What research says

Studies in people

  • Open question

    Digestive enzyme disorders2

    In some people, not having enough of the enzyme that breaks down maltose can cause problems.

  • Open question

    Fuel use during exercise3

    In people, maltose during long cycling raised carb burning and spared the body's own carb stores.

  • Open question

    Exercise performance4

    Maltose drinks kept blood sugar higher, but no clear difference in exercise performance was found.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.
