The essentials

A closer look.

OptiMag Neuro by Xymogen is a magnesium L-threonate powder in a mixed berry flavor, formulated to support cognitive function, neurological health, and relaxation. Magnesium L-threonate is a chelated form researched for its ability to cross the blood-brain barrier more readily than other magnesium forms, making it a consideration for those seeking targeted brain and nervous system support.

Why It's Worth Considering: Xymogen is a practitioner-grade brand, and this formulation uses the specific L-threonate chelate studied for neuronal magnesium uptake, delivered as a convenient, flavored powder for flexible dosing.
