Were you at all aware that testosterone levels tend to drop after the age of 30? Precisely, with every one-year increase in age thereafter, testosterone levels are likely to drop by one percent. Sure, one percent may not seem like a lot right now, but as time progresses, the consequences only worsen, creating a snowball effect that is nearly irreversible. Imagine how distressing this would be for men who are already battling with inconsistencies in their levels! Fortunately, society is at a place where solutions are regularly introduced to the general public. One such solution is something called a testosterone booster.
As suggested in its name, testosterone boosters are additional supports that increase testosterone levels. These are often manufactured as dietary supplements to be taken with healthy practices. Okay, fine, it isn’t something that works overnight, but many men have since reported healthy T-levels and other improvements in wellness as a whole. Given the widespread availability of testosterone boosters, this present guide has been prepared as a resource for men who are eager to raise their levels and wanting to enjoy their lives like they once used to.
Before diving right into this matter, our team feels it is most beneficial to provide an overview of testosterone. Not everyone is fully aware of how important this hormone is and the types of symptoms that can be faced when proper care isn’t sought for. Hence, the importance of covering the basics. Without further ado, here’s the ABCs of testosterone:
A Brief Overview: T Stands for “Testosterone”
Testosterone, mostly referred to as a male hormone, is a sex hormone that is produced in the bodies of men and women. In terms of a male body, this hormone is usually produced and located in the testes, adrenal, and pituitary glands and above the kidneys. Between the two genders, men are the ones to rely on it, seeing that the hormone gives rise to growth spurts, deepening of the voice, muscular build, sperm count and quality, sexual drive, body hair, and red blood cell production. In fact, health indicators such as metabolic rate, fat storage, cardiovascular health, and strength also depend on it [1].
Unfortunately, in some men, testosterone production gradually decreases with age. The scientific term for lack of production is male hypogonadism, which leads to low testosterone. Though age is almost always the culprit, other factors may include dysfunctional testes, poorly functioning pituitary glands (i.e., responsible for maintaining testosterone), genetic issues, medications, obesity, hormonal conditions, and injuries. As a result, men might face decreased sex drive, poor erection, reduced semen volume, quality, poor muscle build, weak bones, and the list only seems to grow from here [2].
Clearly, this hormone should not be overlooked, as it defines a man’s overall quality of life. Since our goal is to simply shed light on the significance of testosterone, we did not dive too deep into matters. That said, we do encourage everyone to fully grasp the biological aspects of this hormone for a more wholesome appreciation and, above all, optimal health. With this foundational knowledge, we can now introduce the testosterone boosters that met our ranking criteria.
Testosterone Boosters That Made the Cut
After thoroughly researching the market for testosterone boosters and the recommendations made by experts, the scientific community, and traditional medicine, our team narrowed down the list to 11 top testosterone boosters for male enhancement purposes. In no particular order, they include:
- Barbarian XL by Zenith Labs
- Testo-Max by CrazyBulk
- Hunter Test
- JayLab Pro T20
- Prime Male
- Testo 911 by PhytAge Labs
- TestoFuel
- Testogen
- TestoPrime
- TestoLab Pro T-Booster
- TestRX
Barbarian XL by Zenith Labs
Manufactured by Zenith Labs, Barbarian XL is a cutting-edge formula that combines five all-natural ingredients (i.e., Boswellia Resin Extract, Ashwagandha, Tongkat Ali, Shilajit, and Korean Red Ginseng) that work synergistically to help the body maintain sexual vigor, energy levels, and one’s overall confidence. These are supposedly resulting from the formula’s potential to promote healthy levels of testosterone.
A reassuring factor, in this case, is that Barbarian XL was formulated by a naturopathic doctor and chief medical officer of Zenith Labs, Dr. Ryan Shelton. As someone who embodies natural treatments while also respecting science, Dr. Shelton trusts that this formula can do wonders. In cases where it fails to induce desirable results, each Barbarian XL has since been protected by a 180-day money-back guarantee. Luckily, for those who are interested, the Zenith Labs team provides a complete breakdown of their ingredient list on the official website. Price: $49 Learn more about Barbarian XL here.
Testo-Max by CrazyBulk
CrazyBulk is a supplements manufacturer that aims to introduce natural and legal alternatives to steroids in the market. Their take on a testosterone booster is called Testo-Max and is deemed an alternative for Sustanon. Sustanon (Su) is described as an oil-based injectable anabolic-androgenic steroid that has been liked for the purposes of continuously releasing testosterone into the blood for periods ranging anywhere between three and four weeks [3]. The drawback that stems from taking Su can easily range from nausea and acne to changes in cholesterol levels and liver function or, worse, heart failure.
