Specific Nutrients That Increase & Decrease Neurotransmitter Activity

Recently I’ve seen a number of people with persistent high anxiety, restlessness, intrusive thoughts or delusions, insomnia, and pacing without improvement despite being on multiple psychiatric medications from their prescribing psychiatrist.

In such cases, it’s important to consider all the tools in the toolbox that might help calm things down while still moving forward with evaluating for underlying causes. Nutrients can be very powerful tools.

In this newsletter, after briefly reviewing the common neurotransmitters, I’ll address:

  • How nutrients increase or decrease neurotransmitters

  • How nutrients increase or decrease activity at receptors that neurotransmitters bind to

  • A specific example where targeted nutrients were used effectively to bring fairly rapid stabilization when medications were unable to. (I’m not opposed to meds when needed, nor would I suggest that they be avoided when symptoms are relatively severe)

First, let’s do a quick….

Neurotransmitter Review

The job of neurotransmitters is to facilitate communication between nerve cells. Here are the most common ones we think about in psychiatry.

  • Serotonin - joy, enjoyment, pleasure, interest, restful sleep 

    • Low activity -  depressed or anxious mood, lack of enjoyment, difficulty falling and staying asleep

  • Dopamine - pleasure and reward  

    • Low activity  - lack of motivation, difficulty starting and finishing tasks, low-stress tolerance, social isolation, helplessness and hopelessness 

    • High activity - worry, insomnia, brain fog, paranoia, mania, psychosis

  • Norepinephrine - arousal

    • Low activity - can contribute to depression

    • High activity - can contribute to nervousness and insomnia

  • GABA - the major inhibitory neurotransmitter involved in calming and rest

    • Low activity -  anxiety, high inner tension, and feelings of overwhelm

  • Glutamate - the major excitatory neurotransmitter in the brain, involved in learning, memory, and mood regulation. Excessive glutamate can cause over-excitation and cell death.

4 Ways Nutrients Impact Neurotransmitters:


1) Nutrients That Help Make Neurotransmitters

  • Vitamin B6 is needed to make serotonin, dopamine and GABA, which is why it is so commonly used in nutrient protocols that address brain symptoms.  

                                              L-Amino Acid Decarboxylase
    5-Hydroxytyrptophan --------------------------------------> SEROTONIN
                                                                B6

                                    L-Amino Acid Decarboxylase
    L-DOPA -----------------------------------------------------> DOPAMINE
                                                               B6

                                         L-Amino Acid Decarboxylase
    GLUTAMIC ACID ---------------------------------------------> GABA
                                                                B6

  • Copper is needed to turn dopamine into norepinephrine. With copper overload (a fairly common root cause of ADHD), there is low dopamine activity [think inattention], and increased norepinephrine [think hyperactivity and/or high anxiety].

                                          Dopamine Beta-Hydroxylase
    DOPAMINE ---------------------------------------------> NOREPINEPHRINE
                                            Copper, Vitamin C, O2
