Ive heard that Modifylan is quite good and that it also detoxes the body of a number of hev. metals, not only mercury. I would be extremely careful with other brands of algae and kelp as MOST THINGS from the sea now days have a very high mercury load and you could actually end up making things worse. Not all products are like this, it depends heaps on the brand. This happened to me wiuth chlorella. I had been taking chlorella for about 6 months and experiencing great results and then switched to a cheaper brand and IT WAS REALLY BAD (increased my mercury symptoms.) back to where I had almost been at the start.
