I've tried a number of different competing products in this space and found these to be the right combination of tastes good and works well. I do recommend! If they stick together in the container the probably got hot somewhere along the way to your house. Try freezing them and tapping the container ona counter. Should help break them apart.

It works!

This really solved a very obvious problem when one is on a Keto diet. It does the job gently-no side effects. This is a great product at a great price. Thank you.
