Great for getting a good night's sleep
After a stressful day (aren't they all) I often have trouble getting to sleep. I keep these on my nightstand and take one before bed. I find it allows me to fall asleep easily and stay asleep all night. There is no problem with being groggy in the morning like other sleep aids. Ashwaganda is an adaptogen and is supposed to be helpful for other things too. Been using these for months!

Yummy
I’ve tried many brands of ashwaganda gummies and this one by far tastes the best. No side effects. Good quality and value.
