What is it?
It's an essential element that is needed for nerve and muscle functions in the body. It also plays an important role in the acid-base balance.
The recommendation is between 3.1-3.5 grams a day.
Why do we need it?
It is important for acid-base balance, nerve and muscle functions, and for regulating blood pressure. Lack of potassium can lead to fatigue, muscle weakness and a disturbed heart rhythm.
What if I have too much?
It is hard to over consume potassium through food intake, but you can over consume if you're using supplements, so these should be taken with caution. Having too much can cause hyperkalemia - a condition that causes heart rhythm disturbances. Follow the guidelines if you're using supplements. You don't have to worry about getting too much potassium from fruit and vegetables.
