About
Not a supplement store with a blog attached. The writing came first, and the jars are what pays for it.
The name
Shilajatu is the Sanskrit the word shilajit was worn down from: shila, rock, and jatu, the exudate that seeps out of it. In German the same substance is called Mumijo, and it is the same substance.
The writing
The site exists because writing about shilajit in English is mostly either supplement marketing or health claims nobody can support. There is very little that simply explains the substance: what it is, how it is purified, what the trials actually measured, how large they were, and which of the things said about it are still open questions.
The jars
The jars came second. We do not collect or purify the resin. Shilajatu selects products offered by established UK supplier Pure Shilajit UK through its white-label programme. The supplier describes its resin as Himalayan-sourced. Certificate of Analysis 63849 from Alex Stewart Agriculture, Liverpool, covers its February 2026 resin batch (ISO 17025 accredited analyses: arsenic 0.02, cadmium under 0.2, lead 0.44, mercury 0.03 mg/kg; fulvic acid 73.8%). It covers the resin only. The capsules are not independently tested; third-party capsule testing is being arranged and nothing about it is published until it exists.

Shilajatu is run by one person,
Nico Jaroszewski, from Winterthur in Switzerland.
Nico manages the shop, product information and customer enquiries. Pure Shilajit UK supplies the range under a white-label arrangement, with orders dispatched from the UK or through Switzerland.
Nico is not a clinician. He holds no medical, pharmacy or nutrition qualification, and no page on this site is written as though he did. Every article is researched by opening the sources it cites, mostly trials and reviews indexed on PubMed and opinions from EFSA and the BfR, and each study is named with its size, dose and duration so you can weigh it yourself. No health claim is made: what a study measured is reported, what it did not measure is said too, and a person edits every page before it is published. Where the evidence is thin or the answer is not known, the article says so.
How we work
01
The writing is the product that comes before the product. If the articles are not worth reading, the jar is just another jar.
02
Unpurified shilajit can carry lead, arsenic, mercury and cadmium. Certificate of Analysis 63849, Alex Stewart Agriculture, February 2026 resin batch, ISO 17025 accredited analyses, states the measured values in full. It covers the resin only.
03
No invented results, no borrowed heritage, no reviews that nobody wrote. Where a trial is small, we say it is small. Where we do not know something yet, the page says so.
04
This is a food supplement. It is not a medicine, it does not treat anything, and nothing here will be written as though it does. What a study measured is worth saying; what it did not measure is worth saying too.
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.
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.
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.
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.
