In addition to providing magnesium, magnesium malate also supplies malic acid. Malic acid is found in fruits such as apples, and is also produced in the human body. Malic acid is a metabolite of the Krebs cycle - the metabolic process used to produce 90% of all energy in the cells of the body.
Malic acid readily crosses the Blood-Brain-Barrier (BBB) and has been shown to bind to aluminum. In the brain, aluminum breaks down the structure of neurons, causing them to starve by displacing magnesium from tubulin, a glycoprotein responsible for making microtubules. These tiny pipe-like structures within a neuron provide needed rigidity. They also transport neurotransmitters and nutrients from the nucleus to the far ends of the cell. A chronically low intake of magnesium has been associated with increased levels of toxic aluminum deposits that destroy the microtubules and the cell. Magnesium malate is an excellent chelator that makes magnesium available to neurons.
Malic Acid's unique ability to bind with aluminum means it can be flushed out of the body, preventing unwanted build-up. Magnesium malate is a good source of magnesium and would be your best choice in depleting unwanted aluminum build-up in the body.
