What research says

Studies in people

  • Concern

    Liver injury from supplements3

    A woman who had turmeric-related liver injury before got sick again after restarting turmeric with black pepper.

  • Concern

    Liver health4

    In 2019, 28 people in Italy who took turmeric supplements reported sudden liver problems, which were possibly linked to the supplements.

  • Benefit

    Quality of life in cancer patients5

    In breast cancer patients on chemotherapy, turmeric improved quality of life and blood counts over 21 days.

Study type not stated

  • Concern

    capsule content and purity6

    Turmeric capsules varied widely in curcumin, and some contained trace metals like lead and nickel.

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 two findings in people. Findings whose study type is not stated are shown but not counted.
