    Hello Elaine, could you talk about whether CO Q10 is suitable for patients with hyperthyroid symptoms or to avoid?
    background...after 10 years of behaving (except for elevated antibodies), hyperthyroid symptoms are back. TSH level on routine bloodwork 2 weeks ago was .04. Have noticed a few symptoms like slight weight loss, slight running hot and slight loose bowels. They are retesting me and adding FT 3 and 4 test this week. In the meantime, I read on this forum that L-Carnitine and COQ 10 might help with hyperthyoidism. Last week I began taking. Within a couple days I noticed my heart rate even at night was high and felt like it was pounding, waking me up. I thought it was the Graves symptom, but then I read that CO Q10 can increase heart rhythm. I stopped taking it and the symptom went away. Can you tell us more about this supplement and how it can affect the heart?
    thank you

    In hyperthyroidism and in people on statins, COQ10 is very low and causes muscle weakness. COQ10 helps muscles so it helps heart function. It could be that you haven't been hyperthyroid long this time around for COQ10 to have fallen. And if you're taking a multivitamin it may also have COQ10 in it. To be on the safe side I'd stop COQ10 for now or only take early in the day but continue with acetyl-l-carnitine.
    Once I get more caught up I'll write a blog on COQ10. Best, Elaine
