You're getting 900mg of **Ashwagandha** root per serving — a generous dose by weight, but this is whole root powder, not a standardized extract. The clinical trials behind ashwagandha's stress and cortisol benefits used concentrated extracts standardized to withanolides, typically at 300–600mg. Raw root powder contains far less of the active compounds, so 900mg of powder isn't equivalent to 900mg of extract.

Ashwagandha has moderate clinical evidence for reducing perceived stress and supporting sleep quality, which aligns with this product's strongest use cases. At the two-capsule serving, you're getting a traditional-level dose that may offer some adaptogenic support — but your results will likely depend on how your body responds to the unstandardized form.

The main gap is the lack of extract standardization. If you're specifically looking for the cortisol-lowering and anxiety-reducing effects studied in clinical trials, a product using a standardized extract would give you more predictable withanolide content per dose.
