It was previously reported that caffeine has the capability to reduce brain serotonin synthesis by inhibiting tryptophan hydroxylase, the rate-limiting enzyme for central serotonin biosynthesis (Lim et al., 2001), and/or to reduce brain serotonin/dopamine ratio by blocking adenosine α1 and α2 receptors within the CNS.
Does caffeine increase serotonin?
Diet can also influence one’s mental health. Coffee increases your serotonin and dopamine levels … for as long as you take it. Once you stop drinking coffee, you will go into withdrawal. Your brain, used to the high levels of neurotransmitters, will act as if there is a deficiency.

What neurotransmitter is blocked by caffeine?
Caffeine activates noradrenaline neurons and seems to affect the local release of dopamine. Many of the alerting effects of caffeine may be related to the action of the methylxanthine on serotonin neurons. The methylxanthine induces dose-response increases in locomotor activity in animals.
Is caffeine bad for serotonin syndrome?
Consumption of large amounts of caffeine in tandem with the ingestion of serotonergic medications, particularly antidepressants, may contribute to the development of serotonin syndrome in susceptible patients (Reference Shioda, Nisijima and NishidaShioda 2004).
Does sleep boost serotonin?
Accordingly, cortical serotonin levels are high during wakefulness, reduced during slow wave sleep (SWS), and virtually quiescent during rapid eye movement sleep. During sleep deprivation the serotonin release is even higher than during the previous wake period, as animal findings suggest.
Does alcohol lower serotonin?
Drinking alcohol can temporarily boost serotonin levels, therefore making you feel happier, but in the long term, excess alcohol can actually lower serotonin levels, and therefore either causing or exacerbating depression.
What are the signs of too much serotonin?
- Agitation or restlessness.
- Rapid heart rate and high blood pressure.
- Dilated pupils.
- Loss of muscle coordination or twitching muscles.
- Muscle rigidity.
- Heavy sweating.
