Shilajit is a sticky substance found primarily in rocks of the Himalayas and is believed to have developed over hundreds of years from the slow decomposition of plants. While Shilajit has a long history of use in Ayurvedic medicine, it has only recently become popular in the West as a source of bioactive Fulvic Acid. Double Wood’s Shilajit contains no fillers and is standardized to 20% bioactive Fulvic Acid, which is seen as the main active ingredient. In addition to this, it may contain up to 84 different minerals.
