Potassium

The mineral most people should eat, not mega-capsule.

Potassium is essential for blood pressure and muscle electricity. Supplement pills are capped at tiny doses in many countries for a reason. Potatoes, beans, yogurt, and salt substitutes usually beat a 99 mg tablet.

How to use

Prefer food. If you use a capsule, stay at labeled doses and skip it if you take ACE inhibitors or have kidney disease.