To avoid complications from taking Su, CrazyBulk Testo-Max seems like the more reasonable bet as it includes ingredients such as D-Aspartic Acid, Nettle Leaf Extract, Ginseng Red Powder, and Fenugreek, among others. Together such ingredients may promote extreme strength, enhance performance, and reduce recovery time. Matter-of-factly, this solution is deemed suitable for men who have to alternate between bulking and cutting cycles.
All things considered, what we appreciate about CrazyBulk is their thorough explanations, level of transparency, the advice that the team provides based on unique health goals, and of course, their 60-day money-back guarantee. Price: $79.99 Learn more about CrazyBulk TestoMax here.
Hunter Test
Hunter Test or “Test” by Hunter is advertised as a premium testosterone booster that enhances strength and health, maximizes mental strength, is likely to reverse testosterone decline, and may “reignite” one’s masculinity. The team behind this solution pride themselves in offering a formula with higher doses for a powerful boost, natural ingredients that have been backed by scientific research, quality and purity assurance, and one that can be thought of as a complete package, especially for those who are into fitness or training of any sort.
Speaking of ingredients, this solution contains Vitamin D3 and D-Aspartic Acid, both of which are trusted to boost test levels by 20% within a year while also increasing sperm counts by a whopping 100%. As seen on the supplement facts, other ingredients include Ashwagandha, Boron Chelate, Zinc, and Magnesium, to name a few. In terms of their refund policies, orders placed within the U.S., Canada, or Mexico are offered a 30-day money-back guarantee, while the rest of the world is offered a 14-day money-back guarantee. It seems like this company is a bit stricter on refunds; hence, we do encourage everyone to discuss these matters with customer service beforehand.
Nevertheless, like the above two companies, Hunter is also very elaborative and transparent in how information is delivered. In addition, the team has taken extra measures to ensure that men are well-informed on what they are signing up for prior to placing an order. Price: $75 Learn more about Hunter Test here.
T20 by JayLab Pro
JayLab Pro T20 is a testosterone booster that not only increases testosterone but may also go as far as enhancing healthy circulation, increasing libido, energy levels, and endurance, slimming down waist and stomach, promoting cardiovascular wellness, and minimizing everyday aches to name the least. Another supplement founded on the minimalistic approach, T20, combines the effects of Tongkat Ali, L-Norvaline, Avena Sativa, Cordyceps Sinensis, Rhodiola Rosea, and Tribulus Terrestris on testosterone and male enhancement as a whole. The fact that it is founded by a registered dietitian and certified strength and conditioning specialist, Jayson Hunter, makes this solution all the more legitimate and likely a comforting aspect for consumers.
Moreover, this company is devoted to shedding light on the importance of choosing supplements that are backed by science, simplicity, effectiveness, and safety. Again, these are reassuring factors, especially for men who have been hesitant about the natural approach to things. Aside from transparency, which this company clearly does not fall short on, JayLab Pro does offer a 60-day money-back guarantee as well. Price: $74.95 Learn more about JayLab Pro T20 here.
Prime Male™
Prime Male is a natural testosterone booster that is proclaimed as housing 12 critical nutrients that more or less guarantees hard-driving, healthy, fit, and energetic men. The team behind this solution insists that they found the right balance between low and excess doses per serving. For this reason, their solution is believed to induce results without any of the unwanted side effects while underscoring healthy lifestyle choices. In fact, Prime Male™ is deemed so potent that “maximum effect [can be felt] in minimum time” or precisely, it can “boost testosterone [by] 42% in 12 days.”
As for how it is meant to work, the team highlighted how factors including the luteinizing hormone (LH), sex hormone building globulin (SHBG), and female sex hormones such as estrogen and prolactin are part of the issue. To deal with the presence of such hindrances, ingredients like D-Aspartic Acid, Vitamins D3 and B6, Ashwagandha, Nettle Root Extract, and Asian Red Ginseng have been considered. As a final remark, Prime Male™ has been protected by a money-back guarantee, but it is not as long as the rest, i.e., a 7-day money-back guarantee. Price: $69 Learn more about Prime Male here.
Testo 911 by PhytAge Labs
Testo 911 is PhytAge Labs’ take on a natural testosterone booster. Combining the effects of 9 ingredients, the team strongly believes that their research has led them to formulate a solution that might increase energy levels, induce bodily wellness, provide long-term muscle support and strengthen one’s overall immune health. The main ingredients that appear to have made the cut in this formula include Vitamin B6, Magnesium, Zinc, Fenugreek, Rhodiola Rosea, 3,3’-Diindolylmethane, Eurycoma Longifolia, Piperine, and Piper Nigrum Extract.
