Regularly updated with revitalising boosts of fresh data.

UPDATED April 2019: Promising new evidence boosts garlic as a treatment for cancer, wholegrains for diabetes, and agnus castus for PMS. Several new entries, including turmeric and saffron for depression, and zinc, which appears to protect kids from pneumonia. Downgraded: SAMe for depression and vitamin K2 for heart disease, both of which dropped several points.

UPDATED July 2018: New entries include melatonin for sleep and Vitamin D for flu, bones and long life. Downgrades for valerian as a cure for anxiety and cranberry juice for urinary infections. New entries for harmful supplements, including Vitamin A, which has been linked to birth defects.

Note: You might see multiple bubbles for certain supplements. These is because some supps affect a range of conditions, but the evidence quality varies from condition to condition. For example, there’s strong evidence that garlic can lower blood pressure. But studies on whether it can prevent colds have produced inconclusive results. In these cases, we give a supp another bubble.
