How Do Nootropics for Intelligence Work?

Nootropics are composed of natural substances that enhance cognitive function, including memory, creativity, and intelligence. Most nootropics work by increasing cerebral blood flow, which improves oxygen and nutrient delivery to the brain. This results in an increased production of neurotransmitters, which help improve attention, focus, and memory.(7)

Nootropics also increase the growth of new neurons in the brain, which leads to enhanced brain plasticity and cognitive flexibility. Lastly, they also help to reduce stress and anxiety, which negatively impact cognitive function.

Although the research on nootropics is ongoing, many people find them useful for improving their mental performance, memory, and concentration.
