I read it really bothers some in here and makes them go over the edge as far as symptoms go, also Andy Cutler says stear clear of it. I used it before my tooth was out for a week and afterwards for years and it made me feel better or kept me healthy, never had one bad reaction to it. Makes me wonder why so many can tolerate things and others can't, very tricky stuff this Mercury is. If I had no side effects at all from it and felt better at times does that mean it did not mess me up worse by stirring up Mercury? Either that or I am in the state I am in now because it stirred it up for years and made me worse? I hope I have not done permanent damage from my tryings with it and Cilantro (I used it for a week or two last winter but quit so I don't think much damage happened). I know some say these things stir up Mercury and withough Algin or something to soak it up and take it out then it can redistribute and hurt you worse, but it never made me feel any worse and infact keep my blood sugar normal. I was told or lead to believe back then Chlorella took it out of the body, but now I don't see that as the case and was misinformed.
