Man over 50 showing signs of high testosterone

Are you seeking a natural way to boost testosterone after 50? If so, it’s for good reason too. Testosterone is the powerful androgen hormone essential to your masculine health. It’s integral for helping maintain muscle mass, manage body fat, bolster virility, and regulate mood – four valuable aspects for your wellbeing. In this article, we’ll reveal the very best testosterone boosting supplements for men over 50.

Testosterone after 50

When you were younger testosterone helped you forge a fit, lean, and muscular physique. As a potent androgen hormone, it was responsible for the masculine traits you developed during puberty. Strength, power, virility, dense muscle mass, and high libido were all made possible because of the testosterone you produced.

More specifically, testosterone controls aspects such as:

  • Penis and testes development
  • Voice deepening, sexual organ growth, and facial/pubic hair during puberty
  • Libido, sexual performance, and sperm production
  • Bone density and strength
  • Muscle strength and size

As a man over 50, testosterone still plays a pivotal role in your wellbeing. It is a kingpin in your health, although now it won’t be present in such an abundance as it was in your 20s. Unfortunately, you may have felt the side effects of falling androgens already.

This is because natural testosterone levels decline once you reach the ages of 30-40 [1]. By now, your production has already been slowing for over a decade. According to statistics, your masculine hormone volume could be as low as 242 ng/dL., which is, unfortunately, lower than the average baseline of 280 ng/dL [2] [3].

Low testosterone

Many men over the age of 50 experience the effects of low testosterone. However, rather than understand their reduced hormone production may be responsible, they accept the circumstances as inevitable signs of aging.

According to Harvard University;

“As men reach their 50s and beyond, this may lead to signs and symptoms, such as impotence or changes in sexual desire, depression or anxiety, reduced muscle mass, less energy, weight gain, anemia, and hot flashes.” [4]

Detecting the symptoms of low testosterone allows you to monitor how your masculine hormone levels are performing. If you have at some point in recent times felt these occurrences for yourself, your testosterone could be low. Depending on the current amounts of the androgen hormone you are producing, you may just experience one or many symptoms.

A widely recognized treatment for low testosterone is testosterone replacement therapy. However, this may only be prescribed by a trained medical professional and requires certain cover in alignment with your medical insurance. If you are diagnosed with low testosterone, doctors do not always turn to TRT as the first course of action. At the time of writing the long-term effects of testosterone replacement therapy are uncertain [5].

Testosterone boosters do not need to be prescribed by a medical professional. This is because they are not created as a form of medication, but as hormone support complexes to bolster a well-balanced diet. The nutrients inside them are selected specifically to aid male health and help men reclaim an optimal testosterone balance.

Key point: Testosterone boosters do not require a prescription. Instead, they are legal, widely distributed health support supplements, used by many men over 50. Read on to see the best testosterone boosters available for this age group.

Before we go further it is important to recognize that none of the following individual supplements have been proven effective under scientific conditions. All studies and papers referenced refer to specific ingredients only. 


Best Testosterone Boosters for Men Over 50

Four bottles of Hunter Test, the best testosterone booster for men over 501. Hunter Test

Our primary choice testosterone booster for men over 50 is Hunter Test. After only entering the market in late 2018, this supplement continues to impress, standing out as a leader in the men’s wellbeing market.

Rather than raise testosterone to benefit aesthetics, Hunter Test takes a holistic approach to masculine health. It’s potent, powerful, and cutting-edge formula was developed specifically for high achieving men looking to optimize their hormones.

It’s for these reasons we recognize Hunter Test as the ideal match for any man over 50. The creators themselves aim it at professional men, who aspire to achieve in all aspects of their life, not just their appearance. Therefore, Hunter Test has tailored its ingredient choice and sizes to suit this type of busy, ambitious man.

