Thanks Laura. Since the dose is just below 1 gram of Algin for 2 capsules, that adds less than 0.1 microgams of mercury per recommended daily dose. That is roughly what one would get from 1 gram of cod, or over 200 times less than mercury from a decent cod meal, say 1/2 pound. Swordfish would have ten times more than cod.

Although it would be nice if they could extract even what little it has and claim mercury-free (considering that people with mercury toxicity would be likely customers), from the claimed figure it seems fairly safe. How much Algin would someone detoxing from amalgams normally use?
