Trace elements are mineral nutrients. They are found in smaller amounts in the body (under 50mg/kg body weight).
Some trace elements are essential and need to be part of our diet however only in small amounts. Essential trace elements include:
Chromium, iron, fluoride, iodine, cobalt, copper, manganese, molybdenum, nickel, selenium, vanadium, zinc and tin.
A lack of these essential trace elements can lead to deficiency symptoms, e.g. an iron deficiency can lead to anaemia. Some essential trace elements are components of enzymes.
Many trace elements have toxic effects if consumed in larger amounts than necessary.
