Although not conclusive for everyone, there may be a cardiovascular health benefit for certain people especially as we age. Coenzyme Q-10 (CoQ-10) is part of the ubiquinone family and is involved in energy production in the electron transport chain in all cells. It also provides protection for cell membranes against oxidation. CoQ-10 also prevents the oxidation of LDL cholesterol, which is thought to contribute to the formation of atherosclerosis. In humans, CoQ-10 levels decrease with age. Therefore, presumably, because of CoQ-10’s essential role in energy production and ability to protect against oxidative damage that contributes to the aging process, supplementation with CoQ-10 may assist in maintaining vascular health throughout the body. Recent research also shows that CoQ-10 has the ability to reduce fatigue in endurance activity in older humans and people with compromised cardiovascular health. And finally, CoQ-10 has demonstrated the ability to reduce markers of muscle damage from intense exercise, hinting that supplementation may speed recovery from bouts of exercise.
