The Claim

Daily supplementation with 150 mg of Ashwagandha root extract sustained-release (AshwaSR) for 60 days significantly reduces perceived stress by 38.6%, improves sleep quality by reducing PSQI scores by 41.3%, and enhances psychological well-being by increasing OHQ-8 scores by 19.2% in healthy adults with moderate stress, while not producing a statistically significant reduction in cortisol levels.

In plain English

Taking 150 mg of Ashwagandha root extract daily for 60 days reduces perceived stress by 38.6%, improves sleep quality by 41.3% as measured by PSQI, and increases psychological well-being by 19.2% as measured by OHQ-8 in healthy adults with moderate stress, without significantly lowering cortisol levels.

See the scientific wording

A 60-day daily supplementation with 150 mg of Ashwagandha root extract sustained-release (AshwaSR) significantly reduces perceived stress by 38.6%, improves sleep quality (PSQI score reduction of 41.3%), and enhances psychological well-being (OHQ-8 score increase of 19.2%) in healthy adults with moderate stress, though cortisol reduction is not statistically significant.

Why this might work

Active compounds in Ashwagandha enter the brain and calm overactive immune cells, reducing inflammation that disrupts sleep and amplifies stress signals. This also quiets the brain's stress control center, lowering the body's stress hormone output and helping the mind feel calmer and more resilient.

    Taking 150 mg of this Ashwagandha supplement daily for two months helped people feel less stressed, sleep better, and feel happier — just like the claim says. But it didn’t lower their stress hormone levels, which also matches what the claim says.
