Glutathione is the most critical and integral part of your detoxification system. All the toxins stick onto glutathione, which then carries them into the bile and the stool -- and out of your body.
Glutathione is critical for one simple reason: It recycles antioxidants. Dealing with free radicals is like handing off a hot potato. They get passed around from vitamin C to vitamin E to lipoic acid and then finally to glutathione which cools off the free radicals and recycles other antioxidants. After this happens, the body can "reduce" or regenerate another protective glutathione molecule and we are back in business.
However, problems occur when we are overwhelmed with too much oxidative stress or too many toxins. Then the glutathione becomes depleted and we can no longer protect ourselves against free radicals, infections, or cancer and we can't get rid of toxins. This leads to further sickness and soon we are in the downward spiral of chronic illness.
It also helps us reach peak mental and physical function. Research has shown that raised glutathione levels decrease muscle damage, reduce recovery time, increase strength and endurance and shift metabolism from fat production to muscle development.
