The Claim

Ashwagandha root extract at 600 mg/day for 8 weeks is associated with a numerically lower incidence of adverse events (5.6%) compared to placebo (9.2%) in adults with stress and anxiety, but this difference is not statistically significant, indicating a safety profile comparable to placebo.

Description
1 study reviewed
In plain English

Taking 600 mg of Ashwagandha root extract daily for 8 weeks did not cause significantly more side effects than a placebo in adults with stress and anxiety. The rate of side effects was actually slightly lower with Ashwagandha (5.6%) than placebo (9.2%), but this difference was not large enough to be considered meaningful.

See the scientific wording

Ashwagandha root extract (ARE) at 600 mg/day for 8 weeks is associated with a numerically lower incidence of adverse events (5.6%) compared to placebo (9.2%) in adults with stress and anxiety, though this difference is not statistically significant, indicating a safety profile comparable to placebo.

Why this might work

None of the studies examined how Ashwagandha root extract affects the body's processes to cause adverse events. Only the overall rates of side effects were compared, and no biological pathway was identified.

  1. Study: Safety of 8-Week Administration With Ashwagandha (Withania somnifera) Root Extract in Adults With Stress and Anxiety: Findings From a Prospective, Randomized, Multi-Center, Double-Blinded, Placebo-Controlled Study.

    The study directly shows that people taking Ashwagandha had about 5.6% side effects compared to 9.2% on placebo, but the difference could be due to chance, so Ashwagandha is about as safe as a sugar pill.
