Glutathione: Natural Protection Against Testosterone-Killing Mercury

Glutathione is one of the most important pro-health and anti-aging chemicals in your body.  It is a powerful antioxidant and detoxifier. Glutathione protects your body against heavy metals such as lead and mercury.  In fact, in my link on Fish Safety, I discuss how some people have gene that yields lower levels of glutathione and, therefore, increased levels of methylmercury after ingestion of fish.

Remember also that mercury attacks your precious testosterone, so glutathione is one of your body’s natural testosterone protectors.  Glutathione is involved in dozens of other critical systems and even protects your body’s Vitamin C.  And we know Vitamin C provides critical collagen protection, including that in your skin.

So how do we raise glutathione levels naturally?

1. ALA. Alpha-lipoic Acid also has another huge benefit:  increase one of the body’s primary antioxidants, glutathione. [2]  Raising glutathione levels has remained elusive and alpha-lipoic is one of the few proven ways of doing it.  Alpha lipoic acid will also help many men with their erectile strength, something I discuss in page on Alpha Lipoic Acid and Erectile Dysfunction.

2. Maca. This Peruvian aphrodisiac was found to increase the all-important natural super-antioxidants SOD and glutathione. [3]

3. Avoid Alcohol.  Alcohol consumption decreases glutathione.  Why?  Because alcohol creates a toxin that glutathione must detoxify. [1]

4.  Whey.  Whey protein raises glutathione levels, at least in individuals with various illnesses such as HIV and cystic fibrosis. [4]  Some animal studies, though, indicate that this should be for the general populace as well. [5]  However, almost all store wheys that I have seen are loaded with dangerous excitotoxins and I document that here in my link called No Whey! However, there is an alternative, undenatured or biologically active whey, which I document in my link called Yes Whey if you want more information.

5. Exercise.  Exercise increases the important form of glutathione. [6]  However, it should be kept in mind that this is the body’s natural response to the increased oxidative load that exercise places upon it.

6. Glucose/Sugars/High Glycemic Foods. A number of in vitro study of human epithelial cells showed that increased glucose led to decreased glutathione levels. [7][9]

7. Resveratrol.  Resveratrol increased glutathione in lung epithelial cells that were “smoke depleted”. [8]  Good sources of resveratrol are red wine, peanuts and cocoa. nuts and cocoa.

8. Grape Seed Extract. This potent and relatively cheap supplement can help improve blood flow – always good for erections – and arterial clotting and inflammation. And, just as important, one study found that it raised plasma glutathione levels by 52%! [10] Admittedly, this was in type II diabetics, but it should help virtually any middle-aged or senior male.

9. Nanodelivery Glutathione. Again, glutathione, if taken by itself, is very poorly absorbed. LEF (Life Extension Foundation) has a product with a nonodelivery system that supposedly greatly improves absorption. The product is called “Lipoceutical Glutathione” if you are interested.

10. Magnesium (Deficiency). There is some evidence that correcting a magneisum deficiency could boost glutathione levels. [12] And there is also evidence that increasing glutathione can increase magnesium in some tissues as well. [11]
