At 450mg per capsule, you're already within the clinical dose range studied for stress and cortisol reduction. Follow the label's recommendation of 2-3 capsules daily and you'll be at 900-1,350mg — well above the minimum effective dose. **Ashwagandha** has solid clinical backing for lowering perceived stress and supporting sleep quality, and this product gives you enough to work with.
The extract is standardized to 2.5% withanolides (11mg per capsule), which confirms you're getting the active compounds responsible for ashwagandha's effects. However, this isn't a branded extract like KSM-66 or Sensoril, which have their own clinical trials using specific extraction methods. You're getting a generic standardized extract — it should still deliver, but the research trail is less direct.
One thing to watch: the label suggests up to 3 capsules daily, which puts you at 1,350mg. That's generous, and most clinical trials cap at 600mg for branded extracts. Starting with 1 capsule (450mg) is a reasonable approach to assess your tolerance before scaling up.
