Algin

Hi, I have heavy metal poisoning..mostly mercury and lead. I have done chelation before in the past but now I want to go the natural route and use cilantro and chlorella to chelate. but I've read cilantro taken without Algin may cause reabsorption so I will buy some Algin. My question is when do I take the Algin? because I have heard that Algin absorbs nutrients/supplements as well so taking it with cilantro or chlorella may be pointless because it will make it less effective. If anyone can help that would be great. Thanks
