The [5] Best Testosterone Booster Supplements | Ultimate Men’s Guide

The key male hormone responsible for giving a man his ‘manly’ attributes – testosterone – is a much talked about topic among both men and women alike. In fact, for decades, athletes, weightlifters, fighters, Olympic competitors and casual gym-goers alike have tried ways to boost the key hormone which not only allows them to push the physical performance envelop but also stay young and enjoy a healthy life.

Many tout that they are the best testosterone booster out there, claiming to boost the male hormone by xx percentage.

How Testosterone Boosters Work

Testosterone boosters contain naturally occurring vitamins, minerals and herbs – the first two our bodies produce naturally – while the herbs contained within t-boosters such as Green Tea, Trigonella foenum-graecum (Fenugreek), Panax ginseng and Ashwagandha help the body unlock more of its natural and free testosterone. 

Many people tend to confuse testosterone pills and testosterone boosters with steroids. This isn’t quite true and something we’ll be shedding light on later in the article. 

The way test boosters work is that they encourage the luteinizing hormone (LH) in the brain to signal the testes to produce more testosterone. LH is the main hormone in the brain that gives your body the “go ahead” to produce testosterone. 

T-boosters stimulate LH levels naturally through a combination of minerals and vitamins like zinc, vitamin D, D-aspartic acid and more, as well as certain herbal blends which all work synergistically to unlock free testosterone levels. So, essentially what you’re doing is simply unleashing your genetic potential for producing optimal testosterone levels. We could go out on a limb here to get really technical – however, these basics tend to cover everything you need to know about how test boosters work. 

Are there any Side Effects? 

Naturally, when you’re going to invest in something you’ve never tried before – especially where your health is involved – you may be leery at first and immediately have concerns about testosterone booster side effects.  

While steroids do work to give you the desired results, they can often wreak havoc on your health, including shutting down your natural testosterone production permanently! This is where a natural testosterone booster comes in as a safe and effective alternative – they contain natural ingredients which simply encourage the body to produce optimal testosterone levels, with the only limiting factor being your genetics. 

The 5 T-boosters listed in this article have been tested to be completely safe and have offered users a variety of health benefits including more strength, endurance and muscle mass, reduced body fat, improved sexual performance, better sleep, optimal mood throughout the day and more. Testosterone boosters are a fantastic way to get the results you’re after with no side effects, although you will have to put in a fair amount of hard work if getting strong or back into shape is your key goal. 

Best Ingredients to look for in a Testosterone Booster

When searching for the best testosterone booster, it’s important to buy one which contains all the right ingredients in order to boost your free and natural testosterone levels. You’ll typically find many parallels in different test boosters when it comes to ingredients. Here are some of the ingredients you’ll find in a really good natural testosterone booster:

D-Aspartic Acid

D-aspartic acid increases the brain’s ability to release a hormone – specifically, follicle-stimulating hormone and luteinizing hormone – which ultimately encourages the testes to produce more testosterone. 

Fenugreek

There’s plenty of research to indicate Fenugreek’s ability to naturally increase testosterone, thanks to the compounds it contains known as furostanolic saponins. In one study, in fact, it was discovered that natural testosterone levels increased by 46% in 90% of the participants. 

Vitamins B5, B6, D and K

Vitamin B5, also known as pantothenic acid, is one of 8 B vitamins, and helps your body convert fat, protein and carbohydrates into energy. B vitamins, including B5, are needed in the production of sex hormones in the adrenal glands, so it’s easy to see why your natural testosterone booster would have this ingredient.  

You may have noticed how vitamin B6 is present in a variety of test boosters and even ZMA formulas (the ZMA stands for zinc, magnesium, B6), as it helps the body recover and feel more primed to face the stresses of the day. 

A t-booster containing vitamin D can boost testosterone and even sperm quality. One study established a link between low testosterone and vitamin D deficiency – with participants having higher levels of testosterone when they spent more time in the sun.  

There’s also plenty of research on vitamin K’s efficacy for maintaining healthy testosterone levels. 

Zinc

Zinc has been widely known to be one of the most effective minerals for boosting testosterone levels naturally. Even 30mg of zinc per day has been shown to increase free levels of testosterone. 

Boron

Boron is so effective at boosting testosterone levels that it is not only present in the vast majority of test boosters but also given to those suffering from erectile dysfunction. 

Magnesium

Supplementation with magnesium can aid in returning testosterone levels to normal, particularly for those suffering from low levels, such as men over 40 and 50. ZMA is a very popular supplement and often included in test boosters, known for its ability to help men recover better from exercise and other physical stresses, and improve quality of sleep – magnesium is a key ingredient. 

Different varieties of ginseng

Ginseng has been known to fight off fatigue and exhaustion, and increase energy levels naturally. It is often prescribed as a treatment for erectile dysfunction as well. All varieties of ginseng are typically found in test boosting supplements as they influence the two key sex hormone receptors in the body: estrogen and androgen, helping men optimise their testosterone levels. 

