What happens if you take too much Potassium?
No UL has been set. People with chronic kidney disease, those on certain drugs, and people with type 1 diabetes, heart failure, liver disease or adrenal insufficiency can develop high blood potassium (hyperkalemia). Even healthy people can get hyperkalemia from too much potassium in supplements or salt substitutes. (Source: NIH ODS) [source]
Is Potassium safe during pregnancy and breastfeeding?
The recommended amount in pregnancy is 2,600 mg (teens) and 2,900 mg (women); while breastfeeding it is 2,500 and 2,800 mg. (Source: NIH ODS) [source]
Does Potassium interact with medications or other supplements?
ACE inhibitors (such as benazepril), angiotensin receptor blockers (such as losartan) and potassium-sparing diuretics (such as spironolactone, amiloride) reduce potassium loss and can push levels too high, especially with kidney problems. Loop and thiazide diuretics increase potassium loss and can cause low levels. (Source: NIH ODS) [source]
