Shilajit: What the Clinical Evidence Actually Shows, and How to Buy It Safely in India
Share
Short answer: Shilajit has one genuinely good human trial behind its most-repeated claim — a randomised, double-blind, placebo-controlled study of 96 men aged 45–55 taking 250 mg of purified shilajit twice daily for 90 days, which found significant increases in total and free testosterone versus placebo (Pandit et al., Andrologia, 2016). That is real evidence, but it is largely one study, in middle-aged men, and it does not tell you what happens in a healthy 25-year-old. The far more important issue when buying is purification: raw shilajit scraped from rock crevices can carry heavy metals, mycotoxins and free radicals, so unpurified or untested product is a genuine safety risk, not just a quality one. Check for a stated fulvic acid percentage, a documented purification process and third-party heavy-metal testing before you buy from anyone. This article is general information, not medical advice.
What is shilajit?
Shilajit is a sticky, tar-like exudate that seeps from rock layers in mountain ranges including the Himalayas, formed over centuries from compressed plant matter. Its principal characterised component is fulvic acid, alongside dibenzo-alpha-pyrones, humic substances and trace minerals. It has a long history in Ayurvedic practice, which is where most of its reputation comes from — tradition is not the same as clinical evidence, and it is worth keeping the two separate when you evaluate claims.
It is sold in three main forms: resin (the sticky purified extract, closest to the traditional material), powder, and capsules or tablets. Resin is generally regarded as the least processed of the three, though what matters more than format is whether the material was properly purified and tested.
Does shilajit actually increase testosterone?
There is one good randomised controlled trial supporting it, and you should know its exact parameters rather than the marketing version. Pandit and colleagues (Andrologia, 2016) randomised 96 healthy men aged 45 to 55 to 250 mg of purified shilajit twice daily or placebo for 90 days. The shilajit group showed significant increases in total and free testosterone compared with placebo, along with increases in DHEA-S.
What that trial does not establish:
- That the same effect occurs in younger men with normal testosterone. The study population was 45–55.
- That the hormonal change translates into strength, muscle mass or body-composition gains — those outcomes were not the endpoint.
- That effects persist beyond 90 days, or that they hold at lower doses or with unpurified material.
Independent assessments generally rate the overall evidence base as limited, precisely because so much rests on this single primary trial. Supporting research has looked at mitochondrial function and fatigue markers, which is mechanistically interesting but not the same as replicated clinical outcomes.
The honest position: shilajit is one of the better-supported traditional supplements in this category, and it is still a long way from established. If a seller quotes you a precise percentage testosterone increase without naming the study, its population and its dose, treat that as marketing.
Why does purification matter so much?
This is the part that actually affects your safety, and it gets far less attention than the testosterone claims. Raw shilajit is collected from rock crevices in unregulated environments. In unprocessed form it can carry heavy metals, mycotoxins and free radicals. Purification removes these — which makes it a safety step, not a premium feature.
India has a genuine problem here: shilajit is widely sold in unregulated forms, including roadside and marketplace product with no processing documentation whatsoever. Heavy-metal contamination in poorly sourced traditional preparations is a documented concern, not a hypothetical one.
The four things to check before buying any shilajit
- A stated fulvic acid percentage. Concentrated purified extracts typically fall in the 50–70% range. A product that states no percentage gives you no basis for comparison against anything else.
- A documented purification process. The seller should be able to say how the raw material was processed.
- Third-party heavy-metal testing, with a certificate available. Not “lab tested” as a claim on the label — an actual report.
- A stated dose. Research doses sit around 250–500 mg daily. A product that will not tell you how much you are taking is not a product you can evaluate.
Apply these to every seller, including us. A brand that cannot answer all four has not earned your money.
How do you take shilajit?
Typical research and label doses are 250–500 mg daily. Resin is usually taken as a rice-grain to pea-sized portion dissolved in warm water or milk; capsules are taken with water. Consistency matters more than timing — the trials that show effects ran for 90 days, so anything promising a difference within days is not describing how this works.
| Form | Typical use | Notes |
|---|---|---|
| Resin | Rice-grain to pea-sized portion in warm water or milk | Closest to traditional material; dosing is by eye unless the pack specifies |
| Capsules / tablets | Per label, usually 250–500 mg daily | Easiest to dose accurately and to travel with |
| Powder | Per label, mixed into liquid | Check what the powder is standardised to |
Who should not take shilajit?
- Anyone under 18.
- Women who are pregnant or breastfeeding.
- People with haemochromatosis or iron overload — shilajit can contain iron.
- Anyone with a hormone-sensitive condition, or taking medication for a hormonal, cardiac or psychiatric condition, without speaking to their doctor first.
- Anyone with gout or elevated uric acid, as a precaution.
- Athletes in tested sport should confirm current WADA and federation guidance for any supplement and prefer third-party-tested products.
If you have symptoms that make you think your testosterone is low — persistent fatigue, low libido, mood changes — get a blood test and see a doctor. Low testosterone is a diagnosable, treatable medical condition, and a supplement is not the right first move.
Frequently asked questions
Does shilajit increase testosterone?
One randomised, double-blind, placebo-controlled trial of 96 men aged 45–55 taking 250 mg of purified shilajit twice daily for 90 days found significant increases in total and free testosterone versus placebo. It is genuine evidence but largely a single study, in a middle-aged population, and results in younger men with normal levels may differ.
How long does shilajit take to work?
The trial that showed hormonal changes ran for 90 days. Expect to judge it over months, not days. Any product promising results within a week is not describing how the studied effects developed.
Is shilajit safe?
Purified, third-party-tested shilajit at 250–500 mg daily is generally well tolerated in the available research. The real risk is unpurified shilajit, which can carry heavy metals, mycotoxins and free radicals. Purification is a safety step, not a marketing claim.
What fulvic acid percentage should shilajit have?
Concentrated purified extracts typically state 50–70% fulvic acid. The important thing is that a percentage is stated at all — without one you cannot compare two products meaningfully.
Is resin better than capsules?
Resin is the least processed form and is closest to the traditional material, but capsules are easier to dose accurately and to travel with. Purification and testing matter far more than which format you choose.
Can you take shilajit every day?
Daily use at 250–500 mg is the pattern used in research. Some people prefer to cycle it, though there is no strong evidence requiring that. If you are taking it long-term, it is sensible to mention it to your doctor at your next check-up.
How can you tell if shilajit is fake?
You largely cannot, by eye. Colour, smell and the widely repeated “dissolves in warm water” test do not verify purity or rule out heavy metals. The only reliable check is documentation: stated fulvic acid content, a described purification process, and a third-party heavy-metal test certificate.
Where can I buy purified shilajit in India?
Muscleape sells Himalayan shilajit resin and Shilajit Gold, with free shipping across India and a 30-day no-questions-asked return policy that covers opened tubs. Apply the four checks above to us and to anyone else you are considering.
