What the Evidence Says

AI-generated · Qwen 3.6 · methodology

This profile includes KSM-66 and L-Theanine, which have strong evidence for supporting stress management and cognitive focus. Phosphatidylserine and pomegranate extract provide moderate support for brain health and antioxidant activity. The inclusion of white button mushroom extract has more limited clinical evidence for specific performance outcomes.
