Big effect
Curcumin showed a huge effect on rheumatoid arthritis response in a meta-analysis — but the evidence behind that number is rated very low certainty.
This is an early, promising signal from a small set of trials, but the evidence is too shaky to act on — larger, more rigorous studies are needed before anyone should change their treatment plan.
A meta-analysis of 6 small trials found that curcumin improved the ACR20 response — a standard measure of rheumatoid arthritis improvement — by a very large amount. However, the same analysis rated the evidence certainty as 'very low,' meaning the studies had serious flaws, and the results could easily flip with better research.
Where this fits in the evidence
This is among the first studies we've indexed on Turmeric for Improved ACR20 Response — treat it as an early signal until more research accumulates.
