CoQ10 with side effect

Posted by iHerb Customer on Sep 10, 2012 | Verified Purchase

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.

Thanks for your feedback!

No results

I took this suplement for one week and I had headaches two hours after. When I stopped, I felt better. No results for me.

Thanks for your feedback!

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

Thanks for your feedback!

BioPerine Might not be good

Posted by iHerb Customer on Jan 15, 2016 | Verified Purchase

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.

Thanks for your feedback!

Doctor's Worst

Posted by iHerb Customer on Mar 06, 2011 | Verified Purchase

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

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.

Thanks for your feedback!
