From what I understand CoQ10 is crucial for many functions of the body. One in particular is the heart - especially for those on statins. I read where statins "suck the CoQ10" out of the heart.
Curlygirl, I hope it helps with your sleep. Not to be pessimistic but I take CoQ10 because I take Lipitor and I have a terrible time sleeping. I'll be interested to see if it helps you. I will say though, I still have tons of energy - sometimes too much. In spite of not getting much sleep I walk 3 miles almost every day - at age 63

God Bless,
