Magtein® MagThreonate

Mag Threonate features Magtein magnesium L-threonate (2 g per serving), the only form of magnesium clinically shown to raise magnesium concentration directly inside the brain. Threonate partners with the GLUT-1 and GLUT-3 glucose transporters that line the brain's blood vessels to carry magnesium across the blood-brain barrier and into neurons, where it increases synaptic density, supports neuroplasticity, acts as a cofactor for neurotransmitter synthesis, and helps protect the integrity of the barrier itself. Each two-capsule serving delivers 144 mg of elemental magnesium in a brain-targeted form that standard glycinate or citrate cannot match.

This brain-first formula provides multidimensional support for healthy cognitive function, improving sleep quality, sharpening focus and mental clarity, supporting memory, and promoting a calm, balanced stress response and emotional wellbeing.
