Glutathione is a small tri-peptide produced naturally in our cells when certain required elements are present. It functions both as an antioxidant and an antitoxin and is a major defense system against illness and aging. Our glutathione level actually indicates our state of health and can predict longevity. There are more than 60,000 published papers on the beneficial effects of glutathione. In the near future the importance of glutathione will be widely recognized because it has the ability to boost the immune system and fight off the damage of free radicals on the cells. Various daily activities can reduce your glutathione such as stress, exercise, infection, injury and environmental toxins. Your glutathione, or in other words, your body's natural defense against aging and cellular damage decreases by about 10% to 15% every decade! Sources of Glutathione are: asparagus, broccoli, avocados and spinach. All fresh raw fruits and vegetables are good for increasing glutathione levels, particularly cruciferous vegetables such as Brussels sprouts, cauliflower, cabbage and kale. Try to incorporate more of these items into your daily meals.
