- University of Colorado, Colorado Springs
- Brief Summary
The purpose of this study was to compare the impact of 700 mg daily ashwagandha (Withania Somnifera) in healthy college students on sleep, stress and food cravings to healthy college students taking placebo.
- Detailed Description
College aged students tend to report significant daily stress but there is no research on herbal interventions to ameliorate this condition in this population.
This study is a mixed methods, randomized, double blinded, placebo controlled 30 day trial targeting a college aged population. Participants are randomly allocated to either an intervention group (ashwagandha) or a placebo group. Each participant is given a bottle of capsules (capsules look identical but are filled either with a full spectrum dried extract ashwagandha herb or a placebo filled with glycerin). Directions included consuming 1 capsule in the morning and one capsule in the evening. Questionnaires were collected prior to the study and at the end of the study, including an assessment of daily affect. A subset of each group volunteered to attend an intervention specific focus group at 30 days completion of the study.

- Primary Outcome Measures
Name Time Method Impact of ashwagandha on Perceived Stress Change of perceived stress at 30 days Stress was assessed using the Perceived Stress Scale a 10-item validated questionnaire measuring the degree to which situations in participant's life were viewed as stressful. Questions addressed anxious thoughts, locus of control, and coping mechanisms. Scores range from 0-40 (higher scores indicate higher stress levels).

Scores range between 15 and 90 (higher scores indicate more frequent and intense food cravings).
Impact of ashwagandha on Sleep Change of restorative sleep quality at 30 days Restorative Sleep Questionnaire is a 9-item validated scale assessing feelings and experiences about the participant's sleep and their perception of daytime consequences associated with their sleep patterns. Scores range from 0-100 where higher scores indicate better quality sleep.