Given that this company has managed to bring together nutritional experts who have a history of developing professional-grade health solutions, we had to include it in our list. While their level of delivering information is not as complete as the latter companies, factors including transparency, concentrations per dose, and accessibility to the customer service team, among others, were encouraging to see. In addition, they offer a 90-day money-back guarantee, which is longer than what most companies tend to offer on average. Price: $69.95 Learn more about Testo 911 here.
TestoFuel
TestoFuel is an anabolic support complex that has been formulated to bring together nutrients proven to elicit testosterone release in the body. In so doing, the team affirms that men can expect to witness more growth, bigger muscles, increased energy levels, and faster and healthier recovery. In regard to the formula itself, the selected ingredients, which include D-Aspartic Acid, Vitamins D, K2 and B6, Oyster Extract, Ginseng, Fenugreek, Magnesium, and Zinc, are said to have been carefully selected and tested for purity, quality, and effectiveness.
Interestingly, the main principle that this formula is founded on is none other than “compound nutrition.” As explained by the TestoFuel team, this formula works similarly to working out in a gym. Isolation exercises are unlikely to pack on muscles compared to compounded exercises. The latter is what builds and shapes both our larger and smaller muscles. Hence, TestoFuel is believed to combine ingredients in a similar way that targets testosterone and its related effects for complete results.
What we liked a lot about the TestoFuel team is their knowledge and the efforts that they continue to take to educate men, leading them towards healthier lifestyle choices. Finally, in regard to the refund policy, TestoFuel has been backed by a 30-day money-back guarantee for U.S. and Canadian orders and a 14-day money-back guarantee for the rest of the world. Price: $65 Learn more about TestoFuel here.
Testogen
Testogen is a testosterone booster that places emphasis on not only total testosterone but also free testosterone levels. This formula supposedly reflects the coming together of science and nature, where the duo can enhance male health, all while blocking hindrances such as female sex hormones.
As for how it is meant to work, when the luteinizing hormone is lower in counts, men are likely to experience falling testosterone rates. For this reason, the team responsible for Testogen insists that increasing the production of this particular hormone will stimulate Leydig cells in the testes essential for producing and releasing testosterone. Next, this formula is believed to increase free testosterone in the body. Earlier, we mentioned that most testosterones are bound to SHBG. Well, this prevents them from being usable. Hence, the need for free counterparts. Finally, ingredients have been selected to prevent the conversion of testosterone to female sex hormones, which is clearly self-explanatory.
Given the above goals that Testogen aims to achieve, we investigated the ingredients and discovered that the main one is D-Aspartic Acid, followed by Fenugreek Extract, Zinc, Vitamin D3, Korean Red Ginseng Extract, Boron, Nettle Leaf Extract, Magnesium, Vitamins B6, and K1, and Bioperine. Finally, this supplement has also been protected by a fairly nice refund policy, i.e., individuals will need to reach customer service within 100 days of receiving their order for guaranteed refunds. Price: $59.99 Learn more about Testogen here.
TestoPrime
TestoPrime is an all-natural testosterone support that is believed to increase physical and mental energy, support protein synthesis, burn unwanted fat and increase one’s overall confidence level and mood. With 12 ingredients per serving, this formula has the potential to increase testosterone production and induce healthy muscle building in the process. In addition, the team claims to have considered means of controlling external factors such as stress response, lack of oxygen, and fat storage, among others.
In fact, TestoPrime’s ability to regain control over factors that trigger low testosterone is all thanks to the likes of D-Aspartic Acid, Panax Ginseng, Ashwagandha, Fenugreek, Green Tea Extract, Pomegranate Extract, Vitamins D, B5 and B6, Zinc, Garlic Extract, and Black Pepper Extract. What definitely caught our attention are the concentrations per serving, which, compared to all of the supplements listed in this piece, are much higher. To add to that, each TestoPrime has been protected by a lifetime money-back guarantee, and this reflects how confident the team is in their solution and its overall risk-free nature (at least financially). Price: $59.99 Learn more about TestoPrime here.
TestoLab Pro T-Booster
Testo Lab Pro T-Booster has been formulated with the intention of creating synergy between exercise and testosterone production. Having included six research-backed testosterone boosters and performance enhancers (i.e., KSM-66®, D-Aspartic Acid, Mucuna Pruriens Extract, Luteolin, and patented vitamins and minerals blend, NutriGenesis®), this formula has been since been advertised as one that is safe, clean, legal, and effective, and both third-party tested and validated. For men who are presently vegan, the capsules found within each bottle are premium and plant-based, which is a nice asset.
