Shilajit – What It Is, Fulvic Acid and How to Use It
Shilajit is a naturally occurring, tar-like substance that forms over a very long time in mountain regions such as the Himalayas, and which has traditionally been used in Ayurveda. What makes shilajit talked about is its content of fulvic acid and minerals. Shilajit has no EU-approved health claims, so below we describe what the substance is, how to recognise quality and how it is traditionally used – not promised health effects.
If you want to compare shilajit with another popular substance, we have a separate article: shilajit vs Tongkat Ali.
What is shilajit?
Shilajit is a resin- or tar-like material that seeps out of cracks in rock, above all in highlands such as the Himalayas, the Altai and the Caucasus. It is thought to have formed over a very long time through the slow breakdown of plant material, which gives it a complex composition of humic acids (above all fulvic acid and humic acid) and trace minerals. The name comes from Sanskrit and is usually translated roughly as "conqueror of mountains".
In the Ayurvedic tradition, shilajit has a long history of use as a strengthening substance. On the market it is most often sold as a purified resin (paste) or in capsule form as a standardised extract.
Shilajit and mumijo – are they the same thing?
You often come across the word mumijo (also spelled mumie or mumiyo) in the same context. Mumijo is in practice the same type of mountain resin and the name is used above all in Russia, Central Asia and the Altai, while "shilajit" is the Ayurvedic, South Asian term. The composition can vary with origin, but it is the same kind of substance.
What is fulvic acid – and why is it always mentioned?
Fulvic acid is a group of organic acids formed when plant material breaks down, and it is shilajit's most talked-about component. Together with humic acid it makes up the so-called humic acids. Extracts are often standardised on their fulvic acid content specifically, since it is a measure of concentration and purity. A quality extract clearly states its fulvic acid content.
The fact that fulvic acid is the marker shilajit is measured on does not mean that a specific health effect is proven or approved – it is a quality and concentration measure, not a health claim.
Resin or capsule – what is the difference?
Shilajit is sold in two main forms. Which one suits you is mostly a matter of practical preference, not that one would have any proven effect over the other.
| Form | How it works | What to keep in mind |
|---|---|---|
| Resin (paste) | A sticky, purified resin dissolved in a warm drink. Dosed in very small amounts. | Gives you control over the amount but is messy to handle; the dose per serving is less exact. |
| Capsule/extract | Standardised powder in a capsule with a stated fulvic acid content and amount per capsule. | Simple, odourless and precisely dosed. Practical if you want to avoid the taste and know exactly how much you are getting. |
Whatever the form, it is crucial that the material is purified and tested – see the section on purity below.
How to recognise quality
| Look for | Why |
|---|---|
| Stated fulvic acid content | Shows concentration and that the product is standardised |
| Purified extract | Untreated raw material can contain contaminants and heavy metals |
| Laboratory tested | Third-party testing for purity is a reassurance marker |
| Clear origin | Reputable manufacturers state where the raw material comes from |
Purity in particular is important with shilajit, since untreated material from nature can contain heavy metals. Therefore choose a purified, tested extract. See Super Strong Shilajit or Shilajit Extract 400 mg from Swanson, or our whole shilajit category.
Purity and heavy metals – the most important thing to understand
This is the single most important issue when it comes to shilajit. Since the substance forms in bedrock and is collected from nature, raw, untreated material can contain heavy metals such as lead, arsenic, cadmium and mercury, as well as other contaminants. It is therefore not a product you should buy unregulated or "straight from the source" without documentation.
Here is how to minimise the risk:
- Choose a purified extract – the purification and filtration process is there to remove contaminants from the raw material.
- Demand third-party testing. A reputable manufacturer has an independent laboratory analyse each batch for heavy metals and can show a certificate of analysis (COA).
- Check that the analysis covers lead, arsenic, cadmium and mercury. Those are the metals most relevant to mountain resin specifically.
- Look at origin and manufacturer. A clearly stated origin and an established manufacturer with traceability are reassurance markers.
In short: do not buy unidentified raw material, and rather choose a product that openly reports purity and testing.
