Magnesium is only as good as your body's ability to absorb it. Don't shortchange yourself by choosing inferior forms of magnesium supplements. Opt for magnesium citrate, one of the most bioavailable forms of this important mineral to date. When it's bound to an organic compound like citric acid, your body will recognize it as food and absorb it as such. Hundreds of cellular processes in the body depend on magnesium, and the more magnesium in your bloodstream, the more available it is to your cells. No yeast, wheat, soy, gluten, milk, salt, sugar, starch, preservatives or artificial color.
