An interventional study of vitamin D supplement and Placebo in Depression, sponsored by Tirang R. Neyestani, Ph.D.. Status unknown at 1 site in Iran, Islamic Republic of. Open to participants aged 18 Years to 60 Years. Per ClinicalTrials.gov, last updated 2018-12-13.

Groups (intervention group receives 50000 IU vitamin D and control group receives placebo) through a random allocation. After 8 weeks, blood sample will be collected from each participant. The studied indices (inflammatory (IL-1β, IL-6, hs-CRP), PTH, platelet serotonin, serum oxytocin, serum 25(OH) D, depression status and anthropometry indices) will be evaluated at beginning and end of interventional period.
In this double-blind randomized clinical trial, 60 patients aged 18-60y referred to Baharlou hospital with a history of mild to moderate depression diagnosed by a psychiatrist will be presented to the researcher. After receipt of a signed informed consent form, eligible patients will participate. A general demographic questionnaire will be completed by an interviewer. Individuals are randomly divided into intervention and control groups. A 10-ml venous blood sample will be collected from each participant. The intervention group receives 50000 IU of vitamin D every 2 weeks as vitamin D supplements for 8 weeks, provided monthly. The control group receives placebo. The drug schedule of both groups (if any) will be unchanged according to the prescribing physician. After 8 weeks, blood sample will be collected from each participant. The studied indices (inflammatory (IL-1β, IL-6, hs-CRP), PTH, platelet serotonin, serum oxytocin, serum 25(OH) D, depression status, anthropometry indices) will be evaluated at beginning and end of interventional period. Data will be analyzed by statistical tests.
