A neurotransmitter is a chemical messenger that regulates physical processes. Neurotransmitters are responsible for movement, pain, stress, emotions, cognition, energy, cravings, and more. Neurotransmitters imbalances are not only found in the brain but they are excreted outside of the Central Nervous System as well. Neurotransmitters play a role in influencing our digestion, nutrient absorption and impact our musculoskeletal system. When neurotransmitters are off-balance, individuals experience headaches, mood swings, anxiety, fatigue, pain, and depression. Using diagnostic lab technology, we have the ability to test our patients for neurotransmitter deficiencies.
