What is serotonin. Serotonin is often referred to as the "feel-good" neurotransmitter, Freimuth says. When levels are normal, you're more likely to feel happy and emotionally stable.
“Most studies found no evidence of reduced serotonin activity in people with depression compared to people without, and methods to reduce serotonin availability using tryptophan depletion do not ...
With the sun going down earlier, there is less light for people to intake can could lead to lower serotonin levels. That can disrupt a person's circadian rhythm or "human clock."
Certain SSRI medications have been shown to lower serotonin levels below the baseline after chronic use, despite initial increases. [100] The 5-HTTLPR gene codes for the number of serotonin transporters in the brain, with more serotonin transporters causing decreased duration and magnitude of serotonergic signaling. [ 101 ]
Selective serotonin reuptake inhibitors (SSRIs) selectively inhibit the reuptake of serotonin and are a widely used group of antidepressants. [31] With increased receptor selectivity compared to TCAs, undesired effects such as poor tolerability are avoided. [29] Serotonin is synthesized from an amino acid called L-tryptophan.
Escitalopram, a selective serotonin reuptake inhibitor (SSRI) used as an antidepressant.. Reuptake inhibitors (RIs) are a type of reuptake modulators.It is a drug that inhibits the plasmalemmal transporter-mediated reuptake of a neurotransmitter from the synapse into the pre-synaptic neuron.
Relative to serotonin–norepinephrine–dopamine reuptake inhibitors (SNDRIs), which also inhibit the reuptake of norepinephrine in addition to serotonin and dopamine, SDRIs might be expected to have a reduced incidence of certain side effects, namely insomnia, appetite loss, anxiety, and heart rate and blood pressure changes.

As if the world required any more misunderstanding around mental health, a new study showing depression isn’t caused by low levels of serotonin is, indeed, contributing to it. “News” to ...
