Best Zinc for Testosterone: Boosting Male Fertility Naturally

Testosterone is the primary male sex hormone essential for male characteristics and reproduction. For many couples trying to conceive, low testosterone levels in the male partner is the primary reason behind infertility [1].

Testosterone directly impacts sperm production and sex drive, which makes it very important for men trying to conceive [2]. Testosterone levels can decrease due to many factors, such as aging, poor diet and lifestyle, and environment.

There are many treatment options to achieve increased testosterone levels. Besides treatments, a natural way to improve testosterone is by taking fertility nutrients, such as zinc. Scientific reports show that zinc regulates testosterone production and helps in boosting male fertility [3].

Since there are different forms of zinc supplements, the question here is, What is the best zinc for testosterone?

How Does Zinc Improve Testosterone Levels?

Aromatase is an enzyme in the human body that converts testosterone into estrogen. Different factors, such as age, obesity, and chronic alcohol use, increase aromatase activity, resulting in a higher conversion of testosterone into estrogen. This can lead to decreased testosterone levels. When testosterone levels drop, it causes fertility issues like low sex drive and poor sperm health.

Zinc is an essential mineral that plays a vital role in maintaining healthy testosterone levels by inhibiting the activity of aromatase enzymes [4]. This results in decreased testosterone conversion and increased testosterone production.

A 2023 study published in the National Library of Medicine shows that zinc deficiency in males is often associated with low testosterone levels [3]. On the other hand, evidence shows that adequate zinc intake can increase testosterone and improve sperm quality.

Best Form of Zinc For Testosterone

You will not get the same type of zinc from all the zinc supplements, as they are all created differently. Your body can absorb some forms of zinc better than others. Better absorbing zinc types are considered as the best zinc supplements for male fertility.

Here are the best types of zinc for you if you want to raise your testosterone levels naturally.

1. Zinc Picolinate

Your body can absorb zinc picolinate in the highest concentration compared to other forms of zinc. It binds zinc to picolinic acid, which allows its easy absorption in the body [5].

Because of efficient absorption, zinc picolinate is highly effective in raising serum testosterone levels. Zinc picolinate is the best zinc supplement for testosterone boost which people with zinc deficiency and low testosterone can take.

2. Zinc Citrate

Zinc citrate is also an easy-to-absorb type of zinc and is considered among the best types of zinc for testosterone. This form of zinc is also easy to process by the stomach and doesn't cause side effects such as stomach irritation, which you may experience from other forms.

Good absorption and stomach-friendly nature make it a reliable option to treat zinc deficiency and boost testosterone production.

3. Zinc Gluconate

Zinc gluconate is one of the most commonly available forms of zinc in over-the-counter multivitamin supplements. Its absorption rate is low compared to zinc picolinate and citrate, but it is still a good option for improving testosterone levels.

Zinc gluconate is affordable and widely available, which also makes it a convenient choice for many men. Taking fertility supplements that combine zinc with other essential nutrients can effectively boost testosterone levels and support male fertility.

Other Nutrients For Testosterone and Fertility Health

There are other nutrients that also play a role in supporting male fertility and reproductive health. You can combine these nutrients with zinc to maximize fertility benefits. These are:

1. Vitamin D

Vitamin D is important for regulating testosterone levels. A 2023 study reveals that men with higher vitamin D levels tend to have higher testosterone levels as well [6]. The study further shows that a deficiency in vitamin D can negatively affect testosterone production.

Vitamin D and zinc work together in supporting healthy testosterone levels, so it's important to maintain adequate levels of both nutrients.

2. Magnesium

Magnesium is also a vital nutrient for testosterone production. Magnesium plays a role in the synthesis of testosterone and promotes muscle recovery, which is important for overall male health. These properties make magnesium a common ingredient in most fertility supplements.

3. Omega-3 Fatty Acids

Omega-3 fatty acids are a healthy fat that can support overall reproductive health. Studies show that they can improve sperm quality and support testosterone levels [7]. You can expect improved fertility outcomes by combining omega-3 supplements with zinc.

4. Selenium

Evidence shows that selenium is essential for the production of healthy sperm [8]. You can take it with zinc to support reproductive health. Selenium can help improve sperm quality, making it a common ingredient in supplements for male fertility. Additionally, some herbs for increase sperm count may complement zinc supplementation to enhance male fertility.

Recommended Zinc Dosage For Fertility Benefits

The daily recommended intake of zinc for men is about 11 mg [9]. However, it is common to take a higher dose, somewhere between 15 mg to 30 mg per day, if your goal is to improve testosterone levels and enhance fertility.

It is also advised not to exceed 40 mg of zinc daily, as too much zinc can lead to negative side effects such as nausea, reduced immune function, and long term zinc malabsorption in the body.

Experts recommend that you take zinc or other fertility supplements with food or a glass full of water. Doing so can apparently lower the chances of side effects and improve absorption of these nutrients in the body.

The Bottom Line

Lower levels of testosterone impact sperm quality and reduce the chances of conception. There are many medical management options for increasing testosterone levels. Taking nutrients in the form of supplements is a natural way to boost testosterone levels and it shows promising results.

Zinc is a nutrient present in most fertility supplements because of its role in testosterone production. Among different types of zinc, zinc picolinate, citrate, and gluconate are the best-absorbing zinc types. This makes them the best zinc for testosterone and overall fertility health.