Each ingredient found within Hunter Test is backed by substantial scientific research. Additionally, by adopting a streamlined formula, Hunter Test is able to deliver some of the biggest serving sizes in the field. There are no filler ingredients diluting any capsules, nor are there unnecessary, quality-reducing proprietary blends.

Because of this, our experts recognize Test as a standout supplement in terms of effectiveness. It has the highest overall potency out of our best testosterone boosters list as well as boasting the most up to date formula.

Hunter Test ingredients

Vitamin D3

Vitamin D is a steroid hormone naturally produced in the body when the skin comes in contact with sunlight. Research shows it to be integral to healthy testosterone production [5].

As modern industry develops, many men spend more time indoors, which is the leading cause ofvitamin D deficiency [6]. However, one study has shown that men who supplement with 3,332 IU of vitamin D for 365 days can raise their testosterone production significantly [5].

D-Aspartic Acid

D-aspartic acid has been shown to boost testosterone in certain men by releasing luteinizing hormone, which encourages the testes to increase testosterone generation [7]. This is how D-AA is said to positively influence blood testosterone levels [8].

According to one study, supplementing with d-aspartic acid showed testosterone increases in both athletes and impotent men, while the impotent men tested also experienced increased semen quality [8]. Furthermore, additional research into the impact of D-AA suggests that testosterone can be boosted in as short as 6-12 days [9], with semen count rising by up to 100% [10].

Zinc

Zinc is an essential mineral you must consume to live healthily.

One of its roles is to enable better testosterone flow into the bloodstream. Making it vitally important for regulating serum androgen hormone levels.

An important paper published in 1996 displayed a clear connection between zinc and testosterone. During the study, the research team found that the older test subjects who supplemented with zinc almost doubled their free testosterone levels [11].

Indole-3-Carbinol

I-3-C is the compound believed to give cruciferous, green vegetables their anti-cancer properties. Indole-3-carbinol’s ability to help prevent prostate cancer should be of significant importance for men over 50 [12].

Yet, I-3-C earns its place in this testosterone booster for its estrogen-blocking effect. Estrogen is the female hormone that can hinder testosterone production [13].

Magnesium

Magnesium is another essential mineral much like zinc. Scientists say it is responsible for upwards of 600 biochemical reactions inside the body; one of which is influencing testosterone status [14] [15].

Recent research suggests that up to half of the US and European population may be Mg deficient [16] [17]. This raises concern for men over 50, as magnesium is shown to help the body fight many markers of mortality, such as diabetes and high blood pressure [18] [19].

Ashwagandha

Although primarily used in traditional medicine, modern scientists believe Ashwagandha can help boost testosterone. It does this by controlling cortisol, the stress hormone that can negatively influence testosterone production [20] [21].

Additionally, Ashwagandha has also been proven to increase both muscle mass and strength. This might be an important factor for you to consider as a man over 50 [22].

Taking Hunter Test

You should take six capsules of Hunter Test per day according to the manufacturers. Out of all the supplements on our list, this is the highest amount, but the serving suggestion has been planned intelligently.

Dispersing six capsules across 24-hours allows for more potent individual servings. Additionally, this method also allows for an even flow of ingredients entering the body. We believe this to be a very effective and efficient way of supplementing.

When we inspected the Hunter Test label, we were advised to take three, two-capsule servings. Each one should also be accompanied by food and a full glass of water.

Therefore, we at Greatest Physiques recommend taking Hunter Test as follows:

  • 2 capsules with breakfast
  • 2 capsules with lunch
  • 2 capsules with your last main meal

Carrying out this method will allow for optimal supplementation. We do not advise taking all six capsules in one sitting.

Hunter Test Reviews

When looking to purchase a supplement it is advised to seek out multiple reviews. This way you see a broad range of opinions, allowing you to make a more informed choice.

