Not all magnesium behaves the same once it’s absorbed.
The real difference is where it ends up 🧠
Most magnesium forms raise blood levels, but very few meaningfully increase magnesium inside the brain, where it regulates NMDA receptors, synaptic plasticity, and stress signaling.
The blood–brain barrier is selective. Forms bound to specific ligands cross more efficiently and remain bioavailable longer.
Why that matters neurologically:
🧠 Supports learning, memory, and synaptic strength
⚡ Stabilizes excitatory signaling (glutamate control)
🛌 Improves sleep architecture and neural recovery
🧬 Buffers stress-driven neural overactivation
If you’re taking magnesium “for calm” but still feel wired, foggy, or overstimulated, the issue usually isn’t the dose.
It’s delivery.
Save this if you care about brain-level effects! 🧠💪
