Gentle on Your System
Short Chain Fatty Acids (SCFAs) are produced via fermentation of dietary fiber by the gut microbiome. While some soluble fibers ferment rapidly, leading to excessive bloating and flatulence, Guar Fiber ferments at a gentle pace, promoting a healthy gut without the uncomfortable gas and bloating.*

Low FODMAP Certified
High-fiber foods may trigger gas and bloating in individuals with functional gastrointestinal disorders. Sunfiber, however, is sensitive stomach friendly and very well tolerated, promoting a healthy digestive balance without discomfort.*

Why is Sunfiber superior to other fiber supplements?
Guar fiber, Sunfiber’s fiber source, helps to normalize both occasional constipation and occasional diarrhea. It also won’t lead to excess gas and bloating, common side effects of other fiber supplements.*
When should I take Sunfiber?
Sunfiber may be taken at any time of the day but is recommended to take first thing in the morning to get your digestive system on track for a comfortable day ahead.
Can Sunfiber be used in cooking?
Yes. Sunfiber can be added to recipes for baked goods as well as savory foods without affecting their taste, aroma or texture. It is also an excellent smoothie ingredient.
Are there side effects of having too much fiber?
People who are unaccustomed to getting sufficient dietary fiber – from food or fiber supplements – may sometimes experience gas, bloating and/or diarrhea. Those side effects are virtually non-existent with Sunfiber at the recommended dosages.*

Amazing 🤩
Odourless, tasteless and dissolves easily with no clumps. Ot also has no fillers and does not upset my stomach. Works great at keeping things moving. For all my GLP1 users, this is what you should be using. I’ve been using this product for two years now while on a GLP and haven’t had any constipation issues. Works like a charm. I love it and will continue to buy it.

Tomorrow’s Nutrition
Recently purchased Tomorrow’s Nutrition Sunfiber. It is odorless, tasteless and dissolved easily into my water. After 2 weeks, I am feeling a little better, not as much bloating and am more regular. It is a clean fiber without fillers. No sugar is added. My dr recommended Tomorrow’s Nutrition for my autoimmune/gut issues. Its a 1.39 pound container and a scoop is provided. Great value fir the price and effectiveness.

Best fiber supplement
This product is awesome. I was using a prescription fiber but it went out of stock so I did some research and this was recommended. I’m so glad I switched. It dissolves fully and quickly and literally has no taste at all. It helps keeps me regular and I get more for the money. Highly recommend!

Sunfiber – so glad I found you!
Sunfiber is hands-down one of the best fibers I’ve found for IBS. It’s a generous size that should last a while, low FODMAP, and supports the growth of beneficial gut bacteria, promoting a healthy gut flora. I mix it into my morning matcha and it blends seamlessly with a Ninja blender for a super smooth, virtually invisible consistency. It’s odorless, so I can even sneak it into my partner’s tea without him noticing! I also love that it’s Non-GMO Project Verified.I’ve been gradually increasing my daily intake over the past month, and it’s been gentle on my tummy—exactly what I need for IBS. The container offers excellent value and will last a long time. Plus, the bulk option helps reduce packaging waste, which I really appreciate given the current climate crisis. Overall, Sunfiber is high-quality, effective, and easy on digestion—probably the best fiber I’ve used so far.My advice: start low and go slow. Begin with just ½ to 1 teaspoon and gradually increase your intake as you see how your body responds. Sunfiber is not only a gentle fiber, but also a prebiotic, meaning it feeds the beneficial bacteria in your gut. Slowly building up your dosage helps avoid any discomfort while allowing your digestive system to adjust.

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.

SunFiber is not gritty or thick like similar products
Very good product. No grit, no taste and it works with no uncomfortable cramping. I sprinkle it on my cereal or sometimes put it in my coffee.

Really works… no taste and dissolves completely!
I bought this on a whim. I have IBS and fiber is helpful but often gives me gas. I have not had any excess gas and the product has improved my regularity.It truly dissolves quickly in cold or hot beverages and does not add any taste. My husband is using it now and not a single complaint! He has a lot of constipation and this is one of the few thing that has helped him.Buy it! It is so worth it!
