This is a randomized clinical trial (RCT) to determine the effectiveness of vitamin D3
supplementation on depressive symptoms, self-management, and blood pressure in approximately
180 adult women with type 2 diabetes who have significant depressive symptoms. Consenting
adult women who are eligible to participate will be randomly assigned to either a weekly dose
of 50,000 international units of vitamin D3 supplementation or a matching weekly active
comparator of 5,000 international units of vitamin D3 for six months. Participants will
complete approximately four in-person study visits and several telephone visits throughout
the six month trial period, where the researchers will assess depressive symptoms, diabetes
self-management, and systolic blood pressure.
