Coenzyme Q10 (CoQ10) is an antioxidant that your body produces naturally. Your cells use CoQ10 for growth and maintenance.
Levels of CoQ10 in your body decrease as you age. CoQ10 levels have also been found to be lower in people with certain conditions, such as heart disease.
CoQ10 is found in meat, fish and whole grains. The amount of CoQ10 found in these dietary sources, however, isn’t enough to significantly increase CoQ10 levels in your body.
