Overview
Ashwagandha is one of the most well-researched adaptogens, with strong evidence supporting its ability to reduce stress and anxiety. It works by modulating the hypothalamic-pituitary-adrenal (HPA) axis, helping the body manage chronic stress more effectively. Its benefits are cumulative and become more noticeable with consistent use over time.
