Zinc: The Benefits

Of all the “male-specific” minerals, zinc and magnesium get the most attention.

And for good reason – zinc and magnesium (or combined as ZMA) can support natural anabolism, boost recovery, and enhance sleep.

Zinc has enough research and anecdotal evidence for its own article (we’ll look at magnesium, and ZMA, another time).

This is what supplementing zinc can do for your test levels – and how to know if you need it. (Spoiler: you probably do…)

What Is Zinc?

Zinc is one of the 24 essential minerals that our bodies need to survive.

The human body can’t make or store zinc (that’s why it’s called “essential”), so we need to take enough of it every day from food or supplements.

Fortunately zinc supplements are cheap, convenient, and easy to take.

Getting all the zinc you need from your diet is a lot more difficult (although not impossible, if your diet is impeccable 365 days of the year!)

Zinc is found throughout the human body, but muscle and bone tissue contains 90% of the body’s zinc content.

It up-regulates more than 100 enzymes, plays a key role in cellular metabolism, and is strongly connected to testosterone levels.

The testes require zinc to maintain their function. And since men have a greater need for high natural test levels, men also have a more critical need for supplemental zinc intake.

Even a small zinc deficiency has been associated with decreased testosterone levels, low sperm count, and a negative impact on muscle mass.

However, the good news is that supplementing with a daily dose of zinc can quickly reverse all this so you can be on your way to a stronger, leaner, and more fertile body!

How Does Zinc Help The Body Produce Testosterone?

Zinc is a natural way to support and boost the body’s natural levels of free testosterone and growth hormone.

It has been demonstrated that Zinc is able increase levels of luteinizing hormone, a hormone that is released from the pituitary gland to stimulate testosterone production.

It has also been proven to be a significant aromatase enzyme, reducing the conversion from testosterone to oestrogen.


A 1996 study found that zinc plays an important role in regulating the body’s testosterone levels, but we should point out that this study only looked at people who were deficient in zinc. [1]

However, most of us are also deficient in zinc (through poor diet or poor nutrient absorption), so the results of this study are widely relevant.

If you train regularly and experience stress, you are far more likely to be low in zinc than not.

A 2006 study examined the testosterone levels of elite athletes (wrestlers) who had supplemented with a daily supplemental dose of zinc for one month. [2]

They had significantly higher testosterone (and thyroid) levels, compared to a placebo group who saw a reduction in free testosterone.

The conclusion was that both groups lost zinc through sweating during training, and the placebo group who did not supplement zinc were left deficient.

Increased testosterone

The group who did supplement with zinc didn’t only preserve their testosterone, they increased free and total test levels.

If you are deficient in zinc (and you probably are), then supplemental zinc will almost certainly help boost your test levels.

You need at least 15mg zinc every day to maintain absolute basic endocrine system function.

Remember, we lose minerals through sweat. So unless you are consistently getting a lot of zinc from your diet, it’s important to supplement with a quality zinc product.

Low Zinc: Low Testosterone

This 1992 study showed that even short term zinc deficiency can lower testosterone levels in healthy men.

The results of this study suggest that serum testosterone concentrations are sensitive to short-term zinc depletion. [3]

In 2011, a study found that men who have normal test levels also have higher zinc levels than men with low test. [4]

This study was done on male athletes who were involved in intense exercise.

It’s clear that zinc and testosterone levels are closely linked, and that looking after your zinc levels will have a positive impact on testosterone levels if either one is low.

Will Zinc Benefit You?

Everyone needs enough zinc, but it’s particularly important for men (who have higher levels of testosterone, and are more likely to be deficient in zinc due to stress, exercise, and poor diet).

If you have poor gut health, a high stress lifestyle, or if you don’t regularly eat zinc-rich foods (see below), you should supplement with zinc.

And if you have any of the common signs of low test (tiredness, low mood, depression, poor libido, high body fat and/or low levels of muscle tissue), you could definitely benefit from more zinc.

The results from a study which involved American Football players found that when zinc was taken along with magnesium it reduced stress (cortisol) levels and promoted anabolic hormone levels.

Zinc plays an essential role in androgen metabolism and interaction with steroid
receptors.’ [5]

Zinc In Your Diet

Although the best way to optimise your zinc levels is through a quality zinc supplement, some foods can help too.

  • Oysters, lobster, shrimp, prawns, and crabmeat
  • Eggs
  • Beef, chicken, and pork
  • Zinc-fortified cereals and breads
  • Beans and legumes
  • Yoghurt, milk, and cheese
  • Nuts and seeds
  • Oats/oatmeal

Green tea can help the body to absorb zinc. Chlorogenic acid decreases absorption, as does iron (when both iron and zinc exceed 10mg and it is taken on an empty stomach).

What Else Does Zinc Do?

Zinc can help keep your test levels higher in less direct ways, too. As an essential mineral, zinc supports immunity and all-round health (helping to keep you in the gym).

Lower levels of zinc can mean your body’s T-cells are compromised, making you more prone to infection.

If you feel well, you’ll train harder, more often, and more consistently.

  • Zinc plays a key role in cell growth and development
  • It supports the production of white blood cells (mainly T-lymphocytes)
  • Zinc reduces the effect of inflammation on insulin resistance
  • It regulates the neurotransmitter dopamine
  • And can improve your mood, focus, and energy

Furthermore zinc has been shown to improve muscular function when tested on human subjects.

‘Direct muscle function studies with manipulation of zinc status over a short time interval of 3 weeks demonstrated that zinc status positively alters the total work capacity of skeletal muscle in humans.’ [6]

How To Take Supplemental Zinc

Zinc is an essential nutrient, which means you need to get it from your diet or from supplements.

It’s not impossible to get zinc from food, but it is difficult to get precise doses on a regular basis.

And poor gut health, stress, or an imperfect diet can all impact on the amount of zinc you actually absorb.

It makes sense to supplement with zinc (or with an effective testosterone booster) as a very easy, fail-safe way to get the amount of zinc your body needs every day.

A low dose of supplemental zinc is considered to be 5-10mg/day, and this is a decent dose for preventing zinc deficiency.

If you are at higher risk of zinc deficiency, you can take a higher dose of 25-45mg/day.

You can super load zinc, but it’s not advised.

Don’t forget that calcium, magnesium, and iron use the same transporter so can affect the absorption of zinc.

Be sure to take less than 800mg (the transporter’s uptake limit) total of these four minerals at the same time.

Different forms of zinc supplements contain different amounts of elemental zinc (the weight of the zinc molecule).

Here’s how to get 50mg from each different kind of zinc supplement:

  1. Zinc Citrate (146mg)
  2. Zinc Sulfate (220mg)
  3. Zinc Gluconate (385mg)
  4. Zinc Monomethionine (238mg)

Testosterone Boosters with Zinc

All of the best and the most effective testosterone boosters include Zinc for the reasons above.

Therefore, before you buy a natural test booster ensure it includes Zinc, Magnesium and B6.

These three vitamins and minerals are the foundations of a beneficial T-booster.


Zinc is an essential mineral that our bodies can secrete easily. As such it is imperative to regularly top up our levels of zinc

If not, we risk the possibility of reducing our hormone levels, more so if you are an athlete or physically active.

Furthermore, many more bodily functions rely on zinc to operate properly and effectively.

There is simply no reason why you would want to be deficient nor overlook the importance of zinc for your health.
