Featuring Magtein® – Shown To Reduce Brain Age By 9 Years

Magnesium in the brain is important for synapses, cognitive function, energy production, and plasticity. Yet normal magnesium doesn’t usually cross the blood-brain barrier. Magtein® is a specialized, potent form of magnesium-l-threonate developed by MIT scientists. It’s designed to solve this problem. The Magtein® inside MagTech™ is built on more than a decade of research from MIT, led by the original inventor Dr. Liu. During the official 2015 placebo-controlled clinical trials, the results showed a meaningful increase of memory-related functions in the brain which represented a 9-year age improvement when subjects supplemented Magtein®. 


MagTech™ is a magnesium complex that combines the 3 most bioavailable forms of magnesium in their science-proven doses to provide you the most potent benefits from this super mineral. It enhances brain function, aids relaxation and improves sleep quality.


The supplement facts panels of dietary supplements state the amount of elemental magnesium in the product, not the weight of the entire magnesium compound. There are many different types of magnesium compounds. Each compound provides a different amount of elemental magnesium and varies in bio-availability (ability to be absorbed by the body). Bio-availability is most important thing to consider when evaluating the effectiveness of a dietary supplement. For example, Magnesium Oxide is the most dense magnesium compound available. It contains 300 mg of elemental magnesium per 500 mg of material, but its bio-availability is extremely poor. Studies have shown that only about 4-13% of its elemental magnesium is actually absorbed by the body. Natural Stacks MagTech contains the three magnesium compounds that are known to have the highest absorbtion; Magnesium L-Threonate, Magnesium Taurate, and Magnesium Glycinate. These compounds are not as dense as other forms of magnesium(less elemental magnesium by weight) but they are significantly more bio-available.


Side effects are uncommon when supplementing magnesium at the standard dosage level. In some people, exceeding doses of 350mg might cause stomach upset, nausea, vomiting, or diarrhea.
