Shilajit
The resin itself: what it is, where it comes from, how it is purified, and how to tell a real jar from an expensive one.
Shilajit is a dark, tar-like resin that seeps from layers of rock in high mountain ranges, above all the Himalaya and the Hindu Kush, and also the Altai, the Pamir and the Caucasus. It is neither a plant nor a mineral. It is what remains of plant matter after centuries of decomposition inside the rock: mostly humic substances, with fulvic acid as the largest fraction, carrying whatever trace minerals the surrounding geology contributed. In Russian, German, Polish and Czech the same material is called mumijo, mumie or mumio. One substance, several names, and in the European Union a food supplement rather than a medicine.
What is in a jar is measurable, and we prefer measurements to adjectives. Our supplier's laboratory certificate for the resin we sell reports 73.8 per cent fulvic acid and 14.7 per cent humic acid by HPLC, 14.3 per cent moisture and 11.8 per cent ash, the ash being the mineral fraction. So roughly nine parts in ten of the dry material are humic substances and about one part in ten is mineral. That ratio varies from valley to valley, which is why two honest jars can differ and why the mountain range on a label tells you less than the batch number on a report.
Between the rock and the jar sits a purification step, called shodhana in Ayurveda: the raw material is dissolved, the rock, sand and plant debris that do not dissolve are filtered out, and the liquid is reduced back to a resin. That removes the insoluble matter. It does not, on its own, remove dissolved metals, and raw shilajit can carry lead, arsenic, mercury and cadmium above the permissible limits. The finished batch is therefore tested, and the test is the document that separates a supplement from a story. Regulation (EU) 2023/915 sets the maximum levels for food supplements at 3.0 mg/kg for lead, 1.0 mg/kg for cadmium and 0.10 mg/kg for mercury; our certificate reports 0.44, below 0.2 and 0.03 respectively.
The human evidence is real, narrow and thin: roughly eight small trials, several on one branded extract, measuring androgen levels in men aged 45 to 55, strength retention after a fatiguing protocol in young men, bone mineral density in postmenopausal women with osteopenia, and a handful of laboratory markers. Nothing in that list is a health claim, and under Regulation (EC) 1924/2006 no health claim for shilajit is authorised in the EU. We state what each trial measured, in whom, for how long, and we stop there.
The section below is the map. What is shilajit is the definition in full. Shilajit benefits audits every human trial. Is shilajit safe covers the heavy metals question and how to read a certificate. How to take shilajit is the dose, the timing and a first month. Shilajit side effects names who should not take it. How to spot real shilajit and resin against capsules are the two buying questions, and where to buy shilajit in Europe is the last one.

The questions everyone asks
What is shilajit, actually?
A dark resin that seeps out of rock at altitude in the Himalaya, made of plant matter pressed and broken down over a very long time. What comes off the rock is not the product. Shodhana, the purification step, is what separates the resin from everything it was sitting in, and that is the step worth asking a seller about.
Why does fulvic acid matter?
Fulvic acid is a carrier molecule. It binds trace minerals and is studied as a way of getting them across a cell membrane, which is why the interesting question about a mineral is not how much is in the jar but how much of it arrives. That is the mechanism the research is built on. It is a line of study, not a settled fact, and nobody should sell it to you as one.
How much do I take, and when would I notice anything?
A rice-grain portion, dissolved in warm water or under the tongue, once a day. A 30g jar lasts two to three months at that dose. Shilajit is not a stimulant and nothing here works like one, so the honest unit of time is a month rather than an afternoon. If you want the caffeine experience this will disappoint you.
Resin or capsules?
The range includes resin and six distinct capsule formulas in vegan HPMC shells. Ingredient amounts are listed for each product rather than reduced to one formula for the whole range. One caution: the Sea Moss and Bladderwrack blend contains iodine, so if you have Hashimoto’s or any diagnosed thyroid condition, take that one to your doctor rather than to the checkout.
Where does it come from, and how do I know it is clean?
Our products come from the white-label range offered by established UK supplier Pure Shilajit UK. The supplier describes its resin as Himalayan-sourced. Certificate of Analysis 63849 from Alex Stewart Agriculture, Liverpool (ISO 17025 accredited analyses) covers the February 2026 resin batch: arsenic 0.02, cadmium under 0.2, lead 0.44 and mercury 0.03 mg/kg. It covers the resin only; the capsules are not independently tested.
Do you ship outside Europe?
We ship worldwide, with one exception: not to the United States. Orders to the United Kingdom pay GBP 7.00, free for orders of GBP 140 or more. Switzerland and Europe pay CHF 6.90, free from CHF 150; every other country CHF 14.90, free from CHF 200, converted at checkout.
