Malate

Magnesium malate is formed when an ion of magnesium is attached to a molecule of malic acid (an organic compound found in fruits and vegetables, especially apples).

And, here's 5 surprising benefits to using magnesium malate:

1. Magnesium malate has the ability to bind to toxic metals, like aluminum, and render them ineffective.
2. Magnesium malate is good for your skin, it helps exfoliate and give skin a youthful appearance.
3. Because of the malic acid, magnesium malate plays a vital role in supporting overall muscle performance.
4. Magnesium malate promotes the production of saliva, which helps control oral bacteria.
5. The malic acid in magnesium malate plays a central role in the energy production cycle and is particularly important for healthy energy levels.

It's important to be sure you are choosing a good form of magnesium, like magnesium malate. Other cheaper forms such as magnesium oxide are poorly absorbed in the body.
