Benefits
FODMAP Fructan Digestion Support
Fructanase specifically targets FRUCTANS — the 'F' in FODMAP — found in garlic, onions, wheat, asparagus, artichokes; common cause of IBS-like GI symptoms.
Reduces GI Discomfort from Fructan Foods
Designed for those with sensitivity to fructan-containing foods experiencing bloating, gas, abdominal discomfort.
XOS (Xylooligosaccharide) Production
BIO-CAT R&D found Fructanase breaks down fiber-rich foods into XOS — beneficial prebiotic. Dual benefit: digestion support AND prebiotic generation.
IBS Dietary Management Adjunct
Useful for those managing IBS via low-FODMAP diet who experience accidental exposure or want flexibility.
Vegetable Fructan Support
Recent research shows Fructanase may promote digestion of fructans from vegetables — relevant to plant-rich diets.
Unique Mechanism
Distinguished from broad-spectrum protease/amylase blends — specifically targets fructan oligosaccharides.
Mechanism of action
Fructan Hydrolysis
Fructanase cleaves fructose-fructose bonds in fructan oligosaccharides — converts indigestible FODMAP fructans to absorbable simple sugars or beneficial XOS.
XOS Generation
Selective hydrolysis produces xylooligosaccharides — beneficial prebiotic that supports beneficial gut bacteria including Bifidobacterium.
FODMAP-Targeted Action
Specific activity against fructans (vs broad-spectrum enzymes) targets a major IBS trigger.
Clinical trials
BIO-CAT R&D research on Fructanase for fructan digestion and XOS generation.
In vitro and clinical evaluations.
Established fructan digestion support and XOS generation.
About this ingredient
OPTIZIOME® FRUCTANASE® is a SPECIFIC FRUCTAN-DIGESTING ENZYME developed by BIO-CAT. FODMAP BACKGROUND: FERMENTABLE OLIGOSACCHARIDES, DISACCHARIDES, MONOSACCHARIDES, AND POLYOLS — short-chain carbohydrates poorly absorbed by some people; fermentation in colon causes IBS-like symptoms; FODMAPs include FRUCTANS (Fructanase target), galactans, lactose, fructose, sorbitol/mannitol. FRUCTAN SOURCES: garlic, onions, wheat, rye, artichokes, asparagus, leeks, etc.
KEY DISTINCTIONS: (1) FODMAP-SPECIFIC enzyme targeting fructans; (2) XOS prebiotic generation; (3) BIO-CAT R&D backing; (4) Unique among digestive enzymes.
EVIDENCE-BASED USES: (1) FODMAP fructan food digestion; (2) IBS dietary management adjunct; (3) Garlic/onion/wheat tolerance support; (4) Vegetable fructan digestion; (5) XOS prebiotic generation.
CRITICAL CAUTIONS: (1) IBS COMPREHENSIVE MANAGEMENT — Fructanase is one tool; comprehensive IBS care includes: dietary modification (low-FODMAP elimination then reintroduction), stress management, possibly probiotics, possibly medications; (2) DOSE — per BIO-CAT specification; typically with fructan-containing meals; (3) CELIAC DISEASE NOT THE SAME — Fructanase addresses fructans (carbohydrate); celiac is gluten (protein); different conditions; for celiac-related wheat avoidance, GluteAX more relevant; (4) NOT A CURE — Fructanase supports digestion but does not eliminate underlying FODMAP sensitivity; comprehensive approach important; (5) FRUCTANASE vs BROAD-SPECTRUM ENZYMES — broad blends may include some fructanase but Optiziome Fructanase is specific concentrated form; (6) FOR LOW-FODMAP DIETERS — Fructanase enables flexibility when occasional fructan exposure is desired or unavoidable; (7) BRAND VERIFICATION — Optiziome® and Fructanase® are BIO-CAT trademarks; (8) Among the more specialized digestive enzymes for specific FODMAP applications.
