Co-enzyme Q10 (CoQ10) is an antioxidant, which helps vitamins C and E detoxify the superoxide anion. It, like L-arginine, reduces oxidation of cholesterol in the artery walls. "CoQ10 improves shortness of breath and reduces hospitalizations. (Several medications reduce levels of CoQ10, notably statins or cholestrerol-lowering medications..." ("the Cardiovascular Cure", page 212). As we age we produce less CoQ10 so it is particularly unfortunate that we are prescribed statins, which reduce it further. Read more for an excellent new article, but remember L-arginine does everything that statins are claimed to do plus much more and without the side-effects!
Today doctors were formally warned to reduce prescription of aspirin for cardiovascular problems, but, alas, they are being advised to use warfarin and modern blood thinning drugs, rather than L-arginine.
Sadly, most of the time the mainstream media give very bad nutritional advice serving the interests of Big Pharma and the Food Industry. That is why I was so excited to read Giles Coren's article in the Times Magazine.
