To achieve optimal efficacy, minimal side effects, and prevent depletion of other amino acids and neurotransmitters, 5-HTP must be administered in proper balance with dopamine amino acid precursors along with proper levels of sulfur amino acids. Synthesis and metabolism are controlled by transporter function. Transporters move serotonin, dopamine and their amino acid precursors into and out of cells to sites where synthesis and metabolism occur.

MTO is an in situ method for determining the functional status of OCT responsible for establishing serotonin and dopamine levels throughout the body. Optimization requires establishing serotonin in the Phase 3 optimal range while dopamine is in its Phase 3 optimal range. The Phase 3 optimal ranges of serotonin and dopamine are independent of one another.

When both serotonin and dopamine are in their respective phase 3 optimal ranges, optimization has occurred. Optimal group results cannot be obtained without MTO. The following are group effective therapeutic ranges defined by MTO during simultaneous administration of serotonin and dopamine precursors:. The effective therapeutic ranges listed above are independent of each other. For example, in one patient, a daily 5-HTP dosing value of 2, mg per day with an l -dopa dosing value of 30 mg per day may be required for proper balance of transport to place both serotonin and dopamine in their respective Phase 3 optimal ranges.

Another patient may require 25 mg per day of 5-HTP with 2, mg of l -dopa for Phase 3 optimization. Dosing values required for transporter optimization are highly individualized. To understand the extreme variability in the dosing levels of 5-HTP and the other amino acid precursors, it is important to understand why these transporters react so differently from one individual to the next.

Neurotransmitters facilitate the flow of electric signals across the synapse between the pre- and post-synaptic neurons. When a change in the overall flow of electricity across the synapse is needed, a signal is sent throughout the body that encodes the identical transporters to regulate and control neurotransmitter flow in the specific manner required to optimize this flow. This process may damage areas regulating affect and mood, leading to depression.

Since serotonin and dopamine do not cross the blood—brain barrier, the total number of serotonin and dopamine molecules present in the brain is a function of the amount of nutrients amino acid precursors available to be synthesized into new neurotransmitter molecules.

If the amount of neurotransmitter molecules is low or inadequate, a relative nutritional deficiency exists. Optimal efficacy and minimized side effects are not a function of achieving sufficiently high amino acid dosing levels; they are a function of achieving a proper balance between serotonin and dopamine. Intuitively, the potential is extraordinary, but from a practical level efficacy is no better than placebo. In review of the science, effective integration of 5-HTP into a patient management plan is much more complicated than simply giving some 5-HTP in order to have more serotonin throughout the system.

Administration of 5-HTP alone is contraindicated for depression and any process involving a catecholamine component due to its ability to facilitate depletion of these neurotransmitters. Administering serotonin or dopamine amino acid precursors should never involve administration of only one amino acid. Improperly balanced amino acid precursors are associated with decreased efficacy, increased side effects, and depletion of the nondominant system.

Introduction In the United States, the nutritional supplement 5-hydroxytryptophan 5-HTP became available over the counter in April of The argument for using 5-HTP When placed in the proper context, the following basic chemical properties 2 — 15 explain the failure of 5-HTP to achieve consistent results. The following scientific facts are generally accepted without dispute: In central nervous system disease states associated with synaptic serotonin dysfunction, synaptic serotonin levels in the brain must be increased to induce optimal outcomes.

Serotonin does not cross the blood—brain barrier. Short-term efficacy of 5-HTP alone Generally, efficacy studies related to 5-HTP fall into one of two categories: open nonblinded and double-blind, placebo-controlled studies. Monoamine depletion by amino acid precursors Serotonin and dopamine systems exist in two distinctly different and separate states. Open in a separate window. Figure 1. Synthesis pathway of serotonin and catecholamines. Abbreviation: 5-HTP, 5-hydroxytryptophan.

Figure 2. Effects of 5-HTP when administered in an unbalanced manner Amino acid precursors of serotonin and dopamine in the competitive inhibition state are intertwined during synthesis, metabolism, and transport to the point that they function as one system.

Administration of 5-HTP in a properly balanced manner To achieve optimal efficacy, minimal side effects, and prevent depletion of other amino acids and neurotransmitters, 5-HTP must be administered in proper balance with dopamine amino acid precursors along with proper levels of sulfur amino acids.

It is a chemical by-product of L-tryptophan. It is also produced from the seeds of the Griffonia Simplicifolia plant. Serotonin helps to regulate sleep , temperature, appetite, sexual drive, and sensations of pain, among other things, and so it can have a profound effect on sleep and restfulness.

Two of the most intriguing areas in which serotonin has been successfully applied are in the treatment of depression, and in some negative effects of Down syndrome. Some research indicates that oral administration of 5-HTP reduces symptoms of depression. More study needs to be done, but early indications are that it might be as effective as conventional antidepressant therapy in some patients. Some studies also show that giving 5-HTP to infants with Down syndrome can improve muscle activity — though other studies seem to contradict this.

It may be that taking it alongside conventional drugs is the key to its efficacy, improving overall results to improve development, including social and language skills.

It seems that, for most people, it is safe to take 5-HTP orally, though that is not the case for everyone. Some people report experiencing eosinophilia-myalgia syndrome EMS after taking the drug by mouth. Anyone who experiences symptoms of these side effects should seek emergency medical attention. A person should talk with their doctor before taking 5-HTP or any other supplements. Some supplements can worsen underlying medical conditions or interact with medications they are already taking.
