AnxietyJacquie Eubanks RN BSNAnyone who has experienced anxiety is familiar with what can be described as an unpleasant feeling, a vague sense of unease and apprehension. While anxiety disorders affect over 40 million adults in the US, virtually everyone has felt anxious at some point in time. Symptoms such as mild stomach discomfort, perspiration, a quickening of the heartbeat, are common reactions to stressful situations. Similar to fear, anxiety triggers the fight or flight stress response and the release of stress hormones, including adrenaline, to see you through a momentary anxiety producing circumstance.

Normal intermittent anxiety is beneficial in certain temporary situations, a job interview, a college exam, public speaking, or what a performer would call opening night jitters. When anxiety becomes chronic or irrational and begins to interfere with normal everyday life, it can lead to physical illness and a psychological disorder diagnosis. Dissimilar to fear, which is a rational response to a real danger, chronic irrational anxiety generally lacks a clear or realistic cause, yet still produces physical responses that can become debilitating and lead to chronic conditions.

Chronic disproportionate anxiety that negatively affects sleep and concentration or results in avoidance of social situations, is classified as a disorder. While treatable, statistics show that a large percentage of adults who have anxiety disorders never receive treatment, such as therapy or medications. People who have undiagnosed or untreated anxiety disorders are more likely to self-medicate with nicotine, alcohol or street drugs that may temporarily relieve anxiety symptoms, but may also greatly affect general health and wellbeing in the long term. Those who are struggling to manage the symptoms of persistent, but not debilitating, anxiety may have anxious thoughts or behaviors that may be improved by dietary and lifestyle changes.

  • Eating more protein and healthy fats, not skipping meals, and avoiding sugar and refined carbs can keep blood sugar stable and eliminate blood sugar crashes. Low blood sugar can initiate a stress response and the release of stress hormones that feels eerily like anxiety.
  • Gradually decreasing caffeine intake until you can eliminate it entirely can help to improve sleep, stabilize energy and improve the stress response.
  • Getting adequate, restful sleep helps to eliminate the anxiety-insomnia-sleep deprivation cycle, leaving one less vulnerable to anxiety. To help wind down in the evening, dim the lights an hour before bedtime, take a warm shower or bath, or do a short meditation and some gentle stretching to help you relax.
  • Taking probiotics and eating fermented foods can help to promote healthy gut flora and improve gastrointestinal function. Digestive tract health can affect mood and may play a role in anxiety disorders.
  • Take every opportunity to get in some physical activity, as exercise helps to relieve stress and anxiety.

Anyone who struggles with anxiety will tell you that managing anxiety is not an easy task. Good lifestyle habits are certainly beneficial, as proper diet, sufficient exercise, and good quality sleep can noticeably improve the anxiety and stress response. As well, proper supplementation can improve the quality of sleep, provide calming minerals, support mood and neurotransmitter production and aid adrenal function, resulting in anxiety relief, improved focus, increased energy and more optimal stress management.

L-theanine – Found naturally in green tea, this amino acid enhances cognition and focus, while surprisingly promoting relaxation without inducing drowsiness. Utilized to naturally relieve anxiety and stress, L-theanine calms both the body and the mind, bringing about a state of wakeful relaxation. When you need to chill out, L-theanine can help.

Magnesium – Widely known as a calming mineral, magnesium is involved in hundreds of biochemical processes, including energy production, blood glucose regulation and stress management, as well as immune system and adrenal function support. Magnesium deficiency is linked to symptoms of anxiety, depression, mood imbalances, and insomnia, all of which benefit from magnesium repletion.

GABA – Synthesized naturally in the brain and widely distributed throughout the central nervous system, GABA is a major neurotransmitter that has relaxation-inducing and stress-relieving effects. Low levels are GABA are associated with anxiety, depression and insomnia. Clinical studies have shown that GABA supplementation can promote feelings of calmness, increase metal clarity and focus, and support more restful sleep.

Kava – Used traditionally for centuries to enhance relaxation, improve mood and support sleep, kava has been shown to elevate mood, improve stress management, reduce the negative effects of stress, and relieve symptoms associated with generalized anxiety, including persistent worry, restlessness, insomnia, fatigue and muscle tension.

Let’s Talk Neurotransmitters

NeurotransmittersJacquie Eubanks RN BSN



Neurotransmitters are chemical messengers that allow signals to cross synapses to transmit information from a nerve cell or neuron to a target cell. Essentially, a synapse is the junction point between two neurons. As the basic working unit of the brain, neurons are specialized cells within the nervous system that allow the brain to transmit electrically charged messages to other nerve, gland and muscle cells. Because neurotransmitters relay information that causes reactions, such as telling a muscle to contract or a gland to secrete a hormone, anything that affects the behavior of neurotransmitters affects the function of the body. By their effects on neurotransmitter receptor cells, neurotransmitters coordinate behavior by stimulating an action or inhibiting an impulse.

Scientists have identified at least 100 neurotransmitters, and evidence suggests we may have a significantly higher amount. Many neurotransmitters are synthesized from precursors like amino acids. Each one performs specific tasks and plays a major role in everyday life and function. To be identified as a neurotransmitter, a chemical must be synthesized in a neuron, must be released and produce a targeted response and must have a mechanism to remove the chemical from the activation site once it has finished its intended function. Neurotransmitters are commonly described as either inhibitory or excitatory.

