Turmeric supplementation complementary treatment managing disturbed glycemia

For this purpose, the researchers systematically searched the major online databases from inception up to October 2022. The researchers included relevant RCTs meeting the eligibility criteria. Weighted mean differences (WMDs) were expressed using a random-effect model. To determine the sources of heterogeneities, they conducted subgroup analyses. The Cochrane risk-of-bias tool was used to detect the risk of bias in the included studies.

The authors reported the following findings:

• Out of 4182 articles retrieved from the initial search, 59 RCTs were included.
• The findings suggested that turmeric/curcumin supplementation was significantly effective in improving fasting blood sugar (WMD: 4.60 mg/dl), haemoglobin A1c (HbA1c) (WMD: 0.32%), fasting insulin levels (WMD: 0.87 μIU/ml), and homeostatic model assessment of insulin resistance (HOMA-IR) (WMD: 0.33).

"Our results indicate that supplementation with turmeric/curcumin can be considered a complementary method in managing disturbed glycemia," the researchers concluded.
