DigeZyme® (Sabinsa Corporation) is a broad-spectrum multi-enzyme complex containing five key digestive enzymes — alpha-amylase (starch), protease (protein), lipase (fat), cellulase (plant fiber), and lactase (milk sugar) — produced via non-GMO fungal and bacterial fermentation to be stable across the wide pH range of the GI tract. As a comprehensive digestive support ingredient, DigeZyme® improves macronutrient absorption, reduces post-meal digestive discomfort, and supports optimal nutrient bioavailability across all major food groups.

Studied Dose 50–150 mg/day DigeZyme® (providing standardized enzyme activity); taken with meals for optimal effect; dose adjusted based on meal composition

Comprehensive macronutrient digestion support

DigeZyme® provides the full enzymatic toolkit to digest all major macronutrients: amylase for starches and complex carbohydrates, protease for dietary proteins, lipase for fats and oils, cellulase for plant fiber cell walls, and lactase for milk sugar — supporting complete nutrient breakdown and absorption from varied diets.

Reduced digestive discomfort and bloating

Clinical studies show DigeZyme® significantly reduces post-meal bloating, flatulence, abdominal discomfort, and feelings of heaviness — particularly after high-protein, high-fat, or high-fiber meals. By ensuring complete macronutrient digestion in the small intestine, less undigested substrate reaches the colon where fermentation causes discomfort.

Improved protein absorption and muscle recovery

A human RCT demonstrated DigeZyme® supplementation significantly improved protein absorption markers, reduced post-exercise muscle soreness, and accelerated recovery when taken alongside protein supplementation. The protease activity specifically enhances dietary protein bioavailability for muscle protein synthesis.

Lactose intolerance support

The lactase enzyme in DigeZyme® hydrolyzes lactose into glucose and galactose before it reaches the colon, preventing the fermentation-driven gas, bloating, and diarrhea experienced by lactose-intolerant individuals consuming dairy products. This targeted enzyme activity allows lactose-sensitive individuals to consume dairy-containing foods and supplements.

Nutrient bioavailability enhancement

Complete enzymatic breakdown of food matrices releases bound micronutrients (vitamins, minerals) from food structures, improving their bioavailability for absorption. This nutrient-releasing effect complements direct digestion support, ensuring optimal nutritional value from both food and supplement sources.

1

pH-stable enzyme activity across GI tract

DigeZyme® enzymes are produced from Aspergillus and other fungal sources specifically for their stability across the wide pH range of the GI tract (pH 2–8). Unlike pancreatic enzymes that function optimally at pH 7–8, DigeZyme® maintains activity from the acidic stomach through the alkaline small intestine, providing digestion support throughout the entire GI transit.

2

Substrate-specific hydrolytic activity

Each enzyme component specifically targets its substrate: alpha-amylase cleaves alpha-1,4-glycosidic bonds in starch, protease cleaves peptide bonds, lipase hydrolyzes ester bonds in triglycerides, cellulase cleaves beta-1,4-glycosidic bonds in cellulose, and lactase cleaves beta-galactosidic bonds in lactose. This substrate specificity ensures comprehensive digestion without interfering with normal GI physiology.

3

Pre-colonic digestion completion

By completing macronutrient hydrolysis in the small intestine, DigeZyme® reduces the amount of undigested carbohydrate, protein, and fat reaching the colon. Less colonic fermentation substrate means reduced gas production, shorter GI transit time, and reduced exposure of the colonic epithelium to potentially irritating fermentation byproducts.

DigeZyme® and Post-Exercise Muscle Recovery — RCT
PubMed

Randomized, double-blind, placebo-controlled trial of DigeZyme® combined with whey protein vs. whey protein alone in 20 trained men for 4 weeks of resistance training.

20 resistance-trained men. 4-week training study.

DigeZyme® + whey protein significantly reduced DOMS (muscle soreness), creatine kinase levels, and recovery time vs. whey alone. Greater improvements in strength recovery between sessions. Confirmed improved protein absorption from enzyme supplementation.

Multi-enzyme Complex and Digestive Comfort — Clinical Study
PubMed

Clinical study examining multi-enzyme complex supplementation effects on post-meal digestive symptoms in adults with functional digestive complaints.

Adults with functional digestive complaints. 4-week supplementation study.

Multi-enzyme supplementation significantly reduced post-meal bloating, flatulence, abdominal discomfort, and feelings of fullness. Improvements in overall digestive comfort and quality of life. Well-tolerated with no adverse effects.

Common Potential side effects

Generally very well tolerated; enzyme supplements have extensive food use history
Very rare allergic reactions in individuals with mold/fungal allergies (Aspergillus-derived enzymes)
High doses may cause mild GI discomfort; standard doses well-tolerated

Important Drug interactions

Anticoagulants (warfarin) — proteases may theoretically affect drug metabolism; monitor at very high enzyme doses
Blood sugar medications — amylase activity reduces starch digestion rate; may mildly affect postprandial glucose; monitor in diabetics on tight glycemic control
No clinically significant drug interactions established at standard supplement doses
