What is a Testosterone Booster Supplement?

A testosterone booster is a supplement designed to support your body’s hormonal health. It’s filled with nutrients – vitamins, minerals, herbs, antioxidants – specifically chosen to encourage your body to produce more T.

Testosterone-boosting ingredients include zinc, vitamin D, boron, D-Aspartic Acid, Korean Ginseng, and so on. They all boast a strong clinical pedigree in terms of being shown to contribute to more youthful hormone levels – less estrogen (female sex hormone), more testosterone.

Each testosterone supplement you find will be unique. Ingredient numbers and doses can vary a lot. Some manufacturers prefer adding numerous ingredients to expand their formula, while others like to take a more streamlined approach to their supplements.

Ultimately, the best testosterone formula is one with substantial clinical evidence behind it. Showing that it’s safe, reliable and effective.

What T boosters are not is testosterone replacement. Don’t confuse synthetic testosterone or anabolic steroids with testosterone booster supplements. Testosterone boosters are legal and can be safely used by anyone – without needing a prescription.

After you stop using a T booster, your hormones return back to where they were before you started taking the supplement. You don’t get dependant on it. By contrast, TRT and steroids completely stop your natural testosterone production, and may cause severe dependancy in the long-run.

Why Take a Testosterone Booster?

Why should you consider using a T booster? Because testosterone is arguably the most vital hormone in your body. Your strength, vitality, energy levels, confidence, and mood are all closely linked to testosterone. Although you may not “feel it,” testosterone also influences important health parameters like heart health, blood sugar, and others. Keeping a healthy balance between your testosterone and estrogen is paramount for a healthy life.

The issue is that factors such as stress, age, and lifestyle could be hurting your testosterone levels. When your T is affected, so is your physical and mental health.

Nutrition is another factor in keeping your test levels high. Your diet affects the link between testosterone and other hormones in your body.

T boosters work by supplying your body with nutrients that are shown to encourage thriving testosterone levels. Some nutrients specifically improve your T production, while others work to block interfering hormones like cortisol and estrogen from bringing your T down.

Ultimately, taking a testosterone booster can bulletproof your mental and physical well-being – improving all aspects of your life in the process.

Best Testosterone Boosting Ingredients

Although most men experience some degree of testosterone decline as they get older, you’ll be glad to know that age itself is not the problem. It’s your lifestyle choices that are slowly catching up with you. [study1]

This is good news because it means you have control over reversing the decline. And you can most certainly achieve more youthful health.

Regardless of if you are in your 20s, 30s, or 60s, you can take steps to become a better version of yourself – and that’s where testosterone-boosting ingredients come into play.

Not all nutrients in T boosters are the same. The sad reality is that many supplement companies sell empty promises. They give you false hope in order to make a quick buck. You try the supplement for several weeks and nothing happens – you’re left disappointed having wasted your money.

But some of them are of higher quality and will help to improve your low hormone levels. While testosterone boosters are not a miracle pill, and you shouldn’t expect massive improvements from them alone, they can help to get your hormones back on track when combined with a healthy lifestyle.

Some of the best ingredients to look for in a testosterone booster include:

  1. Vitamin D3 – a secosteroid hormone that your body makes from sunlight. A German research paper found that 3,332IU of D3 per day for one year led to significant improvements in T levels in 54 overweight men. [study2] Doses up to 8,000IU per day have been shown to be perfectly safe.
  2. Zinc – an essential mineral that influences hormones, sleep, and mood among others. Over 2 billion people may be deficient according to studies. Zinc supplementation also helps to prevent dips in testosterone levels, along with boosting your libido.
  3. Ashwagandha – an adaptogenic herb that works to reduce the stress hormone cortisol, giving your testosterone more “space” to grow. [study3] In addition, Ashwagandha has been shown to improve sleep, boost physical stamina, and even improve cognitive well-being.
  4. Boron – this is a dietary mineral found in raisins, brazil nuts, and apricots. It helps to strengthen your bones, reduces arthritis pain, and increases free testosterone levels by up to 14.7%, according to studies. [study4]
  5. Indole-3-Carbinol – or simply I3C, is found in vegetables such as broccoli and cauliflower. This compound, which breaks down into smaller compounds in your body after you ingest it through food, helps to block the process of conversion of your testosterone into the female sex hormone estrogen. By doing so, I3C helps to maintain high levels of T naturally in your body.

The 3 Best Testosterone Boosters

The following testosterone boosters are our pick of the very impressive bunch on the market right now.

#1 TestoFuel: Best Overall

Uses high-quality, natural ingredients and is produced by a respected U.K. supplement company, Roar Ambition.

TestoFuel New Bottle

Testofuel has been a market-leading product for younger guys and athletes for years. It’s effective at supporting muscle growth.

Ingredients

Testofuel has been a market leader for many years, and it’s easy to see why. You’ll see all kinds of products and proprietary blends on the internet claiming to be ‘proven by science,’ but oftentimes, these studies are weak and performed on rats.

