Part 4: One of the most powerful pain receptors in your nervous system is the NMDA receptor.
When activated, it amplifies pain signals and contributes to central sensitization, the process where the nervous system becomes overly responsive.
Magnesium naturally regulates this receptor.
It:
• Helps control excess glutamate
• Blocks excessive calcium influx
• Reduces abnormal pain signaling
In fact, magnesium binds to this receptor at a significant percentage of the strength of ketamine—one reason it has been studied in CRPS and post-surgical pain reduction.
If you feel like your nervous system is “stuck on high,” this mechanism is critical.
In this video, I break down:
• How NMDA receptors amplify pain
• Why centralized pain persists even after tissue healing
• Why magnesium may reduce morphine requirements post-surgery