We are clearly repeating ourselves when we stress how transparent, informative and accessible all of these products are and the same definitely applies to T-Booster. Every possible question and/or concern pertaining to testosterone boosters has been covered by the team. In all truth, they continue to encourage everyone to reach out to the customer service team to learn more! As for its refund policy, T-Booster has been protected by a 30-day money-back guarantee. Price: $69 Learn more about TestoLab Pro T-Booster here.
TestRX
TestRX is a natural testosterone supplement that supposedly increases muscle mass, energy, strength, and sexual drive. In addition, it is trusted to achieve weight loss. In terms of how such results are attainable, the team has given credit to the likes of ZMA (monomethionine and aspartate), Magnesium Aspartate, and Vitamin B6. Each of these ingredients is believed to induce protein synthesis, which gives rise to muscle growth. Not only that, but this supplement also aims to promote the importance of diet and exercise, two major factors that can either make or break one’s testosterone production.
Who can forget this formula has the potential to induce sleep and maximize nutrients delivery essential for testosterones!? Finally, based on the claims made, TestRX should be able to limit men’s catabolic hormone, also known as cortisol, as the increased levels of the latter have been linked to decreased testosterone levels. Finally, for those of you who are interested in giving TestRX a try without any of the financial risks, it comes with a 60-day money-back guarantee. Price: $69.99 Learn more about TestRX here.
A Detailed Look at the Ranking Criteria
By now, it should be evident that many of the listed supplements have similar traits. Well, that’s because we stuck by our ranking criteria prior to scavenging for testosterone boosters. Bear in mind that the following factors are based on extensive research and experts’ input on the matters. The purpose of ranking criteria is to give everyone a general sense as to how one can identify a good supplement over the weaker types. Said list is certain to vary depending on one’s respective beliefs, preferences, and expectations. Nonetheless, here’s ours:
1. Ingredients
The number one factor that should be assessed prior to buying a testosterone booster is the ingredients list, namely, the research evidence that the ingredients have in relation to boosting testosterone levels and its related symptoms. In an attempt to understand some of the key ingredients that said supplements generally contain, we discovered a study that aimed to evaluate the highest-rated and frequently reviewed testosterone boosters. In the process, the researchers did an ingredients analysis, only to find that there are 10 common types.
The ten include Tongkat Ali Extract (3 human studies), Horny Goat Weed (0 human studies), Saw Palmetto Extract (10 human studies), Boron (9 human studies), Nettle Extract (1 human studies), Maca Root Extract (4 human studies), Ashwagandha Root Extract (1 human study), Fenugreek (7 human studies), Bioperine (1 human study) and DIIM (1 human study). While it isn’t as encouraging to see that most models are based on animal subjects, results are often generalizable to humans (at least to a certain level) [4]. Others that have reoccurred in our search include Vitamin D3, D-Aspartic Acid, and Magnesium.
2. Concentrations
The per-serving ingredients’ concentrations need to be thoroughly evaluated to have a general idea as to whether the suggested prices are reasonable and if the solution itself is truly effective. If the concentrations are too low, results will be prolonged, while anything in excess might worsen the situation. Therefore, a balance between the two extremes needs to be measured for men to experience heightened testosterone levels. In most studies, researchers tested anywhere between 100 and 1000mg for herbs and plants and smaller concentrations for vitamins and minerals. Thus, this was the only logical step to take for the purposes of this guide.
3. Company Background
Company background is a simple yet meaningful factor that allows individuals to either connect or stray away from a solution. If a testosterone booster is advertised without any mention of the manufacturing company, mission statement, values, and/or contact information, its overall legitimacy will be heavily questioned. Knowing what a company stands for and why it is that they are in a particular business gives individuals hope that the right processes have been taken to guarantee safety, purity, quality, and effectiveness.
4. Transparency
Transparency and company background go hand in hand. The more information available, the more comfortable and confident consumers become before placing an order. We made sure to find companies that were completely transparent in what they were offering. Some indicators of this include making the supplement’s fact available, providing a thorough frequently asked questions section, explaining briefly the thought process that went behind picking the ingredients, quality control, and above all, contact information.
If there’s no way of connecting with the creators of a particular solution or if the support team takes far too long, say well over 72 hours, to respond to emails or phone calls, it might be safest to seek an alternative solution. Contacting the support team is important because their responses can either dictate care and eagerness to help or a lack thereof, making it easier to rule out companies of disinterest.
5. Features
In general, knowing that a supplement carries a wide range of features excites consumers because it might feel as though they received a solution that is worth every penny spent. However, features are a great way to read between the lines, especially when it comes to the manufacturer’s knowledge of testosterone.
