An essential mineral nutrient found in the human body in amounts less than 5 grams, also known as micro minerals

3. Interactions
Excess of one may cause a deficiency of another (a slight of manganese overload, may aggravate iron deficiency)
A deficiency of one may interfere with the work of another (a selenium deficiency halts the activation of the iodine-containing thyroid hormones)
A deficiency of a trace mineral may even open the way for the contaminant mineral to cause a toxic reaction (iron deficiency makes the body vulnerable to lead poisoning)

4. A. Iron Ferrous iron (reduced): Fe ++ Ferric iron (oxidized): Fe +++
Both too little and too much in the body can be harmful
Ferrous iron (reduced): Fe ++
Ferric iron (oxidized): Fe +++
Iron as a Cofactor to enzymes involved in oxidation-reduction reaction
