The trillions of cells in our bodies produce the energy that keeps us alive. As they process food and oxygen to create energy, they also release dangerous molecules called free radicals or oxidants. These oxidants can do a lot of damage. What happens inside our bodies is similar to what happens to an apple when it is cut open and exposed to oxygen: it turns brown because oxygen is corrosive. Our bodies have a defense mechanism in the form of antioxidant enzymes, which neutralize free radicals. This defense mechanism works well until our 20's, but as we get older our cells produce more free radicals than our defenses can neutralize. Oxidative stress caused by free radicals has been linked to over 200 illnesses, so this is a major medical concern. Some experts predict that people will soon monitor their oxidative stress as routinely as they are now monitor cholesterol.

Scientists have been researching ways to boost our natural antioxidant enzymes. A diet rich in fruits and vegetables helps, but many experts say it's not enough. This segment discusses a nutritional supplement called Protandim, which has been shown to be very effective in maintaining cellular health. Protandim contains 5 herbs that have been used in ayurvedic medicine for centuries. After 3 months of taking this supplement, a 78 year old man was tested and his cellular health was shown to be similar to that of a 20 year old.
