Magtein | Magnesium L-Threonate
Magnesium L-Threonate is a breakthrough form of magnesium that effectively crosses the blood-brain barrier, making it ideal for cognitive support, sleep quality, and neurological recovery. It has been shown to increase brain magnesium levels, which are critical for synaptic plasticity, memory formation, and calm brain activity.
Magtein®, the patented form of Magnesium L-Threonate used in clinical studies. It’s ideal for individuals looking to improve focus, reduce stress, and support deep, restorative sleep without sedation.
Function:
- Magnesium helps to facilitate muscle contraction, regulate blood pressure, and synthesize DNA and proteins
- Can penetrate the blood-brain barrier at higher levels than other forms of magnesium, which makes it the most bioavailable magnesium for the brain
- Aids in the transmission of nerve signals, regulates neurotransmitter levels, and fuels energy production in brain cells
- Supports enzyme reactions, nerve health, protein synthesis, and muscle function
Benefits:
- Enhances the quality of sleep and produces a calming effect
- Helps support cognitive function including memory, learning, attention, and focus
- Helps increase magnesium levels in the brain which may promote cognitive performance and overall brain health
Take 3 capsules 30-60 minutes before sleep
