Is Tongkat Ali like a steroid? A deep dive into the science behind the supplement

5 min read

Despite being used in traditional Southeast Asian medicine for centuries, many still question the true nature and effects of the herbal supplement Tongkat Ali. The central question for many in the fitness and wellness communities is: Is Tongkat Ali like a steroid?

Quick Summary

This article explains that Tongkat Ali is a natural herb and not an anabolic steroid. It works by stimulating endogenous testosterone production and reducing cortisol, a mechanism fundamentally different from synthetic anabolic agents.

Key Points

  • Not an Anabolic Steroid: Tongkat Ali is a natural herbal supplement, while steroids are synthetic hormones that directly mimic testosterone.

  • Supports Natural Production: Tongkat Ali works by stimulating the body's endogenous testosterone production rather than introducing it synthetically.

  • Frees Bound Testosterone: The supplement helps increase levels of 'free' testosterone by reducing Sex Hormone-Binding Globulin (SHBG).

  • Reduces Stress: As an adaptogen, Tongkat Ali helps lower the stress hormone cortisol, which can have a positive effect on the testosterone/cortisol ratio.

  • Gradual Effects: The benefits of Tongkat Ali appear gradually over weeks or months, unlike the rapid and intense effects of anabolic steroids.

  • Safer Profile: Tongkat Ali has a generally safer side-effect profile than steroids, though product quality and potential medication interactions should be considered.

  • Supports Normal Levels: Tongkat Ali is most effective at restoring normal testosterone levels in individuals with existing deficiencies, rather than drastically boosting them in healthy individuals.

Tongkat Ali vs. Anabolic Steroids: A Fundamental Difference

Tongkat Ali, also known as Longjack or Eurycoma longifolia, is a far cry from an anabolic steroid. Anabolic-androgenic steroids (AAS) are synthetic, or man-made, versions of the male hormone testosterone. They are designed to mimic testosterone's powerful anabolic (muscle-building) and androgenic (masculinizing) effects by directly binding to androgen receptors in the body. This can lead to rapid and significant changes in muscle mass, strength, and other physiological processes, often with a range of dangerous side effects.

Tongkat Ali, on the other hand, is a herbal supplement that works with the body's natural systems rather than overpowering them. The key difference lies in the mechanism of action. While steroids introduce a large, external dose of synthetic hormones, Tongkat Ali's active compounds, such as quassinoids and eurypeptides, support the body's own hormone production. Specifically, it has been shown to increase the release of luteinizing hormone (LH), which signals the testicles to produce more testosterone. It also helps free up existing testosterone that is bound to sex hormone-binding globulin (SHBG). By managing the body's existing hormonal landscape, Tongkat Ali aims to restore and maintain normal, healthy testosterone levels, especially in individuals with low levels.

How Tongkat Ali Works: The Hormonal Pathway

The root of Tongkat Ali contains bioactive compounds that influence the body's hormonal system. These include:

  • Quassinoids (eurycomanone): These are the primary active ingredients believed to be responsible for Tongkat Ali's therapeutic effects, including its ability to support testosterone levels.
  • Eurypeptides: These small peptides are thought to activate the enzyme CYP17, which is involved in the synthesis of testosterone from other hormones.

In men, Tongkat Ali supports testosterone levels through a few key pathways:

  1. Stimulates LH: It encourages the pituitary gland to release Luteinizing Hormone (LH). LH then travels to the testes, signaling them to increase testosterone production.
  2. Reduces SHBG: It helps decrease Sex Hormone-Binding Globulin (SHBG). SHBG binds to testosterone, making it inactive. By reducing SHBG, Tongkat Ali increases the amount of 'free' testosterone available for the body to use.
  3. Lowers Cortisol: It acts as an adaptogen, helping the body manage stress by lowering levels of the stress hormone cortisol. High cortisol can suppress testosterone, so reducing it helps create a more favorable hormonal environment for testosterone production.

The Role of an Adaptogen

Unlike steroids, which force a specific outcome, Tongkat Ali is best described as an adaptogen. This means it helps the body adapt to stressors and maintain hormonal balance. This has been particularly beneficial for individuals with moderately high stress levels, where supplementation has been shown to improve mood and reduce anxiety. This adaptive and restorative action is fundamentally different from the direct, systemic manipulation of hormone levels seen with steroids.

