Shilajit is a sticky, mineral-rich exudate from mountain rocks, containing fulvic acid and trace minerals, marketed for energy, testosterone and vitality.
A few small human studies report increases in testosterone or reduced fatigue with purified shilajit, but the evidence is early and limited. Crucially, unpurified shilajit can be contaminated with heavy metals, so purity and sourcing are a genuine safety concern.
