Great product

Posted by 5604035473654157701 on Dec 02, 2016

Bought this cause it's better to take 2x of smaller dosage in a day instead of 100mg at one go. Been buying this for months now. I have hashimoto which also cause slower metabolic rate. And since taking this together with digestive enzyme for a few months, I noticed I'm steadily losing weight. Which means my metabolic rate has increased. All good for me. I'm now recommending this to my colleagues who wants to buy coq10. And I've been purchasing this for my parents too.

Dr Best could be a very good brand if could avoid additives like magnesium stearate. This particular the Ubiquinol does not have.

Chest pain

Posted by 5514864812497002227 on Aug 11, 2016

I had a chest pain on the first day that I took, but not so sure so I continued to took them for 1 week but felt the same. Anyone have the same symptom? Is it the side effect? Now I have decided to stop taking this until I find out...
