What the Science Says
Ashwagandha KSM-66 is a standardized root extract of Withania somnifera, an ancient Ayurvedic herb. It is widely used as an adaptogen — a substance believed to help the body manage stress — and is commonly taken to support cortisol balance, sleep quality, and physical endurance. Typical doses in general use range from 300–600 mg daily, with effects often reported after 4–8 weeks of consistent use, though no study data was provided to confirm these figures here.
What It Doesn't Do
Not a replacement for medical treatment of anxiety or depression. Won't produce overnight results. No evidence from provided studies that it builds muscle on its own. 'KSM-66' branding doesn't automatically mean it's more effective than other extracts — that claim needs independent verification. Not proven to boost testosterone to clinically meaningful levels based on data provided here.
