Most drs aren't into supplements, with the exception of magnesium for heart issues. Yes, I take metoprolol. I slows my heart rate which helps me feel better. That's about all my cardiologist recommends at this time, unless I want open heart surgery where they replace the heart valve, ablation the heart and put me on alot of meds. No thanks. I feel well enough for a 70+ year old. Also, the open heart idea would only maybe work and for maybe a few years. Good grief. No thanks.
