Multivitamin preparations and their effects

Multivitamins are dietary supplements that contain multiple vitamins and minerals. They are usually taken in the form of pills, capsules or tablets. Multivitamin supplements are used to treat or prevent vitamin deficiencies due to improper diet, certain illnesses, or during pregnancy. Multivitamin supplements can also be used to boost the immune system, increase energy levels, or improve mood. However, there is little scientific evidence to support these claims. Multivitamin supplements are generally considered safe when taken as directed. However, taking high doses of certain vitamins and minerals can cause side effects such as nausea, headaches, and fatigue. Talk to your doctor before taking any multivitamin to determine if it's right for you.
