hi
have you heard of ndf. this is supposed to be a very good mercury chelator. it consists of cilantro and chlorella and is supposed to be more effective than dmsa and a lot more gentle on the body. it is pricy but if it works and does not make you sicker then its got to be worth it. have a look on the internet, it does sound very promising. for the more sensitive person there is a product called ndf plus which is much gentler but still effective.
