Brief summary
The study will assess the effects of a nutrient supplement (nutraceutical) combination in individuals with treatment-refractory obsessive-compulsive disorder. The study is a 5 month, open-label, multicentre pilot study.
Interventions
All enrolled participants will receive the following nutrient supplements for the 20 weeks of the study: *Compounded N-acetylcysteine (NAC) and L-theanine (LT) capsules, 500mg and 100mg per capsule respectively. Two capsules taken twice per day (2,000mg NAC and 400mg LT per day). Dose will be titrated to three capsules, twice per day in cases of non-response from Week-8 in the study (non-response defined as < 35% reduction in Week-8 Y-BOCS score in comparison to baseline). *Zinc liquid (25 drops per day, 28.4mg elemental zinc per day) *Selenium liquid (5 drops per day, 113mcg elemental selenium per day) *Magnesuim and Vitamin B6 tablets (1 tablet per day, 150 elemental magnesium, 50mg pyridoxal-5-phosphate). Participants will be asked to return their nutrient supplements at each follow-up visit where capsules/tablets will be counted, and liquid measured to determine compliance. New supplements will be dispensed at each visit as required.
