Alpha Galactosidase Uses: An Overview of the Enzyme and Its Benefits1

Alpha galactosidase is an enzyme that is naturally produced in the human body, as well as in some bacteria and fungi. This enzyme plays an important role in breaking down complex carbohydrates, specifically those containing alpha-galactosidic bonds. In recent years, alpha galactosidase has gained attention for its potential health benefits, particularly in the area of digestive health. In this article, we will explore the various uses of alpha galactosidase and its benefits.

Alpha galactosidase is an enzyme that breaks down complex carbohydrates containing alpha-galactosidic bonds. These bonds are found in foods such as beans, legumes, and cruciferous vegetables, which can be difficult to digest for some people. Alpha galactosidase is naturally produced in the human body, specifically in the pancreas and small intestine, but can also be found in some bacteria and fungi.

How Does Alpha Galactosidase Work?

When we eat foods that contain alpha-galactosidic bonds, our bodies need to break down these complex carbohydrates into simpler sugars that can be absorbed and used for energy. This is where alpha galactosidase comes in. Alpha galactosidase breaks down the alpha-galactosidic bonds, making the complex carbohydrates easier to digest and absorb.

Uses of Alpha Galactosidase

Fabry Disease

Fabry disease is a rare genetic disorder that affects approximately 1 in 40,000 individuals worldwide. It is caused by a deficiency of alpha galactosidase A enzyme activity, leading to the accumulation of a specific type of lipid called globotriaosylceramide (Gb3) in various organs of the body, including the kidneys, heart, and nervous system.

Alpha galactosidase replacement therapy (AGRT) is the primary treatment for Fabry disease. This therapy involves the administration of a synthetic form of alpha galactosidase A enzyme to replace the missing or deficient enzyme in the body. AGRT has been shown to reduce the accumulation of Gb3 in various organs, improve kidney function, and decrease pain in individuals with Fabry disease.


Flatulence, also known as passing gas, is a common digestive issue that affects many individuals. It is caused by the fermentation of undigested carbohydrates in the large intestine by gut bacteria, leading to the production of gas. Alpha galactosidase supplements are often used as a dietary supplement to reduce flatulence and bloating caused by the consumption of complex carbohydrates, such as beans and legumes.

Other Uses

Aside from Fabry disease and flatulence, alpha galactosidase has potential uses in various other medical conditions, including:

  • Galactosialidosis: A rare genetic disorder characterized by a deficiency of alpha-neuraminidase and alpha galactosidase enzymes.

  • Hirschsprung's disease: A congenital disorder characterized by the absence of ganglion cells in the colon, leading to chronic constipation and other digestive issues.

  • Infantile krabbe disease: A rare and fatal genetic disorder that affects the nervous system.

  • Type 2 diabetes: Some studies suggest that alpha galactosidase may improve glycemic control in individuals with type 2 diabetes by reducing postprandial hyperglycemia.

Health benefits of alpha galactosidase

Digestive health

Alpha galactosidase is commonly used as a digestive aid, as it helps to break down complex carbohydrates that are difficult to digest. This can improve overall digestive health, as well as reduce symptoms of digestive disorders such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD).

Reduces gas and bloating

One of the primary benefits of alpha galactosidase is its ability to reduce gas and bloating. Complex carbohydrates such as raffinose and stachyose are known to cause gas and bloating, particularly in people with digestive disorders. Alpha galactosidase breaks down these complex carbohydrates, reducing the amount of gas and bloating in the digestive system.

Reduces inflammation

Alpha galactosidase has been shown to have anti-inflammatory properties, which can help to reduce inflammation in the body. Chronic inflammation has been linked to a number of health problems, including heart disease, diabetes, and cancer.

Lowers risk of heart disease

Alpha galactosidase has been shown to lower the risk of heart disease by reducing levels of LDL (bad) cholesterol in the blood. High levels of LDL cholesterol are a major risk factor for heart disease.

In conclusion, alpha galactosidase is an essential enzyme that plays a vital role in breaking down complex carbohydrates in the body. Its uses in the medical field are primarily focused on the treatment of Fabry disease and reducing flatulence. However, ongoing research suggests that alpha galactosidase may have potential uses in various other medical conditions, including galactosialidosis, Hirschsprung's disease, infantile krabbe disease, and type 2 diabetes.