One major feature that everyone should look out for is whether the supplement contains soy products. Why? Well, soy products have been linked to increased levels of estrogen and, therefore, low testosterone. Another feature that we were adamant to see is the use of natural and legal ingredients. In the past, steroids were highly encouraged, but evidently, times have changed, and steroids are now becoming of less importance.
Other features that were of interest include the country in which manufacturing processes took place (i.e., for the purposes of regulations), testing and validations (i.e., for the purposes of quality and safety), and ease of ingestion (i.e., it needs to be easily incorporated on a daily basis).
6. Return Policies
In most cases, companies like to reward consumers who purchase in bulk by offering them a significantly reduced per-unit cost. For example, one bottle might cost $69; however, when three bottles are purchased at once, the per-unit cost might be anywhere between $49 and $59. The latter obviously depends on the company but having access to savings opportunities is always motivating. That said, not all testosterone boosters will work for everyone. Matter-of-factly, results might be more apparent in some cases than in others.
Ultimately, refund policies give consumers the chance to try a solution risk-free. If, after a month or two, results are unnoticeable and there still remain unopened bottles, they can be returned as long as customer service is contacted within the allotted period. Sure, many companies do charge restocking fees and rarely cover the shipping costs linked to returns, but some portion will be credited.
7. Advertised Benefits
Regardless of the industry in which individuals are looking to make a purchase, the first thing one is likely to search for is the listed benefits and how they compare to verified experiences. By advertised benefits, we mean the results that stem from taking said supplements, whether they are realistic or overly exaggerated, and to what level the benefits are linked to testosterone boosters. For example, any advertisement that insists on results within a couple of days to a week or two has been excluded from our picks because they are rare.
To add to this, if the manufacturer affirms that there’s no way for side effects to occur, then we decided to omit them. Just because all-natural ingredients are thought to be safe, it does not mean that they cannot induce side effects. Companies that actively advise consumers to consult a physician beforehand are the ones that we were fond of.
8. Price
Although price should be one of the last factors to reflect upon, it remains one of the firsts that consumers are attracted to. There will be cases where individuals may approve of all of the aforementioned factors, but because the price is either high or well outside of their budget, they might just end up changing their minds. Men in dire need of a testosterone booster and are willing to put the effort towards positive change should not be turned away. Hence, we decided to limit the prices between USD$49 and USD$80.
What Science Suggests About Testosterone Boosters
Our main focus in regard to how the scientific community perceives testosterone boosters rests in the included ingredients. Honestly, there are just so many ingredients that might have an effect on testosterone production; hence, to further simplify things, our top 11 testosterone boosters were compared amongst each other to see which ingredients were reoccurring. In so doing, we narrowed the list down to eight ingredients that warrant investigation.
Here is an analysis on the top reoccurring eight:
Ashwagandha
Ashwagandha is an Ayurvedic herb that acts as an adaptogen to support the body’s ability to better manage stress. Upon researching the herb’s benefits in male health, one study that looked at the herb’s effect on fatigue, vigor, and steroid hormones in overweight men aged 40 to 70 caught our attention.
Conducted over a span of 8 weeks, this randomized, double-blinded, placebo-controlled, crossover study indicated that ashwagandha intake was linked to an 18% greater increase in DHEA-S and 14.7% greater increase in testosterone. However, when it came to factors such as cortisol, fatigue, vigor, or sexual well-being, there was no difference between the control and placebo groups [5].
Another study reported by one source also arrived at a similar conclusion. In this study, 46 men were given a patented form of ashwagandha called KSM-66™. This led to a 17% increase in testosterone levels within 90 days. Moreover, the full spectrum uses of ashwagandha led to an increase in sperm count (167%), semen volume (53%), and sperm mobility (57%). Matter-of-factly, Health Canada affirms that this ingredient can support healthy testosterone production in men. Here are a couple of words from the director of Ixoreal Biomed (i.e., creator of KSM-66™), Kartikeya Baldwa:
“The effect of ashwagandha on testosterone production is similarly integrative and organic. We should not expect KSM-66 to produce substantial testosterone increases in males with already very high testosterone levels […] because such increases would be counter to the natural state of balance in such individuals [6]”.
Finally, we have a study that was curious to see whether ashwagandha intake contributes to muscle strength and mass. This randomized, double-blinded, placebo-controlled clinical study consisting of 57 men found that compared to the placebo subjects, the control group experienced greater increases in muscle on both the bench-press and leg-extension exercises. In addition, their arms and chest are said to have increased in size, while the risk of injury significantly dropped [7].
