Magnesium Threonate BBB Permeability

2025-02-22//READ: 5 MIN//BY CHEMGRADE RESEARCH

The Blood-Brain Barrier Problem

Magnesium is a critical dampener of neuronal firing. However, most forms (Oxide, Citrate, Glycinate) are primarily absorbed into muscle or bone. They struggle to cross the tight junctions of the Blood-Brain Barrier (BBB), making them less effective for "racing thoughts" or neurological anxiety.

The L-Threonate Carrier

Magnesium L-Threonate is unique. The Threonate metabolite acts as a carrier, actively transporting magnesium ions across the BBB. Studies show it elevates cerebrospinal fluid magnesium levels significantly higher than other forms, directly modulating NMDA receptors to reduce neuronal excitability.

Usage Note

Magnesium Threonate is expensive. Use it specifically for Cognitive/Anxiety-based insomnia. For general physical relaxation, Bisglycinate is sufficient.
