Minerals in the body help distribute fluids inside and outside of cells to ensure the appropriate water balance and acid-base balance to support all life processes.


Sodium is important for the maintenance of the body’s fluid and electrolyte balance. It also helps maintain acid-base balance and is essential to nerve transmission and muscle contraction. Sodium is lost through sweat and should be replenished during exercise.


Potassium also plays a major role in maintaining fluid and electrolyte balance. It assists in nerve impulse and transmission and muscle contractions. Fresh fruits and vegetables are the best potassium sources.


Like sodium and potassium, chloride maintains normal fluid and electrolyte balance. It is also needed for a proper digestion. Chloride is abundant in foods as part of sodium chloride (table salt) and other salts.


Magnesium plays an important role in the soft tissues, where it helps build proteins and is necessary for energy metabolism. It works as a catalyst in energy metabolism. 
Magnesium is also involved in muscle contraction and aids in transporting calcium and potassium across cell membranes. 
The best magnesium sources are nuts, legumes, whole grains, chocolate, and green vegetables.
