Magtein

Liposomal Magtein is a next-generation brain magnesium formula delivering 1,000 mg of Magtein (Magnesium L-Threonate), the only form of magnesium clinically shown to cross the blood-brain barrier, alongside 450 mg of high-purity Phosphatidylcholine per serving, in Quicksilver Scientific's proprietary liposomal delivery system, designed to elevate brain magnesium concentrations, support cognitive function, memory, learning, neural plasticity, relaxation, stress resilience, and deep restorative sleep through a delivery system that makes this the most bioavailable and most brain-targeted liquid magnesium L-threonate supplement available. Magnesium L-Threonate is not simply another form of magnesium. It was developed specifically at MIT through research aimed at solving a fundamental problem with all other magnesium forms: the blood-brain barrier tightly regulates which substances pass from the bloodstream into the central nervous system, and standard magnesium forms including glycinate, citrate, malate, and oxide do not cross this barrier in meaningful amounts regardless of systemic blood magnesium levels. Magtein achieves blood-brain barrier crossing through the L-threonate component, a Vitamin C metabolite that acts as a transporter enabling magnesium delivery directly to neurons and synapses. Once in the brain, magnesium supports NMDA receptor regulation (critical for synaptic plasticity and learning), PGC-1 alpha mitochondrial biogenesis pathways in neurons, and the overall magnesium-dependent enzymatic activity that enables optimal neuronal communication. The phospholipid layer of this formula goes significantly beyond standard delivery function. At 450 mg of high-purity Phosphatidylcholine per serving, Liposomal Magtein provides a meaningful therapeutic dose of the primary phospholipid in neuronal cell membranes. Phosphatidylcholine is essential for maintaining the integrity and fluidity of the myelin sheath and neuronal membrane, supports acetylcholine synthesis for memory and neurotransmission, and directly nourishes the cellular structures that the Magtein is designed to support. This combination of brain-targeted magnesium with neuronal membrane phospholipid support in a single formula is what Quicksilver Scientific means when they describe this as a "high-octane" brain magnesium formulation. The liposomal delivery adds the third layer of clinical advantage. Standard Magtein capsules require intestinal absorption and systemic circulation before magnesium can reach the blood-brain barrier. Quicksilver's liposomal liquid begins absorbing through the oral mucosa during the 30 to 90 second sublingual hold, providing more rapid systemic delivery that translates to faster, more predictable brain magnesium support.Recommended split dosing: 5 mL during the daytime for cognitive support and 10 mL one hour before sleep for sleep and recovery support. This split-dose protocol mirrors the clinical research approach to Magtein dosing and optimizes both daytime cognitive benefit and nighttime sleep architecture support.

Key Benefits: Supports healthy brain magnesium levels via Magtein, the only magnesium clinically shown to cross the blood-brain barrier Supports cognitive function, mental clarity, focus, and processing speed Promotes healthy memory formation, consolidation, and retrieval Supports healthy learning capacity and synaptic plasticity via NMDA receptor magnesium modulation Promotes relaxation, stress resilience, and healthy mood stability Supports deep, restorative sleep quality and healthy sleep architecture 450 mg Phosphatidylcholine per serving provides neuronal membrane phospholipid support alongside brain magnesium delivery Phosphatidylcholine supports acetylcholine synthesis for neurotransmission and memory Liposomal delivery begins absorbing in the mouth for more rapid brain delivery vs capsule Magtein Double-delivery advantage: liposomal delivery plus Magtein blood-brain barrier crossing Recommended split-dose protocol: 5 mL daytime for cognitive support, 10 mL before bed for sleep support Vegan, gluten-free, soy protein-free, sugar-free, non-GMO No artificial colors or flavors What's Inside — Full Supplement Facts (per 15 mL daily serving): Magnesium (Elemental) — 72 mg (from 1,000 mg Magnesium L-Threonate as Magtein) — Magtein is a patented form of Magnesium L-Threonate developed at MIT, protected under a family of U.S. patents and distributed exclusively by Threotech LLC. The 1,000 mg dose of Magnesium L-Threonate provides 72 mg of elemental magnesium alongside the L-threonate transporter that enables blood-brain barrier crossing. Human clinical research on Magtein demonstrates increases in brain synaptic density, improvements in working memory and long-term memory recall, support for cognitive performance, and benefits for sleep quality at therapeutic doses. The liposomal delivery system provides a double bioavailability advantage: Quicksilver's phospholipid encapsulation begins oral mucosal absorption before the compound reaches the intestine, and the Magtein itself is designed to cross the blood-brain barrier after reaching systemic circulation. Together these two mechanisms provide the most direct and efficient route to neuronal magnesium support of any magnesium supplement format. Phosphatidylcholine (from Highly Purified Phospholipids) — 450 mg — A therapeutic dose of the primary phospholipid in neuronal cell membranes, myelin sheath, and the liposomal delivery vehicle itself. Phosphatidylcholine at this dose provides direct neuronal membrane phospholipid support, contributing to membrane integrity and fluidity that are essential for efficient synaptic transmission and neurotransmitter receptor function. As a choline source, phosphatidylcholine also supports acetylcholine synthesis, the neurotransmitter essential for memory consolidation and cognitive function. The 450 mg dose per serving is approximately 9 times higher than the phosphatidylcholine provided in a typical liposomal delivery system, reflecting Quicksilver's deliberate decision to include it as a therapeutic brain health ingredient rather than simply a delivery excipient. Other Ingredients: Water, Glycerin, Ethanol, Acacia Gum, Natural Citrus Oils, Citric Acid. Storage Store at room temperature out of direct sunlight. No refrigeration required. Use within 6 months of opening. Keep out of reach of children. Directions Recommended split-dose protocol: Take 5 mL during the daytime for cognitive and focus support. Take 10 mL approximately one hour before sleep for sleep and recovery support. Hold in mouth for 30 to 90 seconds before swallowing. Best taken on an empty stomach at least 10 minutes before meals for optimal mucosal absorption.If pregnant, breastfeeding, or taking prescription medications, consult your healthcare practitioner before use.
