Pure MAG Concentrate

ShopFreeMart PureMag Concentrate™ is a new chelated form of magnesium that was developed by a team of neuroscientists at Massachusetts Institute of Technology and Tsinghua University in Beijing who bound magnesium to l-threonate, a vitamin C metabolite.

Magnesium the Master Mineral

Magnesium has been called the Master Mineral because it is essential to life, found in every living cell and is required for every physiological process that goes on in our bodies. It is as necessary to life as oxygen and water. When you run out of magnesium, your heart goes into spasm (heart attack) and you die. Within the last fifty years, research indicates that approximately eight million people have died from heart failure, due to a lack of magnesium alone.

Magnesium helps form bones, protein and fatty acids. Essential for energy production, insulin secretion and heart function.

Magnesium works in partnership with calcium and boron in many physiological functions including nervous and cardiovascular processes and bone-building.

Magnesium plays a vital role in the contraction and relaxation of muscles, including skeletal muscles, as well as those of the gastrointestinal tract, and muscles regulating blood flow, blood pressure and breathing passages.

Mental and emotional functions require adequate magnesium for neurotransmitter and hormone production. Magnesium is also essential for making new cells, activating B vitamins, clotting blood and secretion of insulin.

Magnesium is essential for the production and utilization of ATP (our energy currency) and perhaps the two biggest symptoms of Magnesium deficiency are fatigue and weakness.


Bone Weakness

Hypertension / High blood pressure






Joint and muscle inflammation, pain and stiffness

Muscle weakness, cramps and twitches



Poor Circulation

Sleep Disorders

What is Magnesium L-Threonate?

It is a chelated form of magnesium that was developed by a team of neuroscientists at Massachusetts Institute of Technology and Tsinghua University in Beijing who bound magnesium to l-threonate, a vitamin C metabolite. (1)

Chelated simply means that the magnesium molecules are bonded to another molecule. Chelation can improve a magnesium supplement’s stability, absorption, and bioavailability. (2)

Magnesium sulphate is a form of magnesium that naturally occurs in Epsom salts, but the body can absorb very little of this form of magnesium without hydrochloric acid being taken in conjunction with it. And since it can’t be readily absorbed, the body must get rid of it and thus it acts as a harsh laxative in the bowel. Magnesium sulphate is one of the worst forms of magnesium that you can take, especially if improving brain function is your goal. (3)

Frustratingly, very little of the magnesium found in typical supplements gets into the brain, limiting its therapeutic value. (4)

How Does Magnesium L-Threonate Work?

Magnesium is largely missing from the modern diet due to current farming practices. More than half of the industrialized world is magnesium-deficient. In the US, it is estimated that only 32% of the population get the RDA (recommended daily allowance) of magnesium.

The need for magnesium in the brain is high. It is found in higher concentrations in the brain than in the blood. It plays a critical role in a number of brain-related and neurological conditions including depression, anxiety, ADHD, bipolar disorder, schizophrenia, addictions, acute brain injury, seizures, Parkinson’s disease, and Alzheimer’s disease. (6, 7, 8, 9, 10, 11)

Magnesium l-threonate was specifically created to cross the brain’s protective filter, the blood-brain barrier. (12)

Another brain enhancing property of magnesium l-threonate is that it increases brain plasticity. (13)

Plasticity is the brain’s ability to change and grow, and is fundamental for memory and learning to take place.

Lastly, there’s evidence that magnesium l-threonate can increase brain-derived neurotropic factor (BDNF), a protein that stimulates the formation of new brain cells.
