One more comment about DermaMag and magnesium chloride. One of the people posting a comment in this thread said that they wouldn't "go near" magnesium chloride because chlorine causes health problems. Of course, magnesium chloride has nothing to do with chlorine. Chloride a the type of magnesium molecule. In similar fashion, Sodium chloride, or common table salt, is a chloride molecule, but also has nothing to do with chlorine.
Chlorine may cause Tics, but magnesium chloride, a perfectly safe, very healthy supplement, most certainly does not.
Thanks.
