In response to your statement regarding humifulvate, at this time there is too little evidense to validate the effectiveness of this product. However the reason I'm writing is regarding your comment on Mercury which is the most toxic substance on earth.
The reason mercury didn't show on your blood test is this:
Whenever you chew, brush your teeth or drink hot drinks you stimulate the release of Methyl mercury which is 100x more toxic than mercury. Now your immune system (white blood cells) will notify the first line of defense which is Globulin part of the total protein. Globulin will snap up the contaminated cell but mercury is indestructable to anything in the body so all that happens is the mercury now has a hiding place and Globulin is rendered totally ineffective.
So a blood test will not show mercury, that is a fact and if anyone tells you differently they are uninformed and simply do not understand or they are telling you lies because they have a hidden agenda.