The Benefits and Scientific Evidence for Tongkat Ali

While not a substitute for medical treatment, Tongkat Ali has a range of studied benefits. It is important to note that many studies are small or short-term, and results can be mixed depending on the population and dosage.

Testosterone Support: Studies have shown that Tongkat Ali can significantly increase testosterone levels, particularly in men with low or borderline levels. For instance, a 2012 study in men with late-onset hypogonadism found that a 200mg daily dose for one month returned testosterone levels to normal in over 90% of participants.

Athletic Performance: There is some evidence suggesting Tongkat Ali can aid in athletic performance and muscle growth, especially when combined with training. A 2003 study found that men who took Tongkat Ali during a 5-week strength training program saw significant increases in lean body mass and strength compared to a placebo group. However, results are not always consistent, with a 2024 study finding no significant changes in exercise-trained males and females.

Stress Reduction and Mood: Research shows that Tongkat Ali can help reduce stress hormones. A study in moderately stressed adults found that daily supplementation significantly reduced cortisol levels and improved feelings of tension, anger, and confusion.

Sexual Health and Fertility: Traditionally used as an aphrodisiac, Tongkat Ali has been shown in some studies to improve libido, erectile function, and male fertility, including sperm motility and concentration.

Safety and Risks: A Cautious Approach

While Tongkat Ali is considered relatively safe for short-term use, especially when using standardized water extracts, some risks exist. Key concerns include:

  • Product Quality: The lack of strict FDA regulation means product quality can vary widely. Some products have been found to be contaminated or contain undisclosed substances, including synthetic drugs. Choosing certified, high-quality supplements is crucial.
  • Potential for DNA Damage: A 2021 report by the European Food Safety Authority (EFSA) raised concerns about potential DNA damage at very high doses in lab settings. This risk is not typically associated with standard, recommended dosages in human studies.
  • Interaction with Medications: Tongkat Ali can affect hormone levels and may interact with certain medications, including those for blood pressure, immunosuppressants, and hormone therapy.

It is always wise to consult a healthcare professional before starting any new supplement, particularly if you have underlying health conditions.

Conclusion: The Verdict on Tongkat Ali

To answer the central question, Is Tongkat Ali like a steroid? The clear answer is no. Anabolic steroids are synthetic hormones with powerful, direct, and often dangerous effects on the body. Tongkat Ali is a natural herbal supplement that works indirectly and adaptogenically, supporting the body's own testosterone production and stress response system to restore healthy balance, especially when levels are low. While it may offer benefits for vitality, athletic performance, and hormonal health, its effects are much milder and slower to manifest than steroids. The distinction is crucial for anyone seeking to improve their health and performance safely and naturally. The science supports Tongkat Ali as a health supplement, not a synthetic powerhouse.

Frequently Asked Questions

While Tongkat Ali is not explicitly on the World Anti-Doping Agency (WADA) list, its testosterone-boosting potential means it could fall under the category of substances with 'similar biological effects' to anabolic agents. Athletes should exercise caution and consult with anti-doping authorities.

The effects of Tongkat Ali are not immediate. Most studies report that noticeable improvements in testosterone levels, mood, or energy can be seen after a few weeks to several months of consistent daily supplementation, especially in those with low baseline levels.

Most research on Tongkat Ali has been conducted on men. While some studies suggest it may help with stress or energy in women, research is limited. Due to its potential effect on hormones, it is best for women to consult a healthcare provider before use.

Common side effects are usually mild and may include insomnia, restlessness, and anxiety, often associated with its energy-boosting effects. Some digestive issues have also been reported. Rare cases of liver injury have been reported, often linked to contaminated or high-dose products.

The long-term safety of Tongkat Ali has not been well-documented in humans. While short-term studies show it is well-tolerated, limited research and concerns about high-dose extracts warrant a cautious approach, and consultation with a doctor is recommended for long-term use.

No. Unlike anabolic steroids, Tongkat Ali does not directly build muscle. Any potential muscle growth is a secondary effect of its action in restoring and maintaining healthy testosterone levels, which can aid in muscle protein synthesis, especially when combined with resistance training.

Because dietary supplements are not strictly regulated, product quality can be inconsistent. Some low-quality products may contain fillers, inaccurate doses, or even be 'spiked' with illegal substances. Choosing a reputable brand that provides standardized, lab-tested extracts minimizes risk and ensures efficacy.
