In this episode with neuroscientist Dr. Guosong Liu, you’ll explore his accidental discovery at MIT's Center for Learning and Memory that led him down a two-decade journey into brain magnesium, synaptic plasticity, and cognitive decline. That research ultimately resulted in the invention of Magtein® (magnesium L-threonate), a compound he engineered to cross the blood-brain barrier in a way other magnesium forms cannot, with clinical trials showing a reversal of nine years of cognitive decline, measurable shifts in sleep architecture, stress reduction in as little as three days, and meaningful improvements in prefrontal cortex function at just 140 milligrams per day. Dr. Liu also shares what his current Alzheimer's prevention research looks like.

Dr. Liu is a world-renowned neuroscientist whose pioneering research on brain magnesium has transformed our understanding of cognitive function and synaptic plasticity. With more than 25 years of neuroscience expertise, he previously served on the faculty at MIT's Picower Institute for Learning and Memory, founded the Center for Learning and Memory at Tsinghua University, and earned his Ph.D. in Neurophysiology from UCLA. His translational research has bridged laboratory discovery and human clinical application, resulting in multiple trials demonstrating Magtein's efficacy in supporting cognitive performance.

Magtein is the patented, clinically studied form of magnesium L-threonate designed to cross the blood-brain barrier and support memory, focus, mood, sleep quality, and stress resilience. Featured in more than 400 products across 40-plus countries, it is the global standard in brain-support magnesium nutrition.

Mindsip insights from this episode:

Weaken neural connections to alleviate trauma impact

Synaptic plasticity can be decreased to weaken neural connections, which is useful for therapies aimed at reducing the impact of negative memories like PTSD.

Yellow Flower

Experience mood improvements in days, achieve cognitive benefits in months

The effects on mood and anxiety can be felt in as little as three days, while maximum cognitive benefits take about three months to manifest.

Rethink blood tests for accurate magnesium assessment

Standard blood tests are not effective for measuring functional magnesium levels because it's the intracellular ionized magnesium in brain cells that matters, which is very difficult to quantify.

Enhance sleep quality with magnesium L-Threonate

Magnesium L-Threonate improves sleep quality by increasing deep and REM sleep while decreasing light sleep, though it may not increase total sleep time.

Utilize threonate to deliver magnesium to brain synapses

Threonate is the key component that acts like a 'gun' to deliver the magnesium 'bullet' into the brain's synaptic terminals where it's needed most.

Reverse cognitive decline with Magnesium L-Threonate supplementation

In a human clinical trial, Magnesium L-Threonate supplementation was shown to reverse nine years of age-dependent cognitive decline.

Increase brain magnesium for enhanced intelligence

The ratio of magnesium in the brain relative to the body is higher in more intelligent animals, with humans having a particularly high concentration.

Utilize magnesium L-threonate for vitamin C benefits

The threonate in Magnesium L-Threonate is a metabolic byproduct of Vitamin C, which is naturally present in the body.
