Vitamin supplements provide specific vitamins or combinations of vitamins in forms such as capsules, tablets, softgels and gummies. They complement dietary intake, not replace a balanced diet.
Different vitamins perform functions that include supporting energy metabolism, immune function, bone health, muscle function and cell protection. The benefit depends on the nutrient and whether your diet provides enough of it.
A multivitamin provides a combination of nutrients, while an individual supplement focuses on a specific vitamin. Your dietary pattern, nutritional needs and professional advice can help determine which option is appropriate.
Usage instructions vary by product. Follow the packaging directions, including any guidance about taking a supplement with food. Avoid combining products without checking their ingredients and total doses.
Not necessarily. Requirements vary with age, diet, health conditions and medication use. High doses of certain vitamins can cause adverse effects, so consult a healthcare professional before starting a supplement, particularly if you are pregnant, managing a medical condition or taking medication.
