Shilajit is generally considered safe when properly purified and used within recommended doses. However, potential contamination with heavy metals and mycotoxins, especially in unprocessed or counterfeit products, remains a concern.

Is Shilajit Safe?

In its natural form, Shilajit is likely to have a number of impurities — such as heavy metals and microbial organisms (viruses, bacteria, fungi) — that aren’t appropriate for human consumption. A 2024 review of recent research found that raw shilajit often contains toxic materials including aluminum, arsenic, cadmium, chromium, mercury, thallium, lead, and fungus.

Processed Shilajit Safety Profile

Processed Shilajit, when administered within the range of 100-2,000 mg/day, does not cause significant toxicity in terms of liver, kidney, or blood function.

Potential Side Effects

While generally well-tolerated, some users may experience:

• Gastrointestinal issues: Nausea, vomiting, diarrhea (usually from excessive dosage)
• Headaches and dizziness: Rare, often temporary
• Skin redness: Observed in one 14-week clinical trial in middle-aged women
• Hormonal effects: Increased testosterone and follicle-stimulating hormone levels have been observed
• Allergic reactions: Very rare; one case of anaphylaxis reported

How to Choose a Safe Shilajit Product

A 2025 study found that some Shilajit supplements actually had higher levels of the toxic heavy metal thallium than the raw variety — proving that not all “purified” products are equal.
