The basics
What is shilajit?
A dark, sticky organic-mineral material that seeps from rock in mountain ranges such as the Himalayas. It is made largely of humic substances plus plant and microbial metabolites.[1] Full guide
Where does shilajit come from?
Mainly high mountain ranges in South and Central Asia, especially the Himalayas and Hindu Kush.[1] An origin on a label is a claim until documents support it. Origin and geography
What is shilajit made of?
Fulvic acids, dibenzo-alpha-pyrones, proteins and minerals are reported as its main components,[2] in proportions that vary between samples. Composition
What does shilajit taste like?
Bitter, earthy and smoky. Resin is usually dissolved in a warm drink; capsules avoid the taste. Look, smell and taste
Benefits and evidence
Does shilajit work?
For a few topics there are one or two small human trials with positive results, mostly using one branded extract. No benefit is established. Our ratings put every topic at “Limited” or below. Evidence by topic
Does shilajit increase testosterone?
One randomised trial in 75 healthy men aged 45–55 reported higher testosterone than placebo after 90 days.[3] It hasn’t been independently repeated. Testosterone evidence
Is shilajit good for women?
Two small randomised trials in women exist: one on bone density after menopause[4] and one on sexual function.[5] Pregnancy hasn’t been studied. Women’s health evidence
Does shilajit help with energy?
Everyday energy and fatigue haven’t been tested in controlled human trials. The nearest evidence is one exercise study measuring strength after a fatigue test.[2] Energy evidence
How long does shilajit take to work?
Trials measured outcomes after 8 to 48 weeks.[2][4] There is no evidence for quick effects, and no evidence that taking more speeds things up. How to use shilajit
Safety
Is shilajit safe?
Small studies of processed shilajit haven’t shown toxicity,[6] but they can’t detect rare or long-term effects. Contamination with metals is the main practical risk. Safety guide
Does shilajit contain heavy metals?
It can, because it forms in contact with rock. Thallium has been measured in commercial supplements.[7] Ask for a batch COA with a metals panel. Contaminants
Can I take shilajit while pregnant or breastfeeding?
There is no safety data. Avoid it unless a clinician advises otherwise. Pregnancy and breastfeeding
Does shilajit interact with medicines?
No formal interaction studies have been published that we are aware of. That is a gap, not reassurance; check with a pharmacist. Medication interactions
Can athletes take shilajit?
Shilajit isn’t banned, but any supplement can be contaminated. UK Anti-Doping advises batch-tested products because strict liability applies.[8] Sport and anti-doping
Buying and quality
How can I tell if shilajit is real?
Home tests can only rule out crude fakes. A batch-specific COA covering identity, metals and microbiology is the only practical check. Real vs fake
What should a shilajit lab report include?
A named laboratory, a batch number matching your jar, a test date, and numerical results with units and detection limits for metals, microbiology and identity. Laboratory testing
Does a successful test purchase prove shilajit is genuine?
No. A purchase shows that ordering and delivery worked for that order. Authenticity needs identity and contaminant evidence linked to the batch you received. See how we evaluate brands.
Is resin better than capsules?
Neither is better in principle. Resin has fewer ingredients; capsules give a precise dose. Compare shilajit content per serving and the batch COA. Shilajit forms
Is Himalayan shilajit the best?
No published evidence shows one origin is better. Contaminant levels vary within a range, so testing matters more. Himalayan vs Altai
How much should shilajit cost?
Compare cost per gram and per serving rather than jar price. Calculator · UK prices
Which shilajit brand is best?
We only rank brands after they’ve been through the same published evaluation. UK brands · How to choose
Using shilajit
How do you take shilajit resin?
Measure a serving, dissolve it in warm water, tea or milk, and drink it. A scale reading to 0.01 g gives the most consistent dose. How to use shilajit
How much shilajit should I take?
There is no official dose. Trials used about 200–500 mg a day of specific extracts.[3][9][4] Follow your product’s label. Studied vs label doses
When is the best time to take shilajit?
No study has compared times of day. Consistency matters more than timing. Timing and duration
How should I store shilajit?
Sealed, cool and dry. Resin softens in warmth and hardens in cold; neither is a defect. Storage and shelf life
UK rules
Is shilajit legal in the UK?
It is openly sold as a food supplement, and food law applies: safety, labelling, contaminant limits and claims rules. Is shilajit legal in the UK?
