Interesting fact: Algin is stockpiled by the government for protection against nuclear radiation exposure (war, etc.).

Even if I didn't notice a difference with Algin, I would still take it knowing it's properties in relation to mercury AND knowing that it provides other benefits as well, particularly related to the digestive system, which is particularly important when mercury toxic.

The real difference I see with Algin is when eating something with mercury in it. If I eat salmon without Algin, I will have several symptoms appear within 1 hour. With algin, I get either no symptoms at all or almost unnoticeable symptoms. It makes all the difference in the world.
