Frequently Asked Questions

Sunfiber^® is a clinically studied, soluble prebiotic fiber derived from partially hydrolyzed guar gum that helps support digestive balance and gut microbiome activity.

• Derived from guar beans grown in India
• Produced through a partial enzymatic hydrolysis process to improve solubility
• Studied in adults, including those with digestive sensitivity such as IBS-C
• Helps support beneficial gut bacteria and digestive function
• Designed to be gentle and well tolerated for daily use

Sunfiber^® is a modified form of guar fiber that dissolves easily and does not thicken like traditional guar gum, making it more suitable for daily use and formulations.

• Traditional guar gum is highly viscous and used as a thickener
• Sunfiber^® is partially hydrolyzed to reduce thickness and improve usability
• Mixes clearly into liquids without altering texture
• Suitable for beverages, powders, and functional foods
• Associated with improved tolerance across a wide range of users

Partially hydrolyzed guar gum refers to guar fiber that has been broken down using an enzymatic process with water to create smaller, more soluble components. This improves usability while maintaining its fiber properties.

• Hydrolysis reduces molecular size for better solubility
• Improves mixability in liquids and formulations
• Maintains the functional benefits of soluble fiber
• Supports consistent performance across applications
• Enables easier daily use

Partially hydrolyzed guar fiber like Sunfiber^® is widely used because it combines functional benefits with excellent formulation flexibility.

• Dissolves easily without affecting texture
• Neutral taste allows broad application
• Stable across processing conditions, including pH and temperature
• Works in beverages, powders, and foods
• Supports clean-label formulation goals

Yes. Sunfiber^® functions as a prebiotic fiber by supporting the growth and activity of beneficial gut bacteria and aids gut health.*

• Selectively fermented by bacteria in the colon
• Helps support beneficial microbial populations
• Produces short-chain fatty acids (SCFAs)
• Contributes to gut microbiome activity
• Studied in general and sensitive populations

Short-chain fatty acids (SCFAs) are compounds produced when beneficial gut bacteria ferment soluble fiber and play an important role in gut function.

• Includes butyrate, acetate, and propionate
• Provide energy for colon cells
• Support intestinal barrier functions
• Associated with microbiome balance
• Produced during fermentation of fibers like Sunfiber^®

Soluble fiber dissolves in water and is fermented by gut bacteria, while insoluble fiber primarily adds bulk. Both play complementary roles in digestion.

• Soluble fiber supports microbiome activity
• Insoluble fiber helps move material through the digestive tract
• Sunfiber^® is a soluble fiber
• Soluble fibers are often preferred in sensitive populations
• A balanced intake of both is recommended

Sunfiber^® helps support consistent and comfortable bowel patterns by forming a gentle, soluble fiber matrix in the digestive system.*

• Forms a soft, gel-like structure when hydrated
• Helps support stool consistency*
• Suitable for occasional irregularity*
• Studied in adults with digestive concerns
• Designed for gentle, daily use

Some fibers ferment rapidly in the gut, which can lead to gas or bloating. Sunfiber^® ferments more gradually and is generally better tolerated.*

• Rapid fermentation can increase gas production
• Sunfiber^® ferments at a slower, steadier rate
• Low viscosity supports smoother digestion
• Studied in individuals prone to digestive sensitivity
• Gradual intake increases can improve comfort

Yes. Increasing fiber intake too quickly can lead to temporary gas or bloating as the gut adjusts.

• Rapid increases can overwhelm gut bacteria
• Gradual increases help improve tolerance
• Adequate hydration supports comfort
• Sunfiber^® is generally well tolerated
• Individual responses may vary

Fiber tolerance depends on fermentation rate and viscosity, which influence how the fiber behaves in the gut.

• Rapidly fermenting fibers may increase discomfort
• High-viscosity fibers can feel heavy
• Sunfiber^® is low viscosity and ferments more gradually
• Associated with a favorable tolerance profile
• Suitable for a wide range of individuals

FODMAPs are short-chain carbohydrates that are often poorly absorbed and rapidly fermented, which can cause problems in sensitive individuals. Sunfiber^® is considered low FODMAP at recommended intake levels.

• FODMAPs may contribute to gas and bloating
• Sunfiber^® is low FODMAP within recommended intake ranges
• More suitable for sensitive individuals
• Ferments more gradually than many high FODMAP fibers
• Used in digestive-focused formulations

Yes it can. Sunfiber^® has been studied in individuals with digestive sensitivity, including IBS, and is generally well tolerated when introduced gradually.*

• Low FODMAP at recommended intake levels
• Ferments more slowly than some fibers
• Studied in IBS populations
• May support digestive comfort and regularity*
• Start with a low dose and increase gradually

Many people do not meet the recommended daily fiber intake of 25-38 grams per day. Too little fiber may impact digestive balance.

• General guidelines: 25–38 grams per day
• Typical intake is often 10 g lower
• Low intake may be associated with irregularity
• Increasing fiber gradually may help
• Diet, gender and lifestyle influence needs

Yes. Sunfiber^® is well tolerated and has been evaluated in human clinical studies and GRAS.

• Supported by published safety and tolerability data
• Studied in adults, including digestive-sensitive populations
• Suitable for daily use
• Gradual increases may help minimize discomfort

Clinical studies commonly use doses in the range of 5–10 grams per day, depending on individual needs and current fiber intake.

• Start with a lower amount
• Increase gradually for tolerance
• 5–10 grams per day is a common clinical range
• Can be used consistently for long periods
• Follow product-specific guidance

Yes. Sunfiber^® dissolves easily and is widely used because it does not significantly impact taste or texture.

• Works in hot and cold applications
• Suitable for beverages, powders, and foods
• Does not add grit or thickness
• Easy to incorporate
• Used across many formulations

Sunfiber^® and psyllium are both soluble fibers, but they differ in viscosity, texture, and tolerability.

• Psyllium forms a thick gel
• Sunfiber^® dissolves clearly
• Psyllium may feel heavy or thick
• Sunfiber^® is low-viscosity and easier to use
• Better suited for beverages

Sunfiber^® differs from inulin and FOS primarily in fermentation rate and digestive tolerance.

• Inulin and FOS ferment rapidly
• May increase gas or bloating
• Sunfiber^® ferments more gradually
• Better tolerated in sensitive individuals
• Suitable for broader use

Yes. Sunfiber^® is stable under typical food and beverage processing conditions, including heat.

• Maintains functionality during heat processing
• Suitable for baking and hot-fill applications
