Zinc and Testosterone Benefits

Testosterone is one of biggest keys to a guy’s well-being. It’s the driving force behind your desire to get out of bed every morning and conquer the world. At the onset of puberty, your body sends out huge quantities of this powerful hormone know as testosterone. It creates muscle and hair growth, a deeper a voice, and feelings of sexual desire. All told, testosterone is essentially responsible for everything that makes you a functioning, healthy male. When testosterone levels are out of the optimal range, you can feel a range of side effects including lethargy, depression, acne, muscle soreness, fat gain. Therefore, it’s important to promote healthy testosterone levels through diet, exercise, and supplementation.

Zinc, one of the bodies most important vitamins, is necessary for optimal testosterone production and healthy function of the male reproductive system. Studies show that zinc supplementation can raise testosterone, and consequently can increase lean mass while lowering fat in those who are deficient. Zinc supplementation has also shown the ability to reduce acne, by promoting healthy skin cell growth.

Zinc deficiency is common, especially among people who do weight training. Stress, caffeine, and alcohol use will also deplete this mineral over time. The average Western diet, due to factors such as lower quality food and increased dry goods/packaged goods, usually, will not provide enough Zinc to maintain healthy testosterone levels.

With these factors in mind, it is not surprising that many of us are deficient in zinc. Even a slight deficiency can manifest in really unpleasant ways. Including: lethargy, low libido, fat gain.

Studies Proving Zinc Testosterone Benefits

There are numerous studies that have examined zinc and discoved it has many legitimate health benefits. Here are some studies showing the zinc testosterone connection.

  1. “Zinc administered within 24 hours of onset of symptoms reduces the duration of common cold symptoms in healthy people…As the zinc lozenges formulation has been widely studied and there is a significant reduction in the duration of cold at a dose of ≥ 75 mg/day, for those considering using zinc it would be best to use it at this dose throughout the cold.” from a PubMed study.
  2. “Dietary zinc restriction in normal young men was associated with a significant decrease in serum testosterone concentrations after 20 weeks of zinc restriction…We conclude that zinc may play an important role in modulating serum testosterone levels in normal men.” from the Wayne State School of Medicine.
  3. From a study designed to test the relationship between zinc and acne, a study showed “During the active treatment period of 6 weeks, the acne improved by about one-third,”.



Zinc for Weight Lifting

Zinc is one of the most important supplements for athletes and especially weight lifters. Any strenuous physical activity depletes the body of Zinc, and a diet lacking in this vitamin and create a deficiency. A deficiency can lead to lower testosterone which will limit muscle growth and increase fat retention.

Controlling Estrogen

Most noteworthy, zinc will lower the amount of testosterone converted to estrogen, functioning as an AI (aromatase inhibitor).

Zinc inhibits the levels of aromatase in the body. If zinc levels are inadequate, the levels of aromatase will rise. The aromatase enzyme must be kept in check, or the side effects of high estrogen start to show up. Increased body fat, bloating, puffy nipples are all very uncomfortable side effects of high estrogen levels. Regular supplementation of Zinc, combined with a healthy diet and a smart exercise routine will keep Estrogen levels in check.


Correcting a zinc deficiency will be a big boost for guys suffering from low libido problems. Your sex drive and even your semen volume will greatly increase. For those suffering from ED, or a low sex drive, Zinc can often do the trick without having to resort to a prescribed option.

Zinc lowers the hormone prolactin. Prolactin is released after you ejaculate. When prolactin levels are high, you will want to roll over after an orgasm and pass out. It’s your bodies natural reaction, to sleep after intercourse. Higher than normal levels can lead to lethargy and weakness. When they are higher, you can recharge faster and have more energy. Going for ’round two’ will be able to happen sooner, as well.

Zinc achieves this by raising testosterone. Higher testosterone is the number one factor for a healthy sex drive.


Zinc has shown to act as a regulator for dopamine. When dopamine levels are low, sex drive is reduced and life just becomes less fun. Keeping your dopamine levels regulated – not too high, and not too low – is essential to your mental stability and happiness. Dopamine pathways are also very important. Zinc deficiency is linked to ADHD and Parkinson’s which are diseases related to dopamine signaling.

Dopamine also plays a role in our bloodstreams as well as your digestive and immune systems. When dopamine is low, there is a ripple effect through many of your body’s systems.

Immune System

Zinc has been shown to reduce the duration and severity of common colds. It’s used by the Thymus gland to promote T cell growth. Therefore, zinc will help your immune system stay healthy. Studies show it’s immune boosting effects in both humans and animals, so it’s no wonder why many cold medications include one form of zinc or another.

The Bottom Line

For everyone, and especially men, getting enough high-quality zinc should be a goal every single day. While zinc and testosterone go hand and hand, the immune system, skin, and fat loss benefits should not be understated.
