Does curcumin lower blood pressure?

Two randomized controlled trials (RCTs) investigating the effects of curcumin supplementation on blood pressure did not find significant improvements. In the first study, which involved individuals with metabolic syndrome and used nanomicellar curcumin, no significant changes in blood pressure were observed.^[1] The second RCT, which was small in size and included people with obesity, used curcumin formulated with fenugreek soluble fiber. Similar to the previous study, this trial also did not find any improvements in blood pressure following curcumin supplementation.^[2] These findings suggest that curcumin supplementation alone, as well as in combination, may not effectively reduce blood pressure in people with metabolic syndrome or obesity.
