Fats-soluble
In contrast to water-soluble micronutrients, fat-soluble nutritional vitamins are saved inside the liver and fatty tissues.
To be absorbed, fat-soluble nutritional vitamins should be consumed with dietary fat.

Calcium fortifies bones, aids circulatory perform, and helps nerve exercise and hormonal secretion. Iodine impacts cognitive growth and thyroid well being.
Antioxidant micronutrients—Nutritional vitamins A, C, and E, together with copper, zinc, and selenium—protect the physique from oxidative stress brought on by free radicals. In extra, these free radicals—produced from regular metabolic processes—can hurt tissues, organs, and genetic materials.
Micronutrients in development and growth
In kids, micronutrients are completely important for development as a result of they help mind and immune system growth. In addition they act as catalysts for metabolic reactions and regulate fluid steadiness.
Micronutrients and bodily efficiency
Whereas macronutrients are sometimes on the forefront of dietary concerns for athletes and health lovers, micronutrients additionally play a pivotal position.
