GAD-25 Activators

GAD-25 Activators encompass a range of chemical compounds that facilitate the enhancement of GAD-25's catalytic conversion of glutamate into gamma-Aminobutyric acid (GABA). Pyridoxal phosphate, a vital cofactor of GAD-25, directly augments its functional activity, ensuring the enzyme's optimal catalytic performance. Glutamate, the very substrate GAD-25 acts upon, inherently increases the enzyme's activity by providing the necessary component for GABA synthesis, while L-Theanine and Taurine potentially raise the substrate availability, further bolstering GAD-25's role in GABA production.

Vitamin B6 is essential for the synthesis of pyridoxal phosphate, thus indirectly enhancing GAD-25 functionality by ensuring a consistent supply of the active cofactor. Magnesium and Zinc ions both contribute by modulating GABAergic neurotransmission in manners that can result in the allosteric enhancement of GAD-25, suggesting a more subtle yet significant influence on the enzyme's activity. Additionally, certain nutrients and extracts such as Niacinamide and Ginkgo biloba extract indirectly contribute to the upregulation of GAD-25's activity.
