Recently, I've been using hair analysis of the mother. Those levels are still not accurate, but they are much closer, and a fairly high level is a better indicator that the autistic child in most cases..
Why use ascorbic acid Vitamin C? It's relatively cheap; It's very safe to use even in very high doses, most chelators are expensive, and Glutathione is difficult to get into the bloodstream for any amount of time. It should be noted here that "ascorbate" forms of vitamin do NOT take out any minerals, as they are already in the ascorbate form. Only the plain ascorbic acid combines with minerals in the blood to form an ascorbate there which is then filtered out by the kidneys and exits the body. (A common "joke" is that if the vitamin C has my name (Bate) in it, it's no good for taking out minerals. Read the label.
In my former practice (80's & 90's) I helped many schizophrenics cure themselves using only ascorbic acid vitamin C. For adults, I usually went up to 10,000 mg (10 grams) per day in split doses. They were on this amount for perhaps a year, but after a week or so, they usually become free of the major symptoms. The vitamin C "neutralizes the toxic action of minerals as well as taking it out of the body!
The amount in the RDA is ridiculous at best. 75 mg - Bah humbug! Talk to a zoo vet and you'll find that the RDA for a 150 pound ape is 4000 mg per day. Humans and apes are exactly alike in basic metabolism and vitamin C need. I've been taking 4000 mg for many years, and I do not get infections from bacteria or viruses.
The other good thing about ascorbic acid vitamin C is that you can't get into harm using it. Take too much, and you only get diarrhea. Even in infants and small children. For infants under 20 pounds, I'd use 250 mg twice a day.
There are several chelation materials used today. Chelate means to "grab onto". The MD "standard" is EDTA. This chemical is put in intravenously. It's expensive in "doctor" time. Zeolite is another that can be used at home, but it's also much more expensive than plain old Ascorbate Acid (vitamin C).
Excess copper, particularly in women on the "pill" may cause schizophrenia, mercury is a cause of depression. Mercury and aluminum both cause brain cell death. In order to really cure such, these toxic minerals MUST be taken out of the body.
