Shilajit
A mineral-rich resin from the Himalayas — used for energy, stamina, and testosterone for thousands of years. Here's what the science actually says, how to spot fakes, and how to take it properly.
Shilajit is a mineral pitch containing fulvic acid and 80+ minerals that helps your mitochondria produce energy more efficiently. It can improve testosterone, reduce fatigue, and enhance physical performance. The main challenge is finding genuine, purified product.
Good for you if: You feel chronically fatigued, want natural testosterone support, are interested in mitochondrial health, or want an Ayurvedic energy supplement.
Dive deeper into the researchCommon side effects
- Raw/unprocessed shilajit may contain heavy metals — only use purified versions
- Can increase iron levels — avoid if you have hemochromatosis
- May lower blood pressure — monitor if on BP medication
What does shilajit do?
Shilajit's main active compound — fulvic acid — acts as an electron shuttle in your mitochondria, helping them produce ATP (cellular energy) more efficiently. Think of it as giving your cells' power plants a tune-up.
It also contains 80+ trace minerals in ionic form that your body absorbs very well. For men, clinical trials show it can increase total testosterone by 20% and free testosterone by 19% over 90 days, likely by supporting the HPG axis and reducing oxidative stress on testicular function.
What can you expect?
- More energy — genuine, sustained energy improvement (not a stimulant buzz)
- Higher testosterone (men) — measurable increase over 8–12 weeks
- Better physical performance — improved stamina and recovery
- Sharper cognition — some users report clearer thinking
- Better mineral status — especially iron, zinc, and trace minerals
How to take it
250–500 mg of purified shilajit daily — dissolved in warm water or milk. Take in the morning on an empty stomach. Pea-sized amount if using resin form.
Always choose lab-tested, purified shilajit. Raw shilajit from the mountains may contain heavy metals, mycotoxins, and other contaminants.
How to spot fakes: Real shilajit dissolves completely in warm water (no residue), softens when warm, hardens when cold, and has a smoky/earthy smell. If it's a powder that doesn't dissolve or smells like dirt, it's likely fake.
Which form to buy?
| Resin | Capsules | Liquid | |
|---|---|---|---|
| Best for | Purity & potency | Convenience | Quick absorption |
| How much | Pea-sized amount/day | 250–500 mg/day | Per label directions |
| Cost | ₹500–2000/20g | ₹300–800/60 caps | ₹400–1000/bottle |
| Authenticity risk | Lower | Higher — many fakes | Moderate |
Resin form is hardest to fake and generally the most potent. Buy from brands that provide third-party lab testing for heavy metals and fulvic acid content. PrimaVie is the most-studied branded extract.

Get early accessFrequently Asked Questions
Does shilajit really increase testosterone?
Yes — in clinical trials, purified shilajit (PrimaVie) at 250 mg twice daily increased total testosterone by 20% and free testosterone by 19% in healthy men over 90 days. The mechanism appears to be reduced oxidative stress on testicular function and HPG axis support.
How can I tell if shilajit is real?
Real shilajit: dissolves completely in warm water, softens between your fingers, hardens when cold, has a distinct smoky/bitumen smell, and stretches like tar when warm. Fake shilajit: doesn't dissolve, looks like plain dirt, or is a dry powder. Always buy from brands that provide lab-tested purity certificates.
Is shilajit safe long-term?
Purified, lab-tested shilajit is safe for long-term daily use at 250–500 mg. The key word is "purified" — raw, unprocessed shilajit may contain heavy metals and other contaminants that make long-term use risky.
Can women take shilajit?
Yes. While most testosterone studies are in men, shilajit's energy and mineral benefits apply to everyone. Women can take 250 mg daily for energy, mineral support, and antioxidant benefits.
How it works in your body
Fulvic acid acts as an electron transporter in the mitochondrial electron transport chain, improving ATP synthesis efficiency. It also chelates minerals into bioavailable forms, enhancing absorption of iron, zinc, and trace elements. The dibenzo-alpha-pyrones (DBPs) in shilajit protect mitochondrial membranes from oxidative damage and enhance CoQ10 function. For testosterone, the mechanism involves reduced oxidative stress on Leydig cells and improved FSH signaling.
What the studies show
- Testosterone: 20% total T and 19% free T increase in 90-day RCT (PrimaVie 250mg 2x/day)
- Energy: Improved exercise performance and reduced fatigue in multiple trials
- Cognition: Preliminary data suggesting improved cognitive function in elderly
- Antioxidant: Strong free radical scavenging activity from fulvic acid
- Sperm quality: Improved sperm count, motility, and morphology in infertile men
Side effects & safety
Purified shilajit is well-tolerated. The main risk is product quality:
- Heavy metal contamination — Raw, unprocessed shilajit can contain lead, arsenic, and mercury. Only use purified, lab-tested products.
- Increased iron — Shilajit enhances iron absorption. Avoid if you have hemochromatosis or iron overload.
- Blood pressure — May lower BP mildly. Monitor if you're on antihypertensives.
- Uric acid — Shilajit is high in purines. Use with caution if you have gout or high uric acid.
- Allergic reaction — Rare but possible. Stop if you develop a rash or itching.
Who should skip it: People with hemochromatosis, active gout, very low blood pressure, or pregnancy. Anyone using raw/unprocessed products.
Which labs to check
If you want to track your response properly, get these tested before you start and again at 8–12 weeks:
- Total testosterone & free testosterone — the primary hormone benefit to track
- Iron panel (ferritin, serum iron) — shilajit increases iron absorption
- Uric acid — monitor if you have a history of gout
