Liposomal Magtein® – liquid liposomal magnesium L-threonate for brain, sleep and stress balance

Liposomal Magtein® is an advanced liquid dietary supplement developed by Quicksilver Scientific, which combines magnesium L-threonate (Magtein®) with phosphatidylcholine (PC) in a liposomal delivery platform. This formulation is designed for high bioavailability and efficient transport to the nervous system, including across the blood-brain barrier. Magtein® is the only form of magnesium that has been shown in published research to increase magnesium concentration in the brain, while phosphatidylcholine is a central building block in neuronal cell membranes and signal transmission. The product has been developed for adults who want support for cognitive function, sleep quality, stress management and general neural health as part of a healthy lifestyle. 🧠✨

Health effects and physiological support
Magnesium is an essential mineral with a number of EFSA-approved health claims, and liposomal Magtein® is formulated for targeted support of the nervous system and brain.

• 🧠 Contributes to normal psychological function (EFSA ID 284)
• ⚡ Contributes to normal energy turnover and reduction of fatigue and exhaustion (EFSA ID 280, 283)
• 🧘 Contributes to normal functioning of the nervous system and muscle function (EFSA ID 281, 282)
• 🦷 Contributes to the maintenance of normal bones and teeth (EFSA ID 285)
• 💧 Contributes to electrolyte balance and normal protein synthesis (EFSA ID 286, 287)
• 🔬 Has a role in the cell division process (EFSA ID 288)

In addition to the approved claims, magnesium L-threonate has been investigated in the scientific literature in connection with:
• improved sleep quality and relaxation 😴
• support for memory, focus, mental clarity and learning 📚
• neural adaptation and synaptic plasticity 🔄
• support for stress management and mood balance 🌿
• reduction of subjective brain fog and mental fatigue
• support for mitochondrial energy turnover in brain cells
• protection of nerve cells against oxidative stress
• support for liver function, detoxification processes and cell communication

Top 2 most documented effects
• 🧠 Cognitive support: Magtein® has been researched for its role in supporting memory, focus and mental clarity through increased magnesium availability in the brain.
• 😴 Sleep and stress: Magnesium is involved in GABA-dependent processes and neural relaxation, and can support deeper and more restorative sleep.

Lesser known but interesting effect
• ✨ Neural plasticity: Preclinical and clinical studies indicate that magnesium L-threonate can support synaptic density and long-term neuroprotection, which is central to learning and cognitive resilience over time.
