Sunfiber GI combines clinically proven Sunfiber with a scientifically backed probiotic. This all-natural blend delivers true regularity, addressing both occasional constipation and diarrhea, without excess gas, cramping or bloating.*

Soluble Fiber

Clinically proven Sunfiber supports a comfortably balanced gut by moving food through your system at just the right pace. It’s specially formulated to be gentle on your insides. As a prebiotic fiber, it also nourishes the good bacteria in your gut.


Billions of active probiotics work in harmony with the fiber to promote a healthy microbiome and support gut health.* Bifidobacterium lactis is a powerful strain revered for its ability to survive the harsh conditions of the gut.

Each serving of Sunfiber GI contains 5 grams of prebiotic fiber and 8 billion active probiotics.

In addition to promoting a healthy digestive balance, Sunfiber GI supports weight management goals by helping you feel fuller longer.* Sunfiber GI also reduces the glycemic index of foods, which helps decrease the post-meal glucose spike.*

Just like Sunfiber, Sunfiber GI is easy to use. It dissolves quickly and clearly in beverages and foods without changing the taste, odor or texture.

Sunfiber GI is Non-GMO Project Verified, 100% gluten-free, vegetarian, Kosher, Halal, Monash University Low FODMAP Certified™ and Glyphosate Residue Free Certified.
