Moreover, evidence suggests that PQQ may have a profound impact on cognitive function. Studies have shown that supplementation with PQQ can enhance memory, learning, and overall cognitive performance. The benefits are thought to stem from PQQ's ability to stimulate the production of nerve growth factor (NGF), a protein that supports the growth, maintenance, and survival of neurons. This action promotes neurogenesis, the process of forming new neurons, thus creating the potential for regeneration and improved mental agility.
