"I like this powder over others for several reasons: it's tasteless and dissolves completely. No clumps! Mostly, it's done more for my gut than anything else has."













Sunfiber is an all natural truly regulating soluble dietary fiber derived from the guar bean that has an optimal gut transit time.* Sunfiber was awarded Grade A Fiber Consensus Recommendation and a Level 1 Evidence Recommendation (Clinical Nutrition Supplements). Sunfiber acts as the perfect food source for probiotics as well as increasing the helpful bacteria and decreasing the harmful bacteria already within our system.*
Insoluble fiber creates the bulk in your stool. Good sources of insoluble fiber are grains, nuts, seeds and the skins of fruits. Soluble fiber dissolves in water. The right soluble fiber aids digestion, feeds beneficial bacteria, moderates glucose absorption, lowers cholesterol and helps you feel less hungry (increases satiety). But be careful. Some soluble fibers may lead to additional gas, bloating and worse: loose stools and diarrhea. Sunfiber is a soluble, low-FODMAP fiber. It supports digestive health without causing excess gas orbloating.*
These are food for the probiotics. You need these for your probiotics to thrive. However, it is important to choose the right prebiotic fiber that doesn’t result in excess gas, bloating and loose stools.
Sunfiber is a Prebiotic fiber that is unique in comparison to other non galactomannan based fibers. A prebiotic fiber is one that produces “short chain fatty acids” (SCFA) in the gut via a fermentation process. The rate of production of SCFAs is very important. If fermentation occurs rapidly (as is the case with Inulin and other soluble fibers) the result is an excess of uncomfortable bloating and flatulence. The fermentation process of Sunfiber is extremely slow resulting in a higher total amount of SCFAs that are produced over a greater period of time, leading to significantly less gas, bloating and discomfort.
Short Chain Fatty Acids (SCFAs) are small compounds produced via fermentation of dietary fiber by the gut microbiome. The three main SCFAs are acetate, propionate, and butyrate. Butyrate acts as an energy/food source for the cells of the colon and is beneficial for intestinal health.
Guar gum is a water-soluble carbohydrate derived from the guar plant seed. It is used throughout the food industry for its superior thickening, gelling, emulsifying, and stabilizing properties as a result of its high viscosity. While guar gum and Sunfiber (guar fiber) come from the same plant, Sunfiber has a low viscosity and is used to add fiber to various foods and dietary supplements.
Sunfiber has been affirmed as GRAS (Generally Regarded As Safe) by an expert panel at a level up to 60 grams per day and is approved as a fiber source by the U.S. Food and Drug Administration, Health Canada and other countries.

Sunfiber starts with natural guar beans which are grown in fields that are not treated with chemicals. No preservatives or additives are used or added during manufacturing. Sunfiber is certified Kosher, Halal, vegetarian (not of any animal origin nor derivative) and non-GMO Project Verified, Glyphosate Residue Free and 100% Gluten free.

FODMAPs (FermentableOligo-saccharides, Disaccharides, Mono-saccharides and Polyols) are a group of dietary sugars which are poorly absorbed in the small intestine. They are known to cause gas related pain, intestinal distention and constipation and/or diarrhea in people suffering from functional gastrointestinal disorders (FGIDs)and irritable bowel syndrome (IBS). Low FODMAP diets help to reduce these symptoms. Because many high-fiber foods are also high in FODMAPs, people with FGID and IBS typically have difficulty meeting the recommended daily intake of25 to 30 grams of fiber in their diets. That means they may not get enoughsoluble fiber which is essential for gut health and regularity. Sunfiber isproud to be the first prebiotic fiber to achieve Low FODMAP certification. Sunfiber is a Monash University Low FODMAP Certified™ product.
People whose bodies 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.
The current adequate intake for dietary fiber is 25 grams/day for women and 38 grams/day for men.Most of us get just 10 to 15 grams per day.
The typical recommended single serving of Sunfiber 7 grams. The current adequate intake for dietary fiber is 25 grams/day for women and 38 grams/day for men. The daily amount of Sunfiber that should be consumed by healthy people looking to meet the daily recommended level of fiber would be the difference between their fiber intake from food and that of the recommendedfiber intake for men and women.
Sunfiber may be taken at any time of the day but is often recommended to take first thing in the morning to get your digestive system on track for a comfortable and healthy day. Take with your morning cereal, yogurt, smoothie or add to your water bottle to take with you on the go.
Sunfiber has been consumed by pregnant and lactating women for years, and it has been shown to be a safe way to improve regularity and reduce cramping and bloating.* As with any supplement, however, please consult with your health care practitioner prior to use if you are pregnant or breastfeeding.
Sunfiber is appropriate for all ages to address digestive irregularity and to maintain regularity.* The recommended dosage of 1 serving (7 grams) is the same for all ages above 9 months.
Sunfiber is tasteless and mixes easily into many foods and beverages. Sunfiber may be added to any recipe when cooking and baking. Simply stir in Sunfiber until dissolved.
The recommendation not to mix Sunfiber with carbonated beverages is simply that the carbonation can make it difficult to dissolve the product. Other than that, there isnothing wrong with consuming Sunfiber with carbonated water or other carbonated beverages.
