A non-invasive urine sample can be used to evaluate your key neurohormones including the calming neurohormones Serotonin and GABA as well as the excitatory neurohormones Epinephrine, Norepinephrine and Dopamine. These five key neurohormones maintain the body’s balance of mood and focus. Chronic stress can deplete Serotonin and GABA, the calming neurohormones and raise your excitatory neurohormones leading to anxiety, high blood pressure, ulcers, depression and more.