How to test authenticity at home
Besides relying on the manufacturer's documentation, there are a few simple tests traditionally used to judge whether a resin is genuine. They are indications, not laboratory analysis – they can reveal crude fakes but say nothing about heavy metal content. A lab certificate is still the only thing that gives a reliable answer on purity.
| Test | How to do it | What genuine resin usually shows |
|---|---|---|
| Solubility in water | Dissolve a small piece in warm water. | Dissolves and colours the water golden-brown to red-black, without sandy sediment or an oily film. |
| Consistency with heat | Hold a piece between your fingers for a while, then put it somewhere cold. | Becomes soft and pliable with heat and hardens in the cold. |
| Solubility in alcohol | Put a piece in pure alcohol. | Essentially does not dissolve, unlike many additives. |
| Smell | Smell the material. | Has an earthy, mineral smell – not chemical or plastic-like. |
For capsules and standardised extracts, these home tests are not relevant – there you rely instead on the stated fulvic acid content and third-party testing.
How is shilajit used?
- Capsule/extract: follow the dosage on the packaging – around 300–500 mg per day is common.
- Resin: a small amount (often the size of a grain of rice) dissolved in warm water or milk.
- Timing: flexible; many take it in the morning with a drink.
- Storage: store resin at room temperature and dry – that makes it easier to dose – and always follow the packaging's instructions.
Who should be careful?
Pregnant and breastfeeding women are advised against it. Always choose a purified, laboratory-tested extract to minimise the risk of heavy metals, and consult a doctor if you have an illness or take medicines. Raw, untreated shilajit should be avoided.
Frequently asked questions (FAQ)
Shilajit has no EU-approved health claims, so we cannot promise any effect. It is a naturally occurring substance rich in fulvic acid and minerals, with a long tradition in Ayurveda.
What is fulvic acid in shilajit?Fulvic acid is a group of organic acids formed when plant material breaks down, and it is shilajit's most talked-about component. Extracts are often standardised on fulvic acid content as a measure of concentration and purity.
How do I know shilajit is genuine?Look for a purified extract with a stated fulvic acid content, third-party testing for purity and a clear origin. Raw, untreated material should be avoided since it can contain heavy metals.
How much shilajit should you take?For capsules/extract, around 300–500 mg per day is common – always follow the packaging's dosage. Resin is dosed in very small amounts, often dissolved in a warm drink.
Who should avoid shilajit?Pregnant and breastfeeding women are advised against it. If you have an illness or take medicines, consult a doctor. Always choose a purified and laboratory-tested extract.
Are shilajit and mumijo the same thing?In practice, yes. Mumijo is the name used in Russia, Central Asia and the Altai, while shilajit is the Ayurvedic, South Asian name for the same kind of mountain resin. The composition can vary with origin.
Resin or capsule – which should I choose?It is a practical question. Capsules/extract are odourless and precisely dosed, while resin is dissolved in a warm drink and gives you more control over the amount but is messier. Neither form has any EU-approved effect over the other – choose what suits you, and in both cases prioritise a purified, tested material.
Does shilajit contain heavy metals?Raw, untreated material can contain heavy metals such as lead, arsenic, cadmium and mercury since it is collected from bedrock in nature. That is why you should choose a purified extract that is third-party tested and where a certificate of analysis (COA) can be shown.
How do I test whether shilajit resin is genuine at home?Traditional indications are that genuine resin dissolves in warm water and colours it brown/red-black, becomes soft with heat and hardens in the cold, does not dissolve in alcohol and has an earthy smell. These tests can reveal crude fakes but say nothing about purity – only a lab certificate settles that.
How do you store shilajit?Store resin at room temperature and dry, which also makes it easier to dose. Always follow the storage instruction on the packaging.
Summary
Shilajit is a traditional, fulvic-acid-rich substance where quality and purity are absolutely decisive – choose a purified, tested extract with a stated fulvic acid content. Explore our shilajit category or compare in the article shilajit vs Tongkat Ali.
