Side Effects of Q10
What are the
side effects of Q10?
In short, we are
pleased to report that there are very
few significant side effects
of coenzyme Q10 (CoQ10) supplements!
Of
course, as the dose increases, you may expect more to show up.
Below is
a discussion on all the reported side effects from published books and
research literatures.
Reported Side
Effects of Q10
Here is a list
of reported side effects from taking CoQ10:
- nausea
- heartburn
- vomiting
- skin rash
- headache
- fatigue
- flu-like symptoms
- loss of appetite
Notice
that most of these side effects are general in nature. Obviously the
report of skin rash indicated an allergic reaction to this supplement.
(Yes, you can be allergic to even natural supplements.)
Dose as high as 300 mg did not result in significant side effects in
most people.
Theoretical
Interactions with Drugs and Health Conditions
There
is not much study done to see if taking Q10 would make existing health conditions worse. We do not believe
that most of these interactions are significant.
As a matter of fact, CoQ10 supplements have been shown to make many
health problems better!
Nevertheless, here are some theoretical
concerns that have been reported in research literatures.
May thin the blood out
There
are some reports of people bleeding more when they took coenzyme Q10
supplements. However, this is not confirmed in properly designed
studies. Many other factors might have been involved in these cases
other than taking Q10 supplements.
But, if you are taking any
kind of prescription blood thinners, you should have your INR levels
monitored whenever you start or stop any herbs and supplements.
This is the common sense approach.
May change thyroid levels
(hyperthyroidism/hypothyroidism)
For those with
a thyroid disorder, there has been a report of changes in the blood levels of thyroid.
May lower blood sugar levels
Research
studies don't show that Q10 lowers blood sugar level but this effect
has been reported. But, hey, isn't this a good thing anyways?
Bottom Line?
Not much to
worry about with regards to side effects. Enjoy all the health benefits
of taking CoQ10 supplements!
