I just asked Laura (she does most of our research) and she said that she has found a connection with Strontium-90 and (if she remembers correctly) lead and she does not remember if she found research directly connecting Algin with heavy metals or not.

She may get some time to do a search tonight through her medial research archives/subscriptions and see.

Of course, the Laura and I both have had remarkable results with it pertaining to mercury and we find that about 6 of 10 people that try it do as well. (3 of 10 have marginal results and 1 of 10 get stomach irritation).

Perhaps she'll have some time and see if she can find more information for this thread.
