An interesting article on Glutathione. " Now, let’s actually think this through: GSH is a good thing, the body’s most important endogenous antioxidant/detoxification molecule. The liver makes more GSH in response to oxidative/toxic chemical stress. Substances which raise blood levels of GSH—even a precursor like cysteine—may do so because they increase (or reflect an increase in) oxidative/toxic chemical stress, the body making more GSH to neutralize the increased stress. Therefore, we might actually make things worse with cysteine supplementation. So it’s possible that adding a supplement that increases GSH might do more harm than good, if we fail to consider the body’s exquisite natural system of checks and balances. Let’s consider an analogous situation: Red blood cells are the indispensable oxygen carriers in the blood. If you don’t have enough of them, you have anemia. The body will compensate and make more of them if you deprive it of oxygen. You can do this by, say, moving from New York (close to sea level) to Denver (a mile high), where the oxygen content of the air is lower, and it works. You can also do it by smoking cigarettes, subjecting your body to chronic carbon monoxide poisoning. Ergo, smoking cigarettes can cure anemia!" Read the rest here Let's discuss !
