I started two years ago taking 200 mg a day of Co Q10 and have experienced a significant drop in my blood pressure. Which was not terribly high to begin with, but enough that they wanted to put me on Lisinopril. Which I tried for two weeks and it just about ruined my life with the coughing all night and the episodes of lightheadedness. I’m a little too old to be taking falls.
Thankfully, I rarely have the coughing from that. It occurs once every few days on average for a few minutes.
