Which supplement is commonly used to improve overall mental clarity?

Ginkgo biloba is often recognized for its potential benefits in enhancing cognitive functions and mental clarity. This herbal supplement is derived from the leaves of the Ginkgo biloba tree and has been studied for its possible effects on blood circulation, particularly in the brain, which can contribute to improved cognitive function. It is commonly used with the aim of increasing mental alertness, memory, and overall cognitive performance, making it a popular choice among individuals seeking to enhance their mental clarity.

Ginseng, while known for its general health benefits and potential to reduce fatigue, is not specifically noted for improving mental clarity in the same way as ginkgo biloba. Green tea does contain compounds that may promote cognitive function and has antioxidant properties, but its primary appeal is often related to overall health and wellness rather than targeted mental clarity. St. John's Wort is primarily used for mood enhancement and treating mild to moderate depression rather than as a cognitive enhancer.
