Dr. Hillis has been studying amino acid loading methods for repletion of neurotransmitters for over 20 years. Major breakthroughs in the scientific community occurred in 2002 that greatly increased the ability of the clinician to use urinary neurotransmitter testing to obtain more predictable and efficacious results in manipulating neurotransmitter levels. Dr. Hillis has been actively involved in neurotransmitter evaluations and natural therapies to effectively improve neurotransmitter balance. Dr. Hillis has given numerous presentations on neurotransmitter therapy to both public audiences and to his colleagues.This testing is available for his patients and is part of many of the comprehensive workups with patients who present with complex issues that have not been helped elsewhere.

Some of the common symptoms of neurotransmitter inbalance include:

  • Feelings of sadness
  • Feelings of anxiousness
  • Poor sleep
  • Fatigue
  • Behavioral problems
  • Foggy thinking
  • Headaches

Typically the urinary neurotransmitter profiles ordered by Dr. Hillis will include measurement of:

  • serotonin
  • epinephrine (adrenalin)
  • norepinephrine
  • dopamine
  • GABA
  • and others as needed on an individual basis.
