Shilajit Side Effects: Is It Safe and Who Should Avoid It?

Shilajit is a traditional Himalayan mineral resin that many people take daily for energy and vitality.* But is it safe, what side effects can it cause, and who should avoid it? This honest guide covers what's known, the real risks of poor-quality shilajit, and how to take it safely.

Is shilajit safe?

For most healthy adults, purified, tested shilajit taken at the labeled serving is generally well tolerated. Human studies using purified shilajit (for example around 250 mg twice daily for up to 90 days) did not report serious side effects.

The biggest safety issue isn't shilajit itself; it's quality. Raw or unprocessed shilajit can contain contaminants, which is why purification and independent testing matter so much.

Possible side effects

Side effects are uncommon with quality shilajit, but some people report:

  • Digestive discomfort: an upset stomach or nausea, especially when taken on an empty stomach
  • Feeling warm or flushed
  • Headache or dizziness in some people
  • Allergic reactions, such as rash or itching (stop use and seek advice if this happens)

Starting with the labeled serving, taking it with food or a drink, and staying consistent helps most people avoid discomfort.

The real risk: contaminated, low-quality shilajit

Raw shilajit comes from mountain rock and can contain:

  • Heavy metals such as lead, arsenic and mercury
  • Microbes and fungi, including mycotoxins
  • Free radicals and other impurities if not processed properly

Cheap, untested resins sold online are the main source of these concerns. That's why you should only buy shilajit that is purified and third-party tested every batch for heavy metals and contaminants.

Who should avoid shilajit or check with a doctor first?

Talk to your healthcare professional before using shilajit if you:

  • Are pregnant, trying to conceive or breastfeeding: there isn't enough safety research, so it's best avoided
  • Have hemochromatosis or high iron levels, as shilajit naturally contains iron
  • Have gout or high uric acid: traditional guidance advises caution
  • Take blood pressure or blood sugar medication: shilajit may affect these, so your doctor should know
  • Have a heart condition, a hormone-sensitive condition, or any chronic illness
  • Are under 18: shilajit supplements are intended for adults

Can you take too much shilajit?

More is not better. Stick to the serving on your label, and don't combine several shilajit products (for example capsules and gummies) on the same day unless your healthcare professional advises it. Taking more increases the chance of stomach upset without proven extra benefit.

How to take shilajit safely

  1. Buy purified, tested shilajit from a brand that tests every batch for heavy metals and contaminants.
  2. Follow the labeled serving.
  3. Take it earlier in the day, with food or mixed into a warm drink.
  4. Stay hydrated.
  5. Stop and seek advice if you notice any unusual reaction.

Frequently asked questions

Does shilajit affect blood pressure?

Some reports suggest it may lower blood pressure. If you have low blood pressure or take blood pressure medication, check with your doctor first.

Can women take shilajit?

Yes, adult women can take shilajit, except during pregnancy, while trying to conceive or while breastfeeding, when it's best avoided.

Is it safe to take shilajit every day?

Shilajit is traditionally taken daily. Studies of purified shilajit lasted up to about 90 days. Follow your label and check in with your healthcare professional for long-term use.

How do I know if my shilajit is contaminated?

You can't tell by looking. Only buy from brands that test every batch with an independent lab and can share results.
