HelloPharmacist Scorecard of Shilajit Extract 400 mg by Swanson

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: shilajit extract, 400 mg per capsule. Shilajit is a mineral-rich substance that comes from high-altitude rock deposits.

The capsule itself also contains inactive ingredients — hypromellose, maltodextrin, microcrystalline cellulose, magnesium stearate, and silica — which are fillers and binders that help form and preserve the capsule.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Shilajit's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Total wellness for mind body and home.
  • We looked for evidence on: Athletic performance, Male infertility, Sexual dysfunction, Sexual desire, Fatigue, Cognitive function — and 1 related terms.
  • The closest evidence on file: Shilajit is rated "Insufficient Reliable Evidence To Rate" for Sexual dysfunction (Natural Medicines).
  • Also on file: Shilajit is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Sexual desire, Male infertility.

The evidence for shilajit isn't established in our data. We hold insufficient reliable evidence to rate it for Alzheimer disease, sexual dysfunction, athletic performance, benign prostatic hyperplasia (enlarged prostate), or osteopenia (low bone density).

If you're considering shilajit for any of these reasons, talk with your pharmacist or doctor about what the current science actually supports.

The evidence, ingredient by ingredient Shilajit

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Shilajit is generally well tolerated, though side effects are rare. One case of severe allergic reaction — including hives and anaphylaxis requiring emergency treatment — was reported in a woman who increased her dose from 400 mg to 800 mg; headache has also been reported rarely in clinical research.

The safety data advises against shilajit during pregnancy and breastfeeding because there isn't enough information to know whether it's safe at those times. One important caution: unpurified shilajit products may contain heavy metals or other contaminants.

Use only purified, tested brands like this one.

Side effects, ingredient by ingredient Shilajit

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Shilajit.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check any antidiabetes drug you're taking — medications like metformin, insulin, sulfonylureas, or other blood-sugar-lowering pills. Shilajit may enhance how well they work, which raises your risk of low blood sugar.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Shilajit may be worth trying if you're interested in its traditional uses, but the evidence is still limited. If you take any medication for blood sugar, check it with us first — shilajit can strengthen that effect.

Avoid it during pregnancy and breastfeeding, and always buy purified products from brands you trust.

Antidiabetes Drugs

Taking shilajit with antidiabetes drugs might increase the risk of hypoglycemia.
Most human and animal research shows that shilajit can decrease fasting plasma glucose levels. In an animal model, shilajit 100 mg per kg daily enhanced the glucose-lowering ability of both glibenclamide and metformin when given in combination over a 4 week period. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Shilajit Extract 400 mg by Swanson: Common Questions

Does Shilajit Extract 400 mg by Swanson interact with any medications?
Yes. Based on its ingredients, Shilajit Extract 400 mg has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Shilajit Extract 400 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take shilajit if I'm pregnant or breastfeeding?
No. The safety data advises against it during pregnancy, and safety is unknown while breastfeeding. Talk with your doctor or pharmacist if you're considering it at either time.
What side effects should I watch for?
Serious side effects are rare, but a severe allergic reaction (hives and anaphylaxis) has been reported when someone increased their dose. Headache is also possible but uncommon. If you develop hives, difficulty breathing, or any signs of an allergic reaction, seek emergency care right away.
Does shilajit really work for energy or performance?
The evidence isn't strong enough yet to say. We hold insufficient reliable evidence to rate it for athletic performance or the other conditions it's marketed for.
Why does it matter that I buy a purified brand?
Unpurified shilajit can contain heavy metals and other contaminants that could harm you. This product is purified and tested, so stick with trusted brands like Swanson.
I take metformin for diabetes. Can I use this?
Not without checking first. Shilajit can make metformin work better, which might lower your blood sugar too much. Talk to your doctor or pharmacist — they may need to adjust your dose or monitor your blood sugar more closely.
