Cellular Transporter & Kinetic Mechanism

Chelated to L-threonic acid, a metabolite of ascorbic acid that specifically enhances magnesium transport across the blood-brain barrier into cerebral spinal fluid.

Primary Physiological Indication

Magnesium L-Threonate: indicated for Synaptic plasticity, slow-wave sleep density, cognitive clarity. Primary intestinal absorption via Passive Diffusion + SLC41A1 / Crosses BBB directly.

01

Elemental Yield vs Salt Mass

Commercial labels often advertise gross salt weight (e.g. 2,000 mg Magnesium L-Threonate) rather than elemental mineral yield (144 mg Mg). Our engine calculates actual elemental delivery so you can match clinical study endpoints.

02

Intestinal Barrier Transporters

Inorganic salts compete for saturable divalent cation channels (TRPM6) and induce hyperosmotic diarrhea. Amino acid chelates (bisglycinate) use PEPT1 dipeptide carriers, while threonate crosses cell membranes via passive diffusion.

03

Cerebrospinal Permeability

Most standard minerals fail to elevate cerebrospinal fluid (CSF) concentrations because the blood-brain barrier tightly regulates ion transit. Magnesium L-threonate was engineered specifically to penetrate brain tissue and augment synaptic density.
