Shilajit and Stiftung Warentest: the honest state of play in 2026
Stiftung Warentest, the German consumer testing body, has published no test of Shilajit to date, and Öko-Test has no test report on it either (as of August 2026). A seller who advertises with a test verdict therefore does not mean these two institutes. The substitute yardstick is what a consumer test would measure anyway: heavy metals, microbiology and fulvic acid, each per batch and determined by an accredited laboratory.
"Shilajit Stiftung Warentest" is one of the most searched terms around the natural resin, and the answer is short: there is no such test. Neither Stiftung Warentest nor Öko-Test, the two best-known German consumer testing bodies, has published a test report of its own on Shilajit or mumijo to date (as of August 2026). Anyone who advertises with a test verdict anyway means something else. This article puts the situation in context and shows which yardstick you can apply instead.
The state of play in 2026: no test, no grade
Stiftung Warentest keeps a publicly searchable database of all published investigations. A search for "Shilajit" or "Mumijo" returns no test report on these products. The same goes for the Öko-Test database.
That is not surprising. Both institutes test when there is a reason and cover a limited number of product groups per year, mostly those with wide market reach or current consumer relevance. In Germany Shilajit is a young niche market with many small sellers, which makes a representative sample difficult.
The reverse matters: the absence of a test says nothing about the quality of individual products. It only means that the most convenient quality signal of all, a grade awarded by a third party, is not available here. You have to look for yourself.
What "tested" in Shilajit advertising actually means
The word "tested" is not legally protected. In shops you find it for very different things:
- Lab tested: a sample was analysed in a laboratory. That is only meaningful with individual values, a batch number and a statement on whether the laboratory is accredited.
- Tested by customers: this means reviews, so opinions, not measurements.
- Self-tested: an internal sensory or handling test without analysis.
- Test winner: without naming the institute, issue and year, this is an empty claim.
A genuine test verdict from Stiftung Warentest may only be shown with a licence and only for the specific product, always with grade, issue and year. If these details are missing next to a logo, something is wrong. How to separate advertising claims from documented facts in general is shown in the guide on spotting real Shilajit.
The substitute yardstick: check what a test would check
A consumer test of a food supplement consists at its core of laboratory analysis plus a check of the labelling. You can ask for exactly these test points on any product yourself, without waiting for an institute.
| Test point of a consumer test | Where you find the information yourself |
|---|---|
| Contaminants (lead, cadmium, mercury, arsenic) | batch datasheet with individual values in mg/kg |
| Microbiology (salmonella, E. coli, yeasts, moulds) | batch datasheet, result per parameter |
| Declared constituents | statement on fulvic acid including the measuring method |
| Traceability | batch number on jar and document |
| Labelling | serving recommendation, mandatory notes, seller address |
| Value for money | price per daily serving instead of price per jar |
The last point is often underestimated. A 50 g jar for 30 euros sounds cheaper than a 20 g jar for 24.99 EUR, but it says nothing about the cost per day as long as the usual daily serving is not fixed. At about 400 mg per day, 20 g lasts 50 days on paper, which is 0.50 EUR per day.
Our numbers as an example of a readable batch datasheet
So that the yardstick does not stay abstract, here are the values determined for the current batch HM-SH-25-BLY-1159 by an accredited food laboratory in Germany:
| Element | Measured value | EU maximum level |
|---|---|---|
| Lead (Pb) | < 2 mg/kg | 3.0 mg/kg |
| Cadmium (Cd) | < 0.5 mg/kg | 1.0 mg/kg |
| Mercury (Hg) | < 0.01 mg/kg | 0.10 mg/kg |
| Arsenic (As) | 0.88 mg/kg | no general maximum level |
The maximum levels come from Regulation (EU) 2023/915 and apply to food supplements sold in the EU. Values with a less-than sign lie below the limit of quantification of the method, so the laboratory could not detect the substance in a measurable amount. What these details mean in full is covered in the article Shilajit and heavy metals.
Fulvic acid needs some context: for our batch 69.8 % was reported, determined by titration. According to the report this parameter was subcontracted and is not covered by the accreditation, unlike heavy metals and microbiology. Why percentages for this parameter say little without a stated method is explained in the article fulvic acid in Shilajit. All figures are in the batch datasheet.
Printable checklist: your own consumer test
Take these eight points into every shop. A seller who meets six of them is set up to be checked; one who stays under four is mostly selling text.
- Is there a document with individual values for lead, cadmium, mercury and arsenic?
- Are these values set against a limit so you can put them in context?
- Does it include a microbiological result (salmonella, E. coli, yeasts, moulds)?
- Does the document carry a batch number that is also on the jar?
- Does it say whether the testing laboratory is accredited, and for what?
- Is the measuring method given for fulvic acid?
- Are seller address, serving recommendation and best-before date complete?
- Can you calculate the price per daily serving because amount and serving size are given?
If you notice a seal that looks like a test verdict, check three details: institute, issue, year. If one is missing, treat it as decoration.
Why we do not wait for a test verdict
A test verdict is a shortcut, not a condition. As long as there is none, only the longer way remains: have every batch tested before sale, publish the values with the batch number and write down the method, even where it contains a limitation.
That is what we do. Should one of the institutes test Shilajit in future, we will update this page with the actual result, however it turns out for us.
More buying criteria are collected in the guide, the resin itself is available as a 20 g jar in the shop, and delivery terms are on the shipping page.

Frequently asked questions
Has Stiftung Warentest tested Shilajit?
No. The Stiftung Warentest test database has no published test on Shilajit or mumijo (as of August 2026). To be sure, search test.de for the keyword yourself: the database can be searched for free, only the full test reports cost money.
Is there an Öko-Test on Shilajit?
Öko-Test has not published a test report on Shilajit or mumijo either (as of August 2026). Both institutes test when there is a reason and do not cover every niche. The absence of a test is therefore not a statement about the quality of individual products, simply a gap.
What does it mean when a shop advertises with 'tested'?
'Tested' is not a protected term and can mean anything from a real laboratory analysis to an internal taste test. What matters is whether concrete measured values, a batch number and an accredited laboratory are named. If one is missing, the statement cannot be checked.
May a seller use the Stiftung Warentest logo?
Only with a paid licence and only for the specific product tested, with the specific verdict, issue and year. A logo without issue, year and product is a warning sign, because those details are mandatory.
How do I recognise good quality without a test verdict?
By checkable numbers rather than adjectives: individual values for lead, cadmium, mercury and arsenic, a microbiological result, a statement on fulvic acid including the measuring method, and a batch number that is also on the jar. That lets you check yourself what a testing institute would otherwise check for you.
Will Shilajit ever be tested?
That cannot be predicted. Both institutes choose topics by market relevance and consumer interest, and the Shilajit market in Germany is young. Until then, the batch analysis is the only reliable proof you can read for yourself.
