Minerals : Potassium

Minerals are organic elements present in soil. Plants absorb the minerals from their growth medium. We need very small amounts of each mineral in our diet, but they are essential to maintain all nerve and muscle function, teeth, bones and body cells. Minerals are insoluble in water and need to be bonded with a soluble compound before they can be properly utilised. That is why foods are the very best sources.
