Liposomal Magtein® is an advanced dietary supplement in liquid form that combines magnesium L-threonate (Magtein®) with phosphatidylcholine (PC) in a liposomal formulation from Quicksilver Scientific. This composition has been developed to provide targeted support for brain function, sleep and stress management by means of superior bioavailability and efficient transport across the blood-brain barrier. Magtein® is the only form of magnesium that has been documented to increase magnesium concentration in the brain, while phosphatidylcholine contributes to neuronal membrane health and signal transmission.

Liposomal Magtein® has a number of documented and potential health benefits:

• Contributes to the reduction of fatigue and exhaustion (EFSA ID 280)

• Contributes to the normal functioning of the nervous system (EFSA ID 281)

• Contributes to normal muscle function (EFSA ID 282)

• Contributes to normal energy turnover (EFSA ID 283)

• Contributes to normal psychological function (EFSA ID 284)

• Contributes to the maintenance of normal bones and teeth (EFSA ID 285)

• Contributes to electrolyte balance (EFSA ID 286)

• Contributes to normal protein synthesis (EFSA ID 287)

• Has a role in the cell division process (EFSA ID 288)

• Can promote healthy sleep quality through the influence of neurotransmitters

• May support memory, focus, mental clarity and learning

• May contribute to neural adaptation and plasticity

• Can support the body's stress management and mood balance

• May help reduce brain fog and support cognitive performance

• Can support mitochondrial energy turnover in the brain

• May help protect brain cells against oxidative stress

• Can support liver health and detoxification processes

• Can support nutrient uptake and cell communication

Most documented effects

• Cognitive support: Helps maintain memory, focus and mental clarity

• Sleep and stress reduction: Supports relaxation and deeper sleep through the influence of GABA receptors and magnesium-dependent processes

Lesser known effect

• Neural plasticity: May support the formation of new synaptic connections in the brain and promote long-term neuroprotection
