Q: Lately my primary care physician has started shilling for a combination of fish oil and something called coenzyme Q-10. The promotional material and web page for this supplement have a distinct “too good to be true” aura. Omega-3 fish oil, I gather, is good for you. But what about coenzyme Q-10?
Answer : A First identified in 1957, coenzyme Q-10 (CoQ-10) is a vitamin-like substance found throughout the body, but especially in the heart, liver, kidneys and pancreas.
