The Claim

Daily administration of 300 mg of Ashwagandha root extract sustained-release (AshwaSR) for 60 days results in faster and greater improvements in perceived stress, psychological well-being, and eating behavior compared to 150 mg of the same extract over the same period.

Cause and effect
1 study reviewed
In plain English

Taking 300 mg of Ashwagandha root extract daily for 60 days leads to greater and quicker reductions in stress and improvements in mood and eating habits than taking 150 mg daily for the same time.

See the scientific wording

Ashwagandha root extract sustained-release (AshwaSR) at 300 mg daily produces faster and greater improvements in perceived stress, psychological well-being, and eating behavior than the 150 mg dose over 60 days, suggesting a dose-dependent effect on the speed and magnitude of benefit.

Why this might work

Higher doses of Ashwagandha extract more strongly block the brain's stress signal system and calm inflammation in the brain, which lowers the body's stress hormone, improves sleep, and makes people feel less stressed and more emotionally balanced.

  1. Study: Efficacy and safety of Ashwagandha root extract sustained-release (AshwaSR) capsules in healthy adult, stressed subjects: A randomized, double-blind, placebo-controlled, parallel-group, 3-arm clinical trial

    People who took a higher dose of Ashwagandha (300 mg) felt less stressed, slept better, and were happier than those who took a lower dose (150 mg), and only the higher dose lowered their stress hormone. This suggests more medicine works better.
