I worked with a MD who was one of the pioneers in orthomolecular medicine (not related to chelation) and he had a very large chelation practice in the northwest. It works. Dr. Castillo does more than just chelation but even just chelation does wonders for pulling out heavy metals, plaque in arteries, etc... EDTA is the chemical and through IV is best. 2nd best is suppository EDTA, that is the next most absorbable place on the body besides the mouth. Supplement tab or cap form of EDTA is NOT worth the money because absorption is poor. Chelate literally comes from the root for the word CLAW as it claws onto stuff.

ACAM is American College for Advancement in Medicine and you this group is conventional MD's who also practice natural medicine. A still relatively rare kind of doctor but becoming more common. Re-directing you to the ACAM Beta Homepage
or search for the docs directly here: ACAM doctor search
Just searched chelation using the code CT and 645 MD's and OD's doing chelation.

This is a very impressive group. You can scroll down the search page and see all the categories those docs are involved in. You can find ones involved with chelation. Can be kinda spendy depending but probably a lot more affordable in Mexico.

However, it is cheap insurance for good health Prevention is key and and ounce of prevention is worth a pound of cure so it of course is worth it.
