Shilajit

Also sold as Mumijo, mineral pitch, purified shilajit resin

A mineral-rich resin used for energy, testosterone, and exercise recovery — evidence is early and product quality varies enormously.

Evidence strength

40/100Limited
WEAKLIMITEDMODERATESTRONGVERY STRONG

What the evidence supports: modest gains in strength, endurance, and testosterone markers in small, often industry-funded trials.

This scores how well-supported the claim above is — not how much benefit you personally would get. A high score on a narrow claim does not extend to everything the product is marketed for.

How long to take it

Course-based, typically 8–12 weeks in the trials that exist. Not established for indefinite daily use.

Who it's actually for

People exploring natural support for testosterone, energy, or exercise recovery — but only from a product with an independent Certificate of Analysis for heavy metals.

Safe upper limit

Unverified
No formal upper limit — the real safety concern is heavy-metal contamination, not dose
Shilajit forms geologically and readily absorbs lead, arsenic, cadmium, and mercury from surrounding rock. Independent testing (ConsumerLab, 2024) has found meaningful contamination in some commercial products. Fulvic acid — shilajit's main bioactive — is an efficient carrier molecule, which means it can enhance absorption of contaminating heavy metals just as effectively as it enhances absorption of the beneficial minerals.

Practical notes

  • Never take unpurified, raw, or traditionally-processed shilajit — only lab-purified resin or extract.
  • Look for third-party heavy-metal testing (ICP-MS) and a Certificate of Analysis from the brand, not just a purity claim on the label.
  • Fulvic acid content is rarely standardized between brands — 'shilajit' on a label doesn't guarantee a comparable dose to what was studied.
  • Caution with reduced kidney function — heavy metal clearance is slower, so contamination risk compounds.