We at Greatest Physiques understand this too. Therefore, we have looked toward other supplement authorities online to see their opinions on Hunter Test. What follows are some of the key excerpts we found:

  • “We believe this is the best testosterone booster a man can buy. Natural, potent ingredients along with some of the best servings sizes available combine to create one of the most intelligent testosterone boosters we’ve ever seen.” – (SpotMeBro.com)
  • “If you are already making improvements to your lifestyle, Hunter Test could be a great addition. It offers credible testosterone boosters that work along more than one bio-pathway, contains a huge [serving] of D-AA, and includes pretty decent [servings] of the rest.” – (SupplementReviewsUK.com)
  • “Overall, we think that this is an excellent supplement that contains all of the main ingredients we look for in a product like this. What’s more, Hunter Test also uses the best doses of the top ingredients, which is always important. To wrap things up, we feel that Hunter Test is one of the strongest products on the market in this category right now.” – (HumanWindow.com)
  • “Is Hunter Test Premium Testosterone Booster good value for money? As we have already mentioned, this is a premium product, so you should not expect it to be a bargain-basement price.” – (LegWork.com)

As you can see many online reviews fall in favor of Hunter Test. Potent, high-quality ingredients impress the most, which has solidified Test’s place in the market.

The only apparent negative comments come in relation to price. As a premium product, Hunter Test carries a higher cost. While it is generally agreed that Hunter Test is still good value for money, this price range might not be suitable for some men.

Our team always recommend purchasing a top-tier supplement over a lower-quality alternative – even if the latter is cheaper. Doing so allows you to supply your body with the cleanest, high-grade ingredients, with minimized risk of cross-contamination during the manufacturing process.

Closing thoughts on Hunter Test

Although Hunter Test is still a newcomer, it has quickly become a revered testosterone booster. The potent, cutting-edge formula is undeniably its strongest feature, which we rate highly. Each ingredient has been selected for the busy, professional man to support his lifestyle. As a review team, we feel this aspect lends itself perfectly to any male over 50.

Six daily servings also allow for generous amounts of each key ingredient. This bolsters the power and effectiveness of Hunter Test, which is one reason it placed first on our list. Each capsule is created in accordance with good manufacturing practices too, meaning there is minimal chance of any cross-contamination occurring.

If the premium price of Hunter Test is within your range, we recommend purchasing this product. The formula should prove extremely beneficial for men over 50, especially those leading a busy, professional lifestyle.

Bottle and boxes of Prime Male testosterone booster2. Prime Male

Taking second place and only slightly behind Hunter Test is the popular Prime Male. Engineered specifically for men over 30, Prime Male features 12 carefully considered ingredients, chosen for their ability to enhance masculine health in this age group.

Much like Hunter Test, Prime Male is an all-encompassing testosterone booster. Its primary aim is providing men with the necessary nutrients to reclaim their virility, not just bolster aesthetics. As such, Prime Male is not a bodybuilding or athletics driven supplement, which we feel is important for men over 50.

Prime Male’s website says it can address the three biggest barriers to healthy testosterone. These are luteinizing hormone, sex hormone binding globulin, and female hormones and prolactin. After inspection, we can confirm Prime Male’s formula should be highly effective at combating these three barriers.

In the following section we’ll break down just how this is possible:

Prime Male Ingredients

Vitamin D-3

Vitamin D is a steroid hormone generated when our skin comes into contact with sunlight. However, recent research estimates that around 1 billion people on planet earth are vitamin D deficient [6].

This should raise concern for men of all ages, as healthy vitamin D levels is closely related to testosterone. Studies have also shown that supplementing with vitamin D may help men reclaim hormonal balance [5].

D-Aspartic acid

D-AA is a non-essential amino acid that has been shown to influence testosterone production. It does so by causing the release of luteinizing hormone, which in turn signals to the testes to create testosterone [7].

Researchers have indicated that supplementing with D-AA can positively influence testosterone levels in certain men [8] within as short as 6-12 days [9]. Furthermore, one study saw D-AA supplementation increase testosterone by 60% and raise semen count by 100% [10].

