Unlocking the Health Benefits of Shilajit: What Science Says
Search for shilajit online and you'll find some huge promises. Miracle this, ancient secret that. Plenty of it quotes "studies" without ever linking to one.
This post does something different. Every study we mention is real and linked, so you can read it yourself. We'll cover what's in shilajit, what the research says about its potential benefits for energy, cognitive function, immune health and inflammation, and how to tell a strong study from a weak one.
If you'd rather skip straight to the product, here's our lab tested Himalayan resin.
What is actually in shilajit?
Start with the stuff you can measure. Shilajit is a resin that forms over centuries from plant matter trapped in mountain rock. (We explain how in The Ancient Secrets of Shilajit.)
Chemically, most of it is made up of:
- Fulvic acid. The main compound in shilajit, and the one most people talk about. It's a type of humic substance, formed when organic matter breaks down.
- Humic acid. A close relative of fulvic acid. Together, fulvic and humic acid are called total humic substances.
- Dibenzo-alpha-pyrones. A group of organic compounds found in shilajit that researchers often measure.
- Naturally occurring minerals. Picked up from the rock the resin forms in.
How much of each you get depends on the batch. That's why the number on a lab certificate matters far more than a number on a label.
Our February 2026 batch was tested by Huson and Hardwick (Alex Stewart Agriculture), an ISO 17025 accredited lab in Liverpool. It came back at 73.8% fulvic acid and 88.5% total humic substances, with heavy metals within limits and no E. coli, salmonella or pesticides detected. The full certificate is here (PDF) and everything else is on our Lab Results page.
What does the research say about shilajit's health benefits?
There are published papers on shilajit going back decades. Some are lab studies, some are on animals and a few are human trials. Here's what they've found in the four areas people ask about most.
1. Energy levels
The best-known human trial is from the University of Nebraska, published in 2019 in the Journal of the International Society of Sports Nutrition. 63 recreationally active men took either a placebo, 250mg or 500mg of shilajit a day for 8 weeks. Then they did a tiring leg exercise test.
The 500mg group held on to more of their strength. Their strength dropped by about 9% after the test, compared with about 16% in the placebo group. That's roughly the same amount as one pea-sized serving of our resin, though the trial used a standardised extract rather than resin. (Read the study.)
A 2012 study in rats, published in the Journal of Ethnopharmacology, looked at energy at the level of the cell. Rats put under chronic stress showed a drop in mitochondrial activity, the process cells use to produce energy. Shilajit brought that activity back towards normal. (Read the study.)
2. Cognitive function
A 2012 review by researchers in Chile looked at shilajit's potential to support cognitive function. It highlights fulvic acid, the main compound in shilajit, which in lab studies stopped tau, a protein linked with brain ageing, from clumping together. (Read the review.)
An earlier study from Banaras Hindu University, published in 1992, tested shilajit in rats. It found improvements in memory and learning tasks. (Read the study.)
3. Immune health
A major 2011 review in the Journal of Ethnopharmacology pulled together decades of research on shilajit. It reports that fulvic acid, shilajit's main compound, has shown a positive effect on immune function in studies. (Read the review.)
4. Inflammation
The same 2011 review links many of shilajit's traditional uses to its anti-inflammatory and antioxidant effects. The 2012 rat study above backs this up at the cell level: shilajit raised the cells' own antioxidant defences and reduced lipid peroxidation, a marker of cell damage.
How to read a shilajit study
Not every study you see quoted online is as solid as it sounds. When a website mentions research, ask these questions:
- Was it done on people, animals or cells? All three are useful, but human trials carry the most weight.
- How many people took part? Bigger trials, repeated by different teams, count for more.
- What did they take? Many trials use one specific extract. Check how it compares with what you're buying.
- Can you actually read it? If a site says "studies show" and doesn't link to one, be careful.
What we can tell you for certain
Here's what we can back up with evidence:
- Where it's from. The Nepal Himalayas, harvested above 16,000ft and sun dried. More in The Journey of Shilajit.
- What's in it. Fulvic acid and total humic substances, measured by an accredited UK lab. See the Lab Results page.
- What's not in it. Heavy metals within limits. No E. coli, salmonella or pesticides detected in our Feb 2026 batch.
- How much you get. A 30g jar holds about 60 servings. A serving is a pea-sized amount, about 500mg.
- How to take it. Dissolve it in warm water, tea or coffee. Full guide in How to Incorporate Shilajit into Your Daily Routine.
Red flags when you're reading about shilajit
A few signs that a claim isn't worth trusting:
- "Clinically proven" for a product that's never been in a trial itself
- A doctor or expert you can't find anywhere else online
- Results that sound too good, too fast
- No lab certificate, or a certificate with no lab name or batch date
The last one is the easiest to check. A real certificate names the lab, the batch, the date and the methods used. If a seller won't show you one, that tells you something.
FAQ
Is there scientific research on shilajit?
Yes. There are lab, animal and a small number of human studies. Most human trials are small and many use one specific extract, so the research is still at an early stage.
What are the potential health benefits of shilajit?
Research has looked at shilajit and energy levels, cognitive function, immune health and inflammation. The strongest human evidence so far is a 2019 trial where 500mg a day helped active men hold on to more strength after tiring exercise. The studies are all linked above.
What is fulvic acid?
Fulvic acid is a natural compound formed when plant matter breaks down. It's the main compound in shilajit resin. Our Feb 2026 batch tested at 73.8%.
How do I know if shilajit is real?
Ask for a lab certificate from a named, accredited lab. Real resin also softens when warm, hardens when cold and dissolves fully in warm water. Our UK Buyer's Guide covers more checks.
Should I talk to my GP before taking shilajit?
If you're pregnant, breastfeeding, under 18, taking medication or have a medical condition, yes. Check with your GP first.

We publish our full lab certificate because we think you should be able to check what you're buying. Our resin is harvested above 16,000ft in Nepal, sun dried, tested in Liverpool and packed in amber glass.
