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.
