CoQ10 with side effect
Posted by 5087148742371355707 on Sep 10, 2012
I took about one month and finally decide to quit. It gave me stomach pain and soft diarrhea. My stomach pain didn't go a way until I quit. Not for me.

Capsules with powder not bind the body in a large part of the people. Therefore it is better to use Soft Gel. I'm using a special type called Ubiquinol
BioPerine Might not be good

A doctor said to be careful to avoid “bioperine” which is a black pepper extract. Not only does black pepper have a lot of aflatoxins but it also “raises bio-availability” which means it shuts down liver function.

I took it only for 2 weeks. I tried it with drink of with food and the results were the same. I had problems with my stomach. Just not for me...
BIG PROBLEMS WITH THIS PRODUCT!!
Posted by Reviewer3320645 on May 18, 2015
Something about this product made me break out in large pustules (like boils) on my torso. I had to buy some anti-itch cream just to sleep. It was terrible. Also, I was taking the COQ10 for a sensitive tooth. This has helped me in the past with other COQ10 products, but not this brand. My tooth eventually got almost to the abscess stage, so I wonder if the Doctor's Best COQ10 actually has any COQ10 in it. (The tooth calmed down as soon as I started taking another brand.) Review from 2011. I used it again in 2015 and I haven't had any trouble with the boils, so it must be OK now. And it did help my sensitive tooth to feel better.
Contains Magnesium stearate :-/

This seems like a really good product, but contains magnesium stearate so I will not buy again. Have to get better at checking the products before buying. Bummer!

Gooday,Doctor's Best High Absorption CoQ10 I have taken 3 times and it has made me sick to my stomach each time. I made sure that I took it just after eating. Something is wrong with this product.Rob