Black pepper extract as BioPerine®

BioPerine® is a patented extract taken from black pepper fruit. Primura has included it in the Prime Male formula to improve the bioavailability and absorption of other key ingredients [23].

Boron

Boron is a trace mineral with vitally important roles in regulating metabolism. It’s also been proven to increase magnesium absorption, and help the body to utilize testosterone, estrogen, and vitamin D more efficiently [24].

Additional benefits of boron that support the wellbeing of men over 50 also include; raised levels of antioxidant enzymes, improved cognitive performance, reduced inflammatory biomarkers, and protection against oxidative stress [24].

Vitamin B6

B6 can benefit testosterone production by stimulating androgen receptors. This, in turn, spurs the testes to direct more testosterone into the bloodstream, and as a result, scientists have found a link between low testosterone and B6 deficiency [25].

Research suggests that higher amounts of vitamin B6 might reduce estrogen by up to 30% [26]. Furthermore, men with B6 below baseline are 3.5 times more inclined to experience enhanced cognitive decline over a four-year period[27].

IngredientAmount Per Serving% Daily Value
Vitamin D35000 IU833
Vitamin K2 (as Menaquinone-7)45 mcg50
Vitamin B6 (as pyridoxal 5 phosphate)7.5 mg577
Magnesium (as magnesium citrate)100 mg24
Zinc (as zinc citrate)30 mg273
D-Aspartic Acid Calcium Chelate1600 mg**
Asian Red Ginseng 4:1 extract (root)120 mg**
Luteolin60 mg**
Mucuna Pruriens (seed) Ext. (standardized to 15% levadopa)300 mg**
Nettle Root 10:1 extract160 mg**
BioPerine®10 mg**
Boron (as boron amino acid chelate)5 mg**
** = No DV

Taking Prime Male

Like our first choice Hunter Test, Prime Male follows a separated serving pattern. This allows for a better, more even distribution of ingredients throughout the day.

Men who purchase Prime Male are asked to take four single capsules each day. These should also be accompanied by food to aid digestion, which makes mealtimes a convenient point to take this supplement.

Therefore, we suggest the following:

  • 1 capsule with breakfast
  • 1 capsule with lunch
  • 1 capsule mid-afternoon with a small portion of food
  • 1 capsule with your final full meal

Our experienced review team sees this as an intelligent approach. Consequently, we do not advise taking all four capsules in one serving, as this may impact Prime Male’s performance. Always act according to the manufacturer guidelines.

Prime Male Reviews

Prime Male has been on the market for several years now and has since established itself as a frontrunner. As a result, many reviews can be found online, with a large majority being in favor of the product.

According to these reviews, Prime Male’s standout feature is that it is engineered for the 30+ man. It is one of the less aggressive testosterone boosters on the market, relying less on heavy amounts of D-AA, and instead offering 12 individual ingredients. While the Prime Male formula might not be as streamlined or up to date as Hunter Test, it’s still impressive.

Other online authorities’ opinions include:

  • “We like this supplement a lot and rate it as one of the best products for older men around at the moment.” – (HumanWindow.com)
  • “We literally like everything we see in Prime Male. From the premium forms of topnotch testosterone-boosting ingredients to their respective doses, Prime Male has invested a lot of money in their formula and the results show.” – (NutshellNutrition.com)
  • “Prime Male avoids many filler ingredients other brands put into their products. Boron, D-aspartic acid, and Zinc all have research to support their use. If you can swallow nearly $70 a month, then Prime Male is worth a shot” – (IronJunkies.com)
  • “The over 30s booster market might be a crowded one, but in our opinion, Prime Male tops them all. The Formula, which is the most important part of any supplement, is second to none.” – (TestosteroneResource.com)

As IronJunkies.com points out, Prime Male does have a premium cost attached to it. However, due to the quality of Prime Male, we do believe it is good value for money. The asking price aligns well with the high-grade ingredients, potency, and professional manufacturing process.

