Shilajit safety: risks, limits and precautions
Shilajit cannot be called safe across the board, because long-term data from controlled human studies are missing. The best documented risks sit in the goods themselves: heavy metals, mineral oil, misidentified product and poorly cleaned raw material. A lab analysis of the specific batch makes these points checkable, but it does not replace medical advice during pregnancy, with an illness or alongside medication.

Online, the question of Shilajit safety usually gets one of two answers: "completely harmless" or "dangerous heavy metal resin". Neither survives a closer look. This page sets out what is documented, what nobody knows and what you can check yourself. Most official sources here are German, because Germany's food control authorities have published the most useful product testing so far.
Is Shilajit safe?
There is no blanket answer, for three reasons:
- The research is thin. Controlled human studies are rare, small and short. Many papers come from cell cultures or animal experiments. They do not support statements about years of use.
- Shilajit is not a uniform substance. The state food laboratory CVUA Stuttgart describes it as a poorly defined mass. A study on one extract says little about another product.
- The risk depends on the batch. Two jars with the same name can show very different values.
"Safe" is therefore the wrong category. The better questions are which risks exist, how well they are documented and which of them you can check.
| Risk | Documented by | Can you check it? |
|---|---|---|
| Heavy metals | Official findings, EU maximum levels | Yes, through individual batch values |
| Mineral oil (MOSH/MOAH) | CVUA Stuttgart 2026 | Only if the seller has it measured |
| Wrong identity, adulterants | CVUA Stuttgart 2026 | To a limited degree, see below |
| Microbiology of raw material | Cleaning as a production step | Yes, through the batch datasheet |
| Interactions with medicines | German consumer advice centre note, hardly any studies | No, ask a doctor |
| Tolerance of the resin | Few studies, individual case reports | Only individually |
Is Shilajit dangerous?
The documented problems mainly concern the goods and less often the cleaned resin. The most important official source in Germany is the CVUA Stuttgart investigation of 29 April 2026, covering twelve products:
| Test point | Finding |
|---|---|
| Heavy metals | No excessive levels in any of the 12 samples |
| MOSH (mineral oil) | Elevated in 4 of 12 samples, up to 290 mg/kg |
| MOAH (aromatic mineral oil) | Clearly elevated in 1 sample, not marketable |
| Identity | Reasoned suspicion in 3 samples of only traces of Shilajit or none at all |
Twelve samples are a spot check, not a picture of the whole market. The German consumer advice centre Verbraucherzentrale refers to earlier findings of elevated heavy metal levels in Mumijo. Taken together, the sober conclusion is that the risk is real but depends on the product. Our article What do doctors say about Shilajit? covers the views of authorities and experts in detail.
How high is the heavy metal load in Shilajit?
There is no universal figure, because origin and cleaning determine the values. Any analysis can be compared with the maximum levels for food supplements in Regulation (EU) 2023/915. Converted to a 400 mg serving (0.0004 kg), they show the upper end of what a still compliant product could contain:
| Element | EU maximum level | Calculated per 400 mg |
|---|---|---|
| Lead | 3.0 mg/kg | 1.2 micrograms |
| Cadmium | 1.0 mg/kg | 0.4 micrograms |
| Mercury | 0.10 mg/kg | 0.04 micrograms |
| Arsenic | no general maximum level | only calculable from a measured value |
The calculation only works with real measurements and applies to this one serving. Double the amount and you double the intake. Our article on Shilajit and heavy metals explains how to read a test report.
For reference, these are the measured values of our batch HM-SH-25-BLY-1159, tested by a food laboratory in Germany, accredited for heavy metals and microbiology:
| Element | Measured value |
|---|---|
| Lead (Pb) | < 2 mg/kg |
| Cadmium (Cd) | < 0.5 mg/kg |
| Mercury (Hg) | < 0.01 mg/kg |
| Arsenic (As) | 0.88 mg/kg |
Values with a less-than sign are below the limit of quantification. MOSH, MOAH and an identity test are not reported on our datasheet. That is exactly the gap the CVUA points to. All data are on the lab values page and in the batch datasheet.
Is Shilajit free of heavy metals?
No, and no natural resin is. Shilajit forms in direct contact with rock that contains geogenic elements. "Heavy metal free" is therefore an advertising phrase that does not hold up analytically, since every measuring method has a limit of quantification. When you see that wording, ask for the individual values and the limit of quantification.
Does Shilajit detox heavy metals?
You will often see this on social media. The EU register contains no authorised health claim for it, and we know of no solid evidence in humans. That humic substances can bind metals in the lab is chemistry, but it says nothing about what happens in the body.
There is also a logical problem: Shilajit itself brings traces of exactly these elements. If you suspect exposure, have it measured and assessed by a doctor instead of tackling it with a food supplement.
Mineral oil and identity: the underrated points
Online, almost everything revolves around heavy metals, yet the CVUA sample showed its findings elsewhere. According to the European Food Safety Authority (EFSA), MOSH can accumulate in body tissue, including the liver, as our article Shilajit and the liver explains.
