Pure Green Coffee Bean Extract is good for blood pressure. It helps in weight loss and thus decreasing the blood pressure. It helps in the blood circulation and the reduction of the body mass index making the body physically fit. The good news is that it lowers both systolic and diastolic.
Definitely check with your doctor, first. If you do try it, you may meed to be closely monitored for extremely low or high BP. Since the extract will affect your blood pressure in some way, it may increase the effects of the losartan or possibly interfere with it. No studies have been done yet, apparently, on the combined interaction effects or side effects when used with that particular extract. Losartan has (so far) 436 known drug interactions and (so far) 1 listed food interaction. You can check it at www.drugs.com or, specifically: http://www.drugs.com/drug-interactions/losartan.html I'm a supplement user, too, but you have to be really careful or you get whammied and blindsided by interactions.
