Buy Modalert, which contains the active ingredient modafinil, may promote neurogenesis—the process by which new neurons are produced in the brain—but there is little empirical evidence to support this claim. Modafinil may stimulate neurogenesis in specific brain regions, according to some animal studies, although the evidence is preliminary and needs more research. Furthermore, there is a dearth of information about modafinil's impact on human neurogenesis. The main way that modafinil increases wakefulness and enhances cognitive function is via altering neurotransmitters including histamine, norepinephrine, and dopamine in the brain. To fully understand modafinil's possible effects on human neurogenesis and how these can affect brain health and cognitive function, more research is required.
