Sunfiber® Water Soluble Dietary Fiber (Partially Hydrolyzed Guar Gum)



Sunfiber® (Partially Hydrolyzed Guar Gum) is an all-natural, water-soluble, non-viscous, non-gelling, dietary fiber that is derived from guar gum. Sunfiber® is a Galactomanan (not a starch or sugar based fiber) treated with a natural enzyme process that lowers viscosity 10-fold and makes it readily soluble in water. Sunfiber® is a patented fiber (both production and use).


Sunfiber® is tasteless, colorless and odorless and has no visible effect on your product but significantly boosts its health benefits. Sunfiber® delivers high fiber content, features a very low viscosity, and exhibits excellent stability with respect to pH, heat and freeze/thaw conditions.


Sunfiber® is clinically proven to lower glycemic index, improve mineral absorption, promote intestinal regularity and maintain digestive health. If you want all the benefits of fiber with none of the negatives, your only choice is Sunfiber®.


Whether it’s included in the food, or taken with water when eating, Sunfiber® helps the body combat increased blood glucose levels by controlling the glycemic index of foods.


Many dietary fibers block the absorption of essential minerals such as magnesium and calcium into the body. Sunfiber®, on the other hand, actually promotes the absorption of these and other helpful minerals, ensuring the body receives the maximum benefits from the foods it digests.


All fibers can help alleviate constipation and irregularity. But Sunfiber® does so without the undesirable and problematic side effects of diarrhea. Sunfiber® alleviates constipation without overly degrading stool firmness. The result is regularity with healthy consistency.

Sunfiber® Normalizes Constipation AND Diarrhea, and is the only fiber strongly recommended for IBS claims and also for childood constipation.

Commonly used soluble fibers such as FOS (Fructooligosaccharides) and Inulin have not been proven to reduce diarrhea and on the contrary can exacerbate gastrointestinal symptoms such as excess gas, bloating and cramping, as well as loose stools and diarrhea due to their rapid fermentation
