Supporting research

Ingredient research

Moderate human evidence

Systematic reviews of randomised trials report that curcumin or turmeric supplements may improve some metabolic and inflammatory markers, but results and evidence quality vary. Trials generally use concentrated or enhanced-bioavailability products, not ordinary culinary turmeric, so supplement findings should not be presented as benefits of a spoonful used in food.
