Shilajit resin: what it is and how to take it

Resin is the form of shilajit closest to how it comes out of the rock: a dark, sticky, tar-like paste, usually sold in a small jar. Capsules, tablets and powder contain shilajit that has been dried, and drops are a liquid. The substance is the same in principle; what changes is how you measure a dose and what else may be added.

Almost all human research used purified shilajit in capsules. Only one published trial has tested resin, so most of what follows is practical guidance built on that one study and on how the other trials dosed shilajit. For how much to take, the shilajit dosage guide is the page to read first.

What is shilajit resin?

Shilajit resin is shilajit sold as a soft, sticky paste. Researchers describe shilajit as a “sticky tar-like resinous substance” found on mountain rocks at high altitude (Kohli et al., 2026), and crude samples are sticky enough that one lab freeze-dried them before analysis (Kamgar et al., 2025).

Here is how resin compares with the other forms you’ll see on sale:

The trials that tested capsules used fixed amounts, for example one capsule of 250 or 500 mg a day (Keller et al., 2019) or a 100 mg capsule twice a day after meals (Biswas et al., 2010). If you want the trade-offs in detail, see shilajit resin vs capsules.

How is purified shilajit resin made?

Purified resin is generally made by dissolving shilajit in water, separating out the insoluble rock and debris, and concentrating what’s left back into a paste. The resin in the one resin trial was described as made in a good manufacturing practice (GMP) facility “using solvent-free aqueous extraction”, standardised to at least 60% fulvic acids, and tested for heavy metals, microbes, pesticides, aflatoxins and polycyclic aromatic hydrocarbons (Yadav et al., 2026).

That is a processed product, not raw material scraped off a rock. “Purified” has no fixed meaning on a label, so a brand using the word should be able to tell you how it was purified and show test results. Researchers have developed lab methods to tell raw material, extract and resin apart by their marker compounds, such as fulvic acid, and their minerals (Kohli et al., 2026). The traditional method, and why most research used purified shilajit, are covered in raw vs purified shilajit.

What does shilajit resin look and taste like?

Shilajit resin is dark brown to black and sticky. Its texture tends to change with temperature: firmer when cool, softer and stickier when warm. The taste is strong, and most people describe it as bitter and earthy. We found no study that formally describes its taste or smell, so treat this as everyday experience rather than a measured fact.

Looks and texture can’t tell you whether a resin is genuine or clean. See fake shilajit for why.

How do you take shilajit resin?

Weigh your dose, dissolve it in warm water, and drink it, ideally with a meal. In the only resin trial, 25 healthy men took 250 mg twice a day, each dose dissolved in about 200 ml of warm water and taken with meals, for 28 days (Yadav et al., 2026). That is 500 mg a day, the most studied daily amount across shilajit trials.

1. Weigh it. 250 mg is 0.25 g. Use digital scales that read to 0.01 g, as guessing by size is unreliable.
2. Dissolve it. Stir it into about 200 ml of warm water until it has dissolved. Warm rather than boiling water is a sensible precaution; no study has tested whether temperature matters.
3. Take it with food. The resin trial gave it with meals. If it upsets your stomach, taking it with a meal is a sensible first change, though that is a precaution rather than tested advice.
4. Start low. Our dosage guide suggests 250 mg a day for the first week, then 250 mg twice a day if you want to. The dosage guide gives the full table.

A clean, dry spoon or the tool supplied with the jar makes handling easier and keeps water out of the jar. If you’d rather not drink it in plain water, see shilajit recipes for other ways to take a measured dose.

The trial itself has real limits. There was no placebo group, everyone knew what they were taking, and four of the six authors work for the company that makes the resin. It tells you how resin was taken in a study, not that resin works better than other forms.

How should you store shilajit resin?

Keep the jar tightly closed, somewhere cool and dry, out of direct sunlight and out of reach of children. We found no study on how long resin keeps or what affects its stability, so this is a sensible precaution rather than tested advice. Follow the best-before date and any storage instructions on the label.

How can you tell if shilajit resin is good quality?

The only reliable way is a lab certificate of analysis for your batch, showing heavy metals, microbial tests and ideally fulvic acid content. Home tests, such as burning a piece or watching how it dissolves, can’t detect lead, arsenic, mercury or microbes.

This matters because contamination is a real risk. Shilajit from India and Pakistan contained lead, arsenic and mercury above permissible limits in one analysis (Aldakheel et al., 2022). In another, some commercial supplements contained more thallium than crude shilajit, up to 0.5 micrograms per gram (Kamgar et al., 2025), so processing alone doesn’t guarantee a cleaner product.

In Great Britain, food supplements must not exceed 3.0 mg/kg of lead, 1.0 mg/kg of cadmium and 0.10 mg/kg of mercury, as sold. There is no set limit for arsenic in supplements. A good certificate gives a number for each metal and matches the batch number on your jar. For more, read heavy metals in shilajit and how to read a certificate of analysis.
