Best Testosterone Boosters UK that Work
1. Best Vitamins and Minerals for Testosterone
As well as some great testosterone-boosting supplements on the market – which we will come to shortly – there are some key standalone vitamins and minerals that are proven to help testosterone. They include:
VITAMIN D3 AND TESTOSTERONE
Vitamin D is synthesised in our bodies when we’re exposed to sunlight, and it’s a powerhouse nutrient. Heavily involved in many aspects of health, research shows there’s also a link between low levels of vitamin D and low levels of testosterone.
This is a concern when you consider that up to 1 billion people worldwide are deficient in the micronutrient. Our ability to synthesise vitamin D also falls with age – so this is a useful vitamin for older men who are vulnerable to falling T levels anyway.
Younger men could also benefit from vitamin D supplementation. The NHS recommends that everyone supplement with Vitamin D – in form D3 – during the autumn and winter months when the UK doesn’t get as much sun. (People who aren’t outside much or who have darker skin should supplement all year round).
Studies have shown that middle-aged men in particular who are deficient in vitamin D3 benefit from vitamin D supplementation – taking additional D3 helps to boost their testosterone levels and, as a bonus, also improves erectile dysfunction.
In another year-long study, 65 middle aged men who took 3,300 IU of daily vitamin D increased T-levels by 20% compared to those who didn’t supplement.
The NHS recommends supplementing with 10 micrograms of vitamin D3 (400IU) daily, though the U.S. for instance recommends more. The NHS recommend not to take any more than 100 micrograms (4,000IU) a day.
WE RECOMMEND: Performance Lab D3 + K2.
We’re big fans of Performance Lab and our next few recommendations will involve some of their top products. Their D3 + K2 product is ideal for men wanting to boost low testosterone levels as both vitamins are known to contribute to maintaining and potentially boosting T levels.
ZINC AND TESTOSTERONE
Zinc is another powerhouse nutrient that is heavily involved in testosterone synthesis. As such, zinc deficiency is often linked to low levels of testosterone. You can’t store zinc in the body so you either need to get enough from your diet or supplement.
Zinc supplementation has been proven to encourage the promotion of testosterone in the testes and may also improve sperm quality in men with low T levels and infertility.
Note that zinc supplementation is likely to be more effective in men with low zinc levels in the first place.
The NHS recommends 9.5mg of zinc a day for men.
WE RECOMMEND: Performance Lab Zinc.
Performance Lab Zinc is an incredibly clean product that is suitable for vegans. Made using Performance Lab’s NutriGenesis manufacturing process with nature-identical nutrients, it includes 15mg of zinc a day. The NHS says that up to 25mg of zinc a day should be safe.
MAGNESIUM AND TESTOSTERONE
Magnesium is essential for hundreds of processes in the body, including the production of testosterone. Taking a magnesium tablet has been shown to significantly increase testosterone, especially in men who are deficient.
According to recent data, as much as 10-30% of the population of developed countries may have ‘subclinical magnesium deficiency’.
Scientists also suggest that recommended daily levels of magnesium, while enough to avoid outright magnesium deficiency if adhered to, may not be quite enough for optimal health and longevity.
One study showed that magnesium supplementation increased free and total testosterone levels in both sedentary and active men, with the highest increases seen in the latter group.
Another bonus of magnesium supplementation is that it can improve your sleep quality. Getting a good night’s sleep is crucial for optimal testosterone production: indeed, low T levels can interfere with sleep.
Interrupted sleep in turn reduces testosterone levels further, contributes to erectile dysfunction and lowers sperm count.
Magnesium helps sleep by reducing anxiety and depression levels, calms the central nervous system and treats sleep disorders.
WE RECOMMEND: Performance Lab Magnesium.
Performance Lab Magnesium is a premium magnesium supplement, providing 150mg of magnesium – providing 40% NRV. It’s a decent dose of nature-identical nutrients, meaning you should absorb it well.
