What the science says
Yes - curcumin, the active compound in turmeric, lowers markers of inflammation in the blood, based on a 2023 analysis pooling results from 66 human trials. That analysis found consistent reductions in CRP (C-reactive protein, a blood marker that rises when the body is inflamed) and two immune-signalling proteins called TNF-alpha and IL-6, which help trigger and coordinate inflammation. Smaller studies add support for specific situations, including exercise-related muscle soreness in people and inflamed kidneys in mice, though how much curcumin the body actually absorbs remains debated.
Full analysis
The strongest evidence is a 2023 analysis pooling 66 randomised trials in adults (trials where participants were randomly assigned to curcumin or a comparison group), which found that curcumin or turmeric supplementation consistently lowers CRP, TNF-alpha and IL-6 - three markers doctors use to gauge inflammation in the blood.
Two smaller studies add supporting detail rather than independent proof. A review of curcumin after exercise-induced muscle damage found it reduced soreness and lowered several of the same inflammatory proteins in people who had exercised hard. A study in mice with high uric acid levels (a condition linked to gout) found curcumin reduced kidney inflammation by blocking a molecular trigger for inflammation.
The main analysis covers general adult populations, not people with a specific disease, so it says less about inflammation tied to a particular illness. The mouse study does not establish that the same kidney effect happens in humans.
Taken together, the human trial evidence for lowering general inflammatory markers is solid, though how much curcumin the body absorbs remains debated.

In people recovering from strenuous exercise, curcumin supplementation reduced muscle soreness, raised antioxidant levels, and lowered inflammation-signalling proteins including TNF-alpha, IL-6 and IL-8.

In mice with high uric acid levels (a condition linked to gout), curcumin reduced kidney inflammation by lowering inflammatory signalling proteins and blocking a cell structure called the NLRP3 inflammasome, which switches on the inflammatory response.
