Approximately 80% is found in inorganic portion of bones and teeth . Phosphorus is a component of every cell, as well as important metabolites, including DNA, RNA, ATP, and phospholipids . Also important in pH regulation . Food sources include cheese, egg yolk, milk, meat, fish, poultry, whole - grain cereals, and many others . </Li> <Li> Potassium, a very common electrolyte (heart and nerve health). With sodium, potassium is involved in maintaining normal water balance, osmotic equilibrium, and acid - base balance . In addition to calcium, it is important in the regulation of neuromuscular activity .