Korean Red Ginseng
Korean Red Ginseng (or commonly referred to as Asian Ginseng) is a plant that has been used as a treatment to enhance the immune system. As per one source that reported on the plant’s proven traits, it was shared that its ginsenoside compounds can prevent inflammation and increase antioxidant capacity in cells. In terms of male health, close to eight studies were reported on its ability to treat erectile dysfunction.
For instance, one study that treated men with Korean Red Ginseng supposedly had a 60% improvement in erectile dysfunction-related symptoms compared to a 30% improvement found within the group that was given conventional medicine [8]. Another study with a similar goal and a larger sample size (n = 86) found improvements in erectile dysfunction and overall satisfaction. This was linked to a dose of 1000mg of aged ginseng extract, which was ingested over the course of 8 weeks [8].
One review that looked at the effects of ginseng on male reproductive function highlighted a number of animal studies that have proven its effects. Namely, they wrote that there is a positive correlation among ginseng, libido, and copulatory practices, adding that “these effects have been confirmed in case-control studies in humans” as well.
Other areas of improvement include sperm quality and count of healthy individuals and patients with treatment-related infertility. As previously mentioned, these benefits have all been linked to the plant’s rich source of ginsenoside compounds [9].
D-Aspartic Acid
D-Aspartic Acid is a type of amino acid that is involved in the production and releasing of testosterone throughout the body. One review with the aim of summarizing available evidence on the effects of D-Aspartic Acid on serum testosterone levels concluded that in their analysis of 23 animal studies and 4 human studies, it was discovered that results were more consistent among male animal studies than male human studies. Hence, the researchers stressed the importance of well-designed human clinical trials with larger sample sizes [10].
Another study that was published around the same time looked at the effectiveness of D-Aspartic Acid on basal testosterone levels of resistance-trained men. Aged between 18 and 36 years, these men were selected on the basis of their regular resistance training. After 12 weeks, the team found that the amino acid was ineffective at changing testosterone levels or positively affecting training outcomes [11].
What caught us by surprise is the findings of one source that reviewed a study conducted over the span of two weeks. When subjects were asked to take a high-dose supplement of 6 grams per day, it led to a decrease in testosterone in young men who trained [12]. Like the above source said, more research is definitely needed for this ingredient. It is unclear as to why the age group has been restricted to younger men. It is also unclear why studies on its effects when combined with other testosterone boosting ingredients were not addressed.
Fenugreek
Fenugreek is a clover-like herb that is mainly grown in Mediterranean regions, Southern Europe and Western Asia. With the goal of evaluating the efficacy and safety of the glycoside fraction of fenugreek seeds on muscle anabolism and androgenic hormones, among others, a team of researchers set out to find 60 healthy subjects who would be given this herb for 8 weeks with a resistance training program. In the end, they found that the herb significantly improved anabolic and androgenic activity in these men. Moreover, their body fat levels were also improved without any reduction in their muscle strength [13].
Another study with healthy men ranging between the ages of 43 and 70 also found significant improvements. Precisely, these men were given fenugreek supplementation for 12 weeks, and consequently, both total serum testosterone and free testosterone increased in comparison to the placebo group. This permitted the team to affirm that fenugreek is an “effective treatment for reducing symptoms of possible androgen deficiency, improves sexual function and increases serum testosterone in healthy middle-aged to older men.”
This same source also reported on a second study that considered fenugreek intake by healthy men between 25 and 45 years of age. Researchers are said to have reported that testosterone levels for this age group remained within a normal range [13]. Finally, we have a systematic review that wanted to evaluate the effect of fenugreek extract on total testosterone levels in males. Clinical trials dated up to November 2018 were searched by the team on Medline, Scopus databases, Cochrane Library, Web of Science, and Google Scholar. Using random-effects modelling, a conclusion was reached: “fenugreek extract has a significant effect on total serum testosterone [14].”
Vitamin D3
Vitamin D3 is a fat-soluble vitamin that supposedly helps with calcium and phosphorus absorption. In fact, this vitamin is crucial for upkeeping healthy and strong bones. In terms of male health, we stumbled upon a study that examined the role that vitamin D3 might play in testosterone levels. The selected subjects were healthy, overweight men who underwent a weight reduction program. Split between a control and placebo group, the former was given vitamin D for an entire year. As a result, the team found a significant increase in total free and bioactive testosterone levels [15].
One of the researchers of a study titled, Vitamin D and sex steroid production in men with normal or impaired Leydig cell function, Martin Bloomer Jensen, explained the following about their study:
“What is new about this study is that we can show that vitamin D influences testosterone production. There appears to be a direct link, and one may speculate whether supplementation of vitamin D for vitamin D-deficient men may give a clinically relevant increase in testosterone.”
