Why Are Prebiotics Important for a Healthy Gut Microbiome?

Probiotics may get all the spotlight, but prebiotics are the unsung heroes of gut health.

By nourishing these friendly microbes, Sunfiber® helps support digestion, improve regularity, and nourish the gut lining from within.* Think of it as prepping the soil before planting seeds - a healthy gut needs strong roots.

What Exactly Is Sunfiber® and Why Is It Good for Gut Health?

What is Sunfiber?

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.*

What’s the difference between soluble and insoluble fiber?

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.*

What are prebiotics?

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.

Is Sunfiber a prebiotic?

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.

What are short chainfatty acids?

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.

What is the difference between guar gum and Sunfiber (guar fiber)?

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.

Is Sunfiber Safe?

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.

Is Sunfiber a Natural Product?

Sunfiber natural guar fiber has been classified as a 100 percent natural ingredient by the International Organization for Standardization (technical specification ISO 19657:2017). 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.

What is the caloric value of Sunfiber?

Each serving of Sunfiber contains just 15 calories.

How should Sunfiber be stored?

Sunfiber should be kept in a cool and dry place. Keep away from excess light, heat and moisture.

What are FODMAPs?

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.

Taking Sunfiber®

Are there side effects of having too much fiber?

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.

What is the recommended dosage for fiber?

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.

How much Sunfiber should I consume?

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.

When should I take Sunfiber?

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.

Can Sunfiber be taken by pregnant or lactating women?

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.

Can children take Sunfiber?

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.

Can Sunfiber be added to hot foods and liquids?

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.

Why is it not recommended to mix with carbonated beverages?

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.
