These essential elements, along with my diet, are what enabled me to go and start doing a course. I could barely function at one point and it was found I was low in iodine and magnesium and selenium and zinc. all of which has been mentioned here. I also added a multi vitamin/mineral powder as well as a foundation.

Anything can lower these elements, not just mercury. Also in New Zealand, we have very low soil content of essential minerals. Might be why we have one of the highest cancer rates in the world....
