This is not a reflection of the product, I just want to give people a heads up on the potential side effects. I've been taking 100 mg CoQ10 for yrs with no problem. I decided to try increasing the dose to see if I could eliminate my cardiac arrythmias. It was very effective for that! However, I began experiencing very uncomfortable gastrointestinal side effects, as others have reported. Abdominal pain, diarrhea, zero appetite. I also started experiencing increasing muscle tension and pain and headaches both of which became extreme after about a week, and worsening insomnia. I finally figured out what has been causing all these problems and stopped the CoQ10. I'll stay off it for a while then go back to a lower dose. Bummer! Wish I weren't so sensitive to the side effects. It was nice to get rid of my arrythmias.
