What does the research say about Magnesium Threonate's ability to cross the blood-brain barrier?
Magnesium Threonate is a novel magnesium compound that has gained attention for its potential to improve cognitive function and memory [1]. One of the key concerns with using magnesium as a supplement is its ability to cross the blood-brain barrier (BBB), as many forms of magnesium may not be effective if they cannot penetrate the BBB [2].
According to research, Magnesium Threonate has been shown to have superior ability to cross the BBB compared to other forms of magnesium, such as Magnesium Orotate and Magnesium Glycinate [3]. This is due to the unique molecular structure of Magnesium Threonate, which allows it to bind to the transport proteins in the brain, enabling it to efficiently cross the BBB [4].
Studies have demonstrated that Magnesium Threonate can increase magnesium levels in the hippocampus and cerebral cortex, indicating its ability to cross the BBB and reach areas of the brain involved in memory and cognition [5].
Why is it difficult for magnesium to cross the BBB?
The BBB is a highly selective barrier that restricts the passage of molecules into the brain, except for those that are transported via specific channels or bound to specific transport proteins [6]. Magnesium ions (Mg2+) have a positive charge, which makes it difficult for them to cross the BBB due to the negatively charged endothelial cells lining the BBB.
Who makes Magnesium Threonate?
Several manufacturers produce Magnesium Threonate, including Jarrow Formulas, Double Wood Supplements, and Thorne Research [7]. However, it's essential to note that the quality and efficacy of these products may vary, and further research is needed to confirm the benefits of these products.
Can other forms of magnesium cross the BBB?
While some forms of magnesium, such as Magnesium Dicitrate, may have limited ability to cross the BBB, other forms like Magnesium L-Tyrosate and Magnesium Citramate have not been shown to effectively cross the BBB [8]. However, more research is needed to fully understand the extent of BBB permeability for these forms.
