Shilajit Side Effects: Who Should Avoid Salajeet, and the Bigger Risk Nobody Mentions
Written by Taj Sultan. We sell shilajit, so we have a reason to say it is safe. We'd rather tell you exactly when it isn't. This is general information, not medical advice.
Quick answer
Properly purified shilajit, taken in small amounts, has been well tolerated in the few human studies done so far. The side effects people report are usually mild: an upset stomach, a headache or feeling warm. The bigger risk is contamination: raw or poorly processed resin can contain lead, arsenic, cadmium or mercury, and you cannot see, smell or taste them. Avoid shilajit if you are pregnant or breastfeeding, and speak to a doctor first if you have gout, kidney or liver disease, iron overload, or take medicine for blood pressure, blood sugar or the heart. Whatever brand you choose, ask for a heavy-metal lab report with a report number. Ours is PCSIR report FBRC/SK/ANAL.REP./1006.
What the research actually says about safety
There are only a handful of controlled human trials of shilajit. They used purified, standardised extracts, usually 250 to 500 mg a day for 8 to 12 weeks, in healthy adults, and did not report serious side effects. A 2014 review in Phytotherapy Research (Stohs) reached the same conclusion: purified shilajit appears safe in the short term, and longer, larger studies are still needed.
Two limits matter. First, those studies tested purified material, not raw resin from an unknown source. Second, nobody has studied long-term use over years, or use in people with serious illness. So "safe in a trial" does not automatically mean "safe for everyone, forever".
Side effects people report
| What you notice | What to do |
|---|---|
| Upset stomach, nausea or loose motions | Take it with food or in warm milk, and halve the amount. Stop if it continues. |
| Headache, feeling hot or flushed | Drink more water and reduce the amount. Stop if it doesn't settle in a few days. |
| Dizziness or feeling faint | Stop, especially if you take blood-pressure medicine, and speak to your doctor. |
| Rash, itching or hives | Stop and get medical advice. Don't restart to "test" it. |
| Swelling of the face, lips or throat, or difficulty breathing | This is an emergency. Get medical help immediately. |
None of these is common in the studies, but they are the reactions worth knowing about. Never increase the amount to push through a reaction.
Who should avoid shilajit, or ask a doctor first
| Situation | Our advice |
|---|---|
| Pregnancy or breastfeeding | Avoid. There is no safety data. |
| Children and teenagers | Avoid unless a doctor advises it. |
| Gout or high uric acid | Ask your doctor first. Shilajit is traditionally avoided in gout, and there is no good evidence either way. |
| Kidney or liver disease | Ask your specialist first. |
| Iron overload (haemochromatosis) or thalassaemia with high iron | Ask your doctor first. Shilajit contains iron and other minerals. |
| Diabetes, blood pressure or heart medicine | Ask your doctor or pharmacist to check for interactions. See our guide to shilajit with low BP or diabetes. |
| Upcoming surgery | Tell your surgeon about every supplement you take. |
The bigger risk: contaminated, untested resin
Shilajit forms in rock, so unpurified material can carry the metals that are in that rock. The US CDC has repeatedly warned that some traditional remedies sold in South Asia have contained dangerous amounts of lead. Lead and arsenic build up in the body over time, so a contaminated product you take daily for months is more of a worry than any side effect above.
Home tests don't help here. Shilajit that dissolves in water, stretches when warm or burns without smoke can still contain lead. Only a lab test can tell you. Our guide to checking a shilajit lab report shows what a real one looks like.
That is why we publish our reports in full. PCSIR Laboratories Complex, Lahore, a government laboratory, tested our shilajit for arsenic, lead, cadmium and mercury and detected none of them. BECS Analytics (PNAC-accredited, ISO/IEC 17025) measured 75.17% fulvic acid. Both reports, with their numbers, are on our lab reports page so you can check them with the labs yourself.
How to take it more safely
- Start small. A rice-grain amount for the first week, then up to a pea-sized amount (roughly 300 to 500 mg) once a day.
- Dissolve it in warm water or milk rather than swallowing a lump.
- Take breaks. Many people take it for 8 to 12 weeks, then pause.
- Keep your doctor informed if you take any regular medicine.
- Buy resin with a report number you can verify, from a seller you can contact.
More detail is in our shilajit dosage guide.
Frequently asked questions
What are the side effects of shilajit?
In studies of purified shilajit, side effects were uncommon. People sometimes report an upset stomach, headache, feeling warm or dizziness. A rash or swelling means stop and get medical advice.
Is it safe to take shilajit every day?
Healthy adults in studies took 250 to 500 mg a day for up to 90 days without serious problems. Long-term daily use hasn't been studied, so many people take it in cycles of 8 to 12 weeks with a break.
Can shilajit damage the kidneys or liver?
There is no good evidence that purified shilajit does. Contaminated resin containing heavy metals can harm both, which is why a heavy-metal report matters. If you already have kidney or liver disease, ask your specialist first.
Does shilajit raise uric acid?
It isn't proven either way, but traditional practice avoids shilajit in gout. If you have gout or high uric acid, speak to your doctor before taking it.
How do I know my shilajit is free of heavy metals?
Only a lab test can tell you. Ask for a report that names the lab, gives a report number and lists results for lead, arsenic, cadmium and mercury. Ours is PCSIR report FBRC/SK/ANAL.REP./1006.
