Alpha-galactosidase is an enzyme, which is derived from the fungus Aspergillus niger. It’s a homodimeric glycoprotein and it hydrolyzes the terminal alpha-galactosyl moieties (in chemistry moiety is defined as a functional group on a molecule) from glycolipids and glycoproteins. These moieties are complex or branching sugars (polysaccharides and oligosaccharides) in legumes (beans, lentils, peanuts) and cruciferous vegetables (cabbage, broccoli, cauliflower, brussel sprouts).

The enzyme breaks down these complex sugars into simple sugars, which makes them more digestible. Otherwise,they would pass through the small intestine unaffected. In the large intestine the complex sugars may be metabolized by intestinal flora, fermenting them to produce gas.

Alpha-glactosidase is found in many enzyme supplements including Enzyme Gold®. It’s the main ingredient found in Beano® Food Enzyme Dietary Supplement Tablets. One Beano® tablet contains 150 GALU of alpha-galactosidase.

Beano® is swallowed, chewed or crumbled onto food and the typical dose is three tablets per meal. Don’t cook with Beano, as heat will deactivate it. Other foods besides those mentioned above that can benefit from the consumption of Beano are whole grains, pasta and onions.

In rare cases sensitivity to Beano® may occur, but it’s generally safe. Galactosemics should consult their doctor.
