Key Takeaway
Review of shilajit's neuroprotective potential, highlighting fulvic acid's ability to inhibit tau protein aggregation - a key mechanism in Alzheimer's disease.
Summary
This review examined the scientific evidence for shilajit's potential cognitive and neuroprotective effects, with particular focus on Alzheimer's disease mechanisms.
The authors highlighted that fulvic acid, a major component of shilajit, has been shown to inhibit tau protein self-aggregation in vitro. Tau aggregation is a hallmark of Alzheimer's disease pathology.
The review also discussed shilajit's antioxidant properties, anti-inflammatory effects, and traditional use for cognitive enhancement. The authors concluded that while promising, more clinical research is needed.
