Frequently Asked Questions

What does ashwagandha do?

Standardized extracts have moderate evidence for reducing perceived stress and cortisol and may modestly help sleep. Strength/testosterone claims are weaker and dose-dependent.

KSM-66 or Sensoril?

Both are standardized and studied. KSM-66 is a root-only extract often used for general stress and performance; Sensoril is higher in withanolides and leans calming. Either beats generic root.
