If on a statin are you taking Q 10 supplements?

[Although statins are well-tolerated by most people, they can cause muscle and joint aches. Statins have been found to reduce the amount of naturally occurring coenzyme Q10 in the body.

Because coenzyme Q10 plays a role in muscle cell energy production, some researchers have proposed that taking a coenzyme Q10 supplement might reduce the risk of muscle-related side effects.]
