Aniracetam
Fat-soluble racetam with anxiolytic properties. Enhances creativity, verbal fluency, and reduces anxiety.
Ashwagandha
Ashwagandha is a traditional Ayurvedic herb standardized for withanolides, with evidence supporting modest benefits for stress reduction, anxiety, and cortisol modulation. Multiple clinical trials demonstrate efficacy for stress-related symptoms, though effect sizes are generally moderate.
