Carbohydrolytic

alpha-Galactosidase

Catalyzes the removal of terminal α-1,6-linked galactose residues from complex oligosaccharides such as raffinose, stachyose, and verbascose. These carbohydrates, commonly found in beans and cruciferous vegetables, often escape digestion and undergo fermentation in the colon, producing gas. By breaking them down earlier in the digestive process, alpha-galactosidase reduces the potential for fermentation-related discomfort.*

BIOCHEMICAL ROLE IN DIGESTION

Alpha-galactosidase hydrolyzes terminal α-1,6-linked galactose residues found in oligosaccharides such as raffinose and stachyose, common in beans, legumes, and cruciferous vegetables. These carbohydrates are otherwise resistant to human digestive enzymes and often reach the colon intact, where they undergo microbial fermentation. By cleaving their galactose residues, alpha-galactosidase prevents excessive gas formation, reduces intestinal distention, and improves carbohydrate digestibility in fiber- and legume-rich diets.*

NUTRITIONAL RELEVANCE IN SUPPLEMENTATION

Supplemental alpha-galactosidase provides significant relief for individuals who experience gas and bloating after consuming beans, lentils, or cruciferous vegetables. By breaking down raffinose-family oligosaccharides before they reach colonic bacteria, supplementation reduces fermentation-related discomfort and enhances nutrient access. This enzyme broadens dietary tolerance, enabling individuals to enjoy nutrient-rich, plant-based foods without gastrointestinal side effects, thereby supporting better adherence to high-fiber, legume-inclusive diets.*
