About this product
Jarrow Formulas Ashwagandha uses KSM-66, the most clinically studied ashwagandha extract in the world, with over 20 published randomized controlled trials demonstrating effects on stress, cortisol, sleep, and exercise recovery. KSM-66 is made exclusively from ashwagandha roots (no leaf, which contains different bioactives) using a green-chemistry process that requires no chemical solvents. The 5% withanolide standardization ensures consistent dosing batch to batch. Take 1-2 capsules daily for 600 mg, the dose used in most clinical research. Effects typically emerge within 2-4 weeks. Best taken with a meal to maximize absorption.
