Does taking melatonin reduce dopamine?
Dopamine (DA) content of the posterior pituitary was decreased progressively by melatonin administration, with a reduction of greater than 50% after 5 weeks of treatment.
Melatonin modulates dopamine production and pathways in areas of your brain involved in movement disorders such as Parkinson's Disease and tardive dyskinesia. Melatonin also interacts with dopamine's role to your body's biological clock.
A number of factors may be responsible for reduced dopamine in the body. These include sleep deprivation, obesity, drug abuse, saturated fat, and stress.
Melatonin may have an antidepressant effect by increasing the expression of GABAA receptors in the rat brain. Melatonin also increases neuroplasticity in the hippocampus, which plays an important role in the development of depression.
Along with eating a balanced diet, many possible supplements may help boost dopamine levels, including probiotics, fish oil, vitamin D, magnesium, ginkgo and ginseng. This, in turn, could help improve brain function and mental health.

Your body needs serotonin from your pineal gland to produce melatonin. Both dopamine and serotonin are involved in your sleep-wake cycle. Dopamine can inhibit norepinephrine, causing you to feel more alert. Serotonin is involved in wakefulness, sleep onset, and preventing REM sleep.
Having too much dopamine — or too much dopamine concentrated in some parts of the brain and not enough in other parts — is linked to being more competitive, aggressive and having poor impulse control. It can lead to conditions that include ADHD, binge eating, addiction and gambling.
Melatonin at a dosage of 0.5 mg/kg increased medial hypothalamic serotonin levels at 60 and 90 min after the injection. However, the dose of 1 mg/kg increased the levels of this amine or its metabolite in the preoptic area-anterior hypothalamus, medial and posterior hypothalamus, amygdala, and midbrain.
How does melatonin affect people with ADHD?
According to one study, children with ADHD were able to sleep longer and fall asleep faster after taking melatonin daily combined with their ADHD medication over several weeks. Additionally, I have young patients who take melatonin on a daily basis, and I've also worked with kids and teenagers who take it regularly.

In some humans, stress does not, however, cause depression. It is hypothesized that in these individuals, melatonin, which is normally a product of serotonin, may be converted back to its precursor and thus replenish serotonin stores.
