Description

Reclaim Your Calm. Sharpen Your Focus. Perform at Your Best.

Nutricost KSM-66 Ashwagandha Root Extract delivers one of the most clinically studied forms of ashwagandha available — standardized to 5% withanolides for consistent, reliable potency in every single capsule. Combined with BioPerine® black pepper extract, absorption is optimized so your body actually uses what you take.

Whether you're dealing with the daily grind, pushing hard in the gym, or simply struggling to wind down at night, this full-spectrum root extract works with your body's natural systems to restore balance. KSM-66 is backed by over 20 clinical studies demonstrating real-world results in stress reduction, cortisol management, energy, and cognitive performance.

Each bottle contains 60 vegetarian capsules — a full 30-day supply at the 600mg per-day dose used in clinical research. No fillers, no artificial additives, and manufactured in a cGMP-certified facility for quality you can trust.

At this price point, it's one of the best-value premium ashwagandha supplements on the market. Don't settle for inferior extracts or untested dosages.
