Clinical research indicates that supplement quality significantly impacts effectiveness. Look for these key factors:
- KSM-66 or Sensoril standardized extracts, which have extensive research backing
- Root extract concentration (typically 2.5-5% withanolides)
- Third-party testing certification
- Organic certification when possible
- Full ingredient transparency
Choose supplements that clearly state the withanolide content and avoid products with unnecessary fillers or additives. Root-only extracts are traditionally preferred over leaf extracts. Look for brands that provide certificates of analysis and maintain good manufacturing practices (GMP) certification.
