Works like a charm
Size: 81 Count (Pack of 1)
My gastroenterologist told me to take Benefiber, specifically, every day. I looked at a bunch of different kinds within the brand, and settled on this one because it seemed to have fewer ingredients I didn’t want. I was pleasantly surprised to find out they actually taste like candy my kids liked when they were younger.
Yes, they are gummy and stick together a bit, just like any other gummy product, but I had no problems getting them out of their container nor eating them, unlike some reviewers. I keep them in a cupboard in a spot where it’s always an average temp.
You can chew these or just let them dissolve in your mouth, something I do most often. I take them one by one after a meal, letting them slowly melt as I do other things before brushing my teeth.
The best thing? They actually work. You should definitely start small and slowly increase to what is prescribed to you. It makes the process easier and more pleasant. My digestion seems to be better, and I no longer have constipation, just normal, average, healthy stool. They are an expense at the amount my doctor has me on, but they’re worth every penny to not have the awful pain and nausea I had before I started taking them. Highly recommend.

Good stuff, tastes nice, does the job
Size: 81 Count (Pack of 1)
Same as in the retail stores, only it's actually available through Amazon. When we head to the stores to pick it up locally, there's a 90% chance it's out.

Tastes great and works well!
Size: 81 Count (Pack of 1)
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.
