Brief Summary
The current study is designed as a prospective partially randomized patient preference (PRPP) trial and recruit psychiatric outpatients or inpatients. Participants who agree to receive randomization will be randomly assigned into a supplementation or placebo group, after stratification for pre-intervention vitamin D status (12-20 ng/mL or \<12 ng/mL) and depression status (HDRS-17 ≥ 17 or \< 17). Participants who decline randomization but agree to receive follow-up in the observational cohort choose their preferred method (either 4800 IU vitamin D3 per day, or usual care without supplementation). Severity of depression, any change of medication, and side effect will be assessed at baseline and at 2-week intervals for 8 weeks. Serum levels of 25(OH)D, C-Reactive protein (CRP) and 12 cytokines, anthropometrical measurements, dietary intake, physical activity and sun exposure will be assessed at baseline and post-intervention. Additionally, serum levels of 25(OH)D will be assessed at 4 weeks to ensure its safety level.

Outcome Measures
Primary Outcomes (1)
Change of total score of 17-item Hamilton Depression Rating Scale (HDRS-17)
17-item Hamilton Depression Rating Scale is an interview-based instrument for rating the overall levels of severity of the symptoms of depression and the response to treatment. Each item is rated from 0 to 4 or 0 to 2; the scores correspond to increases in severity. Total scores range from 0 to 52.
