I recently discovered a surprising source of anxiety for me and wanted to share my experience so it may help others. It took me a month or so to figure out that over the counter CoQ10 was causing me recurring bouts of anxiety and tachycardia as well as episodic insomnia. I was really surprised to realize this seemingly benign over the counter supplement could have such a powerful influence on me. I noticed the issue while taking 400mg/day.
On the positive side, CoQ10 also gave me periodic days on which I felt really mentally clear, focused and alert. It would be nice to find a sweet spot in which I got the benefit without the anxiety and insomnia. For now, I am not taking it and would recommend you tread lightly if you decide to try it for any of it's purported benefits.
More details on my experience are posted here.
