Official title

Randomized, Controlled Trial of Vitamin D Replenishment in Metabolic Syndrome

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Vitamin D deficiency is widespread and appears to represent one easily and inexpensively modifiable risk factor for diabetes and cardiovascular disease. More than 40 years of data link hypovitaminosis D to metabolic syndrome, insulin resistance, hyperglycemia, type 2 diabetes and increased cardiovascular risk. Screening for vitamin D deficiency followed by supplementation in appropriate individuals could be among the simplest and most cost-effective measures for reducing metabolic syndrome and insulin resistance in the general population. This study will test the hypothesis that increasing vitamin D status in vitamin D deficient individuals with metabolic syndrome will: 1. reduce multiple serum cardiometabolic risk factors for both diabetes and cardiovascular disease, 2. stabilize or reverse the stage of pre-diabetes, 3. improve quality of life, and, 4. improve the ability to make health-related behavioral changes.
