Antioxidants are nature’s antidote to oxidative stress, the imbalance between the production of free radicals and the body’s ability to counteract or detoxify their harmful effects. Glutathione is the most important antioxidant and detoxifier of every cell in the body. In addition to neutralizing, preventing, and reversing cellular damage caused by free radicals, glutathione also cleanses vital organs, promotes anti-aging, and rejuvenates skin, hair, and nails. When taken orally, glutathione is not well absorbed. Therefore, injection is the preferred method of this important molecule.
