Keeps me regular and tastes great
Size: 81 Count (Pack of 1)
If you have trouble with staying regular and experiencing bloating, try these. They taste great and aid in digestion so you stay regular.

Works and taste great!
Size: 81 Count (Pack of 1)
I don't understand how some people are saying the taste of these are bad, I think their good. It took me about a week to set on a amount to take every day and decided on 3, with the help from certain fruits and vegetables I go every day now. Only reason I have it 4 stars and not 5 is bc of the gas it gives. After taking the gummies for about 3 hrs it's Alot of gas and man 🤢 bad!! But these gummies work and I'm not constipated anymore 😊

High quality fiber
Size: 81 Count (Pack of 1)
Excellent fiber. I take it twice a day so it does fast but it's the best fiber gummy I've used in terms of results. Some of the flavors aren't my favorite but they're all palatable. I like the gummies because otherwise I forget to take them. It's hard to remember to take them exactly between other meds so having these sit out helps.

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.
