Would increasing my daily potassium intake help my high blood pressure?

Some medical conditions and medications interfere with the body's ability to excrete excess potassium. Before substantially increasing your potassium intake, check with your doctor if you have diabetes, kidney disease, heart failure, or an adrenal-gland disorder, or if you take any of the following medications: ACE inhibitors, potassium sparing diuretics, or angiotensin receptor blockers (ARBs), such as losartan (Cozaar) and valsartan (Diovan).
