This study is designed to evaluate the effects of KSM-66 Ashwagandha root extract (300 mg daily) on weight management and stress reduction in overweight and obese adults. Ashwagandha (Withania somnifera) is a traditional herbal supplement that may help reduce stress and support overall health. In this randomized, double-blind, placebo-controlled trial, participants will receive either Ashwagandha extract or a placebo for the study duration. The main goal is to measure changes in body weight and stress levels. Other health outcomes, such as body mass index (BMI), waist circumference, and quality of life, will also be assessed. The study will help determine whether Ashwagandha is effective and safe for managing stress and supporting weight loss in adults with overweight or obesity.

This randomized, double-blind, placebo-controlled clinical study is being conducted to investigate the potential efficacy and safety of KSM-66 Ashwagandha® root extract (300 mg per capsule) in promoting weight management and reducing stress in adults classified as overweight or obese.

Participants will be randomly assigned to receive either KSM-66 Ashwagandha® capsules or matching placebo capsules for the study duration. Each participant will undergo baseline and follow-up assessments that include anthropometric measurements (body weight, BMI, and waist circumference), psychological evaluations (Perceived Stress Scale and related questionnaires), and laboratory investigations relevant to metabolic and stress-related health.

The study hypothesis is that daily supplementation with KSM-66 Ashwagandha® will lead to a statistically significant reduction in stress levels and body weight compared to placebo. The trial outcomes are expected to contribute to the growing body of evidence supporting the role of Ashwagandha as a safe and natural adaptogenic supplement for weight and stress management in adults.
