(2022). Effects of Acute Ashwagandha Ingestion on Cognitive Function. International Journal of Environmental Research and Public Health, 19(19), p.11852.
- Evaluated the effects of Ashwagandha root extract (400 mg over a single day)
- Improved executive function, helped sustain attention, and increased short-term memory in subjects compared to the placebo group.
- Acute ingestion of Ashwagandha was well-tolerated by participants, with no reported negative side effects
Positives - Study showed that a smaller dose of 400mg compared with 1000mg in previous studies still had a significant effect on cognitive function, even when administered as a once off dose
Negatives - Small sample population (13 participants) and a significant portion of the study population were female.
The short-term nature of the study does not provide information about the long-term effects of Ashwagandha ingestion on cognitive function.
