What are normal levels of potassium. And, at what level should a person worry?


The normal range is 3.7 to 5.2 mEq/L. Note: mEq/L = milliequivalent per liter. If your potassium level exceeds the normal top end, your physician should consider your overall health and see if there are any abnormal physical signs that might be due to abnormally high potassium levels.

What Abnormal Results Mean

High levels of potassium (hyperkalemia) may be due to:

Addison's disease (rare)
Blood transfusion
Crushed tissue injury
Hyperkalemic periodic paralysis
Hypoaldosteronism (very rare)
Kidney failure
Metabolic or respiratory acidosis
Red blood cell destruction


Potassium is very important supplement in our body. And keeping the level of potassium in normal is important for good health. Potassium has many natural sources. Many fruits like bananas, oranges, and avocados contain high amounts of potassium. Also vegetables like potatoes, lime beans, tomatoes have potassium in themselves. Salmon, cod and chicken also contain potassium. So there are many sources of potassium in nature, but sometimes people use potassium supplements as well.
Adults should take around 5 mg per day, and this involves 19 year olds and older. If women is pregnant she also can take this amount, but when she is breastfeeding she need a little bit more of potassium in her body.
