Derived from nature
The disaccharide lactulose is an isomerisation product from lactose (galacto-glucose), a natural component of milk. It consists of the two monosaccharides galactose and fructose. The production process for lactulose was developed in our laboratories researching carbohydrates, and was patented in 1969.

Lactulose cannot be split by human enzymes present in the gut. Therefore it passes the stomach and small intestine and reaches the colon unchanged, where it is split by saccharolytic bacteria. The particularly gentle and natural laxative action of lactulose results from its prebiotic, osmotic, and peristalsis-activating effects.
