Welcome to our guide to the very best testosterone booster supplements on offer right now. Suitable for both younger guys who want to build strength, as well as older guys who’re looking to help their body regenerate its T levels in a safe, natural and inexpensive way.
Athletes all over the world take supplements to support their T levels naturally. Below you’ll find a list of the best, safest and most reliable formulas to increase your levels of this critical androgen hormone.
Best testosterone boosters use natural ingredients that have been proven to:
- Boost muscle growth and protein synthesis
- Speed up your metabolism (burn unwanted fat)
- Bring testosterone-to-estrogen ratio in a more youthful range
- Boost energy and sex drive
- Improve recovery after training
- Enhance sleep and mood
The 3 supplements below have been road tested for months and are completely clear of any chemicals or synthetic ingredients. Our criteria included product safety, optimal ingredient doses, short-term benefits, long-term benefits, company reputation and a lot more.
We really don’t like crap products at Ookles. And trust us when we say there are some seriously crap products out there. Thankfully, after testing the 35 most popular testosterone boosters this year, we’ve narrowed it down to these 3 legitimate contenders.
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 your 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 most certainly get back to your youthful peak.
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 boost your low hormone levels. While testosterone boosters are not a miracle pill, they can definitely 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:
- 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.
- Zinc – an essential mineral that influences hormones, sleep, and mood among others. Over 2 billion people may be deficient according to studies. They also show that zinc supplementation helps to prevent dips in testosterone levels, along with boosting your libido.
- 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.
- 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]
- Indole-3-Carbinol – or simply I3C, it 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.

We didn’t just get awesome results using it, but also very fast delivery and an extra free bottle with our first order. You also get a free nutrition and workout guide (worth $14.99) with the 3-month package. We didn’t use the guide but it looked well-crafted.

TestoFuel’s Official Website: https://www.testofuel.com/
Testofuel has been a market leader for so many years in the past, 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 in reality, these studies are weak and often performed on rats.
TestoFuel also makes serious claims, but it backs them up with real science. The best ingredients in TestoFuel include:
- Oyster extract (100mg)
- Magnesium Aspartate (200mg)
- Vitamin D (4000IU)
- D-Aspartic Acid (2300mg)
- Asian Panax Ginseng (100mg)
TestoFuel uses Oyster extract as a convenient way of getting the nutritional goodness of oysters, including a naturally high amount of zinc that boosts 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 boost testosterone levels by over 30% in less than a month, although the effects do wear off over time.

Our TestoFuel order was a bit pricey, but we got it quickly and were impressed with the ingredients that it offered. At first it was a little frustrating trying to remember to take 4 capsules each day, but we quickly got into the swing of it. The libido and performance increase was real… and what was surprising was the reduction in belly fat after about a month of using it.
What do Others Say?
