Should I take ashwagandha for sleep?

This question is about Nutrition

Yes, you can take ashwagandha for sleep. Several small studies suggest ashwagandha can improve sleep, particularly in those who have stress-related insomnia [

]. 

A systematic review of five randomized controlled trials observed a small but significant improvement of overall sleep, with the most notable differences observed in those diagnosed with insomnia and who took ≥600 mg/day for eight or more weeks [

1

]. Another recent study of 60 people found that those who took 300 mg of ashwagandha twice daily for ten weeks experienced better sleep quality than those who took a placebo [

2

]. Researchers believe these effects stem from triethylene glycol (a compound known to induce sleep) and withanolides (substances that appear to improve the body’s ability to cope with stress) [
