NOW Foods Glutathione 500mg

Glutathione is a linear tripeptide composed of cysteine, glycine, and glutamic acid. Found and manufactured in every cell of the body, the highest concentrations of glutathione are found in the heart, muscles, and liver. Known as the master antioxidant, it protects the DNA and RNA of the cells from free radical damage. Glutathione is essential for liver detoxification and healthy immune defences.

  • Glutathione offers very potent antioxidant properties. It is also known as the “master antioxidant” because it is the most abundant and most powerful antioxidant naturally found in the cells. Antioxidants scavenge unstable free radicals that damage critical cell structures like the DNA and the RNA. Free radical damage has been linked with dementias, heart diseases, age-related blindness, premature ageing, and a wide variety of diseases. With active antioxidant protection, Glutathione prevents cell damage to promote healthy ageing and reduce the risk for age-related diseases.
  • Glutathione modulates the immune system for active defences against invading microorganisms and autoimmune processes. People with weakened immune functions have been found to be low in this antioxidant. Supplementing with glutathione has been found to restore healthy immune system functioning in people with recurring infections and autoimmune disorders like rheumatoid arthritis and allergies.
  • Glutathione peroxidase aids the liver in its detoxification processes. Because the liver is responsible for getting rid of toxins from the diet and pollutants, it can get overworked and develop certain liver conditions. Glutathione helps the liver to carry out its functions to reduce work load and prevent liver diseases like cirrhosis and hepatitis.
  • Glutathione is found to recycle other antioxidants for a stronger and more reliable antioxidant defences. It restores the essential antioxidant Vitamin C or ascorbic acid to its usable form and eventually strengthens the body’s natural response against free radical damage.
  • Glutathione’s antioxidant protection supports optimal cardiovascular health, especially when combined with regular exercise and healthy diet. Oxidation of lipids caused by free radicals creates arterial plaques that obstruct blood flow to the heart and other organs. This obstruction of blood flow is a major risk factor for heart diseases like hypertension, aneurysm, atherosclerosis, and ischemic heart disease.

The chemical structure of glutathione is made up of the three amino acids cysteine, glycine, and glutamic acid arranged in a linear form. This water soluble nutrient is known as the “master of all antioxidants” for its powerful free-radical scavenging properties and because it is the most abundant antioxidant found in all cells. It prevents free radicals from causing any damage to important cell structures like the DNA and RNA. Glutathione is found largely in the heart, muscles, and liver. When at work, glutathione can help restore normal cell functions after it has been exposed to toxins, pollutants, stress, infection, radiation, and other elements. For this, it is famous as a natural anti-ageing agent. The body’s production of glutathione begins to decline with age, which hosts a lot of opportunities for free-radicals to speed up the ageing process and stimulate the progression of age-related diseases. Glutathione supplements are formulated to correct age-related glutathione deficiency in the cells and produce anti-ageing benefits. NOW Foods Glutathione is Reduced form, the non-oxidised stable form of Glutathione. It is also fortified with Milk Thistle Extract and Alpha Lipoic Acid for enhanced liver support.
