Great product
This fiber dissolves very well and is tasteless and textureless and easy on the stomach! The large size is a good value as well because I use it every day.

Love this giant container of my favorite fiber! This product was recommended to me by my dietician - after doing a bit of research, it was easy to see why! This 90-day serving size is economical and makes it so easy to incorporate into my daily routine. SO grateful for Sunfiber! I know I'm getting a high-quality supplement that is great for my gut health. :)

SunFiber is an exceptional digestive aid tool
I have been taking SunFiber for over a year. It is an exceptional digestive aid for my system, aiding in regularity and elimination. I appreciate how it dissolves quickly and completely, even in plain water. I have found all claims on the website to be true for me. I highly recommend SunFiber!
