Magtein 15.2 fl oz

Liposomal Magnesium L-Threonate Supplement for Brain and Cognitive Support

Magtein® 15.2 fl oz by Quicksilver Scientific delivers magnesium L-threonate — the only form of magnesium clinically demonstrated to cross the blood-brain barrier and increase brain magnesium levels — in a large-format liposomal liquid for daily cognitive and nervous system support. This liposomal magnesium L-threonate supplement combines the superior brain-delivery of Magtein with Quicksilver's absorption-enhancing liposomal technology.

Why Magnesium L-Threonate Is the Brain Magnesium of Choice

Most magnesium forms (glycinate, citrate, oxide) raise serum and tissue magnesium but do not reliably increase magnesium in the brain due to the blood-brain barrier. Magnesium L-threonate was specifically developed by MIT researchers to address this gap — using the threonate carrier to transport magnesium across the BBB and into neurons, where it supports synaptic density, memory, and cognitive resilience.

Key Features of This Magtein Formula

• Magnesium L-threonate — the only form clinically shown to raise brain magnesium
• Liposomal liquid for enhanced GI absorption and systemic delivery
• Supports cognitive function, memory, and synaptic plasticity
• Promotes healthy nervous system function and stress resilience
• 15.2 fl oz — large format for sustained daily cognitive support

Who This Is For

This liposomal magnesium L-threonate supplement is ideal for adults seeking brain-specific magnesium support for memory, focus, cognitive aging, or nervous system health — particularly those who haven't responded to standard magnesium forms.

How to Use

Take as directed by your healthcare provider, typically 1–2 teaspoons daily in water.