TestoFuel also makes serious claims, but it backs them up with some pretty solid evidence. We still recommend doing your own research on the studies about ingredients that TestoFuel uses, but here are some of our favorite ingredients in TestoFuel for boosting muscle growth and masculine performance:

  • Oyster extract (100mg)
  • Magnesium Aspartate (200mg)
  • Vitamin D (4000IU)
  • D-Aspartic Acid (2300mg)
  • Asian Panax Ginseng (100mg)
Our TestoFuel Bottle from the back

TestoFuel uses Oyster extract as a convenient way of getting the nutritional goodness of oysters, including a naturally high amount of zinc that is essential for your testosterone production. Magnesium Aspartate is a highly bioavailable form of magnesium that helps increase free testosterone levels in your body. D-Aspartic Acid is added for its famous ability to potentially boost testosterone levels by over 30% in less than a month, although the effects wear off over time.

While TestoFuel is not a cheap product, you get great value out of its ingredients and highly-rated customer service. It can be a little frustrating trying to remember to take 4 capsules each day, but you should quickly get into the swing of it. The libido and performance increase are among the first benefits you should notice, as well as a reduction in belly fat if you stick to a healthy diet.

What do Others Say?

Online TestoFuel reviews show it’s a favorite among pro athletes and average Joes alike, thanks to its high-quality formula. Testimonials range from gym newbies all the way to former Mr. Olympia winner Robby Robinson, showing that this test booster can work for just about anyone.

It’s for men who want a maximum impact immediately and want the very best quality available.

Hunter Test Testosterone Booster

When it comes to Hunter Test, bigger really is better. This testosterone booster has some of the highest dosages of ingredients we’ve seen in any testosterone booster, while still being within the safe limits, making it healthy for daily use.

Hunter Test works to give you:

  • Improved motivation, productivity, and mental performance

  • Higher libido thanks to zinc & ginseng
  • Bolstered immunity with vitamin D3

Hunter Test contains 5,000IU of vitamin D3 – a secosteroid hormone that plays a crucial role in your body’s ability to make testosterone. One study found that vitamin D can boost the anabolic hormone by an average of 20% in 12 months.

Vitamin K2 in Hunter Test works to reduce calcium build-up in your bloodstream to allow more D3 to flow through your body. Magnesium boosts both free and total testosterone levels, and works in both active and inactive individuals. Zinc is added to the formula to keep your testosterone ‘locked’ at a healthy level.

Hunter Test Ingredients

D-Aspartic Acid, as we’ve seen with other products, can increase your testosterone by up to 100%. Asian Ginseng, on the other hand, augments Hunter Test’s ability to enhance your libido & mood, as well as improve sleep quality and healing.

Ashwagandha is an adaptogenic herb that’s shown to enhance everything from muscle strength to stress resilience. Meanwhile, boron and Indole-3-Carbinol work in synergy to suppress the female sex hormone estrogen – helping you to maintain a more youthful testosterone balance.

  1. I’m 18 and I feel like Centrpeak test booster would be the best thing for me, but my question is, will it have an effect on me because of how young I am

    1. Hi Kyle,

      This is a common question we get about Centrapeak. We’ve found it to work particularly well for people under stress and pressure, and those who want to give themselves a mental and physical boost. So, yes, it works regardless if you’re 18 or older.

  2. Why don’t all products come with an estrogen inhibitor? I feel like if I increase my T I’ll also need to decrease my E. Is there a product to take alongside the T boosters that don’t have an E inhibitor already in it?

    1. Hey Owen,

      All 3 products featured in this guide contain natural estrogen inhibitors. Centrapeak, in particular, contains vitamin B6, Luteolin & Indole-3-Carbinol. These compounds have been shown in studies to lower estrogen levels and inhibit the conversion of testosterone to estrogen, reducing the likelihood of “man boobs,” belly weight gain, and other symptoms of high estrogen.

      If you’re a younger guy, then TestoFuel is an even better option since it contains ingredients that support your natural T production while also diminishing the effects of estrogen with a clinical dose of zinc and vitamin B6.

      The third product on the list, Testo Lab Pro, is just as effective when it comes to managing your estrogen levels – whether you’re a young athlete or man in his 50s looking to have a more balanced testosterone-to-estrogen ratio.

      Hope that helps.

  3. Just a quick question, but as an 18 year old, soon to turn 19, TestoLab would seem to be the best for directly increasing testosterone due to the ingredients and focus it has in that particular area. Would that assuming be correct, or is one of the other two better in increasing testosterone levels.

    1. Nicolas,

      At this age it’s unlikely you’d need a T booster anyways, just a solid lifestyle and your T levels should be soaring. That said, TestoFuel and Testo Lab Pro are both great options for younger guys. Both help to nudge your body to make optimal levels of T. If you’re looking to pack on as much muscle as possible naturally, then TestoFuel has a slight edge because its ingredients are more focused on building strength and raw power. Testo Lab Pro is better for libido & performance in our experience – and Centrapeak is best at fighting cortisol and estrogen and keeping your T levels high as you get older.
