Best time to take ashwagandha

best time to take ashwagandha, according to Andrew Huberman, is later in the day or in the evening. This timing allows ashwagandha to help reduce cortisol levels, which is beneficial since you want cortisol to decrease in the evening to improve relaxation and sleep quality. 1 Additionally, Dr. Huberman mentions taking it before sleep or with your last meal of the day, ensuring it's at least two hours before bed. 1
