Safety and efficacy of shilajit (mumie, moomiyo)

Shilajit (mumie; moomiyo, mummiyo) has been used for a wide variety of illnesses and conditions for many years. However, relatively few well-controlled human studies have been conducted on the effects of shiliajit, although a growing number of studies have been published in recent years involving animal and in vitro systems. The safety of shilajit is well documented based on animal and human studies. Various research studies indicate that shilajit exhibits antioxidant, anti-inflammatory, adaptogenic, immunomodulatory, and anti-dyslipidemic properties. Animal and human studies indicate that shilajit enhances spermatogenesis. Furthermore, animal and human data support its use as a 'revitalizer', enhancing physical performance and relieving fatigue with enhanced production of ATP. Key constituents in shilajit responsible for these effects appear to be dibenzo-α-pyrones and fulvic acid and their derivatives. Various mechanistic studies provide support for the above observed effects. Additional well-controlled human and animal studies involving the use of standardized products are needed.
