About

A publication that sells the resin it writes about

Not a supplement store with a blog attached. The writing came first, and the jars are what pays for it.

The name

Resin of the rock.

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

Why the site exists

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

Where the jars come from

The jars came second. We do not collect the resin and we do not purify it: it is made for us by a specialist supplier who does, at GMP-certified facilities, from material collected in the Himalaya. That is the ordinary arrangement in this category and most shops would rather you did not know it. What we can control is which batch goes in the jar and whether the certificate for it is on the page.

What we believe

The lab report
is the product.

Who runs it

Shilajatu is run by one person,
Nico Jaroszewski, from Winterthur in Switzerland.

There is no team page here because there is no team, and inventing one would be the first thing on this site that was not true. The writing, the design records, the photographs and the replies to the inbox are all the same person. That is slower than a company, and it is the reason nothing here has to be approved by anyone before it can be honest.

How we work

Four rules we do not bend

  1. 01

    Content first

    The writing is the product that comes before the product. If the articles are not worth reading, the jar is just another jar.

  2. 02

    The report or nothing

    Unpurified shilajit can carry lead, arsenic, mercury and cadmium. Every batch is third-party tested and the certificate is published. A jar that cannot show you one is asking for faith.

  3. 03

    Say what is true

    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.

  4. 04

    Describe, do not promise

    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.

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?

Resin is the whole-spectrum mineral load and it tastes like it does. Capsules are 500mg split evenly between a standardised active and purified resin, in a vegan HPMC shell with no rice flour, no magnesium stearate and no bulking agent. Six blends, each built on the same resin. One caution: the Sea Moss and Bladderwrack blend is naturally high in 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?

Collected at altitude in Nepal and purified in a GMP-certified facility. Rock carries whatever the rock carried, which in the Himalaya can mean lead, arsenic and mercury, so every batch is tested for heavy metals by a third-party laboratory and a certificate of analysis is held for the batch you receive. A jar that cannot show you what came out the other side is asking you to take that on faith.

Do you ship outside Europe?

The launch markets are the EU, the UK and Switzerland. Australia, New Zealand, Canada and Ireland get shipping rates without a localised site. Rates and delivery times go up once fulfilment confirms them.
