Easy addition of fiber - no weird mouth feel!
Excellent product! Dissolves completely in water (I use it in slightly warm water) and does not have any discernible 'feel' in your mouth, which is what I was most worried about. It DOES have a very slight nutty/almond flavor, which isn't off-putting to me. Really would be an easy addition to your morning coffee. And a scoop a day really does help curb cravings and lessens my hunger. Very pleased with the price, the quality, the instructions and packaging, and at a fair price.

Stool softener
Wonder powder. My Gastrointestinal suggests it. Fast working. No taste. Only problem is the price a bit steep

Regulated bowel movements
I suffered from severe bloating and constipation. I switched from my previous fiber supplement to this one and after one month I saw a huge difference. My bloating decreased significantly, my cravings decreased, and I had healthy bowel movements. I love that there's no gross texture or taste. This stuff was a game changer for me. I'm only giving it four stars instead of five because sometimes it makes my stool soft to the point where it's hard to pass, so sometimes I have to skip a day or two. Besides that, I'm so grateful for this supplement it's brought me so much relief.

High Quality Fiber Supplement
Mixes well into my morning coffee - doesn’t ever clump and I don’t taste it. Helps me meet my fiber goals. I use an app to make sure I choose high quality supplements, and this one is great.

Sun Fiber Works Great
This product was recommended for me by my gastroenterologist. It has worked great for me. It mixes well with— even with water. I like using it with cranberry juice. Cranberry is a strong flavor and it dilutes well. It helps eliminate some of my bowel issues.

Excellent fiber powder. Will make the holiday meals easier.
No grit, no flavor. Just a fiber that works. I’m on my fourth bottle and it’s just a reliable product. Scoop goes in my morning coffee. Is helpful after a heavy meal (lookout holidays) or a really sweet dessert.
