This clinical trial is aimed at measuring the effect of vitamin D3 supplementation on serum prostate-specific antigen (PSA) levels in patients diagnosed with early stage, low-grade, low-risk prostate cancer (Gleason score less than/equal to 6; PSA less than/equal to 10; clinical stage T1C or T2a), who elect to have their disease monitored through active surveillance for at least one year.
Control: Active Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