Bioperine 

Bioperine, one of the key ingredients in black pepper, contains a range of naturally-occurring chemicals known as alkaloids. These are directly responsible for many therapeutic benefits, including anti-inflammatory properties, normalised blood pressure, better liver function and reduced insulin resistance. All of these lead to healthier testosterone levels, particularly in ageing men. 

Garlic extract

Garlic plays a proliferative role in boosting testosterone levels. In fact, foods like garlic and onions are men’s allies not just in the gym but in the bedroom as well. It raises levels of a specific hormone in the body which triggers it to produce more testosterone.

Nettle leaf

This powerful plant can prevent the conversion of free and available testosterone into dihydrotestosterone – a more potent and powerful form of the key male hormone. Nettle leaf helps stop this conversion, resulting in more available free testosterone to help you build muscle and maintain an optimal sex drive. 

Pomegranate

Pomegranates have been considered for a long time as being the top most sought after foods for boosting testosterone levels. Any test booster containing pomegranate extract will inevitably boost testosterone.

Catechins

It’s widely known in the scientific world that green tea can increase sperm concentration and have a positive effect on testosterone production, due to a key compound it contains: catechins. This also helps the body make use of the available testosterone more readily.    

While these ingredients are a sure sign that your test booster will work, it’s important to remember that testosterone pills are not ‘magic pills’ – you shouldn’t expect them to work by just popping a few pills and leading a sedentary lifestyle coupled with processed food. An active lifestyle, balanced diet and keeping stress levels in check along with adequate rest, all ensure that your T-booster will work as intended. 

Signs of Low Testosterone

If you or anyone you know is experiencing any of these symptoms, then you may have low testosterone:

Higher bodyfat with less lean muscle mass

Even if you are working out and watching what you eat and still have stubborn bodyfat around the waist, for example, then you probably have low testosterone level. With age, the testosterone to estrogen ratio changes, with many men having higher cortisol levels due to stress, which can increase estrogen levels – hence, leading to higher a bodyfat percentage and a condition called gynecomastia in some men, or ‘male breasts’. Moreover, it can be very difficult to maintain muscle, let alone put on more muscle. 

Frequent mood swings

Men with low testosterone levels experience sudden changes in mood and/or more frequent mood swings due to andropause – the male equivalent of menopause, which cause mood swings in women. Brain fog, difficulty focusing and getting irritated easily are some of the symptoms, in addition to the sudden changes in mood. 

Reduced sex drive

With low testosterone levels, the brain does not have the capacity to signal the body to send more nitric oxide and blood to the reproductive organs, which is otherwise needed for strong and sustainable erections. Difficulties maintaining an erection or getting aroused may signal a testosterone deficiency.  That’s why most Testosterone Boosters can be used as natural ed pills too!

Issues sleeping

Since low testosterone can cause irritability and frequent mood changes, it can also cause insomnia and sleep disruptions. 

Excessive fatigue 

Testosterone is one of the key hormones which allows the male body to wake up from restful sleep, and feel refreshed as well as rejuvenated. When the brain no longer signals the testes to produce enough testosterone, it can raise cortisol levels and also lead to a constant feeling of tiredness and fatigue. 

Pros and Cons of using Testosterone Boosters

There are many benefits of taking testosterone pills or a natural testosterone booster. These include:

Higher bone mass

Dwindling testosterone levels can have an adverse impact on bone mass, while increasing it does the opposite. Men with higher testosterone levels can stay safe from conditions like osteoporosis and arthritis, which is why many male athletes take a testosterone booster to protect themselves from injury. 

Better blood flow

Higher levels of testosterone mean more red blood cell production, and this is needed for muscle tissue to stay healthy. Optimal testosterone levels improve the cardiovascular system by improving oxygen-rich blood flow to the muscles. 

Improved sex drive

Men who have a low sex drive or find it difficult maintaining an erection have reported very positive feedback after using a test booster, in addition to having more stamina and vigour during sex. 

Mood enhancement 

Optimal testosterone levels in men of all ages are related to feeling energetic, motivated and positive. Many studies have shown the positive effects of testosterone boosters on the mood, as well as emotional and mental wellbeing. 

While minimal to no negative impacts have been reported as a result of using a natural testosterone booster, a few potential cons are worth noting:

  • Testosterone boosters work differently on everyone. If person A starts to see results within, say, 2 weeks or so, person B may not see those results within a similar timeframe – owing to a number of factors such as diet, lifestyle, genetics, etc. 
  • Not every test boosting product is made equal. Some take months to work while some yield results within weeks. 
  • T-boosters are not meant to replace healthy lifestyle and diet practices which also help to maintain healthy testosterone levels. 
  • They can be potentially unsafe if you try to overdose or exceed the manufacturer’s recommended dosage in an attempt to increase testosterone levels faster. 
  • Some test boosters can only be bought online, while others are exclusively available directly from the manufacturer only, and not third-party e-stores. 

