Answer:
Glutathione Precursor is an undenatured whey protein isolate that is rich in bonded cysteine. Bonded cysteine is a building block or precursor for intracellular glutathione production, so in a nutshell, Glutathione Precursor raises and sustains glutathione levels.
What is glutathione? It is an antioxidant, immune system optimizer, detoxifier, energy restorer, and anti-aging protein. You can learn more about glutathione here.
Now, what does glutathione have to do with male infertility?
Dr. Jimmy Gutman, MD, FACEP, is the world's most published author on the subject of glutathione. In his current bestseller "Glutathione - Your Key To Health", here is what he has to say about glutathione and male infertility on page 203:
"Male infertility is associated with increased oxidative stress and low glutathione levels. Elevated glutathione levels may enhance the quality of sperm and increase fertility."
This conclusion comes at the end of Chapter 23: "Glutathione and the Human Male", and by reading the entire chapter along with the supporting medical studies provides a much clearer picture of the issue of male infertility, oxidative stress, and glutathione.
In this way, taking Glutathione Precursor, by raising and sustaining glutathione in the human male, may be of a positive benefit for males suffering from infertility.
