Neurotransmitters and Their Purpose

The balance of neurotransmitters affects many processes of the body including hormone regulation, digestion and metabolism. Symptoms of an imbalance can include pain, anxiety, depression, insomnia, menopause, stress, fatigue, weight, addictions and other mood issues.

Normal function in the brain is a matter of the appropriate relay of electrical signals and subsequent chemical (neurotransmitter) release. The electrical signals and release of neurotransmitters (nerve cells) communicate together with the organs in the body. Neurons act as an accelerator, regulate speed and dictate whether or not a neurochemical signal is even produced.

The excitatory neurotransmitter system acts as an accelerator, releases chemicals that in turn regulate the nervous system, which is responsible for sending signals.


The inhibitory neurotransmitter system acts as a brake. When chemicals are released at the inhibitory stage the system then slows down. The inhibitory neurotransmitter system is responsible for preventing the signals from continuing.

There are other transmitters and modulators that factor into the effectiveness of the two systems.

In order to effectively understand how an individuals neurotransmitter system is working there are THIRTEEN DIFFERENT PARAMETERS used for testing.

Aspartic Acid

Low levels have been linked to chronic fatigue syndrome.


Plays a significant role in cognitive function and emotion, as well as roles in the cardiovascular, renal, hormonal and central nervous system.


Raises the concentration of free fatty acids in blood as well as inhibits insulin excretion.


Lack of GABA is associated with increased anxiety and sleep-related problems.


Plays an important role in motor behavior as well as influences the secretion of pituitary hormones.


This is the most prevalent amino acid in the body. It plays in important role in the ph balance, immune function, mental acuity and carbohydrate cravings.


Regulates neuro-transmission, primarily in the brain stem and spinal cord.


Is relevant in the control of sleep and wakefulness and influences the secretion of hormones for the pituitary.


Important for focus and attention.

Phenylethylamine (PEA)

Increases mental acuity and elevates mood and is involved in depression, ADD/ADHD, schizophrenia and psychopathic conditions.


Has been extensively studied and is a therapeutic target for conditions like depression, compulsive disorders, anxiety, insomnia and migraines.


One of the most prevalent amino acids in the brain.


Accounts for an individual’s level of hydration, which significantly affects urinary results.
