What potassium supports

Potassium helps maintain fluid balance in the body and is commonly considered in wellness plans related to muscle function, post-exercise recovery, and managing dietary sodium intake. It can also be relevant for those tracking minerals more closely, such as athletes or people with higher sweat losses. Always check the label for the total potassium per daily serving, and consider intake from foods such as bananas, potatoes, beans and leafy greens.

How to choose a product
