Shilajit and Testosterone: What the Research Actually Shows (2026 UK Guide)

Last updated: November 2026

🧪 Independently Lab-Tested · ☪️ Halal Certified · 🏔️ Pure Himalayan Sourced · 🇬🇧 UK Formulated

⚡ Quick answer: One clinical trial found that 250mg of purified shilajit twice a day for 90 days raised total testosterone, free testosterone and DHEAS in healthy men aged 45 to 55, compared with placebo. It's one study with 75 men, and it hasn't been widely repeated. UK law doesn't allow supplement brands to claim shilajit "increases testosterone".

Lots of pages promise dramatic hormone boosts. This one gives you the real study, the real numbers, what UK law says, and where the evidence is strong or weak.

📋 Key Takeaways

• One randomised, double-blind, placebo-controlled trial (Pandit et al., 2016) found significant rises in total testosterone, free testosterone and DHEAS after 90 days of purified shilajit. The men were healthy, not diagnosed with low testosterone.
• "Increases testosterone" is not an authorised health claim in the UK, so no food supplement can legally advertise it.
• The evidence is real but narrow: one main human trial, a modest sample, and no independent repeat yet.
• Ongoing low-testosterone symptoms need a GP and a blood test, not a supplement.
• If you try shilajit, purity matters most. Unpurified shilajit can contain heavy metals, so independent lab testing is essential.

1. 🔗 Why Shilajit and Testosterone Are Linked

Shilajit is a mineral-rich resin that seeps from rock in mountain ranges like the Himalayas. It's been used in Ayurveda for general vitality for centuries. Its main components are fulvic acid and 85+ trace minerals, which we explain in our Fulvic Acid guide and Shilajit Benefits guide.

The testosterone link comes from one real, published clinical trial. That trial gets quoted, and often oversimplified, all over the supplement industry. Here's what it actually found.

Important: shilajit is sold in the UK as a food supplement, not a medicine. It isn't intended to diagnose, treat, cure or prevent any disease, including low testosterone (hypogonadism). This article isn't medical advice. If you're worried about your testosterone, speak to your GP.

2. 🔬 What the Research Shows

The main study is Pandit et al. (2016), "Clinical evaluation of purified Shilajit on testosterone levels in healthy volunteers," published in the peer-reviewed journal Andrologia.

By supplement-research standards, that's a well-designed trial. Neither the men nor the researchers knew who got shilajit, which makes the result more reliable than an open study. The stable LH and FSH levels are also a good sign.

But one trial is still one trial. Good science needs results repeated by other teams, and that hasn't happened yet.

3. ⚖️ What UK Law Allows Brands to Claim

Most shilajit sellers skip this part.

Under rules enforced by the Advertising Standards Authority (ASA) and the Committee of Advertising Practice (CAP), food supplements can only use health claims listed on the official Great Britain Nutrition and Health Claims Register. Testosterone isn't an authorised claim for shilajit or fulvic acid. Claims like "increases testosterone" or "boosts your hormones" aren't allowed, and "treats low T" counts as a medicinal claim.

In practice:

• A UK shilajit brand that follows the rules can't advertise that its product raises testosterone, even when it cites a real study.
• A brand that does make that claim is showing you a compliance red flag, not a stronger product.
• Reporting what a published study found, as this article does, is different from promising a result. We can tell you what the study found. We can't tell you our resin or gummies will do the same for you.

4. 🧬 What Might Explain the Effect

The trial didn't explain why testosterone rose. Researchers have suggested a few possible reasons:

• Antioxidant activity. Fulvic acid neutralises free radicals in lab studies, and oxidative stress is one factor linked to age-related hormone decline.
• Cell energy. Some research suggests shilajit may support mitochondria, the energy centres of cells, including the cells that make testosterone.
• Trace minerals. Shilajit naturally contains zinc and magnesium, which play a normal role in hormone metabolism as part of a balanced diet.

These are reasonable ideas, not proven explanations.

5. 🚧 Limits of the Evidence

• There's one main human trial. A finding needs repeating by independent teams before it's well established.
• The sample was small. 75 men is fine for an early trial but too few to rule out chance or individual differences.
• The men were healthy. The trial didn't test men with diagnosed low testosterone, so it says nothing about treating it.
• It was one group in one setting. Results may differ by age, health and background.
• Funding is worth noting. Much botanical supplement research is funded by manufacturers, which is worth bearing in mind with any single result.

