An anxiety sufferer, my studies suggested magnesium as a possible aid. Studies show most of us are deficient in this mineral. Chelation may be the best way to make magnesium absorbable. CR really seems to be on to a good idea in chelating magnesium to another calming amino acid, taurine. My MD noted my blood pressure was normal where it was typically high. I asked why he thought it had dropped. He said "it's the magnesium". It really surprised me that an allopathic doctor would make that connection. I thought I'd only hear such from a Naturopath. I suggested to my father-in-law that he ask his doctor if he could wean off of blood pressure medicine and give magnesium a chance. He was unwilling. Imagine, giving your body something it actually needs instead of a drug.