As far as research goals go, the team did manage to find that vitamin D affects testosterone production directly in the testicles. That said, Bloomer made the case that a larger study will be needed to make firmer conclusions. For the time being, he is optimistic that vitamin D is helpful because it has been proven to support men who have been suffering from low sperm production and infertility [16].
Finally, we stumbled upon yet another study that evaluated the efficacy of vitamin D supplementation on serum testosterone levels in men with low total testosterone levels at the baseline. To our surprise, no significant treatment effect was found between the vitamin D3 group (i.e., intake of 20,000 IU) and the placebo after 12 weeks of intake. The same appears to hold true in regard to “free testosterone, free androgen index, SHBG, estradiol, follicle-stimulating hormone, luteinizing hormone, metabolic characteristics and body composition [17].”
Zinc
Zinc is a nutrient that is naturally found in cells throughout the body. Its main role is to scavenge and eliminate free radicals and toxins, while other responsibilities include protein and DNA production and contributing towards the genetic material in all cells [18]. One study that explored the relationship between cellular zinc concentrations and serum testosterone of 40 healthy men between 20 and 80 years of age found a significant correlation. Specifically, the team noted that dietary zinc restriction was associated with a decrease in serum testosterone after 20 weeks [19].
Upon searching studies pertaining to erectile dysfunction, one that analyzed the effect of zinc on sexual competence of male rats. Researchers were able to show that zinc therapy did, in fact, improve sexual competence and that such an effect was dose-dependent. Having said that, more studies might be needed to ensure that the same improvements hold in cases of sexual dysfunction [20].
Finally, we have a study that managed to establish a link between a lack of smell and low testosterone. In this case, it was argued that younger men who lack a strong sense of smell are zinc-deficient and, therefore, might have reduced libido. Moreover, it was explained that “Zinc not only impacts the level of testosterone, but may cause a loss of the ability to detect subtle chemicals that induce arousal [21].”
Magnesium
Magnesium is a type of mineral that oversees hundreds of enzymic reactions in the human body. It mainly tends to muscle and nerve function while taking extra measures to support immune function and blood pressure levels, writes one source [22]. A study that was performed to assess how four weeks of magnesium supplementation and exercise might affect free and total testosterone levels arrived at the conclusion that both types of testosterone levels increased at rest before and after exercise. The increases were supposedly more prevalent in those who exercise as opposed to sedentary individuals [23].
In addition, one review that looked at the relationship between testosterone and magnesium supplementation highlighted that men “with impaired magnesium status and [testosterone] deficiency could benefit from magnesium and/or [testosterone] treatment targeting physical performance.” A common sentiment that was expressed on numerous occasions is that larger samples need to be collected in order to affirm such results.
In all truth, the authors of this piece believe that if such results can be replicated with larger data, then the combination of hormonal and mineral replacements can go a long way, especially when it comes to preventing “the onset of disability in the elderly [24].”
Vitamin B6
Vitamin B6 is an essential nutrient that is involved in the processes of gluconeogenesis and glycogenolysis, and immune function. A rats model with a mission to administer vitamin B6 supplementation for the purposes of assessing testosterone levels concluded that rats deficient in the nutrient either have a reduced rate of testosterone production or an increased rate of metabolic clearance [25].
Another study that combined vitamin B6 with zinc and magnesium (i.e., also referred to as ZMA) indicated that the right ratio of ZMA led to an increase in testosterone after 8 weeks of ingestion. However, any additional increase in concentration did not bring any added benefits [26]. A source on a mission to shed light on testosterone-boosting solutions wrote that B6 is crucial for processing and breaking down protein, carbohydrates, and fats.
In addition, it is trusted to enhance cognitive function, energy levels and possibly, testosterone production. Most of all, when individuals are vitamin B6-deficient, the brain is triggered to increase estrogen production, which, as we all know, is a female sex hormone [27].
Frequently Asked Questions (FAQS)
What is the difference between normal and free testosterone levels?
Normal (or total) testosterone levels are those that have been bounded to a protein called sex hormone-binding globulin (SHGB). When testosterones are not bound to SHBG, they are biologically active or termed “free testosterone.” Even though some limitations need to be reflected upon, total testosterone levels usually serve as a measurement for the severity of hypogonadism. On the other hand, we have free testosterone, the more beneficial type, because it produces sexual characteristics of men and plays a significant role in men’s features, cell production, bones, and muscle health.
Who are testosterone boosters suitable for?
