Does caffeine increase dopamine?
Sources:
Yes, caffeine does increase dopamine levels, though the increase is relatively modest compared to other substances like nicotine or cocaine. However, regular ingestion of caffeine can increase the upregulation of certain dopamine receptors, enhancing the overall experience of dopamine's effects. This interaction not only raises dopamine levels but also increases the density of the receptors, which allows for a greater impact of dopamine on the brain 1.
Furthermore, research indicates that caffeine can increase dopamine release in the brain by about 30%, and it also has a protective effect on dopamine neurons 2.