None of this means the finding is wrong. It means it's early.

What about sperm count and strength? Testosterone isn't the only thing researchers have measured in men. For the fertility and muscle-strength studies, and safe dosage for men, see our Shilajit for Men guide.

What about ashwagandha? Ashwagandha has also been studied for testosterone in men, across more trials than shilajit, though the results are still modest and it's currently under a UK safety review. We compare the two honestly in Shilajit vs Ashwagandha: Differences, Evidence and Safety.

6. 🩺 Signs of Low Testosterone and When to See Your GP

If you're here because you're worried about your own levels, this section matters most.

Common signs of low testosterone include ongoing tiredness, low sex drive, erection problems, loss of muscle, low mood, low motivation and more body fat. Many other conditions cause the same symptoms, so you can't diagnose it yourself.

If these symptoms keep going, see your GP. They can arrange a morning blood test, usually between 7 and 11am because testosterone changes through the day, and discuss treatment if you need it. No food supplement treats diagnosed low testosterone.

7. 🧪 Why Purity Matters Most

PEAKSPURITY Resin lab certificate

PEAKSPURITY Gummies lab certificate

Whatever you think of the testosterone research, this part isn't up for debate. Shilajit comes from mountain rock, and unpurified or untested shilajit can contain heavy metals. Before you buy, check for:

• independent lab testing for lead, arsenic, mercury and cadmium
• a certificate of analysis (COA) you can see or request
• a clear purification process, not just "raw" or "natural"
• traceable sourcing

PEAKSPURITY Resin and Gummies are independently tested by Eurofins and a US-based lab. No batch goes on sale until it passes.

9. 🚫 Common Myths

"The study proves shilajit will raise my testosterone." It found an average effect across 38 men in one trial. A group average isn't a personal guarantee.

"More expensive shilajit has a bigger effect." Price usually reflects format, sourcing and testing, not a proven stronger hormone effect.

"It's natural, so it's fine to take with TRT." If you're on testosterone replacement therapy or any hormone medication, speak to your GP or specialist before adding any supplement.

"'Clinically proven to boost testosterone' means a brand is trustworthy." In the UK, that wording is a compliance red flag, not a sign of credibility.

10. ❓ Frequently Asked Questions

Does shilajit increase testosterone?

One randomised, double-blind, placebo-controlled trial found significant rises in total testosterone, free testosterone and DHEAS in healthy men aged 45 to 55 after 90 days. It's a single trial with a modest sample, so treat it as promising early evidence, not a guaranteed result.

How much shilajit was used in the testosterone study?

250mg of purified shilajit twice a day, so 500mg a day in total, for 90 days.

How long does shilajit take to work?

The trial measured results after 90 days. In general, any effects from shilajit build slowly with daily use over several weeks, and results vary from person to person.

Can PEAKSPURITY say its products increase testosterone?

No. UK advertising rules don't allow food supplements to claim they increase testosterone. We can report on published research without making that claim about our products.

Is shilajit a substitute for TRT?

No. Shilajit is a food supplement, not a medicine, and it doesn't replace treatment for diagnosed low testosterone. Speak to your GP about treatment options.

Were there side effects in the study?

Published reports on the trial didn't identify significant side effects in the shilajit group over 90 days. Individual tolerance varies, and the general safety advice in our Shilajit Benefits guide still applies.

Should I take shilajit to raise my testosterone?

That's a decision to make with your GP, especially if you have symptoms of low testosterone. A blood test and medical advice are a better starting point than a marketing claim.

Does shilajit affect testosterone in women?

The trial only included men, so there's no testosterone data for women. Read our Shilajit for Women guide for what the research says.

11. ✅ Final Verdict

The shilajit and testosterone research is stronger than most supplement claims. A randomised, placebo-controlled trial with a significant result is a higher bar than many botanical ingredients reach. But it's still one trial, in one group, and UK law is clear that no supplement, including ours, can be sold as a testosterone booster.

If you're curious about shilajit, focus on purity and testing over the testosterone headline. If you have symptoms of low testosterone, start with your GP and a blood test.
