Best Fiber Supplement
[This review was collected as part of a promotion.] I think I have tried just about every fiber supplement on the market. SunFiber was recommended to me by friends. They said their doctor recommended it to them. I had never heard of it and was skeptical, but I was anxious to to find a good fiber supplement. Well, I believe I have found it!!! difference.

Great fiber!
[This review was collected as part of a promotion.] The fiber dissolves perfectly with really no taste or flavor. It works well and I find it is more effective than straight up psyllium husk by far.

Easy dissolve
[This review was collected as part of a promotion.] Our 4 year old daughter had SIBO and her GI doctor recommended we add this to her daily routine. So far it’s been great and she doesn’t notice it at all! I’m starting to take it myself too!

Actually helps me stay regular without feeling bloated
[This review was collected as part of a promotion.] I’ve tried a lot of fiber supplements and this one has honestly been one of the easiest to stick with. It mixes well, tastes good, and doesn’t leave me feeling heavy or uncomfortable afterward. I noticed a difference in digestion and regularity pretty quickly, and I also like that it fits easily into my morning routine. Definitely feels gentler than some other fiber products I’ve tried. Would repurchase.

Works great
[This review was collected as part of a promotion.] Sunfiber works great for me. I put a scoop in my smoothie everyday for a little boost of fiber. I hear it can help reduce cholesterol too.

celiac relief
[This review was collected as part of a promotion.] I have celiac and needed a good prebiotic to keep a healthy gut and minimize any discomfort. This has been excellent and I love waking up without gas and some abdominal discomfort. I'm a science based person and truly believe in this product

So easy to take
[This review was collected as part of a promotion.] I was previously using a fiber supplement from a well known MD, yet it had a flavor I didn't like and caused some histamine reactions. This is flavorless and so easy to use. Plus it feels great.

Great natural alternative to Metamucil.
[This review was collected as part of a promotion.] Took a few days to kick in and start working, which I guess is to be expected. Works great though! Takes a lot of stirring to get it fully mixed.

Surprisingly Good!
[This review was collected as part of a promotion.] Finally a fiber supplement that I can take daily without dread!! When mixed with water, It turns into a completely colorless, tasteless, liquid that can be easily consumed daily to add significant fiber into my diet.
