I heard CoQ10 is good for gums and I ordered Doctor's best. My father said it was pretty good and he wanted to continue to use it. Delivery was also very good.

My wife wants 1200 mg/day for a medical condition. We've found this to be the most economical mg/dollar ratio. It's hard to evaluate the other qualities, but I know my wife appreciates not having to take any more quantities of pills and caplets than she needs to. The only thing that would make it better for our purpose would be if it came as a 600 mg cap.

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.

Dr's Best Co-Enz Q10 400mg/200mg/100mg

I am very happy with this product. My medical condition is unusual and I have a need for large quantities of COEnzQ10. It is so much easier for me to handle the 400mg product than multiple smaller capsules. I also use the 100mg and 200mg caps as a top up if necessary. I've found this brand to be quite good. I would prefer one with Evening Primrose Oil and Omega 3 Oil in it, as for me that is the best combination. This brand is affordable for me and it is my second choice. In Australia CoEnzQ110 is very expensive. I'm also very happy with the speed with which your products have reached me. The quickest was 2 days 13hrs, and never more than 5 days. As an international delivery that is exceptional. Thank you very much. Sincerely, Lucy Kennedy

I order this for my grandmother for the cardiovascular benefits. iHerb always ships quickly and has a very competive price so I recommend them.
