The Interplay of Neurotransmitters & Mental States

The body is the theater for emotional and cognitive states. Whether mood or mental issues express themselves through behavior or physical functioning-neurotransmitters are one group of characters at play.

Memory and cognitive processes are heavily dependent on acetylcholine, a neurotransmitter known to decline with age.

Attention, learning, and mental focus require adequate stimulation with excitatory neurotransmitters, particularly

dopamine, and balanced levels of norepinephrine.

Sense of tranquility is influenced by the calming effects of GABA, an inhibitory neurotransmitter.

Feelings of nervousness are influenced by glutamate, an excitatory neurotransmitter.

Perception is influenced by a healthy neuronal environment, particularly by the balance between GABA and

glutamate.

Mood, stressful feelings, and sense of well-being are influenced by the level of brain cortisol-a neurohormone that can become elevated during times of stress, which may impact serotonin.

Feeling happy, content, and relaxed is related to the level of serotonin, which is a common target for modulation

in conventional approaches.

 

Sleep and wake cycles are dependent on melatonin status-a hormone derived from serotonin and produced

in the pineal gland.

 

Addressing neurological health concerns

An estimated 1 in 4 Americans have mental health concerns. Neurotransmitter modulation is the primary goal

to address neurological health with many conventional products - which are not without adverse effects. In collaboration with a renowned neurologist, Metagenics has developed a natural, clinically successful family of neurological health products designed to nutritionally support brain function to influence neurotransmitter dynamics associated with specific cognitive and emotional states. Your guide to specialized neurological support In this clinical guide, you'll find product descriptions, recommendations, and a quick reference tool explaining how to support various aspects of neurological health:

  • Neuroprotection
  • Forgetfulness
  • Distracted mind
  • Nervousness
  • Negative mood
  • Occassional sleeplessness
