Abstract Summary
Objective: This study investigates the effects of Ashwagandha (Withania somnifera) on lowering cortisol levels and reducing stress in adults.
Context: Ashwagandha is well-known for its adaptogenic properties, which are believed to help the body cope with stress by modulating cortisol levels. This study aims to determine the effectiveness of Ashwagandha supplementation in reducing cortisol and alleviating stress-related symptoms.
Methods Used
Approach: A randomized, double-blind, placebo-controlled trial was conducted over an 8-week period. The study included 100 participants aged 25-45, all of whom reported experiencing moderate levels of stress. The participants were divided into two groups: one group received 300 mg of Ashwagandha extract twice daily, while the other group received a placebo. Cortisol levels and self-reported stress were measured at the beginning and end of the study.
Data Collection: The primary outcome measures were serum cortisol levels (measured via blood samples) and stress levels (assessed using the Perceived Stress Scale).
Researchers' Summary of Findings
Impact on Health: Participants who received Ashwagandha showed a significant reduction in cortisol levels compared to the placebo group. On average, cortisol levels decreased by 25% in the Ashwagandha group, while the placebo group showed a reduction of only 5%. Self-reported stress scores also decreased significantly in the Ashwagandha group, with participants reporting a 35% reduction in stress levels compared to a 10% reduction in the placebo group.
Health Implications: The results suggest that Ashwagandha supplementation may effectively reduce cortisol levels and alleviate stress in adults. These findings support its use as a natural supplement for stress management.
