What the evidence actually shows
Several small randomized trials (6–10 weeks, 300–600 mg a day of a standardized root extract) report modest improvements in sleep quality, most clearly in people with insomnia; a 2021 meta-analysis rated the effect small. Trials are short and many were funded by extract makers. Rare cases of liver injury have been reported.
Commonly used: 300–600 mg/day standardized root extract.
How this list is built: these are ashwagandha ksm-66 products ranked by real cost per dose across our whole ashwagandha ksm-66 catalogue — not filtered or re-ordered by sleep. We don’t hold per-product evidence for a specific use, so we don’t pretend to rank for one. Products whose own label says they are for something else are left out.
