3. Product application
L-Cysteine supports the synthesis of the highly antioxidative Glutathione and can also be stored in this chemical form. It therefore plays an important part in detoxification and the resulting protection of several tissues and organs.
According to recent research studies this does not only slow down the natural process of ageing, but also helps in preventing dementia and multiple sclerosis. L-Cysteine has very high preventative potency in helping to prevent major degenerative illnesses.
