People talk a lot about calcium and its importance in good health, and
while calcium is important, there is another equally important mineral
required to balance calcium in the body. That mineral is magnesium.
Both calcium and magnesium are present in all cells and particularly in
heart and artery muscle cells. While calcium stimulates muscle fibers to
tense and contract, magnesium stimulates muscles to loosen and relax.
Magnesium also regulates the amount of calcium that enters the cells. Without the balancing influence provided by magnesium, calcium will
cause the arteries, especially the arteries to the heart and brain, to tense up,
constricting the flow of blood to the brain and heart. The result can be high
blood pressure, heart attacks, stroke and migraine headaches.
Magnesium
deficiencies can also lead to thrombosis, calcium oxalate kidney stone
formation, uncontrollable muscle tics and premenstrual syndrome symptoms
such as nervousness and a craving for sweets.
Magnesium deficiency appears to play a key role in diseases of the
circulatory system.
Magnesium deficiencies have been associated with
such circulatory problems as arrythmias, congestive heart failure, angina
pain, strokes, hypertension, high LDL cholesterol levels, epilepsy and
migraine headaches.
Heart tissue in particular is sensitive to drops in
magnesium. Remember that magnesium balances the contracting effect of
calcium in muscles. Calcium is important for heart contraction, magnesium
for its relaxation. Magnesium is anti-arrhythmic, regulating heart electrical
activity. In addition, a deficiency can cause cardiac vulnerability to
cardiotoxic agents. Magnesium is significantly reduced in cardiac tissue
following a heart attack

Magnesium is also important for the brain.
It has been called the antistress
mineral, because it has a calming, relaxing effect on nerve function.
Furthermore, stress affects magnesium levels. High level achievers (known
as Type A individuals) release more fatty acids into their blood than relaxed
individuals (Type B personality). This results in a net loss of serum
magnesium for the Type A individuals. Furthermore, the importance of
magnesium to the nervous system is demonstrated by the fact that deficiency
symptoms include such brain and nerve related problems as mental
confusion and disorientation, depression, nervousness and easily aroused
anger.
Do Americans obtain enough magnesium in their diets?
The official
recommended daily allowances of the Food and Nutrition Board of the
National Research Council are 300 mg. per day for women and 350 for men.
However, some researchers feel the recommendation should be higher,
perhaps 400 or even 450 mg. per day. It has been estimated that the typical
American diet supplies 120 mg. of magnesium per 1,000 calories. On a
3,000 calorie per day diet, that’s barely enough.
Supplementation with magnesium may be particularly useful for persons
with circulatory problems. As we noted before, magnesium levels are
depleted following a heart attack. Furthermore, studies suggest that magnesium
supplements can do the same thing that the calcium channel blockers
commonly prescribed following a heart attack can do.
Since magnesium forms part of the chlorophyll molecule, green leafy
vegetables are excellent sources of magnesium. Other good sources include
nuts, beans, legumes, whole grains, seafood, dairy products and bitter herbs.
Magnesium I-threonate
A Spectacular Help for Improving Memory and Brain Function
Dr. Guosong Liu, M.D2 Ph.D., recently presented the following information at Nature's Sunshine's National Convention in Hawaii. Dr. Liu is Professor and Founding Director of the Center for Learning and Memory at the School of Medicine at Tsinghua University in Beijing; Adjunct Professor of the Center for Learning and Memory at the University of Texas in Austin; and Former Professor at the Department of Brain and Cognitive Science and the Department of Biology at MIT.
As people age, their brains age too.
Science has shown that certain portions of the brain, namely the prefrontal cortex and hippocampus, shrink as we age. Our computation skills slow. Our spatial orientation, verbal memory, perceptual speed and inductive reasoning all decrease, the last three of these decrease dramatically.
Researchers have found that the number of synapses (spaces between nerve endings where brain chemicals transfer information) decreases with age. In order to recover lost ability, we need to regrow synapses in both the prefrontal cortex and the hippocampus.
Scientists had already discovered that aging people and those with dementia had a lot less magnesium in their brains than younger people. They theorized that increasing brain levels of magnesium might enhance synaptic activity and thus improve brain function.
Dr. Liu and his colleagues at MIT found that magnesium I-threonate (MgT), a vitamin C metabolite of magnesium, is indeed able to penetrate into the hippocampus and prefrontal cortex the two areas of the brain known to shrink with age. After administering MgT to rats and mice for a period of time, they measured a 50% increase in the number of synapses! Further animal testing showed that MgT enhances learning and both short- and long-term memory in young and
aging rats. Dr. Liu and his fellow researchers also found that MgT does not enhance or impair fear memories (or increase bad memories) as MgT helped reduce anxiety-like behavior and learned helplessness. Dr. Liu theorized that this nutrient might be useful for people with post-traumatic stress disorder (PTSD).
In 2003, the Journal of Nutrition reported that half of the US population may be magnesium-deficient. Deficits appear to worsen after age 50 in men, and African Americans take in less magnesium than Caucasians do. So we all can benefit from more magnesium.
It has also been established that Alzheimer's patients have much lower levels of magnesium in the body. In fact, the lower the magnesium levels, the worse the Alzheimer's symptoms. It follows, then, that administering magnesium I-threonate, which can cross the blood's brain barrier, to Alzheimer's patients would likely lead to improvements in learning, memory and emotional control.
About Mind-Max
Benefits:
Supports brain function, memory and concentration.
Mind-Max contains magnesium I-threonate plus gotu kola aerial parts, bacopa leaf and ginkgo leaf herbs well-known to benefit circulation and brain health for a powerful brain boost. Between the ages of 20 and 90, the average person loses 5-10% of his/her brain weight, with an accompanying loss in memory, attention and other cognitive functions.
Research shows that a decreased number of nerve synapses (the connections between nerve cells) may be responsible for this cognitive decline. Magnesium plays an essential role in nerve synapses. However, magnesium shortages have become common with the increase in processed foods and the lack of magnesium-rich whole foods in the diet. Moreover, most forms of magnesium are not well-absorbed by nervous tissue. Researchers at MIT have discovered that magnesium l-threonate, a highly absorbable form of magnesium, can easily cross the blood brain barrier and that it increases the brain's magnesium level.
Ingredients:
Magnesium I-threonate, gotu kola aerial parts, bacopa leaf extract and ginkgo leaf.
Recommended Use:
Take 3 capsules before breakfast and 3 capsules before bed. Only nighttime dose is recommended in the first week, add morning dose as tolerated.
