Are You Zinc Deficient?
The King Of Minerals
When it comes to minerals, zinc is king among them in relation to testosterone. Studies all over the planet agree on one thing: Zinc is essential to testosterone! One study tested 11 men on various doses of zinc per day for a period of 30 days. Doses were 1.4, 2.4, 3.4, 4.4, and 10.4mg of zinc per day. The study found that when these men were on the lowest dose of zinc, their testosterone levels decreased by 20%!!
Another study involved older guys. It measured blood levels of zinc. What they found was shocking. Men with normal testosterone levels had MUCH HIGHER levels of zinc than those with low testosterone.
The recommended daily dose of zinc is 12 to 15 mg a day, but zinc intake for older men is no more than 6 to 8mg a day. It takes only 10 weeks of this rate of intake to become zinc deficient. If you are one of these men, be sure to take 45 mg of zinc per day to prevent zinc deficiency.
Remember that I talked about estradiol in an earlier newsletter? Well, zinc works by lowering aromatase –the evil enzyme that converts testosterone to estradiol.
Another cool thing zinc does is assist a special enzyme called 17-beta-hydroxysteroid dehydrogenase, which converts androstenedione to testosterone. Because this enzyme needs zinc, low levels of zinc will surely lower your testosterone through this conversion alone.
Androstenedione is an androgen that is directly converted to testosterone, and through the action of hydroxysteroid, they convert back and forth.
Zinc also strengthens the signals of the pituitary gland, which triggers the function of the testes. By improving the efficiency of this function you will also improve testosterone production.
People who are at higher risk of zinc deficiency are:
• regular alcohol drinkers
These three factors are known to reduce your zinc level. Keep in mind that athletes are almost all deficient in zinc because exercise increases ...
