The human mind is orchestrated by large networks of neurons. Like any type of network, proper function depends on the coordinated efficiency and accuracy of communication. In the brain, a language of chemical messengers allows high-fidelity neuronal conversations that enable us to think, learn, remember, and experience emotion. Known as neurotransmitters, these compounds are critical for emotional wellness, cognitive performance and behavioral health.
Dopamine and serotonin are neurotransmitters that are critical for overall mental health. Dopamine plays important roles in maintaining alertness, while serotonin facilitates relaxation and appetite regulation. A healthy presence of both compounds is contingent upon an adequate supply of nutrients that serve as precursors and cofactors.1,2 Once synthesized, these neurotransmitters must remain intact to function properly. There are many steps in each pathway that provide multiple opportunities for nutritional support. Specifically, three approaches have been characterized:
  1. Provision of amino acids as building blocks for neurotransmitters1*
  2. Adequacy of vitamin and mineral cofactors required by biosynthetic pathways2*
  3. Supplementation of phytonutrients that stabilize neurotransmitters and maintain healthy reuptake to maximize activity in the synapse3*

Dopamine
Dopamine synthesis begins with the amino acid L-phenylalanine, which is sequentially converted to tyrosine and L-DOPA, its immediate precursor.1,2 This pathway requires activated folate (5-methyltetrahydrofolate; MTHF), activated vitamin B6 (pyridoxal 5'-phosphate; P5P) and zinc.2 Once synthesized and released into the synapse, dopamine binds to receptors on the receiving (postsynaptic) neuron to exert its beneficial effects. However, dopamine is subject to removal from the synapse in a process known as reuptake. In addition, dopamine may be degraded by the enzymes catechol O-methyltransferase (COMT) and monoamine oxidase (MAO) (Figure 1). Nearly a decade of research has indicated that the polyphenols in green tea directly target COMT, supporting dopamine stability.4 Rhodiola rosea and grape seed proanthocyanidins have been reported to promote healthy MAO activity.5,6*
Serotonin
Serotonin synthesis begins with the amino acid L-tryptophan, which is hydroxylated to form 5-hydroxytryptophan in a pathway that requires 5-MTHF, vitamin B6 and vitamin C.1,2 Clinical studies have also indicated essential roles of zinc and magnesium.2 Once released into the synapse, serotonin activity depends on healthy reuptake balance, which may be maintained in the presence of taurine.7 Upon binding of serotonin to its receptor, an inositol-dependent signaling pathway ensures effective communication with the postsynaptic neuron (Figure 1).*
The Integrative Mental Health Series is comprised of three products formulated to support overall mental and emotional health. DopaPlus delivers the precursors, cofactors and phytonutrients that support multiple steps in dopamine signaling to promote alertness, cognitive function and positive mood. SeroPlus provides precursors, cofactors and taurine and inositol to help moderate occasional stress, promote relaxation and support healthy eating behavior.*

In many clinical contexts, support for both serotonin and dopamine signaling is indicated. NeuroPure combines serotonin and dopamine precursors and cofactors. This formula provides the polyphenols curcumin and quercetin for healthy MAO activity, which further supports both pathways.8,9 An additional mechanism of these polyphenols is maintaining L-tryptophan availability by moderating the enzyme responsible for its degradation into excitatory metabolites.10 NeuroPure provides comprehensive support for emotional balance and mood stability.*
Each product is designed to be used individually with the co-support of magnesium and essential fatty acids. The Integrative Mental Health Series has been developed based on decades of research and clinical experience in integrative psychiatry. Each formula delivers powerful bioactives in combinations that address multiple aspects of neurotransmission to optimally support mental health and emotional well-being.*
