Brief Summary:
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)

Condition or disease Intervention/treatment Phase
Vitamin D3 Gestational Diabetes Mellitus in Pregnancy Dietary Supplement: Vitamin D3 Other: Capsules with placebo (talcum food grade) Phase 3

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.
