Coenzyme Q10 is exactly what the name implies, an enzyme. It’s already present in the cells of the body, and most prevalent in the heart and liver. Its purpose in the body is to create energy at the cellular level. Certain research claims that Candida toxins, such as aldehydes, have a tendency to stifle the binding of CoQ10 in the cells. Taking a supplement of Q10 isn’t going to cure your infestation, but it certainly won’t do any harm to take a supplement.
