CoQ10 is essential for energy production in virtually all living organisms. This vitamin-like nutrient plays a crucial role in protecting cells from free radical damage and helping them reproduce.
The cardiovascular system requires high concentrations of CoQ10 due to its great energy demands. But, as we age, production of CoQ10 declines. Some studies have suggested that reduced levels of CoQ10 may contribute to aging, while increased levels may actually slow down the aging process.
