Amino Acid and Neurotransmitter
| Neurotransmitter | Amino Acid (Building block) | Deficiency | Toxicity | Genetics or Natural Depletion | External/Chemical Source of Depletion | Present in Foods |
|---|---|---|---|---|---|---|
| Enkephalin (Opioids) | l-phenylalanine, glycine, methionine | A deficiency of glycine can result in: A deep sense of inadequacy, incompleteness. Reduced ability to combat physical pain | Excessive sedation, can be fatal if combined with other sedating agents. | Opioid levels passed from parents to offspring. Trauma reduces availability | All drugs effecting opioid system will eventually reduce natural supply if used for prolonged periods. | Glycine can be found in seafood, fowl, lima beans, ham |
What is Glycine?
Glycine is both a protein amino acid and a neurotransmitter in the central nervous system.
Glycine as a Supplement
Supplemental glycine has anti-spastic activity, as well as antioxidant and anti-inflammatory activities. Supplemental glycine works by inhibiting the messages from the spinal cord that cause abnormal responses such as jerky, exaggerated, spastic, or uncoordinated muscular movements, especially those that are often magnified during intense anxiety or in association with some withdrawal situations.
Glycine readily crosses the blood-brain barrier.
Always remember, before taking glycine or any other nutritional supplement, consult your health care professional first.
