Aloha,
Great article. State of the art product. Currently using for the last 2 months. Memory is definitely improved. Who am I?? LOL..
Reversing Neurodegeneration with a New Magnesium Compound
By Martin Alessio†
In this article, you will learn of the vital role that magnesium plays in protecting the brain's structure and function and why conventional supplements don't deliver enough magnesium into the brain.
Researchers have found that a new highly absorbable form of magnesium called magnesium-L-threonate concentrates more efficiently in the brain, rebuilds ruptured synapses, and restores the degraded neuronal connections observed in some forms of memory loss.
In experimental models, magnesium-L-threonate induced improvements of 18% for short-term memory and 100% for long-term memory.(8)
Novel Magnesium Compound Halts Neurologic Decay
The neurodegenerative processes involved in memory loss results from deterioration of connectivity between brain cells but are not a "natural function" of aging.
Low magnesium status can accelerate brain cell aging and memory loss.
Standard magnesium offers limited protection to brain cells.
Magnesium-L-threonate is a new form of magnesium that dramatically boosts levels of magnesium in the brain.
Boosting brain magnesium with magnesium-L-threonate enhances synaptic density and plasticity, the structural basis of learning and memory.
In numerous experimental models, supplementation with magnesium-L- threonate has been shown to enhance memory and cognitive performance in multiple tests.
Magnesium Deficiency: An Overlooked Cause of Neurologic Decay
Half of all aging individuals in the developed world are magnesium deficient, a nutritional deficit that worsens over time.
Confirmatory data show that Americans are no exception.(9,10) For instance, American women consume just 68% of the recommended daily intake of magnesium.(11)
Magnesium has long been known as a key nutrient for optimal brain function. More recently, scientists have found it specifically promotes learning and memory as a result of its beneficial effect on synaptic plasticity and density.(7,8,12)
Magnesium works with calcium to modulate "ion channels" that open in response to nerve impulses, which in turn trigger neurotransmitter release. The most important of those channels is controlled by a complex called the NMDA receptor.(13,14) NMDA receptors play an important role in promoting neural plasticity and synaptic density, the structural underpinnings of memory.(15-17)
Magnesium deficiency can cause symptoms ranging from apathy and psychosis to memory impairment.(13,18) Insufficient magnesium slows brain recovery following injury from trauma(19) and in laboratory studies accelerates cellular aging.(20)
Ominously, magnesium deficiency may produce no overt symptoms in its initial stages.(21)
Part of the problem is that it is difficult for the body to maintain sufficiently high concentrations of magnesium in the brain.(8)
For this reason, researchers have long sought ways that higher magnesium brain concentrations might be achieved and sustained.
A Breakthrough Form of Magnesium
Scientists have been challenged to find a way to raise magnesium levels in the brain.(8) Even intravenous infusions cause only a modest elevation of magnesium levels in the central nervous system.(22)
An innovative team of researchers from the Massachusetts Institute of Technology (MIT) recently found a way to surmount this obstacle. They formulated a new magnesium compound called magnesium-L-threonate or MgT that in lab tests allows for oral administration while maximizing magnesium "loading" into the brain.(7,8)
Based on prior research, they meticulously documented that increased levels of magnesium in the brain promote synaptic density and plasticity in the hippocampus.(14) Up until now, however, no widely available forms of magnesium met the criteria needed for rapid absorption and efficient transfer into the central nervous system.(8)
By contrast, MgT yielded compelling results.
MgT oral supplements increased magnesium levels in spinal fluid, an index of measurement in brain magnesium by about 15%, while none of the other magnesium compounds tested produced significant elevations.(8) While a 15% increase may not sound like a lot, it induced a profound effect on neurological function.
