What Are The Most Common Vitamin Supplements?

Vitamin supplements are typically used to enrich an individual's diet and to provide nutrients they may not get from their food. Vitamins can be purchased over-the-counter, and doctors prescribe high-dose vitamin supplements for patients who have nutritional deficiencies. When using any form of vitamin supplement, it is important to read and follow any dosage recommendations on the label. Vitamin supplements could affect the efficacy of certain prescription medications, including those used to treat cancer, so patients should always ask their doctor before taking supplements of any kind.
