Manganese

Atomic Number 25

Why's it so important?

A small amount of manganese is needed to maintain good health. It is used by enzymes in an organism, which are necessary to keep any cell functioning properly. It is almost impossible to have a deficiency of manganese, so it is not necessary to take any supplements for it. However, an excess can cause weakness, sleepiness, tiredness, emotional disturbances, and paralysis.
