Showing its effect immediately
Flavor Name: Unflavored, Size: 300 Count (Pack of 1)
I had been struggling with digestive issues for a long time. Regularity came back within just a few days. The capsule form is very convenient, no need to drink powder. 300 capsules last a long time. Highly recommend.
