Magtein (Magnesium L-Threonate)
Magtein (Magnesium L-Threonate) is a patented magnesium compound specifically designed to cross the blood-brain barrier and increase brain magnesium levels by 15%. It enhances synaptic plasticity and neuroplasticity through NMDA receptor modulation, supporting memory formation and cognitive function.

Origin & History
Magtein is a patented form of magnesium L-threonate, developed to enhance magnesium delivery to the brain. It is produced through a proprietary process that increases its bioavailability.
Historical & Cultural Context
Magnesium has been used traditionally for its calming effects, but Magtein specifically targets brain health, a modern innovation in magnesium supplementation.
Health Benefits
- Enhances cognitive function: Magtein is the only magnesium form shown to cross the blood-brain barrier, improving memory and learning. This supports brain health and cognitive longevity. - Reduces anxiety and stress: By increasing magnesium levels in the brain, Magtein helps regulate neurotransmitters, reducing anxiety symptoms. This promotes a calm and balanced mood. - Supports sleep quality: Magnesium is essential for the production of melatonin, the sleep hormone, enhancing sleep quality and duration. This ensures restful nights and rejuvenated mornings. - Boosts brain plasticity: Magtein increases synaptic density, supporting brain plasticity and adaptability. This is crucial for learning and memory retention. - Improves attention and focus: By modulating neural pathways, Magtein enhances attention span and focus. This is vital for productivity and mental clarity. - Supports neurological health: Magtein helps protect against neurodegenerative diseases by reducing oxidative stress in the brain. This supports long-term brain health. - Enhances energy metabolism: Magnesium is involved in ATP production, the energy currency of cells, boosting overall energy levels. This is essential for maintaining an active lifestyle.
How It Works
Magtein increases brain magnesium concentrations through enhanced transport across the blood-brain barrier via the threonate moiety. Elevated brain magnesium enhances NMDA receptor function and synaptic plasticity, promoting long-term potentiation (LTP) essential for memory formation. The compound specifically targets hippocampal neurons, increasing synaptic density and improving communication between brain cells.
Scientific Research
Research, including randomized controlled trials, suggests Magtein effectively crosses the blood-brain barrier, improving cognitive function and memory in animal and human studies.
Clinical Summary
Human clinical trials demonstrate that 2 grams daily of Magtein for 12 weeks improved memory test scores by 13.1% in adults aged 50-70. Animal studies show 15% increases in brain magnesium levels and enhanced performance in memory tasks. However, human research is limited to small-scale studies with fewer than 50 participants. More large-scale, long-term clinical trials are needed to confirm cognitive benefits across diverse populations.

Safety & Interactions
Magtein is generally well-tolerated with mild side effects including drowsiness, headache, and loose stools at doses above 2 grams daily. It may enhance the effects of medications that depress the central nervous system, including benzodiazepines and sleep aids. Individuals with kidney disease should consult healthcare providers before use due to magnesium accumulation risks. Safety during pregnancy and breastfeeding has not been established through clinical research.
