Zinc and PSA

[HeadDoc]

this came in from a recent Life Extension Newsletter. Many mulitples already have 25-30mg of zinc and therefore no more is needed. Annual testing for heavy metals is a good idea regardless.


A report published in the February 15, 2008 issue of The Prostate revealed the discovery of University of Rochester researchers that zinc may have a protective effect against injury to the prostate induced by cadmium. Cadmium is a non-essential heavy metal that occurs in a number of environmental sources, including phosphate fertilizers and the food crops they are used on, industrial byproducts, smelter emissions, and cigarette smoke. Although epidemiological findings have been inconclusive, studies have shown that cadmium can induce prostate tumors in rats, and the element has been found in greater concentrations in cancerous prostate tissue than in normal tissue.

For the current study, University of Rochester School of Medicine and Dentistry epidemiologist Edwin van Wijngaarden, PhD and colleagues utilized information from 442 male participants in the 2001-2002 National Health and Nutrition Examination Survey (NHANES) for whom urinary cadmium concentrations, dietary zinc intake levels, and prostate specific antigen levels were available. Prostate specific antigen (PSA) increases during prostate injury or inflammation, and may predict prostate cancer, although not with complete accuracy.

Although the researchers did not find an association between increased cadmium and elevated PSA among men whose zinc intake was above the median of 12.67 milligrams per day, an association was found in men whose zinc intake was low. In this group, those with above median urinary cadmium levels had PSA levels that were 22 percent greater than those of men with lower cadmium levels. In the low zinc group, an increase of 1 unit of measurement of urinary cadmium was associated with a 35 percent increase in PSA.

“Your health is based on the complex interplay of many factors,” Dr Van Wijngaarden explained. “Environmental exposures play out differently in people. It’s important to identify those subpopulations that may be more sensitive to toxicities.”

Cadmium’s mechanism in the development of prostate cancer is likely to involve genotoxic effects, such as those resulting in reduced DNA repair and greater activation of genes associated with cell proliferation. Zinc stimulates the availability of proteins called metallothioneins which increase cadmium binding, resulting in its removal from circulation and a reduction of its adverse effects.

“Our findings appear to suggest a protective effect of zinc intake on cadmium-induced prostatic injury, which may provide further rationale for investigating the impact of these factors individually and jointly in the etiology of prostate cancer,” the authors conclude.

Just another good reason to take zink along with all the others.
Omega 3's and zink are my top two.

Thanks Doc,

Ive been taking ZMA for years

Thank You for that

I did the ZMA thing for a few months until I realized that the two supplements were very cheap when purchased separately. I did a ZMA trial before starting meds for HRT. Good stuff.

Easy way to check if one have enough zinc.
Drink Zinc Tally.
If tastes like water (no taste) not enough zinc.
If tastes real bad, enough of zinc.

read second half of this article.

I am not able to not to spil that stuff, very liquid, very low surface tension,
so I use 10mL syringe with long needle to transfer it from bottle to the spoon.