To evaluate the effects of MgT on memory, the researchers tested it against currently available magnesium compounds. They used a simple assessment of learning and memory called the Novel Object Recognition Test or NORT. A high NORT score means that the animal is good at recognizing and identifying new objects, a skill that is critical in aging humans as well.(8) NORT is a good test of function in the hippocampus, which is rich in the NMDA receptors so closely controlled by magnesium.(23)
The researchers put aged animals through the NORT test, supplementing them with MgT or one of the commercially available magnesium compounds. Only MgT significantly enhanced both short- and long-term memory, boosting scores by 15% for short-term memory and 54% for long-term memory compared to magnesium citrate.(8)
Better Function of Memory-Forming Synaptic Connections
Given the effect of MgT in increasing synaptic density and plasticity in experimental animals (rats), the research team asked the obvious next question, "Do those changes lead to an increase in the number of neurotransmitter release sites, and, subsequently, to enhanced signal transmission?"(8) That, after all, is the hallmark of learning and memory.
Using high-tech microscopic measuring devices, the team demonstrated that the magnesium elevation in brain tissue observed in MgT supplementation increases the number of functioning neurotransmitter release sites.(8) This effect could be likened to increasing the number of soldiers on the battlefield: when the call to action comes, a much larger force is prepared to perform.
The final question to be addressed in this series of studies was whether the increased density of synaptic connections directly correlated with the observed improvements in memory created by MgT supplementation.
The researchers systematically plotted out the time-course of the increase in synaptic density following MgT supplementation, and found that it directly paralleled the improvements in memory.(8) They also found that when MgT supplementation was stopped, the density of synaptic connections dropped back to baseline, further confirming the correlation. They found that MgT supplementation boosted all of the animals' performance, not just average performance.
Improvement in Spatial Short-Term Memory
Spatial working memory is an essential memory function, helping you remember where things are and where you are in relation to the world over the short term. It is working memory that enables you to find your car keys as you head out the door or return to the correct page in the magazine you were reading a few minutes ago.
The MIT researchers tested spatial working memory in experimental animals. Without treatment, both young and old animals forgot the correct choice about 30% of the time. After 24 days of MgT supplementation, however, both young and old animals had improved this measurement of memory performance by more than 17%.(8)
Even more impressive, by 30 days of supplementation, the older animals' performance became equal to that of their younger counterparts. Since the older animals were more forgetful at baseline than the younger animals that meant that the older animals had a larger percentage memory improvement (nearly 19%) than the younger animals' more modest 13%.(8)
When MgT supplementation was suspended, the memory-enhancing effects persisted in younger animals, but in older animals spatial working memory performance declined dramatically, returning to baseline within 12 days.(8) When MgT supplementation to the older animals was resumed, however, their memory performance was restored in 12 days.
In other words, magnesium-L-threonate improved memory in both old and young animals, but had a substantially greater effect on aged individuals - the very ones most in need of memory enhancements.
Enhanced Spatial Long-Term Memory
Long-term spatial memory is crucial for older individuals. It's how you remember where you live or how to get to the grocery store. Loss of spatial long-term memory is one of the main reasons that older people with dementia get lost running even simple errands.
To test spatial long-term memory in MgT-supplemented animals, the researchers used a maze that required the animal to swim and find a submerged platform on which to rest. Again, both old and young animals supplemented with magnesium-L-threonate learned significantly faster than untreated animals during the training sessions.(8)
One hour after the training period, the researchers removed the submerged platform, causing the animals to have to search for its last location. Both young and old supplemented and unsupplemented animals remembered where the platform had been over the short term and were searching for it in the correct quadrant of the maze.
But after 24 hours, a remarkable difference was observed. Untreated animals, both young and old, completely forgot where the platform had been hidden, randomly searching in all quadrants of the maze. Supplemented animals, on the other hand, continued to search in the correct part of the maze more than twice as long as they looked in incorrect areas.(8) That translated into improvements in spatial long-term memory of 122% in younger supplemented animals, and nearly 100% in older supplemented animals.
In short, MgT supplementation doubled the accuracy of long-term spatial memory in older animals, and more than doubled it in younger animals.