Since, on average, testosterone levels are said to gradually drop with every year after the age of 30, men who are closer to this age should consider this added measure. Our research suggests that such solutions are most helpful for men between the ages of 30 and 60. That said, the most common reasons why men typically seek out testosterone boosters are to reverse hypogonadism, to increase their overall physique/build and sexual drive, to enhance sexual performance, to experience sustainable erections, and for those who are in need of a mood and energy hike.
Is it safe to take testosterone boosters?
Testosterone boosters are generally safe to take, but age appears to be a limiting factor as well as one’s health. Specifically, men over the age of 60 might want to consult a physician prior to its use. The main reason for this has to do with the mere fact that complications may arise depending on one’s respective health and medical history. In addition, some studies have shown that those who are diabetic are highly unlikely to benefit from such support systems. Finally, anyone with a pre-existing heart and/or prostate disease should refrain from taking testosterone boosters altogether.
How can I tell with certainty that testosterone levels have dropped?
The best bet is to get a serum testosterone test done. This test measures the level of testosterone found in the blood and usually varies based on age, gender, and health history, among others. For better readings, the same test should be conducted more than once and at different times of the day. To further elaborate, individuals will want to stray away from antifungal and hormone medicines to prevent under or overstated values [28].
Of course, there are other tests that could be conducted as well (i.e., follicle-stimulating hormone test, luteinizing hormone test, thyroid-stimulating hormone test, biopsy for testicles, MRI, semen analysis, and tests for the pituitary gland); however, for utmost certainty, consulting a physician is the most reasonable move to make.
What can low testosterone levels lead to?
As mentioned earlier, low testosterone levels might increase body fat and weight, exhaustion, and the rate at which available testosterone is converted to estrogen, as well as decreases in muscle mass, erections, sleep quality, mood, body hair, sexual drive, and performance and many appearance-related factors.
Are there any dietary approaches to boosting testosterone levels?
For people looking to make dietary changes, some natural ways to increase testosterone levels include increasing protein intake, finding food sources that are high in good cholesterol levels, an enzyme called bromelain, monounsaturated fats, and diindolylmethane-rich (i.e., broccoli, bok choy, brussel sprouts, cauliflower, cabbage and arugula, zinc, magnesium, and fenugreek to name the least). Anything filled with processed sugars, junk food, and/or soy products are frowned upon.
What lifestyle choices can further enhance testosterone?
Losing weight can be a great way to increase testosterone levels. In addition to dietary changes, i.e., seeking food sources that promote testosterone boosting and intermittent fasting, individuals can also consider different exercise regimes. Some examples include resistance training, weightlifting, HIIT training, and boxing/martial arts. As crucial as exercise and diet are, factors such as sleep quality, stress, gut health, going over potential side effects of prescribed drugs/medications, and sexual intercourse need to be rectified for utmost results.
Does a higher testosterone level imply bigger balls?
Large testicles are allegedly associated with high levels of testosterone, while smaller testicular volume has been linked to a reduction in sperm production.
What time of the day are testosterone levels the highest?
As per a number of sources, the consensus is that testosterone levels peak in the morning and diminish with every passing hour unless, of course, some of the recommended methods for naturally boosting testosterone levels have been fulfilled.
On average, how long will it take to increase testosterone?
It can take anywhere between four and six weeks or as much as six months, depending on each individual case. As previously mentioned, there are a number of factors that help to better understand why one person is likely to have higher levels of testosterone compared to others.
Final Thoughts
All in all, testosterone boosters are a helpful addition to have for men who are struggling to get their testosterone levels up and running. As seen throughout this guide, the supplement industry carries endless options, but with every added criterion, the options can be narrowed down. We are confident in the processes that the companies listed in our top 11 testosterone boosters follow to ensure maximum strength and results, and safety.
Specifically, the knowledge that they have on testosterone and male health (through R&D) was noticed, and this is crucial, seeing that it reflects what will be included in formulae. Furthermore, our picks for companies have gone above and beyond to educate consumers and support their claims without over-exaggerating results. Finally, our top 11 meets price as a factor, and this was important to us because of the need for increased accessibility.
One key takeaway that should remain in the back of everyone’s minds is that testosterone boosters are not proven to work for all men. As mentioned earlier, there are so many factors to consider, and these, in turn, will either enhance, reduce or leave testosterone levels unchanged. Before jumping into a product, we ask that everyone at least gets blood work done to confirm that testosterone levels are, in fact, low.
From here, it is always advisable to consult a physician to get an opinion on healthy approaches. For example, if any of these supplements are of interest, bringing the supplement’s fact to the physician is also a good approach. Regardless of how things turn out, individuals should value and respect their medical histories and current conditions before taking anything new!
