Glutathione is a powerful antioxidant and detoxifies harmful compounds in the liver, which is then excreted through bile.
Like carnitine, glutathione is not actually an amino acid, but because of its close relationships to amino acids, it is described here.
- Glutathione is found in large concentrations in the liver
- The liver also excretes glutathione directly into the bloodstream where it is used to help maintain the integrity of red blood cells, as well as protecting white blood cells
- Glutathione is also found in the intestinal tract where it assists in carbohydrate metabolism as well as breaking down oxidized fats
Since glutathione can be maufactured in the body by a number of other amino acids, deficiency is very rare, but it can occur in the following individuals:
- People on low protein diets - people who are not eating enough protein foods may not get enough glutathione in their diet
- Vegans / vegetarian - people who are on a strict vegetarian diet may suffer from a glutathione deficiency if their diet is deficient in protein
People in these groups at risk of glutathione deficiency should talk to a medical professional about aspartic acid supplementation BEFORE trying them.
- Antioxidant effects - glutathione is also used for its potent antioxidant properties to prevent oxidative stress in cells which helps to neutralise free radicals that can damage and mutate DNA and RNA, which is how cancer spreads throughout the body
Talk to a medical professional about glutathione supplements BEFORE taking them.
