The proposed study is a 60-day, randomized, double-blind, placebo-controlled trial to evaluate the efficacy of a methylated vitamin B complex nutritional supplement (Max Stress B™) for improving depressive and anxiety symptoms according to the Beck Depression and Anxiety Inventories, respectively, in 60 patients (18+ years of age) diagnosed with major depression or other forms of depressive disorders and an elevated level of homocysteine (> 10 µmol/L) at baseline. Secondary outcomes will include anthropometrics for body composition, blood pressure and pulse, level of physical activity, dietary intake, and quality of life. Participants will be assessed at baseline and 30 and 60 days. The study will consist of two treatment arms: (a) vitamin B complex nutritional supplement and (b) placebo.

The information obtained in this study will help in determining the efficacy of using nutritional supplements for improving the outcomes of people with depression.

Primary Outcome Measures:
  • Depression level [ Time Frame: 2 months ]

    Assessed by the Beck Depression Inventory II, the Beck Anxiety Inventory, SF-36v2™ Health Survey, physiological and anthropometric measures

    Because item 9 of the Beck Depression Inventory inquires about "Suicidal thoughts or wishes," we will immediately notify the attending physician in the Crisis facility of UM/JMH if a subject responds affirmatively to this question, which may be indicative of suicidal ideation (SI).
