Ashwagandha (Withania somnifera) is classified as an adaptogen—an herbal compound that helps the body respond to physical and mental stress.
It's been used for centuries in Indian medicine to improve energy, reduce anxiety, support sleep, and promote overall wellness. Modern clinical studies have shown that ashwagandha root extract may help lower cortisol levels, reduce perceived stress, and improve sleep quality when taken regularly.
How Ashwagandha Capsules Work for Stress
Cortisol reduction: Ashwagandha helps reduce cortisol, the stress hormone that can interfere with sleep, mood, and energy levels.
Anxiety support: Some users report fewer anxious thoughts and a greater sense of calm.
Fatigue improvement: By stabilizing energy and supporting adrenal function, it may reduce mental burnout.
Sleep aid: Especially when taken at night, ashwagandha may promote deeper, more restful sleep.
