You should find a practioner who does the Electrodermal Screen that can verify if a particular cilantro or chlorella is good for you. If some chlorella contains some mercury, it can be bad for you. I was trying to follow Dr Huggins protocol for detox...25mg DMSA 3x a week...but nothing else was recommended. I was hitting and missing with good chlorella and other supplements..but I am convinced you need to follow a good practioner who has had good results with detoxification of mercury. I found one at livinglonger.com who use the avatar electrodermal screen test for heavy metals. They have a product called chelex that contains EDTA, chlorella, cilantro, alpha lipoic acid and other herbs. I have felt better with this detox plan. You should find a practioner in your country that has been recommended to you.
