About Kristalose

What is Kristalose?

Kristalose is a synthetic sugar prescribed to treat constipation as well as to reduce ammonia in the blood of patients with liver disease. In the colon, for those with constipation, it breaks down into components that draw water from the body into the colon to soften stools; for those with liver disease it extracts ammonia from blood in the colon for removal.
