People who have balanced diets usually do not require dietary supplements. Studies reveal that vitamins and minerals are widely used, but they usually do not help most people stay healthy and are not as good as nutrients found in whole foods. Advisers suggest choosing a healthy mix of foods over depending on pills or powders. If someone has a shortage of nutrients, a health condition, or dietary limits, supplements can be useful, but extra supplements may cause unwanted side effects or interfere with drugs. It is important to get advice from a healthcare professional before you start taking any supplement.
