Can Tongkat Ali Increase Testosterone Naturally?

Mar 30, 2026 Uncle Gym

Testosterone has become one of the most talked-about hormones in modern fitness and health. From energy levels to muscle growth, motivation, mood, and libido, testosterone influences far more than just gym performance. Because of that, many people look for ways to support their natural testosterone levels without turning to medical interventions.

One supplement that appears constantly in those conversations is Tongkat Ali.

Often referred to as Longjack, Tongkat Ali is a traditional herbal extract that has been used for centuries in Southeast Asia. In recent years it has exploded in popularity in the fitness and men’s health world, where it’s marketed as a natural testosterone booster capable of improving energy, strength, mood, and performance.

But here’s the important question.

Does Tongkat Ali actually increase testosterone — or is it just another overhyped supplement trend?

The truth is a little more nuanced.

Tongkat Ali may support testosterone levels under certain conditions, particularly when stress hormones are high or when testosterone is already suppressed. But like many natural supplements, it isn’t magic, and understanding how it works is key to using it properly.

Let’s break down what the science actually says.

1. What Is Tongkat Ali and How Does It Affect Testosterone?

Tongkat Ali comes from the roots of the plant Eurycoma longifolia, which grows primarily in Malaysia, Indonesia, and Thailand. Traditionally, the plant was used as a natural remedy for fatigue, sexual health, and physical performance.

Modern supplement science has focused on Tongkat Ali because of its potential influence on testosterone production and hormone balance.

The way it works is interesting.

Tongkat Ali doesn’t directly inject testosterone into your system the way testosterone replacement therapy does. Instead, it works by influencing the body’s hormonal environment, helping the body maintain healthier testosterone production.

Several mechanisms appear to be involved.

First, Tongkat Ali may reduce levels of cortisol, the body’s primary stress hormone. High cortisol is strongly associated with reduced testosterone levels, especially in people who train intensely or live under constant stress.

Second, Tongkat Ali may increase the amount of free testosterone in circulation. Testosterone in the body often binds to a protein called SHBG (sex hormone binding globulin), which essentially locks it away and makes it inactive. Some research suggests Tongkat Ali can reduce SHBG binding, leaving more testosterone available for the body to use.

Third, Tongkat Ali appears to influence luteinising hormone (LH) activity, which is part of the hormonal signalling system that tells the testes to produce testosterone.

Because of these effects, Tongkat Ali is often included in testosterone-support supplements designed to optimise hormone health rather than artificially replace it.

But supplements are rarely a single-ingredient solution.

Hormone health is heavily influenced by micronutrients, lifestyle, recovery, and overall metabolic health. Nutrients like vitamin D, zinc, and magnesium are particularly important for maintaining healthy testosterone levels.

That’s why many people combine herbal support like Tongkat Ali with broader nutritional support. For example, something like Applied Nutrition Testosterone Support TRT 300g includes multiple ingredients aimed at supporting hormone balance, stress management, and overall vitality rather than relying on a single compound alone.

The key takeaway here is that Tongkat Ali isn’t magic — but it may help create a biological environment where testosterone production can function more effectively.

2. Does Tongkat Ali Actually Raise Testosterone Levels?

This is the question most people care about.

Does Tongkat Ali actually increase testosterone?

The answer is: sometimes — particularly when testosterone levels are already suppressed.

Several clinical studies have explored this.

One frequently cited study examined men with low testosterone levels who supplemented with Tongkat Ali for several weeks. The results showed a significant increase in testosterone levels and improvements in symptoms like fatigue and libido.

Another study looked at men experiencing stress-related hormonal imbalance. After several weeks of Tongkat Ali supplementation, participants experienced reductions in cortisol and improvements in testosterone balance.

The important detail here is context.

Tongkat Ali tends to work best in people who have room for improvement. If testosterone levels are already optimal, increases may be smaller or less noticeable. But in individuals dealing with stress, fatigue, poor recovery, or mild hormonal suppression, the benefits can be more meaningful.

Athletes sometimes notice changes in areas like:

• energy levels
• training motivation
• recovery capacity
• libido and mood

However, Tongkat Ali should never be viewed as a replacement for the fundamentals of hormone health.

Sleep quality, resistance training, body fat levels, and nutrient intake all play a massive role in testosterone production. Even small deficiencies can suppress hormone levels.

For example, vitamin D plays a major role in testosterone regulation. Many people in the UK are chronically low in vitamin D due to limited sun exposure. Supplements like Applied Nutrition Vitality Vitamin D3 are often used to support healthy hormone levels because vitamin D functions almost like a hormone itself within the body.

So while Tongkat Ali may help, it tends to work best when combined with the broader lifestyle factors that support hormonal health.

3. How Quickly Does Tongkat Ali Start Working?

Many supplements promise dramatic changes within days, but hormone-related supplements typically take a little longer to show noticeable effects.

For Tongkat Ali, most research suggests measurable changes can appear within 2 to 4 weeks of consistent supplementation.

However, the timeline can vary depending on several factors.

First, the quality and concentration of the extract matters. Tongkat Ali supplements often come standardised to specific active compounds, and stronger extracts may produce faster results.

