Minerals are important for many reasons.
Some also affect the nervous system.
Magnesium is one of those minerals and it affects hundreds of enzymatic reactions as well.
One thing to keep in mind is that the most common blood test for magnesium is not a reliable way to find out if you may benefit from additional magnesium.
Even if blood magnesium levels are within the normal range, you may not have adequate intracellular levels of magnesium.
Another mineral which also may affect your mood is zinc.
There is some research indicating that zinc may be helpful in the treatment of depression (Lai J, et al. 2012).
Minerals are best taken in a combination, because when taken separately they may lower the level of another mineral.
It is also important to take minerals in a bioavailable form to be sure they are absorbed well, and that they are not causing gastrointestinal irritation.
Amino acid chelates are a well absorbed form of minerals and are also well tolerated.
