Benefiber is beneficial
Flavor Name: Unflavored, Size: 1.1 Pound (Pack of 1)
Benefiber works well with my IBS-C along with other supplements. It’s so much better than that other “orange-Flavored”product. This dissolves easily and is tasteless.

Great Product
Flavor Name: Unflavored, Size: 1.1 Pound (Pack of 1)
Just mix well - clumping only problem in iced drinks for me
Love that it is tasteless , as product .
I dust over hot meals and all disappears into hot food before I get to table.
I’ve reordered multiple times.

Good quality
Flavor Name: Unflavored, Size: 1.1 Pound (Pack of 1)
Seems to work as expected and looks consistent in quality. The only problem I have with it, is the opening being too small for my hand when it is running low. I bought a another brand last time with the same quality and I could reach inside. I comfortably fit men's large size gloves, so my hands aren't huge. Maybe a long handle scoop would help...

No taste or texture - it completely dissolves!
Flavor Name: Unflavored, Size: 1.1 Pound (Pack of 1)
Easy way to add fiber to diet. Stir it in coffee or a non-carbonated cold drink. You can't tell it as even added because it completely dissolves.