Neurotransmitter imbalances are connected to diseases and health conditions, including Parkinson’s, depression, insomnia, anxiety, cravings, ADHD, memory loss, fatigue, low libido, weight problems and addictions. Aging, chronic stress, nutritional deficiencies, environmental toxins and alcohol and drug abuse are believed to be primary contributors to neurotransmitter imbalances. Many medications are designed to address symptoms of illness by effectively targeting and altering neurotransmitter activity. The identification and function of neurotransmitters remains an open field of scientific study. However, we do now know that a single neuron can produce several different neurotransmitters.

Some of the more familiar identified neurotransmitters include:

Dopamine – Dopamine functions as both an inhibitory and excitatory neurotransmitter and is critical for memory and motor skills. Dopamine plays a role in behavior, learning, sleep, mood, focus, attention, immune health and pleasurable reward. Pleasurable situations, such as eating and sexual activity, stimulate the release of dopamine. Abnormal dopamine levels are associated with attention deficit, exhaustion, Parkinson’s disease and Obsessive Compulsive Disorder (OCD). Certain addictive drugs, such as cocaine and amphetamines, inhibit the re-uptake of dopamine, increasing the amount of dopamine in the reward centers. Stimulants, such as prescription medications that address symptoms of ADD and ADHD, temporarily address symptoms of low dopamine.

GABA – As the major inhibitory neurotransmitter widely distributed in the brain, GABA is considered a significant mood modulator. When GABA levels are too low or GABA action is impaired, neurons can become overexcited, which can lead to restlessness, anxiety and irritability. The natural function of GABA is to reduce any overactivity or over-excitability of neurons throughout the nervous system, promoting calmness and relaxation and decreasing brain activity. GABA aids neurons in recovery after firing, helping to reduce anxiety and worry. Pharmaceuticals that enhance GABA action are used to treat anxiety, seizures, restless sleep and other neurological or psychological disorders.

Glutamate – The most common neurotransmitter in the central nervous system, glutamate is an excitatory relative of GABA that is involved in most aspects of brain functioning, including cognition, learning and memory. Glutamate is considered a major mediator of excitatory signals, regulating brain development as well as the elimination and formation of nerve synapses. Glutamate is located within the cells, where it remains relatively inactive until needed. It is released in highly controlled amounts and is quickly taken back into the neuron once the message has been delivered. High levels of glutamate are actually toxic and can inflict massive neuron damage if spilled into brain tissue, such as when caused by a stroke or traumatic brain injury.

Serotonin – Present in the brain and digestive tract, inhibitory neurotransmitter Serotonin has been identified as an important factor in mood, depression, anxiety, sleep quality, emotions and the regulation of appetite and body temperature. Serotonin imbalances are involved in depression, impulsive behavior, sleep and emotional disorders, increased appetite and aggressiveness. Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed medications that ease symptoms of depression and anxiety. Pharmaceuticals that help people with depression work by preventing neurons from mopping up excess serotonin.

Acetylcholine (ACh) – This widely distributed excitatory neurotransmitter was the first neurotransmitter to be identified. ACh triggers voluntary muscle contraction, controls the heartbeat and stimulates the excretion of certain hormones. Research suggests that ACh may be critical for sleep, attentiveness, sexuality and memory. Alzheimer’s disease is associated with a lack of ACh in certain brain regions. Medications that increase ACh in the brain are the primary drugs used to treat Alzheimer’s disease.

Norepinephrine – Also known as nor-adrenaline and widely distributed throughout the body, norepinephrine acts as a neuromodulator, optimizing brain performance. As part of the body’s fight or flight response, norepinephrine quickly provides an accurate assessment of danger or stressful situations. Excessive amounts of this chemical, especially when no actual danger exists, can leave you anxious and hyperactive, while moderately low amounts have beneficial effects on sleep, concentration, inflammation and stress resilience.

Epinephrine – Widely known as adrenaline, epinephrine is both a neurotransmitter and a hormone that is essential to metabolism, attention, mental focus and our innate response to stress, fear, anger, panic or excitement. Synthesized from norepinephrine and released by the adrenal glands, epinephrine results in a state of hyperawareness followed by an energy surge that quickens the heartbeat, strengthens the force of the heart’s contraction and opens air passages in the lungs. Abnormal levels of epinephrine are linked to sleep disorders, anxiety, hypertension and lowered immunity.

The importance of neurotransmitters cannot be understated. Neurotransmitters control our wondrous and highly complicated human body, including our thought patterns, senses, moods, breathing, heart rate, appetite, digestion, voluntary and involuntary movement, reflexes, hormones, emotions, desires, memories, obsessions and personality. Nutritional support for neurotransmitter synthesis includes amino acids, fundamental building blocks of neurotransmitter production. Turmeric, glutathione, NAC, selenium and magnesium all support neurotransmitter activity. In addition, 30 minutes of daily exercise is believed to boost brain serotonin levels.