Better Recall
One critical memory function is the ability to bring up an important memory based on only partial information, a function called pattern completion.(8) You use pattern completion memory to find your way around a familiar neighborhood after dark or following a heavy snowstorm. In both cases, some familiar cues are gone, but a healthy brain will fill in the missing details by completing a recognizable pattern.
As decsribed earlier, when researchers removed some of the external visual cues from the water maze, younger animals had no particular difficulty finding their way to the hidden platform during the first 24-hour period. Older animals, on the other hand, demonstrated substantial impairment when familiar cues were missing, spending more than twice as much time searching for the missing platform. When given MgT for 30 days, however, older animals performed as well as the younger ones, quickly finding the platform even when many of the external cues were unavailable.(8)
In human terms, this kind of improvement could mean the difference between a routine trip to the grocery store at dusk versus getting lost in the dark.
Having successfully demonstrated that magnesium-L-threonate (MgT) improves multiple forms of learning and memory in living animals, the research team sought to explore the cellular and molecular basis of that improvement. They wanted to understand in a detailed fashion just what changes the MgT was producing in the brains of older animals that helped them form stronger, more stable memories.
What they determined was compelling.
Increased Brain Cell Signaling
The first step was to determine the effects of MgT supplementation on signaling between brain cells mediated by what are known as NMDA receptors. These receptors operate through varying concentrations of calcium and magnesium in brain tissue, making them a logical point of observation.
The first finding was that MgT treatment in animals resulted in stronger signaling at essential brain cell synapses.(8) This increase in signaling was accomplished by a 60% increase in production of new NMDA receptors and by increases of up to 92% in related proteins that play essential supporting roles in brain signal transmission.(8)
Higher Memory-Forming Synaptic Plasticity and Density
Synaptic plasticity, or the ability to rapidly change the number and strength of brain cell synapses, is critical to the brain's ability to form, retain, and retrieve memories. The research team compared synaptic plasticity in the brains of MgT-supplemented animals versus controls.(8)
They found that production of a very special subunit of the NMDA receptor, one closely associated with synaptic plasticity, was selectively enhanced by MgT supplementation.(8) This molecular change is known to cause potent long-term increases in synaptic strength, and hence a greater capacity for information storage and memory.(8,24-26)
The result of these increases in NMDA receptor numbers was a 52% enhancement in long-term potentiation,(8) which is the cellular equivalent of memory formation in the brain tissues of MgT-supplemented animals.(27,28)
Memory depends not only on synaptic plasticity, but also on the healthy physical structure of synapses between brain cells. Unfortunately, synaptic connections in the memory-rich hippocampus region of the brain decline with aging, which directly correlates with memory loss.(8,29,30,31)
One of the most vital structures to be found at brain cell synapses is the synaptic bouton, from the French word for button. When an electrical impulse reaches a pre-synaptic bouton, and ample calcium and magnesium are present, neurotransmitters are released to transmit the impulse to the next neuron in line. The greater the number and density of synaptic boutons, the stronger the electrochemical signal that the synapse can produce, and the more sustained the memory that is created.(32)
When the researchers examined the brains of control and MgT-supplemented animals under a high-power microscope, they readily detected much greater densities of synaptic bouton proteins in tissues from the supplemented animals. Those proteins are essential for neurotransmitter release in the several regions of the hippocampus vital for memory formation and retrieval.(8) Remarkably, the density of the synaptic boutons was closely correlated with the memory performance of each individual animal on the novel object recognition test.
Summary
The neurodegenerative processes involved in memory loss result from deterioration of connectivity between brain cells but are not a natural function of aging. Memory loss is now known to be associated with loss of synaptic density and plasticity in the brain. Low magnesium levels may contribute to such losses.
Magnesium-L-threonate (MgT), a new magnesium compound, boosts brain magnesium levels better than standard supplements. Studies reveal that MgT produces dramatic increases in synaptic density and plasticity, resulting in similar improvements in memory function itself.
