Nootropics work by influencing the levels of various neurotransmitters, enzymes, and hormones in the brain. Neurotransmitters are chemicals that transmit signals between neurons, and they play a crucial role in cognitive function, mood regulation, and behavior.
Some nootropics work by increasing the levels of neurotransmitters such as acetylcholine, dopamine, and serotonin, which are associated with learning, memory, and mood. Others work by improving blood flow and oxygen supply to the brain, enhancing energy metabolism and cellular function, and reducing inflammation and oxidative stress.
The precise mechanisms of action for different nootropics can vary widely, and some may work through multiple pathways. Overall, the goal of nootropics is to enhance cognitive performance, memory, focus, and mood, while reducing fatigue, stress, and anxiety.
