"Potassium is a mineral involved in electrical and cellular body functions. In the body, potassium is classified as an electrolyte. "Potassium is a very important mineral to the human body. It has various roles in metabolism and body functions and is essential for the proper function of all cells, tissues, and organs: 

* It assists in the regulation of the acid-base balance.
* It assists in protein synthesis from amino acids and in carbohydrate metabolism. 
* It is necessary for the building of muscle and for normal body growth." 

"Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong. Magnesium also helps regulate blood sugar levels, promotes normal blood pressure, and is known to be involved in energy metabolism and protein synthesis [2-3]. There is an increased interest in the role of magnesium in preventing and managing disorders such as hypertension, cardiovascular disease, and diabetes. Dietary magnesium is absorbed in the small intestines. Magnesium is excreted through the kidneys."
