Shilajit raw stone comes from the Himalayan mountains. Higher Shilajit are considered more potent and of better quality. Our Shilajit comes from the Gilgit Mountains at an altitude of approximately 17,500 (+) feet. Although all Shilajit quality is pure, the filtration process plays an important role. Ancient Therapy Premium Shilajit is filtered 5 times leaving no residue.
