Shilajit is a sticky, tar-like resinous substance that seeps from cracks in rock in high mountain ranges, most famously the Himalayas. It is thought to form very slowly from plant and microbial matter compressed between layers of rock. It has a long history of traditional use in Ayurvedic practice. No health claim is authorised for it in Great Britain.
Shilajit has become a popular supplement in the UK, and a lot of what is written about it online is either vague or overstated. This article covers what the substance actually is, where it comes from, what the other names for it mean, the difference between raw and purified material, and the forms you will find it sold in. It also covers what a UK seller is and is not permitted to tell you.
What is shilajit made of?
Shilajit is a dense, dark resin. At room temperature it behaves like very thick tar: it holds its shape but slowly deforms under its own weight, and it becomes softer and more pliable when warmed in the hand.
The prevailing view is that it is organic in origin — the long-term product of plant material breaking down under pressure in rock, with microbial activity playing a part. The exact process is not fully settled, and the composition varies from one source region to another, which is one reason it is difficult to describe shilajit in precise numbers.
It is usually discussed alongside humic substances, of which fulvic acid is the most talked-about component. Research into fulvic acid is ongoing and no health claim is currently authorised for it in Great Britain. Any figure quoted for fulvic acid content depends on the source material and the testing method, so treat unsourced percentages with caution and check a product's own analysis.
Where does shilajit come from?
Shilajit is associated with high-altitude mountain regions. The Himalayan range is the best-known source, and material is also collected in the Altai, the Caucasus, the Pamirs, the Tian Shan and other mountain systems across Central and South Asia.
It is not mined in an industrial sense. It is collected by hand from rock faces and crevices, usually in warmer months when the material becomes soft enough to seep out and be scraped away. That collection method has consequences for quality, because whatever is on the rock — dust, grit, plant debris, and whatever minerals are naturally present in the surrounding geology — comes away with it.
This is also why testing matters. A substance that comes out of rock can carry the trace elements of that rock, including heavy metals. Any seller worth buying from will be able to show you the testing for the batch you are being sold.
Why is shilajit called mumijo or mumie?
Different regions have their own name for what appears to be the same or a closely related material. The word shilajit comes from Sanskrit and is the name used in Ayurvedic tradition in India and Nepal.
- Mumijo, mumie or mumiyo — the names used across Russia, Central Asia and the former Soviet states, where the material has its own separate tradition of use.
- Salajeet — the name commonly used in Pakistan.
- Moomiyo and various other transliterations, which are the same word rendered differently in English.
These are not necessarily identical products. Material from different mountain systems, collected and processed differently, is not interchangeable just because the traditions overlap. If a product is described as mumijo rather than shilajit, that tells you something about its likely origin, but it does not tell you anything about its quality on its own.
Purified resin versus raw shilajit
Raw shilajit is the material as it comes off the rock. It contains whatever came with it: rock fragments, sand, plant matter and other debris. It is not a finished food product.
Purification is the step that turns raw material into something intended for consumption. The traditional approach is to dissolve the raw material in water, filter out the insoluble matter, and then evaporate the water off to leave a concentrated resin. Modern producers use the same principle with better filtration and controlled drying. The result is the purified resin sold as a supplement.
Two things follow from this. First, "raw" is not a mark of superiority in this category, whatever the packaging implies — unpurified material is simply unfinished. Second, purification does not remove heavy metals reliably, because dissolved metals stay dissolved. Purification and testing are separate questions, and a product needs both.
What forms is shilajit sold in?
The resin is the traditional form, but it is not the only one, and the right choice mostly comes down to whether you can live with the taste and the handling.
| Form | What it is | Practical notes |
|---|---|---|
| Resin | The purified material itself, sold in a jar | Traditional form. Strong, bitter, earthy taste. Needs measuring out by hand and dissolving in liquid. |
| Capsules | Resin or dried extract in a capsule shell | No taste, portioned for you, easy to travel with. You are relying on the label for how much is in each one. |
| Powder | Dried and ground material | Mixes into drinks. Check whether it is a dried extract or plain dried material, as they are not the same thing. |
| Gummies | Shilajit in a chewable base | The most palatable option. The base contains other ingredients, including sugars or sweeteners, so read the label. |

What can a UK seller claim about shilajit?
Very little, and this is worth understanding before you shop. In Great Britain, health claims made for foods and food supplements have to be authorised and appear on the GB Nutrition and Health Claims Register. There is no authorised health claim for shilajit.
That means no seller in this country may lawfully tell you that shilajit will do anything to your body — not energy, not focus, not recovery, not anything else. What they may do is describe the tradition it comes from, describe the product honestly, and leave the conclusions to you.
So if you see a shop promising you outcomes from shilajit, they are overstepping, and you can reasonably ask what else they are willing to overstate. We have written more about how UK supplement claims rules work if you want the detail.
Common questions
Is shilajit a mineral or a plant product?
Neither label fits neatly. It is generally understood to be organic in origin — derived from plant material over a very long period — but it is collected from rock and carries the trace elements of that rock. It is usually described simply as a resinous substance rather than forced into either category.
Does shilajit go off?
Purified resin is very low in moisture and is stable when kept sealed, cool and dry, away from direct sunlight. It will still carry a best-before date, which you should follow. If it has been left open or exposed to damp, use your judgement.
Is Himalayan shilajit better than Altai shilajit?
There is no good evidence that one region is inherently better than another, and "Himalayan" is used loosely enough in marketing that it is not a reliable signal on its own. What matters more is whether the material has been properly purified and independently tested for the batch you are buying.
Why does shilajit taste so strong?
It is a concentrated resin, and the bitter, smoky, earthy taste is characteristic of the material. It is not a fault. If you find it unmanageable, capsules or gummies avoid the taste entirely.
Why will nobody tell me what shilajit does?
Because in Great Britain nobody lawfully can. No health claim is authorised for it, so any honest UK seller will describe its traditional use and stop there. If you want to know what research is currently exploring, look at independent sources rather than a shop's product page.
