"The Encyclopedia of Nutritional Supplements" (C) 1996 has a whole chapter on CoQ10 with more than 20
references. There is more CoQ10 in the heart muscle than anywhere else. There are studies that say
it does help your heart. There are studies that say if you take statins, it depletes the CoQ10 in your body.
Had a heart attack in 1992, have had a defibrillator for 10+ years now. Two years ago, my ejection fraction
was 31%. So for six months I took Entresto, CoQ10, L-Carnitine, and 26 sessions of cardiac rehab.
Got my EF up to 42%. Who's to say which of the four gave me the most benefit?
I've been taking CoQ10 for years.
