The evidence in words
What it is
Shilajit is an exudate from mountain rocks rich in fulvic acid and trace minerals, used in Ayurveda for vitality.
How it works
Fulvic acid may act as an antioxidant and mitochondrial support; proposed effects on testosterone and CoQ10 utilization are early.
What the evidence shows
Small trials suggest purified shilajit can modestly raise total testosterone in men and reduce fatigue, with antioxidant effects. Trials are few and small, and unpurified shilajit can carry heavy-metal contamination — purification and sourcing are critical.
Safety & interactions
Purified products are generally tolerated; raw/unpurified shilajit risks heavy-metal (lead, arsenic) contamination. Buy tested product only.
Bottom line
Intriguing early evidence for testosterone and fatigue, but small trials and real contamination risk. If you try it, insist on a purified, third-party-tested source.
