Shilajit extract is encapsulated in HPMC capsules that are vegan approved.
Shilajit is a mineral-rich substance found in Himalayan rocks. Its formation occurs over hundreds of years, as plant matter decomposes. Traditional ayurvedic practitioners use shilajit for improved healthspan and slower aging. It may also help treat Chronic Fatigue Syndrome, and preliminary results from one trial indicate that it may help boost testosterone levels. In the trial, half of the participants received a placebo and the other half received a 250mg dose of purified shilajit twice daily for 90 days. At the end of the trial, the group that took shilajit had significantly higher testosterone levels than the placebo group.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3296184/
