Fibalance® is a PARTIALLY HYDROLYZED GUAR GUM (PHGG) prebiotic fiber developed by ZymeBase / ECA Healthcare — derived from guar bean (Cyamopsis tetragonoloba). Distinguished by Low FODMAP CERTIFIED status by Monash University, ~85% soluble dietary fiber content, and gentler GI tolerability than fermentable prebiotics like FOS/inulin. Used for IBS-friendly fiber supplementation, microbiome support, and constipation/regularity in those who can't tolerate other prebiotics.

Studied Dose 5-10 g/day; clinical trials commonly 5-6 g/day
Active Compound Partially hydrolyzed guar gum (PHGG)

Benefits

Low FODMAP Certified — IBS-Friendly Fiber

Distinguishes Fibalance® from FOS, inulin, and other high-FODMAP prebiotics that worsen IBS symptoms. Monash University Low FODMAP Certified. Allows fiber supplementation for IBS patients without symptom flares. Foundational positioning.

Constipation Relief

PHGG generally improves stool frequency and consistency in chronic constipation. Multiple PHGG trials (different brands) consistently show benefit. Mechanism: improved water-binding capacity in colon, gentle SCFA production.

IBS-D and IBS-C Symptom Improvement

PHGG paradoxically improves both diarrhea-predominant AND constipation-predominant IBS — normalizes stool consistency. Useful in mixed-pattern IBS.

Microbiome Support (Gentle Prebiotic)

Fermented in colon producing SCFAs and supporting beneficial bacteria, but fermentation is slower and gentler than FOS/inulin. Less gas production. Suitable for sensitive digestive systems.

Glycemic and Satiety Effects

Soluble fiber slows gastric emptying and modestly attenuates postprandial glucose. Mild satiety enhancement.

Mechanism of action

1

Partial Hydrolysis Reduces Viscosity

Native guar gum has VERY HIGH viscosity (creates thick gel) — unsuitable for many applications and harsh on GI. PARTIAL HYDROLYSIS reduces molecular weight and viscosity, making PHGG palatable and tolerable while preserving fermentation/prebiotic effects.

2

Slow, Gentle Colonic Fermentation

PHGG ferments slowly across entire colon; produces SCFAs (acetate, propionate, butyrate) gradually. Slow fermentation = less gas/bloating than FOS/inulin which ferment rapidly in proximal colon.

3

Bifidogenic and Lactobacillus-Supportive

Increases Bifidobacterium and Lactobacillus populations. Less specific bifidogenic effect than GOS, but broad microbiome benefit.

4

Stool Bulking and Hydration

Soluble fiber binds water in colon — softens hard stools (constipation) and binds excess water in loose stools (diarrhea). Normalizes stool consistency.

About this ingredient

About the active ingredient

FIBALANCE® is a PARTIALLY HYDROLYZED GUAR GUM (PHGG) prebiotic fiber developed by ZYMEBASE INC. (China; PCT/CN2023/095287 patent application) and distributed in the US by ECA HEALTHCARE. Native guar gum is a galactomannan fiber from the GUAR BEAN (Cyamopsis tetragonoloba); partial hydrolysis reduces molecular weight/viscosity while preserving prebiotic properties.

KEY DISTINCTION: LOW FODMAP CERTIFIED by MONASH UNIVERSITY — most prebiotic fibers (FOS, inulin, GOS) are HIGH FODMAP and worsen IBS symptoms; PHGG is the major IBS-friendly fiber option. RELATIONSHIP TO SUNFIBER: Sunfiber® (Taiyo, Japanese) is the original/most clinically-studied PHGG; Fibalance is a competitor product with similar core mechanism. Both are PHGG; differ in supplier, manufacturing process, and specific clinical evidence.

EVIDENCE-BASED USES: (1) IBS-FRIENDLY FIBER (foundational positioning); (2) Constipation relief; (3) IBS-D and IBS-C symptom improvement; (4) Gentle prebiotic microbiome support; (5) Glycemic attenuation; (6) Satiety enhancement.

CRITICAL CAUTIONS: (1) IBS POPULATIONS — PHGG is one of FEW prebiotics safe for IBS; major advantage; (2) GUAR/LEGUME ALLERGY — guar is legume; possible cross-reactivity with peanut/soy/legume allergies; rare; (3) DOSE — 5-10 g/day; can be taken at any time of day; mix in water/beverage; (4) HYDRATION — adequate water important with any fiber; (5) PREGNANCY/LACTATION — generally safe; widely used; (6) CHILDREN — safe at appropriate proportional doses; (7) PHGG VS OTHER FIBERS — PHGG superior to FOS/inulin for IBS, sensitive guts; PHGG less bifidogenic than GOS for infant applications; PHGG less viscous than psyllium so different physical properties; (8) SUNFIBER VS FIBALANCE — similar core ingredient; Sunfiber has more clinical trial history; choice based on availability, cost, formulation; (9) MICROBIOME EFFECTS — Fibalance increases Bifidobacterium and Lactobacillus; modest beneficial bacteria expansion; (10) APPLICATIONS — beverage/powder format common; mixes clear in water; tasteless; ideal for functional foods and supplements; (11) FOR REGULARITY — PHGG is among the most reliable fibers for both constipation and loose stools — regulates rather than just adds bulk; (12) ECA HEALTHCARE distributes Fibalance in US market; ZymeBase manufactures; verify product specifications.

Side effects and drug interactions

Common Potential side effects

EXCELLENT GI TOLERABILITY — distinguishes from other fibers.
Mild initial bloating with rapid introduction.
Headache rare.
Allergic reactions to legumes possible (guar bean is legume).
Esophageal obstruction risk if taken without adequate water (any fiber).

Important Drug interactions

Fiber supplements may delay absorption of medications — separate by 1-2 hours.
Diabetes medications — modest hypoglycemic effects from gastric emptying delay.
Cholesterol medications — modest additive lipid effects.
Pregnancy/lactation — generally safe; widely used in food applications.
Children — safe at appropriate doses.
