Is Garcinia Cambogia Advisable For Weight Loss?

Goodday. I am a healthy 63 yo male. I would estimate I am 20 lbs over my fit weight. I was in my earlier years an athlete (ice hockey player) - meaning even into my late 50 s I was in reasonably good shape. About 3.5 months ago I had a sudden (no previous indicators, trauma or symp s) MPE episode. For which I was briefly hospitalized. Med Team could find no linked causation (diabetes, thyroid, genetic, etc.) however treatment recommendation has been blood thinners (Eliquis) and because I had SVT episodes, Metoprolol Tartrate. So ... my questions are: (1) I am considering a weight loss supplement Garcinia Cambogia to assist in helping to take some of my excess weight (mostly in my torso area) off. But, are there known adverse side effects? (2) The MT for the SVT I experienced seems to have subdued more than the rapid heart beat episodes - it also seems to have brought on ED. Prior to beginning this scrip I had NO issues with ED. So ... I am considering a non-viagra/ non-cialis solution (natural supplements) to assist in this area. THE ULTIMATE GOAL being weight loss + better health = getting off the 2 prescriptions and getting a healthy sex life back without PILLS! Can you comment on the meds and supplements I have outlined and inform of any serious problems I may run into? - Bruce
