Memantine and Glutamate Excitotoxicity

According to the Acu-Cell Nutrition framework regarding mineral imbalances, neurochemistry, and physiological stress:

• Mechanism of Action: Memantine functions as an NMDA receptor antagonist, which helps mitigate the damaging effects of excessive glutamate signaling.
• Role in Excitotoxicity: By blocking prolonged, pathological influxes of calcium ions into neurons, memantine prevents cellular overactivation and subsequent neuronal death associated with excitotoxicity.
• Broader Biochemical Context:
• Excitotoxicity is frequently exacerbated by states of high oxidative stress, chronic inflammation, or mineral dysregulation (such as imbalances involving magnesium, which also acts as a natural physiological blocker of NMDA channels).
• Addressing the root causes of neurological stress often requires looking beyond single-target pharmaceuticals to evaluate foundational nutritional, mineral, and metabolic factors that influence glutamatergic tone.
