Excellent product!

### ⭐⭐⭐⭐⭐ Helps greatly to curb cravings
*by A***R on June 23, 2025*

I love this stuff and will keep reordering it because I notice a big difference between when I take it and when I don’t as far as whether or not I have hunger cravings that day. I mix it with some casein protein powder in the morning and never get cravings to eat bad or sugary during the day. It dissolves easily and has no taste aside from a slight texture. I wish I would have found this stuff earlier. It’s slightly pricey for what it is and part of me thinks it could be possible to get as much fiber from other sources, but I think that would cost more in the long run and take much more meal prep planning into account
