Ashwagandha
Several studies have revealed that ashwagandha (Withania somnifera), an Ayurvedic herb used since ancient times, has substantial therapeutic benefits on brain function. 8-week research of 50 adults found that taking 600 mg of ashwagandha root extract daily significantly enhanced memory, attention, and information processing when compared to a placebo. A five-study meta-analysis discovered that ashwagandha supplementation was well tolerated and resulted in enhanced performance on cognitive tests, attention, and response speed.
A 12-week trial of 50 older persons found that ingesting 600 mg of ashwagandha root extract daily improved sleep quality, mental alertness, and overall quality of life when compared to a placebo group. According to research, ashwagandha may have favorable impacts on cellular energy generation and be a useful tool for improving athletic performance.
