The Claim

Daily supplementation with 300 mg of Ashwagandha root extract sustained-release (AshwaSR) for 60 days significantly reduces perceived stress by 41.6%, improves sleep quality by reducing PSQI scores by 51.5%, enhances psychological well-being by increasing OHQ-8 scores by 36.3%, and lowers serum cortisol levels by 19.15% in healthy adults with moderate stress compared to placebo.

In plain English

Taking 300 mg of Ashwagandha root extract daily for 60 days reduces perceived stress by 41.6%, improves sleep quality by 51.5%, increases psychological well-being by 36.3%, and lowers serum cortisol levels by 19.15% in healthy adults with moderate stress compared to a placebo.

See the scientific wording

A 60-day daily supplementation with 300 mg of Ashwagandha root extract sustained-release (AshwaSR) significantly reduces perceived stress by 41.6%, improves sleep quality (PSQI score reduction of 51.5%), enhances psychological well-being (OHQ-8 score increase of 36.3%), and lowers serum cortisol levels by 19.15% in healthy adults with moderate stress, compared to placebo.

Why this might work

Active compounds in Ashwagandha enter the brain and calm overactive stress circuits, which lowers the production of the stress hormone cortisol. This reduces physical stress signals and calms brain inflammation, leading to better sleep, less perceived stress, and improved mood.
