Is Shilajit Safe? Side Effects, Drug Interactions, and Who Should Avoid It

Shodhit (purified) Shilajit has an excellent safety profile when sourced correctly and taken at recommended doses. Classical Ayurvedic texts document its use across thousands of years without significant adverse event reports. Modern clinical studies have confirmed safety at doses up to 500mg per day in healthy adults.

The critical safety factor is purification. Raw, unpurified Shilajit contains heavy metals (lead, mercury, arsenic) present in the Himalayan rock it seeps from. Classical Shodhan (Triphala-based purification) removes these impurities while preserving the therapeutic compounds. Always verify that your Shilajit has been purified and has a third-party NABL lab certificate confirming heavy metal levels below safe thresholds.

Side effects: At therapeutic doses (300–500mg daily), side effects are rare. The most commonly reported are mild digestive warmth in the first week (normal as the body adjusts) and very occasionally mild headache (typically a detoxification response, resolves within 3–5 days). These resolve without discontinuation in most users.

Drug interactions: Shilajit may interact with blood thinners (warfarin, aspirin therapy), immunosuppressants, and antidiabetic medications (Shilajit can enhance insulin sensitivity — monitor blood glucose if on medication). Consult your physician before starting Shilajit if you are on prescription medication.

Who should avoid Shilajit: Pregnant and breastfeeding women (insufficient safety data for this population). People with haemochromatosis (iron overload). People with acute active infections or high fever. Children under 12. Anyone with a known allergy to Himalayan minerals.
