CoQ10: Adverse Effects?

There are no known adverse interactions between CoQ10 and any drug or nutrient. It is generally well tolerated, and no serious adverse effects have been reported with long-tern use. Because safety during pregnancy and lactation has not been clinically proven, CoQ10 should not be used during these times except under the express direction of a physician (this holds true for most if not all supplements).

If you are taking an anticoagulant drug like Warfarin or Coumadin, be aware that Q-Gel Ultra (our 60mg product) and Q-Gel Mega 100 (our 100mg product) each have 150 iu of Vitamin E per softgel. Vitamin E can also act as an anticoagulant -- so you want to be aware of how much Vitamin E you are taking each day. Q-Gel Forte, our 30mg product, has only 6 iu of Vitamin E per softgel and this small amount of Vitamin E should pose no problem for those patients taking either Warfarin or Coumadin. As usual, we do suggest discussing this with your local health care professional.

Regarding the use of Q-Gel CoQ10, (or any Coenzyme Q10 supplement),and patients suffering from autoimmune disorders we received the following comment from one of the senior scientists at Tishcon Corp.

“There is no available evidence whatsoever to indicate that CoQ10 / Q-Gel can be deleterious to persons suffering from autoimmune disorders. This having been said, we must be cognizant of the fact that CoQ10 has been shown in animal studies to restore depressed immune function. If someone is on immuno-suppressive drugs then I would not recommend concurrent administration of CoQ10 to such individuals.”
