Zinc and Testosterone

Here is the gist of this article: if you’re low on test, then taking zinc will help you increase your testosterone levels. If you’re already high on test, taking zinc won’t help boost it much more. If you want to discover why this is, keep reading below.

Testosterone and Zinc: The Primary Mineral of the Endocrine System

Zinc is part of the 24 greatest minerals that is essential for our body. Our body is not capable of synthesizing on its own and it doesn’t have a storage system for it – thus you need to obtain sufficient amounts of zinc in a form of dietary supplements or food on a regular basis.

It is involved in various actions of the cellular metabolism, supports healthy growth, upregulates more than 100 enzymes, greatly related to reproductive health system and assist DNA synthesis.

Aside from that, zinc – at some point – can be considered as a testosterone booster, which slows down the aromatase enzyme, therefore decreases the conversion of testosterone into androgen.

So basically, zinc can boost testosterone levels and prevent estrogen from increasing.

It improves testosterone levels among healthy men that are depleted in mineral. But if you have a balanced serum zinc levels, extra supplementation may not give you any benefits, as a matter of fact, too much zinc in the human body is not healthy.

What is a depletion?

To maintain the functions of the most vital endocrine system, you need to have at least 15 mg’s of daily zinc.

This means that you have to eat tons of protein laced animal-products every day, and most importantly, you need to have supplement that has more zinc to ensure that you are getting the sufficient amounts of these minerals (zinc and also magnesium) dissolve through sweat, this is why supplementation is required in all athletes.

These are the clinical research that supports the benefits of zinc supplementation.

In times of strenuous exercise, elite wresters who were given with 3 mg/kg of zinc on a regular basis for one month, were proven having much higher testosterone and thyroid hormone levels compared to the group of placebo which showed normal decrease in both types of hormones because of too much workload, this can be explained by the fact that the group which belongs to the placebo lost large amount of zinc through sweating regularly, and their diets weren’t adequate enough to take back the wasted minerals in the body. However, in terms of the supplementation group, the trend was not only limited to maintaining testosterone, but at the same time increase the free and total testosterone levels from the baseline of these two states; exhaustion and rest.

Similar researchers undergone and repeat the study using 10 young “male volunteers who are sedentary” in 2007 utilizing the same dosage of zinc and the same duration of time. The men were made to perform “fatiguing bicycle exercise” in a span of 4 weeks and just like the past study, zinc supplementation has the ability to sustain and boost total and free testosterone levels, and also thyroid hormones compared to the group that were given placebo pill. These two studies show that among the individuals who workout, zinc supplementation is a great advantage for hormonal health. Because both of these studies show effective results in improving free-testosterone levels, it’s also credible that zinc can depress serum SHBG levels and result to higher testosterone bio-available for the androgen receptors.

Among patients that are diagnosed with chronic renal failure, a condition related to depleted zinc levels, using mega-dosing of 250 mg/day of zinc, resulted to significantly higher serum zinc, testosterone, and LH levels. There is also a study that is made up of 37 infertile-subjects, the men were give undetermined amount of zinc in a period of six months and saw that the subjects who had lower levels of testosterone (less than 48 ng/dL) found out positive increase in DHT and testosterone levels, while among men that had higher testosterone levels (more than 480 ng/dL) found out no significant improvement. Furthermore, nine men conceive a child while they are under study period.

In terms of cell-culture and animal studies, zinc administration was proved to boost testosterone, DHT and LH levels in this study, study, while reducing the action of female-hormone estrogen against receptors by 56%. Another shocking findings was determined in one in-vitro study done on isolated cells which showed that zinc can slow down DHT production, but this isn’t what happen when humans take the supplement orally, as you can see among those studies above.

zinc and testosterone

Does zinc really boost testosterone levels?

Most likely, yes, at least if you have mineral imbalance and/or you exercise all the time. In that case where your zinc levels are already depleted, you can expect an increase in DHT, which isn’t a bad thing at all.

Does it reduce estrogen?

Yes because it always happens among isolated cells.

What’s the most bio-available type of zinc to take?

Other excellent choices would be citrate and orotate.


Every man that wants to optimize their natural hormone should know about the benefits of zinc.

It is the primary mineral found within the endocrine system. Fixing micronutrient deficiencies is by far the most essential factors that contributes to a healthy production of natural T, and it happens that zinc is one of the key minerals so ensure that you have tons of it in your body.
