NOW Potassium Category
Potassium is needed to regulate water balance, levels of acidity, blood pressure, and neuromuscular function. This mineral also plays a critical role in the transmission of electrical impulses in the heart. Potassium is also required for carbohydrate and protein metabolism.
Scientists have long known that eating a diet high in potassium is associated with a reduced risk of stroke. The potassium–stroke connection has now been strengthened by a study showing that potassium inhibits the function of blood platelets (Hypertension 2004;44:969–73), an effect that would be expected to protect against stroke.
