No, not exactly the same thing, but Modifylan does contain sodium alginates which is essentially Algin. I'm sure they include alginates to buffer the effects of the chelators which are in the product.

My personal opinion is that it's really expensive for what you get. I will predict that you will see many more pricey "heavy metal detox" type products come on the market in the upcoming years because of the growing awareness of heavy metal toxicity. There is always a sector of the market that feels more comfortable paying for higher-priced supplements and the vendors will happily supply.

There are many opinions about this topic and mine is summed up in this: slow, gentle, methodical, natural, inexpensive. I am fortunately a detox success story and this worked very well for me.

Hope this helps!
