Cognition: Studies have directly connected gotu kola consumption to increased cognitive abilities. The main explanation for this is the positive impact gotu kola extract can have on the circulatory system, thereby oxygenating more of the brain and allowing cognition to improve. The antioxidant effects of gotu kola are also somewhat responsible, as they can stimulate neural pathways by eliminating plaque and free radicals in the brain. This has also made it a popular supplement for aging populations, as there is some evidence to suggest that it can slow down the effects of Alzheimer’s disease and dementia.
