KSM‑66® is made exclusively from the root of the ashwagandha plant (not the leaves or stems), in accordance with traditional Ayurvedic use. It is designed to preserve the plant’s natural balance of active compounds.
KSM‑66® is one of the most clinically studied ashwagandha extracts, with multiple randomized, double‑blind, placebo‑controlled human clinical trials published in peer‑reviewed scientific journals.
