Coenzyme Q10 (CoQ10) is a key component of the mitochondria—the energy-producing units of the cells in your body. Since your heart cells can’t function without energy, they can’t function without CoQ10. † As you age, your body's natural production of CoQ10 declines, making CoQ10 supplementation even more important.
