Keeps you regular as long as you take them regularly
Flavor Name: Unflavored, Size: 300 Count (Pack of 1)
If you take stuff that keeps you from being regular this is a must have. The pill form is the best as the gummies never work for me. Also works great with Miralax.

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!
