Q: What is Glutathione?

A: Glutathione is the most important antioxidant produced by the body. It prevents cellular damage caused by free radicals and peroxides.

Q: Where does Glutathione come from?

A: Glutathione is synthesized in the body from the amino acids cysteine, glutamic acid and glycine. The amino acid cysteine is responsible for the biological activity of this antioxidant. Supplies of cysteine are the rate-limiting factor in Glutathione synthesis by the cells, since cysteine is relatively rare in foodstuffs. Furthermore, if taken as the free amino acid, cysteine is toxic and spontaneously destroyed in the gastrointestinal tract and blood plasma.

Q: Why is Glutathione important?

A: Increasing cellular Glutathione can dramatically raise energy levels, strengthen the immune system, fight inflammation, improve athletic performance, detoxify the body, aid in cellular repair and slow down the aging process.

Q: What depletes Glutathione in the cells?

A. Environmental pollutants, pharmaceutical drugs and a poor lifestyle all lead to lower levels of this antioxidant.

Q: What toxins affect Glutathione levels?

A: Toxins affecting Glutathione include:
  • Acetaminophen (Tylenol) and other pharmaceuticals
  • Acetone, solvents, paint removers, fuels, fuel by-products
  • Pesticides, herbicides
  • Benzopyrenes: From tobacco smoke, barbequed foods, and fuel exhaust
  • Alcohol
  • Housewares: Certain non-stick coating of pans, plastic containers, plastic linings of tin cans and other food packaging·
  • Formaldehyde and styrene: From photocopiers and toner printers·
  • Chlorine in treated water
  • Medical X-rays
  • UV radiation

Q: What lifestyles affect Glutathione levels?

A: Life style factors that deplete this antioxidant include:
  • Poor diet: It has to work hard to cover for missing or insufficient nutrients and antioxidants.
  • Strenuous exercise: Though not a toxic substance it produces many free radicals in the body;·
  • Stress

Q: How can I increase my Glutathione levels?

A: High quality whey protein has been shown to raise Glutathione in the cells. Proserum native whey protein contains the highest levels of the full range of naturally-occurring Glutathione precursors: covalent bonded cysteine, lactoferrin, immunoglobulins, and active peptides.
