Identity and product form

Ashwagandha refers to Withania somnifera. KSM-66 is a branded extract, so evidence for other root, leaf, or mixed extracts should not automatically be transferred to it.

What the reviewed evidence can and cannot show

NCCIH says some ashwagandha preparations may help insomnia and stress, while evidence for anxiety is unclear and many studies are small or use varied preparations. It does not support a broad claim across health conditions.

Sources: National Center for Complementary and Integrative Health

Safety and limits

NCCIH reports possible drowsiness and gastrointestinal effects, rare liver-injury cases, and medicine-interaction concerns. It advises against use in pregnancy or breastfeeding and flags thyroid, autoimmune and surgery considerations.
