Is Lactulose Vegan?
AvoidNo. Lactulose, used to treat constipation, is a synthetic sugar that occurs when milk is heated.
Lactulose and the Vegan Diet
Lactulose is a synthetic disaccharide sugar composed of galactose and fructose. It is produced from lactose, a sugar found in milk, through a heating process. Although derived from a milk sugar, lactulose itself is not absorbed in the small intestine. Instead, it reaches the colon where it is broken down by bacteria, leading to increased water content in the bowel and softer stools, thus alleviating constipation. Lactulose is commonly used in medical settings to treat constipation and hepatic encephalopathy.
