Listing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.

Background reading
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 1 g of turmeric / curcumin per serving. Studies we found used 500 mg–2 g a day, so this sits inside that range.
0studied 500 mg–2 g
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
