Historically, shilajit has been used to improve memory and cognition, which has led to the promotion of shilajit for conditions like Alzheimer’s disease. Currently, there is no strong evidence to support this recommendation.
In vitro research has provided possible mechanisms for such an effect, including enhanced cholinergic signaling (important for memory and learning)[1] and the ability of fulvic acid — one of the principal active compounds in shilajit — to disassemble and prevent the formation of tau protein aggregates[2] (clusters of proteins thought to contribute to neurodegenerative diseases like Alzheimer’s). Despite this, the available evidence in human clinical trials to date has been unconvincing.[3][4]
