Microminerals, also known as trace minerals, are essential nutrients that the body requires in small amounts for various physiological functions. These include minerals like iron, zinc, copper, selenium, and manganese. Despite being needed in tiny quantities, they play crucial roles in processes such as metabolism, immune function, and the formation of enzymes. A deficiency in microminerals can lead to health issues, as each mineral has specific functions. For example, iron is vital for transporting oxygen in the blood, while zinc supports immune health and wound healing. A balanced diet typically provides sufficient microminerals, found in foods like meat, seafood, nuts, and whole grains.
