Sorry I took so long to get back to you. I just noticed your message. I saw it advertized in mail order catalog and it said how it helped people of chernobyl to get better than expected results in their use of it and that it was used for heavy metal chelation also. I already knew seaweed was good so I thought this may work even better so I did some research on it and then decided to order it. I'm so glad I did. It helped me get rid of nickel and cadmium heavy metals, so I'm convinced this is one of the best detoxifiers I have ever come across in my 25 years of health research and experimenting.
