Studies show that taking CoQ10 can protect cells throughout the body from oxidative stress and protects skin from photo-aging and premature aging, stimulates collagen production, and prevents wrinkles. Taking a CoQ10 supplement could be useful as we age—especially if we are prone to certain health conditions like heart disease, diabetes, certain cancers, and neurodegenerative diseases. CoQ10 is also often prescribed to people with heart failure, high blood pressure, gum disease, Parkinson's disease, blood infections, certain diseases of the muscles, and HIV infection, as they might have lower levels of CoQ10.
