Taking magnesium unnecessarily can cause diarrhea and may be inappropriate for some people, particularly those with impaired kidney function.
If deficiency is suspected, it is better to discuss testing and supplementation with a healthcare professional.
## 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.

* Bananas
* Avocado
* Leafy vegetables
* Yogurt
* Fish
