This is a randomized controlled trial (RCT) to compare the Meru Health Program plus adjunctive curcumin (MHP-CUR) versus Meru Health Program only (MHP-ONLY) for adults with depression. Meru Health is a 12-week integrative treatment program based on several evidence-based practices and overseen by licensed clinical therapists that is delivered via a Smartphone app. The primary objective of the study is to determine the feasibility, initial efficacy (depressive symptoms), and potential harms of taking adjunctive curcumin supplementation during the 12-week MHP among adults with depression. Secondary objectives include comparing changes in inflammation biomarkers, anxiety, worker productivity, and burnout that occur during the program between those in MHP-CUR and MHP-ONLY.

This feasibility study will use a randomized controlled trial of up to 60 adult patients with depression. Patients will be recruited through Facebook ads, complete online and telephone/Zoom screening and, if eligible, invited to participate in the 12-week Meru Health program. One group will be randomized to being in the MHP plus receiving curcumin supplementation (MHP-CUR) and the other will be randomized to being in the MHP only (MHP-only). The MHP overseen by a licensed therapist who is available to the participant as needed via text messaging and, when requested, telephone. The program is delivered via an app downloaded to the user's Smartphone made available via email. The lab orders will be sent to each patient's Ultalabs center of choice or, if preferred, done in the patient's home. All study participants (in both groups) will be asked to get their blood drawn before starting the program, 6 weeks into the program, and just after the 12-week program. Two vials of blood will be taken at each visit, one to test for high sensitivity-CRP (hs-CRP) levels and the other to test for interleukin (IL-6) levels. 2ml of serum is needed for each vial. Patients in both groups will receive a wearable HRVB device via US mail; patients in the MHP-CUR group will also receive curcumin supplements via US mail. All non-laboratory study assessments will be made via the app and online via email.
