IU. Caution: Do not take vitamin A in sexually active women of child bearing age unless effective birth control is being used due to possible birth defects at high dosages
  • Vitamin C: 500 milligrams three times a day. Caution: Doses of vitamin C larger than 1,200 milligrams a day can produce diarrhea in some people.
  • Vitamin E: 400 IU. Caution: If you are taking anticoagulants, you should not take vitamin E supplements
  • Bioflavonoids: 1,000 milligrams
  • High potency multi-vitamin/mineral formula with extra B vitamins: as directed on the label
  • Zinc: 15-30 milligrams. Caution: Do not exceed a total of 80 milligrams daily from all supplements. Taking over 80 milligrams of zinc daily can weaken the immune system
  • Beta-carotene: 8,300-10,000 IU. Caution: Do not take if you are pregnant. Note: Recent studies have cast doubt on the benefits of getting beta-carotene through supplementation. The best way to take beta-carotene into your body is through foods high in beta-carotene, such as carrots, apricots, cantaloupe, papaya, mangoes, and sweet potatoes.
  • Iron: 18 milligrams
  • Vitamin B6: 2-50 milligrams

In some cases, herbal products can interact negatively with other medications.  Such interactions can be dangerous.  Herbal remedies are not regulated and their quality is not controlled.  Moreover, while there is an abundant supply of information circulating about herbs, not much of it has been scientifically proven.  Consult your physician.  Informing your doctor and pharmacist of what herbal products you are using is just as important as letting them know what drugs you are taking.  Your physician and the pharmacist on duty at your pharmacy can assist you in deciding which herbs
are safe.
