Anhydrous crystalline maltose is a molecule called a disaccharide. It is formed by the joining of two glucose (sugar) molecules.

  • An autoimmune disorder in which the glands that produce tears and saliva are damaged (Sjogren syndrome). Early research suggests that dissolving lozenges of anhydrous crystalline maltose in the mouth three times daily for up to 24 weeks improves saliva output in people with Sjogren syndrome.
  • Dry mouth due to prescription medicines.
  • Other conditions.
More evidence is needed to rate the effectiveness of anhydrous crystalline maltose for these uses.
