Don't know if this will help but at my local health food store I asked about Algin. They had not heard of it so I asked about sodium alginate and told them it comes from brown seaweed. We pulled the book out and looked it up and it said that it helped in the detox of heavy metals,(mercury, lead, strontium-90, barium, cadmium, manganese, tin, zinc, and various radioactive materials)and also environmental pollutants and toxins. Hope this helps.
