Chelation Therapy involves a series of treatments using intravenous administration of a medication call ethylenediaminetetra-acetic acid (EDTA). EDTA does not only remove the dangerous metals but is a powerful antioxidant, a substance that combats free radicals. EDTA improves circulation, makes platelets less sticky, thus reducing abnormal blood clotting, inflammation, calcium accumulation in damaged cells and restores magnesium to the cell.

Chelation therapy works as it did in 1982. What has changed is how the mechanics of chelation are understood. Several studies have shown that chelation therapy works at a cellular level to protect and restore cells to their normal function. Today, chelation may be used on a wide variety of conditions, including vascular disease, Parkinson's Disease, Alzheimer's Disease, macular degeneration, and the aging process. 

The basic process of using magnesium EDTA in an intravenous solution (chelation therapy) given over three hours has not changed for 25 years.

Again, the difference is today's understanding of cellular damage, and how chelation intervenes in this process.

Everyone responds to therapy at a different rate, depending on individual genetic components and personal environmental factors.
