Neurotransmitters are chemicals that are found in the brain. The function of these chemicals affects our mood, emotions, pain, and energy levels. These chemicals include GABA, serotonin, dopamine, epinephrine, and norepinephrine. If you are suffering from depression, anxiety, fatigue, brain fog, ADD, or chronic pain, your doctor may recommend checking your neurotransmitters to find the underlying cause. This is done with a simple urine test at home. Your physician may be able to help bring these brain chemicals back into balance with diets, supplements, and lifestyle changes. With these non-prescription therapies, you will not suffer the negative side-effects that can often accompany prescribed medication.
