I agree with most of what you said Sunshine but algin could be useful if taken with meals that would contain methylmercury. Methylmercury can be absorbed in the digestive track, but algin should bind to it. But the stored mercury that is excreted in bile is inorganic mercury and unless you have leaky gut it shouldn't get absorbed in your digestive track either way.

I was always personally concerned with Algin's affinity for zinc and other minerals. Never noticed a benefit from taking it either so I didn't bother continuing, but apparently many people feel a difference. At least its not going to redistribute metals like other supplements.

If anybody can't handle chelating with frequent low doses of ALA/DMSA then I would recommend trying lower doses or using a sauna.
