Can Red Yeast Rice Cause Insomnia?

Question:
I started taking red yeast rice and soon after developed insomnia. Could my red yeast rice supplement be the problem?

Answer:
As discussed in the Red Yeast Rice Supplements Review, red yeast rice could potentially cause difficulty sleeping in some people — although this does not appear to be a commonly reported side-effect. See the Cautions and Concerns section of the Red Yeast Rice Supplements Review for more information.

Be aware that if you also take CoQ10 (levels of which may be reduced in people taking red yeast rice or a prescription statin medication), this may also cause insomnia in some people.

Are red yeast rice supplements legally permitted to contain statins, like lovastatin, since these are drugs? >>

For two years, I used a red yeast rice brand which ConsumerLab.com's report showed to contain the highest amount of lovastatin. With just one pill per day, it kept my cholesterol lower (down to 205 from 260 before starting). I switched to a supermarket store brand because it was cheaper and my cholesterol jumped to 278 (taking 2 pills per day)! I don't think the store brand had anything in it -- is that possible?
