Zinc has a direct effect on testosterone levels as it is necessary for androstenedione to be converted to testosterone.
A deficiency in zinc will decrease the androgen receptors (bad) while increasing estrogen receptors (really bad) and may even increase aromatization of testosterone to estrogen!
It also plays a direct role in your immune system and cell division so as you can probably gather, being even mildly deficient can have a serious impact on your health.
Zinc Deficiency is Common
Imperative to both overall health and healthy T levels, deficiency is unfortunately one of the more common problems facing men today.
In fact, it’s estimated more than 2 billion people worldwide are marginally deficient. (1)
Even if you eat a diet typically rich in Zinc, the odds of you getting enough every single day to keep your testosterone levels maxed out is pretty slim since the body does not have the ability to store it.
One off day with your diet has the potential to send your testosterone tanking harder then a Clayton Kershaw playoff game.
Does Zinc Raise Testosterone Levels?
Western Washington University ran a study where they gave varsity college football players a combination of zinc and magnesium, also known as ZMA.
They found an “improved anabolic hormone profile and muscle function” in these athletes.
That’s incredibly impressive because we are talking about strength trained males in their prime which don’t typically see a significant statistical boost with supplementation. (2)
That’s Great! But Can The Results Be Repeated?
Yup! In a different study, wrestlers who were given a zinc supplement every day for a month, were proven to have significantly higher testosterone levels vs a placebo group.
Because of the heavy training workload on wrestlers, the placebo group actually saw a decrease in their testosterone. (3)
This shows Zinc may actually keep your T levels higher even with an extremely strenuous workload which is a huge plus if you lift weights, run, bike, work a construction job or do any kind of hardcore physical activity.
Ok, but what about the average Joe?
A group of voluntary males who lived a more sedentary lifestyle were subjected to “fatiguing bicycle exercise” for 4 weeks. These males were able to increase both total and free testosterone levels vs the placebo group. (4)
What’s the bottom line?
Zinc seems to be able to not only raise testosterone levels but also protect men from decreased levels due to the stress of exercise and high physical work loads.
It may also lower SHBG (Sex hormone-binding globulin) levels which inhibits testosterone function. (5)
The studies are clear!
If you want to maximize your manhood, supplement with Zinc!
