Pro GAD Enhancer, created by a leading neuro-immune/genomic specialist , Kendal Stewart, MD, was created to assist patients who have difficulty producing adequate amounts of GABA, an important brain neurotransmitter. GABA plays the principal role of reducing excitability throughout the nervous system, as well as, regulation of muscle relaxation. Many patients possess a genetic mutation of GAD (Glutamic Acid Decarboxylase), the primary enzyme that creates GABA. A weakness in the GAD enzyme creates an increased amount of Glutamate, the primary excitatory neurotransmitter of the nervous system, and a relative deficiency of GABA. This imbalance creates an overly stimulated nervous system and traditional GABA should not be used.. The 5 key ingredients are designed to assist with: Patients with GAD gene mutations, those who are anxious or cannot relax, inability to sleep or stay asleep, poor mood.. Other nutritional cofactors are essential to the success of Pro GAD Enhancer L-Glycine is an essential amino acid, making it versatile for use in a wide range of functions. Glycine is necessary for the production of glutathione, DNA, creatine, bile, hemoglobin, and most proteins. Glycine also functions as a calming neurotransmitter in the brain, where it facilitates nerve impulses and is important for the maintenance of healthy sleep patterns.
