What Are Micronutrients? Vitamins and Minerals Explained
Micronutrients are the vitamins and minerals your body needs in small amounts to function properly. Unlike macronutrients, they don't provide energy (calories), but they're essential for processes like immune function, bone health, energy production, and cell repair.
Vitamins vs. minerals
Vitamins are organic compounds produced by plants and animals, split into fat-soluble (A, D, E, K) and water-soluble (B vitamins, C) types. Fat-soluble vitamins are stored in body fat and can build up to excessive levels if overused, while water-soluble vitamins are excreted in urine and need more regular replenishment. Minerals are inorganic elements from soil and water, absorbed by plants or eaten by animals — think calcium, iron, potassium, and zinc.
Why deficiencies happen
Even in places with abundant food, micronutrient shortfalls are common because processed foods are often calorie-dense but nutrient-poor. Restrictive diets, food allergies, and certain medical conditions can also increase the risk of falling short on key nutrients like iron, vitamin D, and B12.
Getting enough through food
A varied diet with plenty of vegetables, fruits, whole grains, legumes, nuts, and lean proteins covers most people's micronutrient needs without supplementation. Colorful produce is a good proxy for variety, since different plant pigments are often linked to different nutrient profiles.

Frequently Asked Questions
Most people who eat a varied diet don't need one, but a multivitamin can be a reasonable safety net for restrictive eaters, older adults, or those with limited food variety. It's not a substitute for real food.
