Potassium is an essential nutrient used to maintain fluid and electrolyte balance in the body. It also plays a critical role in the transmission of electrical impulses in the heart.

A deficiency in potassium causes fatigue, irritability, and hypertension (high blood pressure).

Signs of high potassium blood levels include weakness, paralysis, and heart palpitations. (2)

High potassium foods include leafy green vegetables, fish, white beans, avocados, potatoes, acorn squash, milk, mushrooms, bananas, and cooked tomatoes. The current daily value (%DV) for potassium is 4700 milligrams (mg), recently raised from 3500mg by the FDA. (1)