Second, individual hormone levels make a difference. Someone who already has healthy testosterone levels may notice subtle improvements rather than dramatic changes.

Third, lifestyle factors play a major role.

Training intensity, sleep quality, calorie intake, and stress levels all influence hormone production. If someone is sleeping poorly or constantly overtraining, Tongkat Ali alone won’t fix the underlying problem.

Many people report noticing improvements in energy and mental drive first, followed by performance benefits over time.

Training performance itself can also influence testosterone production. Strength training stimulates hormone responses that support muscle growth and recovery. That’s one reason supplements supporting performance — like Naughty Boy Prime Creatine — are often part of the broader strategy around strength and hormone optimisation.

Creatine doesn’t directly boost testosterone, but by improving strength output and training intensity, it can support the kind of training environment that encourages healthy hormone function.

In other words, supplements often work best when they’re supporting the overall system rather than acting alone.

4. What Does the Research Say About Tongkat Ali and Testosterone?

Tongkat Ali has gained attention partly because it has a growing body of scientific research behind it.

While not every study shows dramatic effects, several well-designed studies have produced encouraging results.

One study published in the Journal of the International Society of Sports Nutrition examined men supplementing with Tongkat Ali while following a training program. Participants showed improvements in body composition and increases in testosterone compared to the control group.

Another study found that Tongkat Ali supplementation helped reduce cortisol while improving testosterone levels in individuals experiencing stress.

This cortisol connection is particularly important.

Cortisol and testosterone often operate in opposition to each other. When cortisol rises due to stress, sleep deprivation, or excessive training, testosterone production can drop.

By helping moderate cortisol levels, Tongkat Ali may indirectly support healthier testosterone balance.

There’s also some evidence suggesting Tongkat Ali may improve sexual health markers, which has traditionally been one of the plant’s primary uses in herbal medicine.

That said, it’s important to keep expectations realistic.

Natural supplements rarely produce the same dramatic hormonal changes seen with pharmaceutical treatments. Instead, they tend to support gradual improvements in hormone balance over time.

Other nutrients also play supporting roles in testosterone regulation.

For instance, healthy fat intake and omega-3 fatty acids contribute to hormonal signalling and metabolic health. That’s why supplements like Per4m Advanced Omega 3 are often included in broader wellness routines aimed at supporting recovery, cardiovascular health, and hormone balance.

The bigger picture is that hormone health rarely depends on a single supplement.

It’s the combination of training, nutrition, stress management, and micronutrients that ultimately determines how well the endocrine system functions.

5. Can Tongkat Ali Improve Energy, Strength, or Libido?

Beyond testosterone levels themselves, many people take Tongkat Ali because of its potential impact on energy, motivation, and overall vitality.

Testosterone influences multiple systems within the body, including:

• muscle protein synthesis
• nervous system function
• mood regulation
• sexual health

Because of this, even small improvements in hormone balance can sometimes translate into noticeable improvements in daily life.

One of the most commonly reported benefits is improved energy levels. This may be related to Tongkat Ali’s ability to reduce cortisol, as chronic stress is one of the biggest contributors to fatigue.

Some users also report improved training motivation and gym performance. While Tongkat Ali itself is not a stimulant, improved hormonal balance can influence recovery and drive.

Libido improvements are another area where Tongkat Ali has traditionally been used, and several studies support its potential role in supporting sexual health.

However, energy and performance also rely heavily on hydration and electrolyte balance.

Even mild dehydration can reduce workout performance, increase fatigue, and impair recovery. That’s why hydration products like Applied Nutrition Hydration Powder – 240g are often used by athletes looking to support endurance, training performance, and recovery.

When hydration, recovery, and hormone health are all working together, the body is better positioned to maintain strong energy levels and performance both inside and outside the gym.

So far we’ve covered:

What Tongkat Ali is and how it may influence testosterone
Whether it actually increases testosterone levels
How quickly it can start working
What scientific research says about the supplement
How it may affect energy, strength, and libido

In Part 2, we’ll explore the remaining questions people often ask about Tongkat Ali, including:

• whether it’s safer than TRT
• potential side effects
• whether it can be taken daily
• how it works alongside other testosterone supplements
• and who benefits most from using it.

Part 2 6. Is Tongkat Ali Safer Than Testosterone Replacement Therapy (TRT)?

Testosterone Replacement Therapy (TRT) is a medical treatment designed to restore testosterone levels in men who have clinically low hormone levels. It can be highly effective when prescribed and monitored by a doctor, but it also carries potential risks and long-term commitments.

This is one of the reasons many people look toward natural testosterone-support supplements before considering medical treatment.

Tongkat Ali is often positioned as a natural alternative because it works differently from TRT. Instead of replacing testosterone with synthetic hormones, Tongkat Ali aims to support the body’s own hormone production mechanisms.

TRT introduces external testosterone into the body. This can raise hormone levels quickly, but it also suppresses the body’s natural testosterone production over time.

Tongkat Ali, by contrast, works more subtly. Its potential benefits come from supporting hormonal balance, reducing stress hormones like cortisol, and improving the body’s natural testosterone signalling.

