If you're looking for stress relief and lower cortisol, **Ashwagandha** has multiple RCTs supporting those benefits, and this product combines three forms of the herb — root powder (380mg), root extract (280mg), and a CO2 extract (10mg) — totaling 670mg per caplet. What this means for you: that total sits above the 300–600mg range studied in most clinical trials using standardized extracts like KSM-66 or Sensoril.

The withanolide content is where it gets nuanced for you. The label shows about 2.16mg total withanolides across all three sources. KSM-66 standardizes to 5% withanolides, delivering roughly 15mg per 300mg dose. Himalaya's withanolide concentration is significantly lower, meaning you're getting a full-spectrum whole-herb approach rather than a concentrated extract. Whether that matters depends on whether withanolide concentration or whole-plant synergy drives outcomes — the research is mixed.

If you want a standardized, research-matched ashwagandha dose, a KSM-66 or Sensoril extract would more closely mirror what was used in clinical trials. This product takes a traditional whole-herb approach, which may appeal to you but is harder to compare to published study protocols.
