Yes. Algin is particularly beneficial for absorbing heavy metal contaminants (i.e. mercury, lead, etc.). It will help whether you have mercury from amalgam fillings or from other environmental sources.

If you're feeling healthy and want to detoxify a little more aggressively, you might consider trying a product like Heavy Metal Detox, which contains cilantro, N-Acetyl-cysteine and Alpha lipoic acid to pull mercury out that has been stored within the body tissues. There's also Enviro-Detox, which is a more general detoxifying formula that helps cleanse and strengthen all the detoxifying systems of the body. (I would recommend doing one first, then the other, but not both at the same time. I would also suggest taking extra Algin, especially with the Heavy Metal Detox since it will be pulling mercury out of the tissues...you want to make sure it gets absorbed and eliminated from the body and not re-absorbed back into the bloodstream.)