It’s also one of the cleanest forms of magnesium around – it contains no allergens, gluten, caffeine, synthetic additives, soy or artificial preservatives. It’s GMO-free and non-irradiated, also vegan friendly with plant-based capsules.
Best Testosterone Boosters: Ready-Made Supplements

A Buyer’s Guide to Testosterone Boosting Supplements
Why is Testosterone Important?
Testosterone is the primary male sex hormone (women produce testosterone too but to a much lesser degree) and is influential in a wide range of bodily processes — from helping the male sex organs to develop correctly, to sperm production, libido, and sexual performance. It also has a significant impact on muscle mass, bone strength, fat distribution, and the production of red blood cells. In fact, testosterone is implicated in virtually every bodily process there is.
What Happens When Testosterone Falls?
So, what happens when levels of testosterone start to fall, as they do by 1% a year from the age of 30 onwards? Falling testosterone can make you weaker (reduced muscle strength), bones frailer, cause hair loss, and make you more prone to putting on weight. It can also impact your sex drive, disturb your sleep, and affect your mood. Simply put, it’s not something you want.
So, how can you delay, prevent, or reverse that fall? You can take a testosterone-boosting supplement.
What are Testosterone Boosting Supplements?
Testosterone boosters, or T-boosters/ test-boosters as they’re also known, are a type of dietary supplement — generally a natural one — containing ingredients such as vitamins, minerals, herbal extracts, and amino acids. Their aim is to increase the testosterone in your body. The good ones, such as the ones recommended on this page, do so by encouraging your natural T-producing hormones to get to work and/ or by preventing other hormones from damaging or converting that testosterone into the female hormone, oestrogen.
T-boosters can help men whose natural T levels are falling, as well as offer younger men extra muscle power, hence their popularity with bodybuilders.
Not all T-boosters work as they claim, however, so you are advised to do your research first.
What to Look for in a Testosterone Booster
There are a lot of T-boosters on the market but they’re not all equal — in fact, many are downright rubbish. Here’s what we think you should be looking for in a great testosterone-boosting supplement:
- Proven ingredients: Don’t get side-tracked by buzz or elaborate marketing promises. Look for products that offer clinically proven ingredients. Some of the best ingredients around are D-AA (or its more premium form, D-AA-CC), vitamin D, and ginseng, as well as multi-purpose ingredients, such as ashwagandha. Make sure too that they’re included in effective doses.
- Natural products: Steer away from synthetic testosterone, and instead look for products that increase T in a safe, natural way.
- Multi-path Testosterone Boosting: Do your research, and opt for products that increase your testosterone in more than one way. Some ingredients may encourage different bodily processes to create testosterone naturally, while others may work to prevent hormones that bind to free testosterone, effectively rendering it useless. A really strong testosterone booster will offer more than one way of increasing or maintaining T levels.
- Safety: If you opt for the natural products mentioned above, you should find products that have no side effects and make you feel great.
- User Recommendations and/ or Independent Reviews: Finally, get on the web and see what other people are saying about the product you’re considering. Keep an eye out for any red flags. Independent reviews on review websites (such as ours!) are also a good way to go.
All of the products on our Best Testosterone Boosters UK of 2025 meet the above recommendations, so we’ve done the work for you! Below you can learn more about each of our best testosterone boosters UK recommendations in detail.
BEST TESTOSTERONE BOOSTERS UK – IN DETAIL…
Centrapeak: Best for Male Vitality
Centrapeak is a male vitality pill that pledges to boost testosterone AND enhance your mental well-being too.
It claims to do this by focusing on ingredients that improve your T-levels, as well as including the sort of herbs and nootropics that aren’t often seen in traditional testosterone boosters.
These additional ingredients help to tackle stress, improve libido, reduce anxiety and aid mental cognition. Add these to increased testosterone levels with a knock-on effect on stamina, endurance, muscle strength and energy, and Centrapeak promises to be a potent male vitality stack.
