Magnesium contributes, amongst other things, to a reduced fatigue and exhaustion, normal energy metabolism, a normal functioning nervous system, normal muscle function and normal psychological function (1).
Magtech ™ from Natural Stacks is a high quality mixture of all three types of magnesium known to have the highest absorption: Magtein ™ magnesium L-threonate, magnesium taurate and magnesium glycinate. Each compound is fully chelated for optimal absorption and effect. "Chelated" means that the magnesium is bound to an amino acid.
Chelation is the body's natural way to transport minerals across the intestinal wall as part of digestion, so chelated magnesium is absorbed much better than most other magnesium supplements consisting of cheap magnesium salts. The manufacturer has chosen forms of magnesium that are chelated with nutritionally functional amino acids, each with a specific role to optimize mental and physical performance.
Magnesium for improved memory and sleep
Increased levels of magnesium in the brain have been shown to improve cognition and memory, and promote relaxation and improved sleep quality. Research suggests that the compounds of Magtech can deliver more magnesium to the brain than other forms of magnesium.
Studies have shown that magnesium L-threonate contributes to an increased level of magnesium in the brain, which has been seen to reinforce learning and memory (2) (3). Researchers have found that taurine (which is also found naturally in meat), found in magnesium Taurat, increases decision-making abilities and mitigates the effect of caffeine-withdrawal symptoms (4). Taurine has been shown to have neuroprotective properties (5). Taurine supplementation can also relieve visual fatigue caused by working infron of a screen (6).
Another study in healthy male volunteers found that glycine, found in magnesium glycinate, reduces daytime sleepiness and fatigue that comes from acute sleep restriction (7). A study of people with continuous sleep problems concluded that glycine intake significantly improved fatigue (8). When researchers studied the effects of glycine intake before bedtime on volunteers with unsatisfactory sleep, researchers found that it improved the subjects' own satisfaction with their sleep, and sleep efficiency and reduced difficulty falling asleep (9).
