Ashwagandha Supplements UK — What the Evidence Says

Clinical dose range studied300–600mg per day

What the research examines

Ashwagandha root extract is among the most clinically studied adaptogens, with randomised controlled trials examining cortisol levels, self-reported stress, anxiety, and sleep quality. KSM-66 and Sensoril are the most studied branded extracts.

Common uses & what to look for

Ashwagandha (Withania somnifera) is commonly included in supplements targeting stress & anxiety. When evaluating products, look for brands that publicly disclose their extract concentration, source type (fruiting body vs. mycelium), and beta-glucan content — these details are the markers Cogniscore uses to assign disclosure scores.

Clinical studies have primarily used doses of 300–600mg per day. Products listing a proprietary blend without disclosing individual ingredient amounts cannot be meaningfully compared against these trial doses.
