Co Q 10 or Coenzyme Q-10 is involved in thermogenesis (metabolic rate), weight loss, energy production and blood pressure. Many nutritionists would consider Co Q 10 the most important vitamin co-factor discovered, it is necessary for so many vital cellular functions. Everyone should probably supplement this co-factor (never buy from grocery stores or "marts" - for their supplement products are junk) sometime. IF you are taking a statin drug to lower your lipid levels, YOU particularly need to take Co Q-10 daily, as statin drugs are known to particularly lower the Co Q 10 levels of the body. AND it seems just about everyone is being prescribed these statin drugs from regular doctors' offices now (I never do).
