Shilajit (Mumie)

Tier 3 — weak evidence · Energy · Testosterone · Anti-aging

Small industry-funded trials show modest testosterone and fatigue benefits, but independent research is scarce. Critical warning: 40% of tested commercial products contained dangerous lead and arsenic levels. Only purified shilajit from NSF or USP certified brands is safe. Uncertified products carry a genuine heavy metal poisoning risk. Long-term safety data beyond a few months does not exist.

Dose: 200–500 mg/day purified form only — NSF or USP certification is non-negotiable; avoid all uncertified products