We like its emphasis on mental health as well as testosterone boosting, but how does it work? Let’s investigate to see if it lives up to its promises in all areas…
Pros of Centrapeak
- Centrapeak includes proven testosterone-boosting ingredients, which should improve stamina and endurance.
- Also has a strong focus on tackling anxiety and stress; may also help to reduce stress-related fatigue.
- Centrapeak may also be able to enhance fertility and sperm count.
- The ingredients have been shown to improve mood and subjective well-being in studies.
- All dosages should be clinically effective.
- Offers worldwide shipping and strong customer service.
- Lots of positive comments and reviews from buyers.
Cons of Centrapeak
- Centrapeak does have a quality price tag, but user reviews show that it is a quality product too.
- Only available direct from the manufacturer.
- The magnesium dosage could be a bit higher.
- Not the strongest product for those seeking bodybuilding gains.
Centrapeak Ingredients
They include:
Zinc, Magnesium and B6: Centrapeak’s version of ZMA, the popular supplement created to build muscle strength and stamina, help recovery after exercise and improve sleep. Zinc helps to directly raise T-levels, magnesium promotes better sleep which also improves testosterone and B6 both promotes androgens and regulates the hormones oestrogen and prolactin, which can otherwise damage T-levels.
Vitamin K2 is particularly useful for tackling age-related falls in testosterone; vitamin D supplementation prevents deficiency which has been linked to low T-levels, and Indole-3-Carbinol blocks aromatase, which converts T into oestrogen, helping to maintain testosterone levels.
Power hitter Ashwagandha acts as a testosterone booster and a nootropic. It tackles cortisol levels — too much of the stress hormone hinders T production — has been shown to boost muscle mass, AND acts as a potent libido enhancer.
Nootropics Rhodiola Rosea, an adaptogen herb that helps the body to handle stress, and Phosphatidylserine, which helps to create and protect brain neurons, help to boost the cognitive benefits and stress-relief of Centrapeak.
Herb Mucuna Pruriens both reduces stress and delivers L-DOPA that turns into dopamine and more testosterone. It has also been shown to improve sperm count and sperm activity, boosting male virility.
Ancient natural medicine, Panax Ginseng, can also boost testosterone and libido, and provide more nitric oxide to potentially help with erectile dysfunction. While Luteolin is one of the best oestrogen-blockers around, helping to reduce aromatase. It also boosts GABA levels in the brain to improve mood and feelings of wellbeing.
Boron helps to reduce levels of SHBG, the hormone that binds to T, making it no longer available for use, while also improving performance and boosting free testosterone. Also included (added to a later version of the formula) are L-Tyrosine and Maritime Pine Bark. L-Tyrosine helps the body fight stress and sleep deprivation and boosts libido. Maritime Pine Bark improves blood flow, may help to tackle erectile dysfunction, and is a potent anti-inflammatory.
The final ingredient, BioPerine, aids with the absorption of all other ingredients
How Does Centrapeak Work?
Centrapeak works by combining proven testosterone boosters with proven nootropics and adaptogen herbs to reduce stress and anxiety. It’s a clever combination that seeks to tackle one of the biggest barriers to testosterone — high levels of cortisol (the stress hormone) in the body. As a result of its anti-stress and anti-anxiety elements, subjective mood and well-being should increase as should energy and vitality. For this reason, and for the care and attention that has gone into choosing the right ingredients, we consider Centrapeak our favourite male vitality pill and a good one to include in our best testosterone boosters UK. Centrapeak would suit men in their 30s, 40s, and beyond who have stressful jobs or lives.
Why You Should Trust This Brand
Lots of reviews of Centrapeak focus on the ‘phenomenal customer service’ provided by Centrapeak, which is no surprise given its emphasis on quality of production. Centrapeak is made in two facilities in the UK and the U.S. to Good Manufacturing guidelines. There are no hidden ingredients, dosages, or proprietary blends, and Centrapeak boasts a very clean formula — GMO-free, preservative-free, banned substance-free, gluten-free, and suitable for vegans. Companies that go to these lengths to create quality products are not charlatans.
