Uses & Effectiveness ?

Insufficient Evidence for

  • 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.
