Multivitaminmineral

Multivitamin-mineral supplements are dietary products that combine a range of essential vitamins and minerals into a single dose. They are designed to help individuals meet daily micronutrient requirements and prevent nutrient gaps in people with limited or unbalanced diets. Formulations vary, but common ingredients include vitamins A, C, D, E, K, the B vitamins, and minerals such as calcium, magnesium, zinc, iron, iodine, and selenium. Some products tailor content for specific groups by adjusting iron or iodine levels or removing certain minerals.

These supplements are not intended as a substitute for a balanced, varied diet. They may be used to support nutrient intake in at-risk populations, including older adults, pregnant individuals (under medical guidance), vegetarians and vegans, people with restricted diets, or those with absorption issues. They are typically taken once daily, with meals to improve absorption and reduce stomach upset.

Evidence on health outcomes from multivitamin-mineral use varies. In generally healthy people, regular use has not consistently shown protection against chronic diseases such as heart disease or cancer. They can improve nutrient status in deficient or undernourished individuals, but results for functional health outcomes are mixed and not guaranteed.

Safety and regulation vary by country. Potential risks include excessive intake of fat-soluble vitamins, interactions with medications, and iron-related side effects in those without a deficiency. Labels should disclose ingredients, amounts, and percent daily values. It is advisable to consult a healthcare professional before starting a supplement, especially during pregnancy, lactation, or when taking medications. Third-party quality testing can help verify product contents.
