## What About Potassium?
Potassium is another nutrient commonly blamed whenever muscles cramp.
Severely abnormal potassium levels can affect muscles and the heart, but most people with ordinary nighttime cramps do not need potassium supplements.
Potassium supplements can actually be dangerous when taken unnecessarily, especially for people with kidney disease or those taking certain medications.
A balanced diet is a safer way for most people to obtain potassium.
Foods naturally containing potassium include:
* Potatoes
* Beans and lentils
* Bananas
* Avocado
* Leafy vegetables
* Yogurt
*
