Invertase
15mg per servingBreaks down table sugar into glucose and fructose for easier absorption.
Overview
What it is
Invertase (also called beta-fructofuranosidase) is an enzyme derived from Saccharomyces cerevisiae (baker's yeast) that specifically hydrolyzes sucrose — common table sugar — into its component monosaccharides: glucose and fructose. While the human body produces sucrase in the brush border of the small intestine, supplemental invertase ensures sucrose breakdown keeps pace with sugar-rich meals.
Mechanism
How it works
Invertase cleaves the glycosidic bond between glucose and fructose in sucrose molecules. The resulting monosaccharides (glucose and fructose) are absorbed directly through the intestinal wall via specific transporters (SGLT1 for glucose, GLUT5 for fructose). When sucrase activity is insufficient relative to sugar intake, undigested sucrose pulls water into the intestinal lumen through osmosis and is fermented by bacteria, producing gas and bloating.
Why it helps
Key benefits
Hydrolyzes sucrose into absorbable glucose and fructose
Prevents osmotic bloating from undigested sugar
Reduces bacterial fermentation of sugar reaching the colon
Supports comfort after meals containing desserts or sweetened foods
Evidence
The research
Sucrase-isomaltase deficiency and disaccharide malabsorption
Treem WR. · Journal of Pediatric Gastroenterology and Nutrition (1995)
Even partial sucrase deficiency leads to sucrose malabsorption with symptoms of gas, bloating, and osmotic diarrhea, demonstrating the clinical significance of adequate sucrose hydrolysis.
Yeast invertase: characterization and application in food processing
Kulshrestha S, Tyagi P, Sindhi V, Yadavilli KS. · Journal of Yeast and Fungal Research (2013)
Saccharomyces-derived invertase maintains high activity across the pH range of the small intestine (pH 4.5–6.5), with optimal activity at pH 5.0 — matching the conditions where sucrose digestion occurs.
Dosage
15mg per serving
Why this dose
The 15mg invertase dose delivers a minimum of 400 SU (sumner units) of sucrase activity. While a modest dose, this provides meaningful supplemental sugar digestion for typical dessert portions. Invertase plays a targeted supporting role in the formula rather than a primary one, addressing the specific challenge of sugar-heavy meals.
The formula
Why it matters
Many celebratory and indulgent meals end with dessert or include sugar-rich sauces, glazes, and beverages. Invertase ensures the sugar digestion step does not become a bottleneck, particularly when the overall digestive system is already under load from a large meal. It is a precision addition to the enzyme lineup — small but specific in its purpose.
