Shilajit is a sticky, tar-like substance found primarily in the rocks of the Himalayas and other high mountain ranges, formed over centuries from the gradual decomposition of plant matter. Rich in fulvic acid and a complex array of minerals, it has been used in traditional Ayurvedic medicine for thousands of years as a rejuvenating tonic. Research suggests that purified shilajit may support healthy testosterone levels and fertility in men, with some studies indicating improvements in sperm quality and energy-related markers. Preliminary evidence also points to potential benefits for cognitive function, nutrient absorption, and exercise recovery, likely linked to its fulvic acid content and antioxidant properties. Studies on its role in altitude sickness and anti-aging are still emerging, and most researchers emphasize the importance of using properly purified forms to avoid contaminants.
