Often called the body’s “master antioxidant,” glutathione takes care of a lot of body business: protecting your cells, supporting detoxification, keeping your immune system humming, and just possibly helping to slow the hands of time (yes, please!). What’s more, your body makes it all by itself. But — and it’s a big but — under certain fairly common circumstances, production can start to sputter. Classic health-eroders like aging, stress, poor diet, and toxic exposure, either on their own or in combo, can all chip away at your natural supply, setting the stage for fatigue and disease far too early in life. Your mission? To keep your tank topped up.
