How can I find a provider near me that uses amino acid therapy?

We get requests everyday from people looking for a practitioner in their area that uses amino acid therapy. The best place to start is to contact NeuroResearch at and ask them if there is anyone near you that has taken a training with Marty Hinz, MD in your area; they have the most complete list of providers in the country and should be able to find someone you can contact.

The Real Power of 5-HTP and L-Dopa

Amino acid therapy involves the determination and administration of the amino acids and cofactors needed to optimize neurotransmitter function. In the vast majority of cases, this involves trying to optimize the function of the “centrally acting monoamines” which include serotonin, dopamine, norepinephrine and epinephrine. The centrally acting monoamines are synthesized from nutrients, including L-tryptophan, 5-HTP, L-tyrosine and L-dopa. These centrally acting monoamines form a system in which serotonin and the catecholamines (which include dopamine, norepinephrine and epinephrine) oppose one another; in  other words, optimizing the function of the centrally acting monoamines involves more than just giving ‘more’ of one precursor or the other; it also involves getting the balance right between them.

Proper DBS Test Preparation

We have now seen over one hundred clients that had previously been working with other providers for guidance using amino acid therapy. Many of these clients had previous DBS testing completed to help them determine how to optimize their neurotransmitter function. Unfortunately, they did not follow the correct preparation procedure to complete the test and got erroneous results, which then led to erroneous recommendations from their health care providers and sub-optimal resolution of their symptoms.

Dopamine Dominance – The Purpose of the Pill Stop

Once it has been determined that a person is dopamine dominant (via the successful completion of a dopamine challenge), the next step in optimizing neurotransmitter function is determining the amount of L-dopa needed (from standardized mucuna pruriens) to maximize symptom control. In order to do that, periodic adjustments are made to the mucuna dosing followed by a pill stop. Successfully completing a pill stop can provide valuable information on how to proceed; unfortunately, many people do pill stops incorrectly, which delays the optimization of their neurotransmitter function and symptom relief.

What To Do When the Amino Acids Quit Working

Every so often we encounter a case where we have seemingly found a person’s optimized dose of amino acids – meaning that whatever symptoms they were experiencing (i.e., depression, anxiety, urges to pull, migraines, tremor, inability to sleep, etc.) have been significantly reduced and/or eliminated – when ‘out of the blue’ their original symptoms return. This can present itself at anytime, but is most typical after a few weeks or months (3-4 months is most common) on the amino acids at the optimized dose. Before the client or provider begins to change anything (or panic) there are a couple of things that MUST be done to insure accurate and optimal results. (more…)

The Hybrid – High Need for Dopamine and Serotonin Support

There are a lot of disorders related to neurotransmitter dysfunction, including depression, anxiety, insomnia, migraines, trichotillomania, OCD, RLS and Parkinson’s disease, among others. The vast majority of people with these conditions (aside from RLS and Parkinson’s) are serotonin dominant, which means that these people normally require much more support for serotonin than the catecholamines (dopamine, norepinephrine and epinephrine) in order to optimize neurotransmitter function. On the opposite end of the spectrum are those people that are dopamine dominant; this includes people with RLS and Parkinson’s Disease. In addition, there is a small group of people with conditions that are typically serotonin dominant (roughly between 6-12%) that actually end up needing significant dopamine support (i.e, they are dopamine dominant). The only way to determine this is via specialized urine testing. To make matters more complicated, it turns out that there is a third group of people that need significant support for both the serotonin and catecholamine systems; these people are typically labeled “hybrids”.