Choose Centrapeak if…
You want something more than just a testosterone booster and would appreciate a supplement that boosts T while also helping your body deal with stress, protect the brain and help improve your mood too.
Prime Male: Best for Older Men
Prime Male combines 12 solid ingredients to make a top-notch testosterone-boosting pill. We love Prime Male, especially for its:
- Target audience: Prime Male is targeted at men aged 30, 40, 50, and over, the age groups that need testosterone boosters the most.
- It’s not often that a formula can make all 12 ingredients work hard, but Prime Male does. All ingredients are either strong proven T-boosters alone, or combine with each other to significantly improve their testosterone-boosting power.
- Prime Male includes substances that work especially for age-related testosterone loss, demonstrating its commitment to its target audience.
Prime Males’ Promise:
To quote the manufacturers, Prime Male can ‘turn back the clock on male ageing’
That’s a heck of a promise. Here’s another one: Prime Male claims that it can boost your T levels to what they were 10, 20, and even 30 years ago, and can do so in weeks rather than months.
The manufacturers are very confident in their product and we agree with them. Everything we’ve seen and tested so far demonstrates that Prime Male is a winning testosterone-boosting formula.
Taking Prime Male or any effective T-booster should help to boost your libido and mood, improve cardiovascular health, give you more energy, help build lean muscle, and strengthen your bones. Prime Male also boasts that its product can aid optimum prostate health, boost brain function, and improve skin.
It Works Because…
Prime Male is so effective because of its three-pronged approach. It…
- Boosts testosterone production directly by using D-Aspartic Acid Calcium Chelate (D-AA-CC) to encourage the production of the body’s Luteinizing Hormone (LH).
- Neutralises Sex Hormone Binding Globulin (SHGB). As much as 60% of a man’s testosterone is ‘bound’ to SHGB, which makes it unavailable for use. Magnesium citrate, nettle root and boron help to reduce levels of SHGB and reduce its strength.
- Reduces the female hormones found in a man’s body. Oestrogen and prolactin are naturally present in the male, but too much can damage testosterone levels. Boron, luteolin, and zinc help to reduce their amounts. One study found that oestrogen levels dropped by 39% after taking 10mg boron for one week.
Other ingredients include:
- Vitamins B6 and D3, both of which help to boost testosterone levels.
- Vitamin K2 is particularly useful in tackling age-related T decline.
- Asian Red Panax Ginseng, perhaps not a direct T-booster but useful in the bedroom. May also help erectile dysfunction.
- BioPerine®, a form of black pepper that encourages absorption, making the other ingredients more effective.
Choose Prime Male if….
You’re in the right age group, want a quality product with premium ingredients, and plan to use it over the long term to maintain healthy testosterone levels, as opposed to seeking a short sharp T boost.
PAIRS WELL WITH
Prime Male Enhance: Virility Pill
A virility pill designed to work in synergy with the original Prime Male. Prime Male Enhance boosts virility three-fold:
- Nutrients improve blood flow and sperm quality
- Proven libido-enhancing qualities fuel your sex drive
- Mood-lifting ingredients boost your confidence
Let’s get down to what you really want to know: Prime Male Enhance promises to deliver stronger and longer erections, and more satisfying orgasms. As Prime Male helpfully points out, a recent survey shows that nearly half of men in their THIRTIES have occasional problems with gaining and sustaining an erection. Prime Male Enhance promises to tackle this.
It does so via a mix of 11 nutraceuticals, including:
- Ginseng, maca, and oat straw to help you ‘feel confident in your performance and sexual enjoyment’
- Tribulus Terrestris, selenium, damiana, and muria puama (colloquially referred to as “erection root”) increase desire and help you develop an ‘Alpha sexual mindset’
- Saw palmetto, L-arginine, B-vitamins, and zinc to give you the energy to deliver and the ‘blood flow necessary to impress’.
