Description
Vitamins are compounds that you must have for growth and health. They are needed in small amounts only and are usually available in the foods that you eat. Beta-carotene is converted in the body to vitamin A, which is necessary for healthy eyes and skin.
A lack of vitamin A may cause a rare condition called night blindness (problems seeing in the dark). It may also cause dry eyes, eye infections, skin problems, and slowed growth. Your health care professional may treat these problems by prescribing either beta-carotene, which your body can change into vitamin A, or vitamin A for you.
Some conditions may increase your need for vitamin A. These include:
- Cystic fibrosis
- Diarrhea, continuing
- Illness, long-term
- Injury, serious
- Liver disease
- Malabsorption problems
- Pancreas disease
Increased need for vitamin A should be determined by your health care professional.
Claims that beta-carotene is effective as a sunscreen have not been proven. Although beta-carotene supplements are being studied for their ability to reduce the risk of certain types of cancer and possibly heart disease, there is not enough information to show that this is effective.
Beta-carotene may be used to treat other conditions as determined by your doctor.
Beta-carotene is available without a prescription.
Importance Of Diet
For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods. If you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement.
It is documented that people who consume diets high in fruits and vegetables have a reduced risk of heart disease and certain cancers. Fruits and vegetables are rich in beta-carotene and other nutrients that may be beneficial.
Beta-carotene is found in carrots; dark-green leafy vegetables, such as spinach and green leaf lettuce; sweet potatoes; broccoli; cantaloupe; and winter squash. The body converts beta-carotene into vitamin A. Ordinary cooking does not destroy beta-carotene.
Vitamins alone will not take the place of a good diet and will not provide energy. Your body needs other substances found in food, such as protein, minerals, carbohydrates, and fat. Vitamins themselves often cannot work without the presence of other foods. For example, some fat is needed so that beta-carotene can be absorbed into the body.
This product is available in the following dosage forms:
- Capsule

Precautions
Use of beta-carotene has been associated with an increased risk of lung cancer in people who smoke or who have been exposed to asbestos. One study of 29,000 male smokers found an 18% increase in lung cancer in the group receiving 20 mg of beta-carotene a day for 5 to 8 years. Another study of 18,000 people found 28% more lung cancers in people with a history of smoking and/or asbestos exposure. These people took 30 mg of beta-carotene in addition to 25,000 Units of retinol (a form of vitamin A) a day for 4 years. However, one study of 22,000 male physicians, some of them smokers or former smokers, found no increase in lung cancer. These people took 50 mg of beta-carotene every other day for 12 years. If you smoke or have a history of smoking or asbestos exposure, you should not take large amounts of beta-carotene supplements for long periods of time. However, foods that are rich in beta-carotene are considered safe and appear to lower the risk of some types of cancer and possibly heart disease.
