Evidence Level
Shilajit is a natural mineral substance that has garnered attention for its potential health benefits. Research indicates that purified forms of shilajit may enhance physical performance and improve various physiological markers. A study by Pandit et al. (2016) demonstrated that PrimaVie extract, a purified form of shilajit, significantly increased testosterone levels in healthy aging men. Additionally, Bhattacharyya et al. (2009) found that processed shilajit improved mitochondrial energy status in mice through CoQ10 activation.
Recent studies have further explored shilajit's effects on physical performance and health markers. Yadav et al. (2026) conducted a 28-day open-label pilot study with TruBlk™ Shilajit Resin, finding improvements in muscle strength (+12.94%), endurance (+12.30%), VO₂ max (+1.36%), and reduced fatigue (-32.40%) in healthy males. Martinez et al. (2025) reported that 12 weeks of supplementation with chromium, Phyllanthus emblica fruit extract, and shilajit improved cardiometabolic markers, body composition, strength, and aerobic capacity in sedentary men and women.
Safety considerations are paramount, as raw or unpurified shilajit may contain harmful substances. Only purified, tested products should be used. While the evidence is promising, larger and longer-duration randomized controlled trials (RCTs) are needed to confirm these findings.
