What is Glutathione

Glutathione (GsH, l-Glutathione) is a small, but powerful protein composed of three amino acids: Cysteine, Glutamic and Glycine. Research shows that adding Glutathione to your diet can offer some protection against some forms of cancer. This potent antioxidant binds to toxins and transforms them into a form that can be excreted in urine and bile. Studies using intravenous or intramuscular Glutathione have found it to be useful in preventing clot formation during operations and vital to reducing the side effects and increasing the efficacy of chemotherapy drugs.

How does it work?

Glutathione aids in detoxification of the body by binding to toxins such as heavy metals, solvents and pesticides, and transforming them to a form that can be excreted. Studies using intravenous or intramuscular Glutathione have been found to increase sperm count in men with low motility.

Where does it come from?

Dietary Glutathione is found in fresh and frozen fruits and vegetables, fish, and meat.  Asparagus, avocado and walnuts are particularly rich dietary sources of Glutathione. Raw eggs, garlic and un-denatured whey protein are some other sources of GsH.

Safety / Side Effects

No side effects or interactions are known with oral administration of Glutathione.

Studies Involving Sperm

Eleven infertile men were treated with Glutathione (600mg/day 1m) for two months.  The patients were suffering from dyspermia associated andrological pathologies.  Standard semen and computer analysis of sperm motility were carried out before treatment and after 30 and 60 days of therapy.  Glutathione exerted significant effect on sperm motility patterns.
