What is shilajit resin?

A sticky mineral-rich substance that seeps from mountain rocks and is used in Ayurvedic tradition. Researchers have found minerals and fulvic acid in it, but composition varies by source.

How do you take shilajit resin?

Follow the label's serving and mixing directions using its measuring tool. No dose is established by good research, so follow the label and start low.

How much shilajit resin per day?

There is no evidence-based daily amount. One small pilot study used 500 mg a day for 28 days, which is not a recommendation.

It depends heavily on purity. NCCIH warns some Ayurvedic preparations contain toxic levels of lead, mercury or arsenic, so only buy products with batch lab results and ask your doctor first.

Shilajit resin: what it is, what the evidence shows and how to buy it safely

Quick answerShilajit resin is a sticky, tar-like substance from mountain rock that is used in Ayurvedic tradition and sold as a supplement. Human evidence is thin: most studies are small, short and often funded by sellers. The bigger concern is purity, because NCCIH warns that some Ayurvedic preparations contain lead, mercury or arsenic at toxic levels. If you buy it, choose a product with published lab results for heavy metals, follow the label and ask a doctor first if you are pregnant or have a health condition.

What shilajit resin is

Shilajit is a natural exudate that seeps from rocks in mountain ranges such as the Himalayas. Researchers describe it as a mineral-rich organic material traditionally used as a rejuvenator. A 2025 chemical analysis in ACS Omega of one Himalayan sample found it slightly alkaline and rich in minerals such as potassium, calcium and magnesium, along with fulvic acid and other organic compounds.

That study also stressed that its findings were hypothesis-generating and need direct testing before any therapeutic claims can be made. Composition also varies by source: a 2025 study in BMC Chemistry measured 14 raw samples from five countries and 6 commercial supplements, and found that geographic origin strongly affected the mineral salt content. It called for standardized formulations and strict quality control.

What the human evidence shows

Most marketing for energy, strength or testosterone outruns the research. One recent example is a 2026 open-label pilot study in Cureus: 25 healthy men aged 21 to 55 took 500 mg a day of a branded shilajit resin (250 mg twice daily) for 28 days, and the authors reported improvements in strength, endurance and fatigue scores compared with their own starting point.

Read that kind of result carefully. There was no placebo group, everyone knew they were taking shilajit, the study was short and small, and it tested one brand. Gains measured against a person's own baseline can come from practice, expectation or training. A finding like this is a reason for better trials, not proof that a jar will raise your energy.

Claim	Evidence status
More energy, less fatigue	Small, uncontrolled studies only
Higher testosterone	Not established in good-quality trials
Antioxidant or anti-inflammatory effects	Mostly lab and chemical analyses
Safe purity	Depends on the product; must be tested

The heavy metal problem

This is the most important buying issue. NCCIH, part of NIH, warns that some Ayurvedic preparations may contain lead, mercury or arsenic in amounts that can be toxic, and notes that FDA has warned that metals in some Ayurvedic products make them potentially harmful.

NCCIH cites a 2015 survey of people using Ayurvedic preparations in which 40 percent had elevated blood lead levels and some had elevated mercury. About one in four supplements tested had high lead levels and almost half had high mercury. A CDC report linked elevated blood lead in a 64-year-old woman to Ayurvedic preparations bought online.

Because shilajit is a raw mineral substance, purity testing is not optional. Look for a recent certificate of analysis from an independent lab that lists lead, mercury and arsenic results for the batch you buy. A vague "lab tested" claim on a listing is not the same thing.

How to take shilajit resin

Resin is sold in jars, often with a measuring tool, and labels give their own serving and mixing directions. There is no established safe or effective dose from good-quality research, so follow the product label and start at the low end.

For reference, the pilot study above used 500 mg a day split into two doses for 28 days. That describes one study, not a recommendation.

Measure with the included tool rather than guessing.
Do not combine it with other shilajit products or blends.
Stop if you notice stomach upset, rash or any new symptoms, and tell your doctor.

Who should avoid it

NCCIH advises people who are pregnant or nursing to talk with their health care provider before using Ayurvedic products, because some may contain harmful substances. The same caution applies to children, who are especially vulnerable to lead.

Tell your doctor and pharmacist about any shilajit use, especially if you have a health condition or take prescription medicines. NCCIH also cautions against using Ayurvedic products to replace conventional care or to delay seeing a provider about a medical problem.

FDA does not approve dietary supplements for safety and effectiveness before they are sold, so the seller is responsible for purity. That is why your own label and lab-report check matters.

How to choose shilajit resin

Ask for the batch lab report showing lead, mercury and arsenic, from an independent lab.
Prefer simple products: resin or a purified extract, not a 10-ingredient blend.
Check the stated amount per serving and how to measure it.
Be wary of big promises about testosterone, stamina or curing anything.
Keep it away from children.

What to look for when you buy

Shilajit resin with a batch heavy-metal lab report

Best for: Adults who have checked with their doctor and want the traditional resin form

Purity is the main risk with Ayurvedic mineral products, so a jar with a current independent certificate of analysis for lead, mercury and arsenic addresses the biggest concern.

Watch out: Benefits are unproven. A marketing claim of testing is not the same as a lab report you can read.

Purified shilajit extract capsules

Best for: Adults who want a measured dose instead of scooping resin

Capsules state a fixed amount per capsule, which avoids guessing a pea-sized portion. Look for a standardized extract with a stated amount.

Watch out: Still check heavy-metal testing. Avoid multi-ingredient blends with herbs you have not looked into.
