Short answer: what's the difference?
Shilajit and Tongkat Ali are two of the most popular natural supplements for energy, vitality and hormone balance – but they work in different ways. Tongkat Ali is a root extract with the strongest scientific support for supporting testosterone levels and stress management in men. Shilajit is a mineral-rich, fulvic-acid-based substance from the Himalayas that has traditionally been used as a broad adaptogen for energy, recovery and cellular vitality, but with less human research behind it. Many choose one, the other – or combine both.
What is Shilajit?
Shilajit is a dark, tar-like substance formed from plant material compressed in the cracks of the Himalayan mountains over a very long time. It contains fulvic acid and a broad spectrum of minerals, and has been used in traditional Ayurvedic medicine for centuries as a general strengthening adaptogen.
What is Tongkat Ali?
Tongkat Ali (Eurycoma longifolia) is a root extract from Southeast Asia that has traditionally been used to support energy, male vitality and hormone balance. It is one of the more researched natural supplements on the market, with clinical studies that have looked specifically at free testosterone, cortisol and subjective energy/mood.
The research picture – how does the evidence differ?
This is the most important difference between the two substances:
- Tongkat Ali has several clinical studies in humans showing effects on free testosterone, cortisol levels and perceived energy, especially in men with initially low levels.
- Shilajit has promising results in smaller studies and animal studies around energy, oxidative stress and fertility markers, but there are significantly fewer and less controlled human studies than for Tongkat Ali.
That doesn't mean Shilajit lacks effect – but if you want the strongest scientific basis specifically for testosterone and stress management, Tongkat Ali is today the better-documented choice.
Dosage and form
Tongkat Ali is most often sold as a standardized extract in capsule form, where dosage and extract strength (e.g. 100:1 or 200:1) are clearly stated – making it easier to compare products and dose consistently. Shilajit comes both as purified resin and as capsules; purity and processing vary more between manufacturers, which makes product selection extra important.
Can you combine Shilajit and Tongkat Ali?
Yes. Since they work through partly different pathways – Tongkat Ali more hormonally targeted, Shilajit more broadly mineral- and energy-supporting – many choose to combine them. Start with one supplement at a time for 4–6 weeks so you can evaluate the effect before possibly adding the other.
Which should you choose?
Use this as a simple guide based on your main goal:
- Want to support testosterone, stress management and training recovery with the strongest research support? Start with Tongkat Ali.
- Want a broad mineral supplement for general energy and vitality, and don't mind that the evidence is thinner? Shilajit may be worth trying.
- Unsure? Tongkat Ali is the safer first choice given the current research – see our complete guide to Tongkat Ali for dosage and quality selection.
Safety
Both supplements should be avoided during pregnancy and breastfeeding, by people under 18, and by people with hormone-sensitive conditions without first consulting a doctor. Always choose purified Shilajit from a reputable supplier – impure resin can contain heavy metals. Consult a healthcare professional if you take medication or have an underlying condition.
Frequently Asked Questions
Is Shilajit or Tongkat Ali stronger?
They aren't measured on the same scale. Tongkat Ali has stronger clinical support specifically for testosterone and cortisol. Shilajit is broader in its traditional use but less researched.
Can I take them at the same time?
Yes, but introduce one at a time so you can evaluate the effect of each supplement separately.
Which is best for training and recovery?
Many choose Tongkat Ali for training-related recovery and hormone balance – read more in our guide to the best testoboosters 2026.
