Efficacy and Safety of Ashwagandha (Withania somnifera (L.) Dunal) Root Extract in Improving Memory and Cognitive Functions.
Researchers conducted a randomized, double-blind, placebo-controlled study to investigate the effects of ashwagandha on cognitive function in adults aged 35-85 years. The study consisted of 50 participants who received either 300 mg of ashwagandha or a placebo twice daily for 8 weeks. Cognitive function was measured using various tests. The study found that the ashwagandha group had significant improvement in tests related to executive function, attention, and information processing speed compared to the placebo group. No adverse effects were reported. These findings suggest that ashwagandha may have potential as a safe and effective supplement for improving cognitive function in older adults. However, larger and longer-term studies are needed to confirm these results.