A standard lab certificate often does not settle identity. The authority considered the term "lab tested" partly misleading, because the certificates it was shown often covered only microbiology and heavy metals. An analysis describes only the parameters listed on it. What was not measured is neither proven nor ruled out. Our guide on how to spot real Shilajit gives plausibility checks, but they do not replace lab evidence.
Raw material is a separate topic: uncleaned Shilajit contains rock residue and plant matter and is not a ready-to-eat product. A seller should disclose the microbiology results of the finished batch.
Who Shilajit is not suitable for
For these groups, data are missing or the risk of misjudging the situation is higher:
| Group | Reason | What to do |
|---|---|---|
| Pregnant and breastfeeding women | No safety data, one case report (see below) | Do not take without medical advice |
| Children and adolescents | No data | Not suitable |
| People with chronic illnesses | Not studied | Ask a doctor first |
| People on medication | Possible binding of medicines in the gut | Check with a doctor or pharmacy first |
| People with known allergies to natural products | Individual reaction possible | Check first or avoid |
The case report by Stavropoulos et al., 2018 describes a 37-year-old pregnant woman with persistently high blood pressure and low potassium after six months of Mumijo. A single case does not prove a link for everyone, but it is a reason for caution.
The Verbraucherzentrale also notes that humic acids can bind medicines in the gut. How much that matters for which medicine has hardly been studied. So Shilajit belongs on the list of products you mention to your doctor or pharmacist.
What happens if I take Shilajit every day?
Nobody can say reliably for long periods, because the studies are missing. One thing is clear: every serving also brings all the traces it contains, and the amounts add up over time. The case report above concerns six months of use.
Our resin follows a fixed plan: 400 mg a day for 50 days, then 10 days rest. That is an intake rhythm, not proof of harmlessness. Our dosage guide shows how to measure the serving without scales.
Can Shilajit cause skin side effects?
Allergic reactions are possible in individual cases with any natural product, including rash or itching. We know of no frequency data for Shilajit. If a skin reaction appears, stop taking the product and have it checked by a doctor. With breathing difficulty or swelling of the face or throat, call emergency services at once (112 in the EU). Our article on Shilajit side effects covers other complaints and what to do.
What are the downsides of Shilajit?
- Unclear benefit: No health claim is authorised for Shilajit. The assessment of submitted claims is still pending at EU level.
- Thin data: Few and short human studies, no long-term data.
- Confusing market: Suspected fakes, mineral oil findings and advertising that the CVUA objected to in all twelve samples.
- Variable composition: A measured value only ever applies to one batch.
- Everyday use: The taste is bitter and smoky, and resin is sticky and harder to portion than a capsule.
Our article on whether Shilajit is legal explains the legal position around Mumijo.
Checklist: how to check a product
- Is there a batch number on the packaging and a document for exactly that batch?
- Does it list individual values for lead, cadmium, mercury and arsenic, instead of "heavy metal free"?
- Were microbiology and, if stated, mineral oil and identity tested? What is missing?
- Does the seller promise effects? That is not permitted under Regulation (EC) No 1924/2006 and says something about how they treat rules.
- Is the daily serving clearly stated, and do you stick to it?
- Do you belong to one of the groups in the table above? Then ask a doctor first.
Our 20 g jar with batch number and datasheet is available in the shop for €34.00. Whether Shilajit is an option for you depends on your own situation.
Food supplements are not a substitute for a balanced and varied diet.
Frequently asked questions
Is Shilajit safe?
A blanket statement would not be honest. Controlled human studies are small and short, and long-term data are missing. For products, the risk depends heavily on the batch, which is why the lab analysis of the specific goods matters. During pregnancy or breastfeeding, with an illness or alongside medication, the decision belongs with a doctor.
Is Shilajit free of heavy metals?
No. Shilajit forms in contact with rock, so geogenic elements are always present in traces. Free of heavy metals is analytically impossible. What matters is whether the measured levels are below the maximum levels of Regulation (EU) 2023/915 and whether arsenic is reported, which has no general maximum level for food supplements there.
Does Shilajit detox heavy metals?
There is no authorised health claim for that, and we know of no solid evidence in humans. That humic substances can bind metals in the lab says nothing about what happens in the body. Shilajit also brings traces of these elements with it. If you suspect exposure, have a doctor look into it.
Can Shilajit cause skin side effects?
Allergic reactions are possible in individual cases with any natural product, including rash or itching. We know of no frequency data for Shilajit. If a skin reaction appears after taking it, stop and have it checked by a doctor. With breathing difficulty or swelling, call emergency services at once (112 in the EU).
What happens if I take Shilajit every day?
That has not been studied well over long periods. The only certain part is the arithmetic: every serving also delivers all the traces it contains, and the amounts add up. Our plan is 400 mg a day for 50 days, then 10 days rest. That is a rhythm, not proof of safety.
What are the downsides of Shilajit?
Thin research, variable composition, a market with suspected fakes and possible mineral oil residues, the strong taste and the price compared with capsules. Humic acids can also bind medicines in the gut. There is no authorised health claim for Shilajit.
