More than half of adults worldwide report feeling tired or foggy at some point in their day, and many of us have tried every trick in the book like green tea, naps, even talking to our plants. According to research published in the Journal of the International Society of Sports Nutrition, certain herbal extracts actually seem to influence stress hormones and mood in adults with moderate stress levels, suggesting that some old-school remedies might not be just placebo hype.
If you’ve ever scrolled through health forums or wandered down the supplement aisle wondering which “natural testosterone booster” actually works, you’ve probably seen Tongkat Ali mentioned more times than cat videos on the internet. This Southeast Asian root extract (from the plant Eurycoma longifolia) is touted for everything from boosting energy to helping mood. One branded version is Tongkat Ali, marketed as a male vitality enhancer. But behind the hype lies a mix of science, tradition, and a few unanswered questions.
What Tongkat Ali Is and How It May Affect the Body
For centuries, traditional healers in Malaysia and Indonesia have used the roots of Eurycoma longifolia as a general health tonic. In modern research, scientists have focused on how this plant affects hormone balance, particularly testosterone and cortisol (two hormones tied to stress, energy, and physical performance).
An article published in PUBMed Central (PMC) suggests that standardized extracts can lower cortisol while increasing testosterone levels, at least in adults under stress. One four-week trial found participants taking a standardized extract experienced a 37% increase in testosterone and a 16% decrease in cortisol compared to placebo. Lower cortisol and higher testosterone were linked to better mood, like feeling less tense and more focused – basically, less “I need another coffee” and more “I’ve got this.”
That said, not every study shows miracles. Another research published in MDPI Applied Sciences in 2024 shows that in trained men and women, no significant changes in testosterone or muscle composition have been seen. In other words, if you’re already in good hormonal shape, don’t expect Tongkat Ali to turn you into a superhero overnight. Your mileage may vary.
Who Might Benefit Most and Who Should Avoid It
People with naturally low testosterone or under moderate stress may see the most noticeable benefits. Aging men or anyone feeling drained might experience improvements in energy and mood. For those curious about additional ways to boost testosterone naturally, several other supplements and lifestyle approaches can complement Tongkat Ali.

On the flip side, some groups should give this root a pass. Pregnant or breastfeeding individuals, children, and people with hormone-sensitive conditions (like prostate cancer) should avoid it. In Clinicians also advise caution for those with liver disease, heart conditions, or complex medication routines because herbal supplements can sometimes play unwanted mix-and-match games with prescriptions.

Potential Side Effects and Safety Profile
Even with a long history of use, Tongkat Ali isn’t completely side-effect-free. Mild issues like restlessness, sleepless nights, or a grumbly stomach can happen. Think of it like coffee: helpful in moderation, annoying in excess. Low-quality or contaminated products could even stress the liver. (source: Verywell Health, 2023 and Health Insiders, 2023)
Supplements are tools, not magic wands. They work best when paired with decent sleep, balanced meals, and a bit of exercise. Sorry, no pill replaces a good night’s rest or skipping the vending machine.
Choosing a High-Quality Product
Because supplements aren’t regulated like prescription drugs, quality varies. Look for transparent labels, third-party testing, and clear standardization. Products that list bioactive markers like eurypeptides or eurycomanone and provide batch certificates are safer bets. Aim for doses similar to those in studies (roughly 200 to 400 milligrams per day) for four to twelve weeks. Taking more doesn’t necessarily give better results and may increase side effects.
Conclusion
Tongkat Ali isn’t just a catchy name on a supplement bottle. The research suggests it may support hormone balance in people with low testosterone or higher stress, potentially improving mood and energy. But results vary, and benefits aren’t guaranteed. The bottom line: use it thoughtfully, in studied doses, and as a complement to healthy eating, exercise, and sleep. Always check with a healthcare provider first. When used responsibly, Tongkat Ali can be a helpful addition to your wellness toolkit, but it’s no magic bullet.
