I've been using this for about 6-7 months. It increases my energy. There are days when I give my body a rest from Ritalin, my script for energy, & I don't feel tired. Normally when I don't take Ritalin I feel the exhaustion right away.

It doesn't make my heart race or give me a fast heartbeat. I mentioned to my Neurologist that I was using it, & she said she was glad because she had read good reviews about it & was planning on suggesting it to me.

My family doctor has me take it because I take Crestor, a statin, for lowering cholesterol. Statins deplete certain things that CQ10 replaces. I've taken it for years with no problems.

Thank you for the information. U take it every day what mg should I get?

My husband takes 200-300mg CoEnzyme Q10 daily with vitamin that has lots of B vitamins. Take these in the morning otherwise it can keep you up at night.

If you are looking at energy make sure to look at nutrients for thyroid gland, thyroid hormones (Mg, Ca, Iodine, Selenium, etc) and liver, too.

I've been taking 100mg for years even before MS diagnosis. Make sure you get a quality brand. and no it doesn't effect my heartbeat.

good luck :)
