Is Ashwagandha effective for brain fog?

Ashwagandha has been shown to be effective in reducing brain fog by lowering cortisol levels, thus reducing stress and anxiety, which can improve cognitive function and overall well-being. In a study cited by Louisa Nicola, chronically stressed adults who supplemented with Ashwagandha experienced significantly greater reductions in cortisol compared to a control group, with those taking higher doses seeing about a 30% reduction in stress on average. This reduction in cortisol can help in making one feel more calm, able to think clearer, and potentially eliminate brain fog 1.
