How Does It Work?

Coenzyme Q10 has several different functions within the cells of the body, such as:
  • ATP production -- Coenzyme Q10 is important for the production of ATP, an important molecule in the body. ATP provides the energy for most of the processes within cells. The production of ATP occurs within certain structures in the cells known as mitochondria.
  • Antioxidant effects -- Coenzyme Q10 acts as an antioxidant, protecting cells from oxidation damage from free radicals. It also helps cells "recycle" other antioxidants, such as vitamins E and C.
  • Membrane stabilization -- Coenzyme Q10 may protect and stabilize cellular membranes.
These are just a few of the ways that researchers think this substance may work. As more studies are done, more information will become available.
