Thanks but I am a bit confused now: did you mean chlorophyll or chlorella?
Because chlorella is such a strong chelator ! I tried it once and was so sick with it! I have to say though that my mouth is full of silver fillings and at the time I did not know that chelation and mercury fillings were a "no no ",(not to say dangerous!)
So If wheat grass is not a chelator that would be great to actually feel what it can do to clean blood and remove toxins!
