Mcad is thought to play a role in chronic diseases such as me and pots. Here is an interesting article I found. It has something to do with the calcium pathway: http://www.ncbi.nlm.nih.gov/pubmed/21713652 I Think it could help with allergic/anaphylactic conditions in mcad as well. The latest research into asthma has a calcium link. Some of you may know asthma is thought to be a mcad as well. I will post that link too after this one.
