“Alcohol also reduces levels of the excitatory neurotransmitter glutamate and may even influence how we perceive and respond to threats. When under the influence of alcohol, there's less activity in the brain's visual and limbic regions.”

“Choline is an essential dietary nutrient that serves as a precursor for methylation, affecting epigenetics globally, and plays a role in the production of the neurotransmitter acetylcholine.”

“Integral to the cold shock response is the release of norepinephrine, a hormone and neurotransmitter produced in the adrenal glands and some brain regions. Norepinephrine increases heart rate, activates thermogenesis (heat production), constricts blood vessels, and modulates immune function.”

“The same mechanism by which coffee makes us less sleepy explains its neuroprotective effects. Caffeine blocks adenosine receptors (namely the adenosine A2A and A1 receptors) thereby increasing neural activity and neurotransmitter release.”

“A new study finds that the gut bacteria Bacteroides produces the neurotransmitter GABA and that people with major depression have fewer Bacteroides gut bacteria compared to healthy individuals.”

“When melatonin binds to receptors in the brain (MT1 and MT2), it synchronizes the body’s internal clock to promote feelings of sleepiness, reduces core body temperature (a signal for sleep onset), decreases the activity of wake-promoting neurons, and enhances the release of inhibitory neurotransmitters (i.e., GABA).”

“Evidence suggests it influences sleep by regulating neurotransmitters in the brain such as gamma aminobutyric acid (GABA) and acetylcholine. Epigallocatechin gallate (EGCG) is found in tea. It exerts potent antioxidant, anti-cancer, and anti-proliferative properties.”

“In addition, both groups demonstrated elevated levels of various neurotransmitters, including serotonin, norepinephrine and others, in brain tissue, along with changes in the expression of key proteins related to neural signaling.”

“Drugs that modulate neurotransmitter (e.g., serotonin, dopamine, acetylcholine) concentrations are a common strategy for treating alcohol misuse and neuropsychiatric disorders; however, many patients don't adequately respond to these drugs.”
