Evidence supporting the use of: Zinc
For the health condition: Diabetes
Synopsis
Source of validity: Scientific
Rating (out of 5): 2
Zinc has been investigated for its potential role in supporting diabetes management due to its involvement in insulin synthesis, storage, and secretion. Several observational studies have shown that people with diabetes often have lower zinc levels than healthy controls. Experimental and clinical studies suggest that zinc may improve glycemic control, possibly by enhancing insulin action and reducing oxidative stress. Small randomized controlled trials have reported modest reductions in fasting blood glucose and HbA1c with zinc supplementation, particularly in populations with zinc deficiency. However, the size and quality of these studies vary, and results are not uniform across all trials. The American Diabetes Association and other major guidelines do not currently recommend zinc supplementation for diabetes management except in cases of confirmed deficiency.
Traditional medical systems have not strongly emphasized zinc, but scientific interest persists due to biological plausibility and some supporting data. The overall evidence is rated as 2/5: there is some scientific support for zinc’s potential benefit in glycemic control, but the findings are not robust or consistent enough to justify routine use. More large-scale, high-quality studies are needed to clarify the efficacy and safety of zinc supplementation in diabetes beyond correcting deficiency.
