I have struggled with electro magnetic hypersensitivity for several years (and a few other health problems) all related to mercury poisoning. I tried Super Chlorella for a couple of months, Feb-March 2009 taking in total approx 150 tablets. As a consequence I could no longer use my cell phone or be within several yards of a cell phone without getting problems. The problems which is related to my brain getting foggy and not feeling well. The problem will last for several hours, usually till the next day. I would guess that there are only two logical reasons for this problem. The Super Chlorella must either contain mercury or the mercury in my brain has been moved so that I have become more sensitive to electro magnetic radiation. Before taking Chlorella, I could carry my cell phone in my pocket as well as use it without any problems. Now I cannot go anywhere where there people gathered.
