About this study

Official title: Effect of Suplementation of 5,000 UI Vitamin D3 on the Glycemic Profile in Patients With Gestational Diabetes Mellitus of the Hospital Civil de Guadalajara Dr. Juan I. Menchaca

Randomized double-blind placebo-controlled clinical trial. Consists of the administration of 5,000 IU of vitamin D3 vs Placebo in patients with gestational diabetes mellitus during eight weeks. The objective is to analyze the effects of the intervention on the biochemical parameters that are part of the glycemic profile (insuline, HBA1c, glucose)

Read the detailed description

Two groups of patients diagnosed with gestational diabetes mellitus. Once the selection criteria are verified, they will be assigned randomly in one of the two arms,one of them will recive 5,000 IU of vitamin D and the other one placebo (talcum food grade). Baseline measurements of vitamin D, glucose,insulin, HBA1c, calcium, phosphorus. At the end of the eight weeks will be determined again the aforementioned biochemical parameters.

Being tested
Vitamin D3, Capsules with placebo (talcum food grade)

What participants receive
