Are Multivitamins Necessary?

Multivitamins (MVs) are commonly used, but their necessity depends on individual health needs. While they can fill dietary gaps for those with deficiencies or specific medical conditions, they're not a substitute for a balanced diet. Research suggests MVs don't provide extra health benefits for those without deficiencies and may even cause harm if overused. Consulting a doctor is recommended for proper guidance on MV use.
