how does magnesium L-threonate function in MagMind?
A highly bioavailable magnesium that significantly increases magnesium levels in the brain.
Brain magnesium supports cognition and brain health
As the fourth most abundant mineral ion in the human body, magnesium (Mg) plays a diverse set of biological roles.
Best known for its importance to skeletal and cardiovascular health, Mg is essential to fundamental functions like energy generation and nucleotide stockpiling for DNA/RNA synthesis.
Magnesium levels also impact calcium (Ca) levels inside cells—as Mg levels decrease, Ca levels increase, imbalancing the cell’s electrolyte levels.
Such a state is associated with muscle cramps, blood-pressure imbalance, neurological deficiencies.
Nevertheless, an estimated 68% of Americans do not consume their recommended daily allowance for Mg. Some attribute this to modern dietary patterns. Others have observed that reduced magnesium levels can be attributed to food refining, processing and the use of industrial fertilizers, which typically lack magnesium.
A Plastic Brain!
It’s been known for some time that Mg increases energy availability in the brain while helping to contain neuronal excitability and maintain cognition. But the importance of Mg to memory has only begun to be elucidated in the past decade. In the jargon of neuroscience, Mg has significant effects on synaptic plasticity—or simply “plasticity.” But what does that mean?
Memory is formed through a complex set of processes that both increase the amount and enhance the strength of neuronal connections. The ability to adapt in this way or be molded like plastic) then paves the way for easier learning and better memory.
So a plastic brain is a healthly, elastic brain. And it appears that as magnesium levels rise, plasticity increases. As inverse evidence, prolonged reduction in dietary magnesium leads to impaired memory and brain function.

As noted above, a full 2/3 of Americans do not obtain adequate magnesium from their diets. On top of that, only about 5% of magnesium in the blood reaches the brain with typical forms of magnesium. So it’s important that a brain-directed magnesium supplement display both high efficiency in transporting Mg2+ from the digestive tract into the blood and from the blood into the central nervous system. When evaluated versus other forms of magnesium, such as magnesium chloride, citrate, glycinate and gluconate, the brain bioavailability and cognitive effects of magnesium L-threonate are beyond compare.
Magnesium L-threonate is able to increase levels of magnesium in the brain-brain barrier because it manages to cross the blood brain barrier. For Mg, this is a difficult feat. Active transport maintains a higher concentration of Mg2+ in cerebrospinal fluid compared to blood, but strictly limits how much Mg2+ can be loaded into the brain.
In rats, raising blood levels of Mg2+ 3-fold via intravenous infusion of MgSO4 for 5 days failed to elevate brain Mg2+ content at all. While in humans, increasing blood levels by up to 300% only leads to a 10- 19% increase in cerebrospinal fluid.
Clinically, increasing brain Mg2+ with magnesium L-threonate leads to some surprising effects. In both young and old rats learning and memory are altered, but the effects appear to be region specific.
In the hippocampus, changes occur that strengthen memories and facilitate learning. But in the amygdala, the seat of emotional memory, changes occur that seem to make it easier to “extinguish” fear associated with painful memories.
Mind at ease
Knowing the biochemical underpinnings of magnesium in the brain, it may not be surprising to learn that Mg deficiency has been associated with poor sleep quality and anxiety.
What happens in the brain undoubtedly affects the machinations of the mind. And raising brain levels with oral supplementation of magnesium may promote restful sleep and relaxation.
MagMind (magnesium L-threonate, or Magtein) is the only form of magnesium that has been shown by promising research to readily cross the blood-brain barrier and provide significant positive effects on cognition, memory and brain health.
MagMind may also improve relaxation and sleep quality.

Reducing salt intake, should you care?
In our last blog article I discussed the dangers of dehydration during a heat wave. It was also remarked how our bodies don't just lose fluid, but also lose salts. As if it isn't clear yet, you will not just need to drink more water during a heat wave, but also need to consume more salts.
Because we are are bombarded with well-intended advice to limit salt intake because the average person consumes too much salt by eating too much junkfood, you would almost forget how essential minerals are and more specifically, sodium is for our health.
Why we aren't supposed to eat so much sodium
When there’s extra sodium in your bloodstream, sodium pulls water into your blood vessels, increasing the total amount of blood inside your blood vessels. With more blood flowing through your blood vessels, blood pressure may increase too much.
Even if you don’t have high blood pressure, it is postulated that eating less sodium can help blunt the rise in blood pressure that occurs with age, and reduce your risk of heart attack, heart failure, stroke, kidney disease, osteoporosis, stomach cancer and even headaches.
The extra water in your body (from temporary high salt intake) can also lead to bloating which can feel very uncomfortable.
The power of positive thinking
Why is stress so hard on the body?When we are stressed, our bodies produce higher levels of cortisol, a hormone that shuts down the thinking center of our brains and activates conflict aversion and protection behaviors. We become more reactive and sensitive. We often perceive even greater judgment and negativity than actually exists. And these effects can last for 26 hours or more, imprinting the interaction on our memories and magnifying the impact it has on our future behavior. Cortisol can be self-inforcing, the more we think about a stressful event, the bigger and longer the impact.
Positive comments produce a chemical reaction too. They spur the production of oxytocin, a feel-good hormone that elevates our ability to communicate, collaborate and trust others by activating networks in our prefrontal cortex. But oxytocin metabolizes more quickly than cortisol, so its effects are less dramatic and long-lasting.
In order to counterbalance the effect of stress, a much higher amount of positive events must happen, which in the real world, is not so easy to achieve.
Another factor which makes it harder to achieve happiness, is that every individual has a 'happiness set point'.
A happiness set point is the point on a continuum of happiness with which we are born.
In early research it was concluded that positive events (such as winning the lottery) and negative events (such as an accident) change our happiness levels for a short period of time, until after a while, we return to the baseline, our happiness set point.
Lately though it has been shown that we *can* change our setpoint. This however, is not very easy and requires hard work!
So let's look at the factors that can help influence happiness!
Nootropics, what are they and how do they work?Nootropics is the accepted term for substances that enhance learning and memory function.
Nootropics work in various ways depending on the characteristic of the substance.
Some work by enhancing oxygen transport to the brain, an improved energy turnover in the brain, better neurotransmitter availability, or enhancing the creation of other substances that influence brain activity.
