Trace minerals are essential nutrients that the body needs in small amounts to function properly. These minerals include iron, zinc, copper, selenium, and manganese, among others. They play crucial roles in various bodily processes, such as supporting the immune system, aiding in the production of enzymes, and helping with the formation of red blood cells. Although trace minerals are required in tiny quantities, a deficiency can lead to health issues. For example, a lack of iron can cause anemia, while insufficient zinc may impair immune function. A balanced diet typically provides adequate amounts of these vital nutrients.