*individual results may vary

Closing Thoughts on Prime Male

Prime Male is a premium supplement engineered to help 30+ men reclaim and reinvigorate their testosterone production. Its 12-ingredient strong formula is potent and shows positive signs for effectiveness.

Upon inspection, it’s clear to see the ingredient choice considers men in this age group. As we mentioned in the opening statement, Prime Male is an all-around testosterone booster, not just an aid to enhance aesthetics. Our team was able to find reputable evidence to support all of these ingredient choices too – except nettle root extract.

However, we did see the decision to use 12 ingredients slightly outdated. After examining Hunter Test, we would have preferred a similar streamlined approach. Hunter’s method of only uses nine ingredients allows each one to be included in more powerful quantities. It’s for this reason Prime Male placed in second behind the newcomer.

In closing, we hold Prime Male in very high regard as a testosterone booster for men over 50. While it may not be as impressive as Hunter Test, it still offers premium quality at a more affordable amount. It is in no way a cheap substitute, but another unique, top-tier testosterone booster option.

Two boxes and a bottle of TestoFuel testosterone booster

3. TestoFuel

TestoFuel is the testosterone booster we recommend to over 50s with above average activity levels. This is because it was developed to help men build lean muscle mass, while also reducing body fat.

Unlike Prime Male, TestoFuel is not designed exclusively for 30+ men. However, those over 50 can still benefit from the profile of ingredients within it.

According to the manufacturers of TestoFuel, their supplement is for men of any age looking for a natural way to increase testosterone production. Their website also states that supplementation may; “raise testosterone levels by over 40%; without the need for dangerous, illegal substances.” [28]

Like the two testosterone boosters that precede it in this list, TestoFuel is a premium product, created by using exclusively high-grade ingredients. It is completely void of proprietary blends too, meaning there are no fillers or hidden ingredients. Men who take TestoFuel can be confident that they know what they’re taking.

TestoFuel Ingredients

Vitamin D3

Vitamin D, also known as cholecalciferol, is a steroid hormone you produce when your skin is exposed to sunlight. However, upward of one billion people on earth are deficient in it. This is an alarming figure as low levels of vitamin D is also linked to low testosterone [6] [5].

Men who aren’t deficient in vitamin D show an increased rate of muscle building, energy, and bone strength [29][30][31]. Considering these can decline with age, vitamin D is an important nutrient for men over 50.

D-Aspartic Acid

D-AA is a non-essential amino acid that supports the regulation of testosterone synthesis [8]. It does so by encouraging the release of luteinizing hormone, which directs the testes to produce more testosterone.

Current research suggests that D-AA may increase testosterone within 6-12 days of supplementation [9]. Furthermore, additional evidence sheds light on the possibility of d-aspartic acid boosting testosterone by 60%, alongside a 100% increase in sperm count [10].

Ginseng (Asian)

Asian ginseng has been used a libido enhancer hundreds of years. However, unlike many ancient medicines, Asian ginseng has been proven effective at increasing testosterone [32].

Furthermore, research suggests Asian ginseng can also; improve sleep, cognition, energy, erection strength, and sex drive [33][34][35][36][37].

Oyster powder extract

Oyster meat is the most bioavailable zinc food source, which is why TestoFuel’s creators have added it to their formula [39]. Their intention is to bolster the already ample 10 mg even further for enhanced testosterone support.

Research suggests that the essential mineral zinc plays a pivotal role in increasing luteinizing hormone, which encourages the testes to produce and release testosterone. Consequently, low levels of zinc are associated with sub-baseline testosterone production [11].

Vitamin K2

Also known as menaquinone, vitamin K2 works in conjunction with D3 for enhanced testosterone release [39]. In one animal study, researchers reported a 70% average increase in testosterone after five weeks of K2 supplementation [40].

