Although it is widely believed that a serotonin deficiency plays a role in depression, there is no way to measure its levels in the living brain.
Q. What should your serotonin level be?
Generally, the normal range for serotonin levels in your blood is 101–283 nanograms per milliliter (ng/mL). This benchmark, however, may differ slightly depending on the measurements and samples tested, so talk to your doctor about specific test results. High levels of serotonin may be a sign of carcinoid syndrome.

Q. How does serotonin affect brain development?
The neurotransmitter serotonin (5-HT) plays a central role in brain development, regulation of mood, stress reactivity and risk of psychiatric disorders, and thus alterations in 5-HT signaling early in life have critical implications for behavior and mental health across the life span.
Q. What can too much serotonin in the brain during infancy cause?
Perhaps excessive serotonin during this period falsely signals a sufficiency of serotonergic growth leading to stunted development. In fact, maternal inflammation was recently found to lead to increased levels of 5-HT in the fetal brain which subsequently inhibits serotonergic development (Goeden et al., 2016).
Q. What is the antidote for serotonin syndrome?
Cyproheptadine, a serotonin 2A antagonist, is usually recommended and is the most widely used antidote.
Q. How do doctors treat serotonin syndrome?
Treatment may include: Benzodiazepine medicines, such as diazepam (Valium) or lorazepam (Ativan) to decrease agitation, seizure-like movements, and muscle stiffness. Cyproheptadine (Periactin), a drug that blocks serotonin production. Intravenous (through the vein) fluids.
Q. What time of day is serotonin highest?
The results show that in both the tryptophan-treated and untreated groups the highest values appeared during the beginning of the darkness with a peak at 9, 10 and 11 p.m. in controls, and at 9 p.m. in the tryptophan-treated group.
