Microminerals (also known as trace elements) are micronutrients that are chemical elements. They include boron, chromium, cobalt, copper, fluorine, iodine, iron, manganese, molybdenum, selenium, silicon, tin, vanadium, and zinc. They are dietary minerals needed by the human body in very small quantities (generally less than 100mg per day) as opposed to macrominerals which are required in larger quantities. Note that the use of the term "mineral" in this context is to be distinguished from the definition commonly used in the geological sciences. Micronutrients are essential [[element]s only needed by life in small quantities. ...
