I currently take GreenEnergy Chlorella 500mgs. each capsule.I have read other posts on the board about people having stomach problems or assimilation of nutrients(sounds like StarTrek Borg). Concerning this you could possibly muscle test strong for the supplement (good for your body) but your stomach and intestines can't process and absorb it. This could have Very bad consequences of deficient body and bad bacteria and fungus's (fungii)or (FunGuy) having rule over the body by multiplying out of control. My wife and I have had many discussions about these topics and our conclusion is that many of these problems are originally caused by mercury poisoning. That seems to be the foundational cause and because of it being a neurotoxin, it damages so many systems that it's hard to pinpoint any exact cause.
