I had a hair analyses test done thinking it probably would come back showing heavy metals (if so my specialist was going to get me to have blood test) .. I rang him today to make appointment in regards to getting test results and he told me it had come back saying I have no moybdenum at all and hence will need to be taking supplements for it. He said moybdenum is essential as its needed to make a couple of enzymes and is important to protect against chemicals. (highly interesting for me to hear seeing I have MCS). ..... Im going to see him Tuesday so will find out more about my test results then. He's said for me to take 1mg per day and suggested supplement called molyzinc. Im wondering if this issue is the norm in those with MCS? and would like to hear from others who's had their moybdenum tested.