Because of this difference, Tongkat Ali is generally considered lower risk for healthy individuals compared with hormone therapy. However, it’s important to understand that the two options serve very different purposes.

TRT is designed for medical testosterone deficiency, while supplements are intended to support overall hormone health.

Supplements that combine multiple supportive ingredients are often used alongside lifestyle improvements. For example, products like Applied Nutrition Testosterone Support TRT 300g combine vitamins, minerals, and herbal ingredients designed to support hormone balance, energy levels, and overall male vitality.

This kind of approach focuses on optimising natural hormone production rather than replacing it.

7. Are There Any Side Effects of Taking Tongkat Ali?

Tongkat Ali is generally considered safe for most healthy adults when used in appropriate doses.

Most studies examining Tongkat Ali supplementation report minimal side effects, particularly when standardised extracts are used.

However, like many supplements that influence hormones and energy levels, some individuals may experience mild effects such as:

• restlessness
• difficulty sleeping if taken late in the day
• mild irritability in sensitive individuals

These effects are relatively uncommon and often related to dose or timing.

Taking Tongkat Ali earlier in the day can help reduce the chance of sleep disruption, especially for people sensitive to stimulatory herbs.

It’s also important to remember that the supplement industry includes products with widely varying quality levels. Choosing reputable products with well-formulated ingredient profiles is essential.

Beyond herbal ingredients, other nutrients also influence hormonal health and recovery. For example, adequate intake of healthy fats plays a role in hormone production.

Omega-3 fatty acids are often included in broader wellness routines because they support cardiovascular health, recovery, and metabolic function. Supplements like Per4m Advanced Omega 3 provide EPA and DHA, which are important fats involved in numerous biological processes.

While omega-3 fats don’t directly raise testosterone, they contribute to overall health factors that support long-term hormone balance.

8. Can Tongkat Ali Be Taken Daily?

Most Tongkat Ali supplements are designed to be taken daily.

Research suggests consistent supplementation is necessary for the herb’s potential effects to accumulate over time. Unlike stimulants that produce immediate effects, herbal adaptogens typically work through gradual improvements in hormonal balance.

Typical Tongkat Ali protocols involve daily use for several weeks before evaluating results.

Many users run cycles lasting four to eight weeks, followed by a short break. This isn’t always necessary, but some people prefer cycling herbal supplements to maintain sensitivity.

Daily supplementation works best when combined with strong lifestyle habits that support hormone health.

These include:

• resistance training
• adequate sleep
• stress management
• sufficient calorie intake
• proper hydration

Training performance itself plays a role in hormone regulation. Strength training stimulates testosterone responses that support muscle growth and recovery.

Supplements that support high-intensity training can therefore complement hormone optimisation strategies.

For example, Naughty Boy Prime Creatine supports muscular energy production and strength output, helping athletes maintain higher training intensity and performance over time.

Creatine doesn’t directly increase testosterone, but the training improvements it supports can contribute to an environment where healthy hormone function is maintained.

9. Can You Take Tongkat Ali With Zinc or Other Testosterone Supplements?

Yes — Tongkat Ali is often combined with other nutrients that support testosterone production.

Zinc, magnesium, vitamin D, and certain herbal extracts all play roles in hormone regulation.

Because testosterone production depends on multiple biological systems, combining supportive nutrients can sometimes produce better results than relying on a single ingredient.

Zinc and magnesium are especially important because deficiencies in these minerals are associated with reduced testosterone levels.

Vitamin D is another major factor in hormone health. Many people living in northern climates have low vitamin D levels due to limited sun exposure, particularly during winter months.

Supplementing with vitamin D can help support hormonal balance and overall health. Products like Applied Nutrition Vitality Vitamin D3 are commonly used to support normal vitamin D levels, which in turn contribute to healthy testosterone production.

When these nutrients are combined with lifestyle improvements such as resistance training, sleep optimisation, and stress management, the body has the resources it needs to maintain strong hormone function.

10. Who Benefits Most From Tongkat Ali Supplementation?

Tongkat Ali tends to be most useful for individuals experiencing lifestyle factors that suppress testosterone levels.

These include:

• chronic stress
• poor sleep
• high training loads
• calorie deficits during dieting
• aging-related hormonal decline

In these situations, hormone balance can become disrupted. Stress hormones rise, recovery slows, and energy levels drop.

Tongkat Ali may help support hormone balance during these periods by helping regulate cortisol and supporting natural testosterone production.

Athletes, in particular, sometimes use Tongkat Ali during demanding training phases when physical stress is high.

However, it’s important to remember that supplements are only one piece of the puzzle.

Hormone health ultimately depends on the broader lifestyle environment — including sleep, nutrition, hydration, and training quality.

Hydration, for example, plays a surprisingly important role in energy levels and training performance. Even mild dehydration can impair physical performance and increase fatigue.

That’s why many athletes prioritise hydration strategies alongside supplementation. Products like Applied Nutrition Hydration Powder – 240g provide electrolytes that help maintain fluid balance during intense training sessions.

When hydration, recovery, nutrition, and hormone support strategies work together, the body is far better equipped to maintain consistent energy, strength, and overall performance.
