The two types of micronutrients are vitamins and minerals. These micronutrients are important for the proper functioning of different organs in the human body, such as the heart, brain and bones. Similarly, a depletion or lack of these micronutrients, such as vitamin C and iron, can lead to different medical conditions, such as scurvy or anemia, states InnerBody.
Through eating a variety of foods, people can get the recommended daily allowance of most of these micronutrients. Some major vitamins that are important in human nutrition are vitamins A, D, B12. B6, E, C, niacin and folic acid. However, vitamins can be classified as either water-soluble or fat-soluble. Vitamins that are water-soluble are vitamin C and the B-complex vitamins, such as B12 and B6. Because the body does not store water-soluble vitamins, they need to be replaced by eating foods that contain them. Likewise, the body also requires fat-soluble vitamin, which are stored in organs like the liver. Some fat-soluble vitamins are vitamins A and D. Although people require an adequate intake of fat-soluble vitamins, they can cause health problem if taken in excess, reports WebMD.
Minerals are also necessary to maintain the proper function of the body. Some of these minerals are calcium, magnesium and iron. Calcium is necessary for healthy bone, muscle contraction, nerve cells and regulating heartbeat, according to the National Institutes of Health's MedlinePlus. When taking either vitamins or minerals, people should know exactly what are the recommended daily allowance for each micronutrient to avoid either not getting enough or having too much of these important nutrients.
