Could magnesium supplements treat anxiety?

Magnesium can be. Used to help w/anxiety but it is far better to seek out the help of a professional also. There are many causes for anxiety and it's best to get trained in strategies to resolve them. Also, too much magnesium can cause the runs and there are several types of magnesium. I use magnesium citrate w/patients. You may also find a brand called jigsaw magnesium helpful. Peace and good health.
