Vitamin D plays a role in glucose metabolism through modulation of insulin sensitivity and anti-inflammatory effects, but the relationship between vitamin D and HbA1c still shows varied results.
Objective: This review aims to analyze the effect of vitamin D on HbA1c levels in T2DM patients based on published studies.
