text: Although neither a prescription drug nor an essential nutrient, CoQ is commonly used as a dietary supplement with the intent to prevent or improve disease conditions, such as cardiovascular disorders. CoQ is naturally produced by the body and plays a crucial role in cell growth and protection. Despite its significant role in the body, it is not used as a drug for the treatment of any specific disease.
  Nevertheless, CoQ is widely available as an over-the-counter dietary supplement and is recommended by some healthcare professionals, despite of lack of definitive scientific evidence supporting these recommendations.
