Evidence strength

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.

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.
