L-Glutathione and Vitamin Combination

L-Glutathione and Vitamin Combination

Constant exposure to environmental toxins, pollutants and radiation may damage your tissues within your body. Even normal metabolic activities generate substances called reactive oxygen species, or ROS, which have the potential to cause further injury to your cells. L-glutathione and vitamin C help to ameliorate the effects of external hazards and neutralize internally generated substances that could adversely affect your health.


Glutathione, an important antioxidant and detoxifying agent in your tissues, is manufactured from three amino acids: glutamic acid, cysteine and glycine. Glutathione works with 2 enzymes to perform its functions: glutathione peroxidase converts ROS into water molecules, and glutathione-S-transferase binds glutathione to toxic substances so the latter can be excreted from your body. According to nutritionists, cysteine is primarily responsible for glutathione’s antioxidant properties. Thus, when your glutathione levels are low, a lack of cysteine is often the culprit. Cysteine is less common in foods than many amino acids, but you can find cysteine in high protein foods such as meats, cheeses and wheat germ.

Vitamin C

Ascorbic acid, or vitamin C, is found in a variety of foods, including citrus fruits, rose hips and acerola cherries. Vitamin C is a water-soluble nutrient with many functions, but one of its vital roles is to protect other molecules from oxidative damage. It is also involved in maintaining your body’s supply of other antioxidants, such as vitamin E and glutathione. When vitamin C neutralizes ROS in your tissues, it is itself oxidized to a compound called dehydroascorbate. Recycling of dehydroascorbate to vitamin C helps to sustain its antioxidant function.
