Iranian research departments studied the effect of vitamin D3 on TNF-α, an inflammation parameter, in type 2 diabetic patients. 51 diabetic patients were involved in the study. 26 patients were orally supplemented with 400 IU/day (10 µg) vitamin D3 and 25 patients with a placebo for 14 weeks. Among others, long-term glucose levels (HbA1c), vitamin D3 levels and the mentioned inflammation parameter were measured at the start of the study and after the intervention period. TNF-α decreased significantly in the supplementation group. The researchers recommend taking vitamin D in type 2 diabetics. More details can be found in the study.
