Potassium
After calcium and then phosphorus, potassium is the third most abundant mineral in the body. In our cells potassium takes on a positive charge and is an essential component which controls water balance and acid/alkali balance within our cells across the whole body. It helps the transmission of nerve impulses, helps control muscle contraction and also helps maintain a healthy blood pressure.
Prime Fifty have used potassium as an additive in their muscle maintenance product as potassium is very much involved in muscle function.