What to look for when buying the Best Natural Testosterone Booster?

Choosing the right testosterone booster means looking at certain factors, which helps to ensure that you’re reaping the most benefits. 

The following are just some factors you should be considering when looking for the best testosterone booster for men over 40 or 50:

The price

When it comes to the price of testosterone boosters, you need to exercise caution. While the goal is to buy a quality product at a reasonable price, a really cheap ‘too good to be true’ price most likely means the product has not passed quality testing and may not even have the ingredients it claims on the label.

It must be understood (and appreciated) that a quality test booster will always come at a price. The ones we’ve reviewed in this piece, for example, offer the best of both worlds – great quality and a reasonable price to deliver the results as expected.

Potential side effects

Research on the potential side effects of testosterone boosters isn’t as extensive as it has been on other kinds of supplements. With that said, the inherent risk of unwanted side effects tends to be present in low-quality products. 

Some over-the-counter shops may be selling expired or contaminated products, or even fake ones. Always buy from a trustworthy source and don’t hesitate to ask the seller to discuss any potential side effects with you. 

For this reason, we’ve handpicked the above brands as there are no known side effects of using them.

Check the label 

When shopping for the best testosterone booster for men over 50 or testosterone pills, always check to see what kind of ingredients it contains and in what quantities. 

The ingredients we’ve listed at the beginning of the article, for instance, should be present in a test boosting supplement as they are natural, effective and completely safe to consume. 

Still, if you have any underlying health conditions or have suffered any health issues whatsoever in the past as a result of using test boosters, ask your physician to have a look at the label and give you the green light before you buy. 

Overall quality and effectiveness

When you’re buying online from a reputable source, it’s easy to distinguish a quality product from a substandard one. 

Reviews and referrals on Amazon are one way to determine the quality and efficacy of a testosterone supplement. The brands we’ve listed in this piece have all received shining reviews from users all over the world and are a hallmark of quality and effectiveness when consumed in the recommended dose. 

Legal and safe

The last thing you absolutely want when buying a natural testosterone booster is a product that’s not legal and leaves you with side effects.

An all-natural testosterone booster should always be free of artificial ingredients and/or banned substances, such as the ones in this article. 

If you’re suffering from any conditions such as high blood pressure, diabetes or chronic fatigue, we’d recommend checking with your doctor before using a t-booster. 

The brand’s reputation

Even though discussed briefly in one of the points above, we can’t stress on how important it is to ensure that you’re buying from a brand that’s known for quality. 

Always buy directly from the brand’s website to ensure that you’re buying the genuine stuff or from a trusted vendor such as Amazon. 

Frequently Asked Questions about Testosterone Boosters

How safe are testosterone boosters, really?

You may come across mixed opinions regarding how safe t boosters are. Here’s the thing: synthetic test boosters may contain harmful preservatives which can not only lead to unwanted side effects but potentially increase the risk of developing certain health conditions. 

On the other hand, the benefits of using an all-natural testosterone booster such as the ones we’ve handpicked, is that they are 100% legal and safe to use, with no side effects. 

Aren’t testosterone boosters in the same category as steroids?

Not at all. Natural testosterone boosters made under strict quality standards using natural ingredients only encourage the body to ramp up testosterone production in a natural way – i.e. according to what it is genetically capable of. 

Some men, for instance, have too much estrogen in their body, and a natural test booster can help them balance the testosterone-estrogen ratio to increase muscle mass, among other things. However, synthetic test boosters or drugs that produce abnormal levels of testosterone by shutting down the body’s own testosterone production, are definitely “steroids” that you should avoid at all costs. 

Testosterone boosters – Are they for everybody?

With people constantly increasing their knowledge around what their bodies are capable of, we are thankfully, once again returning to nature. 

Synthetic products are harmful, period. This is why most fitness enthusiasts, athletes and weekend warriors alike turn to natural test boosters to promote strength, muscle mass, and endurance, and recover faster from intense physical activity. 

Thanks to our knowledge around the subject, we can confidently suggest the above products as those anyone can take – as long as they are not suffering from any serious health conditions already. All natural ingredients means that you’re encouraging the body to produce more of the key male hormone, and not experience any side effects as long as you stick to the recommended dose. 

In Closing: Are Testosterone Boosters ‘Steroids’? Are they safe?

Just to reiterate: test boosters are most definitely not steroids. They are completely legal and safe to consume. The brands we’ve listed above all offer unique attributes in terms of boosting testosterone. 

If you have any concerns whatsoever about raising testosterone levels naturally through a supplement, do consult your doctor.