Prime Male Enhance can be used alone but has been designed to be taken alongside Prime Male for extra strength.
4.
TestoFuel: Best T-Booster for Muscle Gain
TestoFuel is great because of the difference it offers to our choices above, adding variety to our list of best testosterone boosters UK. Whereas Testo Lab Pro brings ancient medicine to the modern-day and Prime Male seeks to aid the older generation, TestoFuel unashamedly targets young weightlifters.
As it says on its marketing literature and website, if you’re ‘struggling to pack on the muscle’ or ‘not making the gains you’d hoped for’, the ‘missing link’ could be testosterone.
The Science…
Testosterone is connected in some way to pretty much every organ in the body, and that’s especially true for the muscles. Increasing your levels of testosterone can help the body to recover quicker after workouts, giving you an energy boost at the same time. Meaning you can work out more often and harder than before, helping to build bigger muscles.
You’ll be stronger, have less body fat, improved muscle mass, more motivation, and enhanced libido, promises TestoFuel.
It Works Because…
Graphic courtesy of TestoFuel
The manufacturers of TestoFuel know their market and have combined effective T-boosting ingredients with performance enhancers. A popular mix for weightlifters in their 20s seeking an extra edge.
We’ll be honest: TestoFuel uses many of the same proven substances as Prime Male. We’re talking D-AA (D-Aspartic Acid), vitamins D3, zinc, and magnesium. All have been proven to help boost testosterone production, either by increasing it directly, stopping it from being rendered unusable by SHGB, or by reducing the female hormones in the body. TestoFuel’s supply of D-AA is particularly high at a dosage of 2,000mg.
Here’s where TestoFuel differs from Prime Male: It introduces a couple of new ingredients into the mix – fenugreek and oyster extract.
- Fenugreek used to be a controversial choice but more and more studies have shown that it can improve testosterone levels and symptoms related to low T-levels, such as poor libido. An eight-week study, for instance, with 49 athletic men demonstrated that taking fenugreek daily improved testosterone levels, plus strength and body fat too. It’s the perfect inclusion in TestoFuel.
- Oyster Extract gives another powerful boost of zinc — a known T-booster — and also adds an aphrodisiac and libido-boosting effect. We don’t believe anyone would complain about that!
Other ingredients:
- Vitamin D, included here as D3, is a preferred form for testosterone. A vitamin D deficiency can lead to lower levels of free testosterone.
- Vitamin K2 complements vitamin D3 and may help to ‘maintain steady levels of testosterone.’
Choose TestoFuel if…
You are ideally in your 20s and want a helping hand to boost testosterone so that you can build muscle. A couple of performance enhancers are also a welcome addition.

Hunter Test: Best for Low Testosterone
Don’t be fooled by the fact that Hunter Test is fifth on this list; this is a superior testosterone booster. There just happen to be several other excellent T-boosters to sit alongside it.
Hunter Test is made by respected UK supplement company Roar Ambition, and here’s what we love about it: It’s part of a male-focused range of products that includes a strong nootropic (Hunter Mind) and an excellent fat burner (Hunter Burn). All can be used together, making an impressive male-oriented health package.
Of course, if you only want the T-booster, then Hunter Test also works perfectly well on its own, thanks to its combo of DAA, ginseng, ashwagandha, boron, zinc, magnesium, and vitamins D3 and K2.
It’s a combination that both provides short-term benefits to testosterone levels, potentially combats T-deficiency, and fights stress that can impact your testosterone levels. Hunter Test is particularly useful to support infertile men or men deficient in testosterone — so potentially any man over 40 years of age!
Full ingredients include:
Overall, this is a very strong product primarily designed to support older men with the likes of DAA and Ashwagandha allowing you to regain some control over your hormones.