IngredientAmount Per Serving% EU NRV (Nutritional Reference Value)
Vitamin D35000 IU2500%
Vitamin K218 mcg24

Aspartic Acid (D-form)2300 mg**
Asian Red Panax Ginseng100 mg**
Fenugreek Seed100 mg**
Oyster Powder100 mg**
** = No NRV

TestoFuel Reviews

There are a high number of TestoFuel reviews available online as it’s been on the market since 2012. However, since its release, the initial formula has undergone further testing and improvements. Therefore, although there is an abundance of online reviews, only those written after the formula was updated hold true value.

For this reason, the excerpts shown below are exclusively from this time period. Our team did not believe it appropriate to judge TestoFuel based on outdated opinions.

  • “I had more energy throughout the day. I felt more focused on whatever I was doing.” – (Gabeba.com)
  • “In closing, our team of researchers advocate TestoFuel to anyone serious about boosting their testosterone. This is a premium quality supplement, with a bold and impressive formula developed exclusively from natural ingredients.” – (SpotMeBro.com)
  • “If considered for boosting testosterone, a little or no effect is demonstrated. Some users had noticed no improvement in their testosterone levels, sex drive and muscle mass, while others feel a boost in strength and workouts performance. Testofuel is very good for men over 35 years, where their testosterone levels are already declining.” – (BodyMedia.com)
  • “There are lots of positive customer reviews on YouTube, review sites, social media going years back. It also seems to be popular with older guys too. We found guys 40 and over are even using the supplement.” – (TheSportReview.com)

Again, as with Hunter Test and Prime Male, all reviewers raise the point about TestoFuel’s price. They express that this testosterone booster sits at in the top-tier in terms of cost, which may not suit every man. Yet, because of the premium quality and research behind it, most see TestoFuel as good value for money.

Additionally, many online authorities recommend taking TestoFuel consistently to see results. Our team of experts agrees with this statement, as two to three months of supplementation should provide the best results.

*individual results may vary

Closing Thoughts on TestoFuel

TestoFuel is our final choice in the top three testosterone boosters for men over 50. Although not specifically engineered for this age group, it continues to impress with an athletic and physique focused formula. It’s because of this we recommend TestoFuel to the 50+ man who exercises regularly and wishes to build or maintain muscle mass.

Furthermore, TestoFuel has two sources of zinc, with one being the most bioavailable food source on the planet. There are also ample if not generous amounts of vitamin D, B6, magnesium, and d-aspartic acid for additional testosterone support. Fenugreek is included in the profile too, although the evidence is unclear if this ingredient works for all men.

As a premium supplement, TestoFuel is completely free from proprietary blends. Each ingredient is presented clearly on the side of the packaging, offering a high level of reassurance and transparency. We believe that this enhances TestoFuel’s claims to safety and substantially reduces the risk of side effects.

In closing, TestoFuel still showcases itself as good value for money – even alongside its premium price tag. TestoFuel buyers can be confident knowing they are buying a top-tier testosterone booster made using high-grade ingredients. TestoFuel is also manufactured in either the UK or USA too, alongside good standards that minimize the chance of cross-contamination.

Muscular and athletic man over 50 with high testosterone

Last Word on the Best Testosterone Boosters for Men Over 50

Utilizing a testosterone booster should allow men over 50 can help reclaim hormonal balance without prescription drugs. A high-quality supplement like our top three choices provide the body with nutrients integral for healthy masculine hormone production, alongside other supporting compounds.

Each of the above supplements was selected due to high levels of potential effectiveness alongside premium quality. They are all totally free from proprietary blends, which many low-quality companies use to fill out products or disguise certain ingredients. Our team view a supplement void of proprietary blends is both transparent and trustworthy.

We also considered cost when selecting which three testosterone boosters would make this list. And although each one carries a premium price; we see the monetary ask as a direct reflection on quality. Therefore, our team believes each of the above testosterone boosters to be good value for money. While others may be cheaper, we often find that their potency, manufacturing procedures, and reputation are of a lower standard. We also recommend purchasing reputable, premium products when possible.
