A large dose of the testosterone boosting Zinc gives up to 40 percent higher testosterone levels!August 01, 2012

What is Zinc?

Zinc is an essential trace element for humans, animals and plants. It is vital for many biological functions and plays a crucial role in more than 300 enzymes in the human body. 

 

The adult body contains about 2-3 grams of zinc. Zinc is found in all parts of the body: it is in organs, tissues, bones, fluids and cells. Muscles and bones contain most of the body’s zinc (90%). Particularly high concentrations of zinc are in the prostate gland and semen.

Zinc Supplementation

Zinc supplementation enhances testosterone levels. If you give athletes a daily dose of 3 mg zinc sulfate per kg bodyweight, after four weeks they’ll have up to 40 percent more free testosterone in their body. 

The researchers at the Selcuk University in Turkey discovered this when they did an experiment with 10 male wrestlers.

 What did the study show?

The researchers looked at the effect of zinc on highly-trained wrestlers. The subjects had an average age of 19 and had been training five days a week for at least six years so they already had a good potential for a high natural testosterone production.
The test-subjects did weight training only once a week, cross training once a week and wrestling-specific training on the other three days, a total of 5 training sessions.


Before and after the four-week period of zinc supplementation, the researchers got their test subjects to cycle until they reached the point of exhaustion. Before and after the test, the researchers measured the concentrations of thyroxine and testosterone in the wrestler`s’ blood. While under normal conditions, heavy physical exertion lowers the concentration of these hormone levels. The figure below shows how Zinc prevented this from occuring. The supplements also resulted in a 40 percent increase in the amount of free testosterone before the exhaustion test, quite interesting result.

The exact same effect was also seen on the concentrations of thyroxine and free testosterone T3 and T4 in the blood.

Why is Zinc so important? 

A lot of enzymes use Zinc in the processes of hormone production, regulation and for generating energy from fat-cells and carbohydrates of course. 

You see physical exertion requires quite large amounts of zinc, at least this is what the researchers believe. Such large amounts that using a supplement with the right amout of Zinc, for example TestoTurbo can actually help athletes to improve their performance. 

"Physiological doses of zinc supplementation can prove beneficial to performance", the scientists claim.  Zinc is also a part of the popular supplement called ZMA.

In TestoTurbo we included a full clinical ZMA dosing togheter with all the other 16 testosterone boosting ingredients!
