Now Foods KSM-66 Ashwagandha is a 90-capsule bottle of a root-only ashwagandha extract, the form most clinical studies on stress and sleep used. KSM-66 is a branded, standardized extract, so the dose per capsule is consistent from bottle to bottle, and the capsules are vegan and gluten free. It suits people who want a plain, single-ingredient adaptogen for everyday stress or sleep support rather than a blend. Rivals often combine ashwagandha with L-theanine, magnesium or melatonin, or use cheaper root powder; this one keeps it simple and study-backed.
