E. A Supplement that 'Gives Back' to Every Cell in Your Body

Narrator: This is Science Today. Scientists have long known that each cell in our bodies produce energy with the aid of coenzymes like CoenzymeQ10, or CoQ, but our stores of these coenzymes lessen as we age. University of California, Santa Barbara, biochemist Bruce Lipshutz says that replenishing your body's store of coenzymes like CoQ is an easy and effective way to give back to every cell in your body.

Lipshutz: As we age the amount of CoQ in our cells simply drops over time, and that's why it's important to think about it as a dietary supplement given its importance in so many biological functions. I'm not sure that people really see the distinction that CoQ is a unique position because all we're doing is putting back what we're losing as we age.

Narrator: CoQ acts as an antioxidant and boosts our immune systems. Fortunately for Americans, the supplement form of the enzyme is available over the counter, whereas in other countries like Japan, where is it produced, CoQ is only available by prescription. For Science Today, I'm Larissa Branin.
