I know this is an old post but for anyone else reading DO NOT use
Bentonite clay, "natural" chelation like cilantro/chlorella or any of those concoctions that anybody and everybody sells on their website, especially on kids!
Chelating heavy metals is extremely dangerous and you can make yourself worse if you don't know exactly what you're doing, and can permanently disable children.
When you free up heavy metals, if they are not properly excreted by the body they will redistribute, sometimes in the brain or other areas that were worse than what you had before.
To chelate first you have to remove all
Amalgams and metals out of your mouth. Then become an expert on the cutler protocol (very low doses every 4 hours even at night). This is a safe and most importantly PROVEN EFFECTIVE method.
For my kid I found that dosing with vit C, D3, E, and B complex helped dramatically. Also magnesium oil and
Sea Salt /trace minerals in the water.
Filter all water, even bath tub shower head filter. Remove all toxins anywhere you can - soaps, food, flouride free toothpaste - do not use ANY petroleum products like baby oil or lotions. Use ev coconut oil to moisturize and cook with.
Decreasing toxin load and supplementing with vitamins (metals bind to cells and we just can't absorb them from our food) will help. Especially vit C and D3. I was horribly lacking for both.
I take 8 grams, yes I said grams, a day as sodium ascorbate powder and 8000IU D3 a day. Of course I'm probably only absorbing 10% of that which is why it takes so much for me to feel better.
