Medical students and residents have high rates of mental distress and burnout related to the intellectual and time demands of their training. Research shows that physiological stress on the body can be a result of fatigue and high stress work, and is associated with experiences related to mental distress. Pomegranate is a fruit that is known to contain a variety of antioxidant substances that can reduce physiological stress. This study will look at the potential for pomegranate supplementation to reduce physiological stress and improve well-being in medical students and residents.
This is a pilot study to investigate the feasibility of conducting a randomized trial of pomegranate supplementation in medical students and residents, and to see whether there is evidence of an effect on reported emotional and physical well-being. Phase 1 will be a pilot with 10 participants in which all will receive the pomegranate supplement for 28 days. In phase 2, we will randomize 40 participants (1:1) to receive either the pomegranate supplement or a placebo. For both phases, we will measure self reported emotional and physical well-being using several questionnaires, and we will conduct laboratory testing for measures of oxidative stress and inflammatory biomarkers in blood, and for a metabolite of pomegranate in urine.
