Coenzyme Q10 (CoQ10) is a nutrient that acts as an antioxidant, which protects cells from damage and plays an important part in the metabolism.
Although CoQ10 can be naturally found in most healthy people, there is some evidence that adding more in the form of CoQ10 supplements may be beneficial. Increasing age and some medical conditions are associated with dropping levels of CoQ10.
CoQ10 has been used to treat many different conditions. There's evidence that CoQ10 supplements can lower blood pressure and is also used to treat heart failure and other heart conditions, possibly helping to improve some symptoms and lessen future cardiac risks when combined with regular medications.
