Summary
This study tests whether weekly vitamin D supplements, adjusted to reach a specific blood level, can improve blood sugar control in 100 adults aged 30-74 with prediabetes. Participants are randomly assigned to vitamin D or placebo for 18 months, with dose adjustments based on blood tests. The main goal is to see if vitamin D increases the time blood sugar stays in a healthy range, potentially preventing type 2 diabetes.
