Curcumin administration significantly reduces blood glucose levels and improves insulin sensitivity in rodent models of diabetes (STZ-induced, alloxan-induced, and high-fat diet-induced).
In animal studies, curcumin consistently lowered blood sugar and improved insulin sensitivity across various diabetes models. While human data is limited, the mechanism suggests potential benefit for glycemic control, particularly when using formulations designed to improve absorption.

oral administration of various dosages of curcumin... were able to prevent body weight loss, reduce the levels of glucose, hemoglobin (Hb), and glycosylated hemoglobin (HbA1C) in blood [15], and improve insulin sensitivity [16].
Why this rating
The paper is a systematic review of animal studies and a few small clinical trials; no large-scale human RCTs are the primary focus.
