The short answer
No studies found. We searched for research on shilajit taken with blood pressure medicines such as amlodipine, telmisartan or losartan and found none. Whether shilajit raises, lowers or does nothing to their effect is not known.
There is a separate question about the product itself. A 2025 lab analysis found thallium, a toxic metal, in raw shilajit from five countries and in supplements bought in Poland, Russia and Kyrgyzstan. No Indian brand was tested, and content varied from sample to sample. If you take a BP medicine, tell your prescribing doctor before you start shilajit, and show them the exact product.
Blood pressure medicines sold in India include Telma (telmisartan), Amlong (amlodipine) and Cardace (ramipril).
At a glance
| What was seen | How it may work | Direction | Evidence |
|---|---|---|---|
| Thallium in raw shilajit and in shilajit supplements[1] | Contamination from the source rock and soil, not an interaction | Exposure to a toxic metal; no effect on BP medicines shown | In vitro |
No listing is not a clearance. A missing interaction here never means a combination is safe.
The evidence, study by study
Lab analysis of shilajit products, Iran, Slovakia and Poland, 2025 In vitro
Chemists tested 13 samples of raw shilajit from Iran, India, Nepal, Russia and Kyrgyzstan, and supplements bought in Poland, Russia and Kyrgyzstan. They found thallium in most samples, up to 0.226 micrograms per gram in raw shilajit and 0.5 micrograms per gram in supplements, or up to 0.095 micrograms in one tablet. No people were studied, and no Indian brand was among the supplements. The authors say thallium builds up in the body and call for regular testing of shilajit products.[1]
What your doctor may watch for
- Your blood pressure at your usual checks, and any new dizziness after you start shilajit.
What to tell your prescribing doctor
You can read this out, or show them this page:
“I am taking, or planning to take, shilajit (name of product, batch, dose) along with my blood pressure medicine. I could not find any study of the two together. Is there any reason I should not, and should my blood pressure be checked?”

Questions people ask
Does it matter which shilajit I buy?
It may. Thallium levels in the 2025 analysis varied a lot between samples and countries, and some supplements held more than the raw resin. The authors also cite earlier reports of arsenic, lead and mercury in shilajit. Keep the pack and its batch number to show your doctor.[1]
Is a gap of a few hours between them enough?
No study has looked at timing for this pair, so there is no evidence for any gap. Ask your prescribing doctor.[1]

Shilajit and diuretics (water tablets)
Not studied in people. In a lab experiment, fulvic acid from shilajit bonded with furosemide. What that means for someone taking both is unknown.
InteractionShilajit and metformin
Not studied in people. We found no human study of shilajit with metformin, and the one rat study could not be checked. Shilajit quality also varies.
InteractionAshwagandha and blood pressure medicines
We found no study of ashwagandha with a named BP medicine. A US health agency lists BP drugs among those it might interact with.
