Calcium EDTA is already bound to a calcium (hence the name) so it will not exchange the calcium it has for another calcium. But it will exchange it for something else. Di-Sodium EDTA ALSO removes BAD calcium from the body, arteries, capillaries, muscles, joints, brain, and internal organs, preventing heart attacks, strokes, arthritis and a mired of other problems.

Chelation Therapy Explained
The second study of oral Ca EDTA disodium was published in 1954, using a daily dose of 2 grams for 7 days (4). In the symptomatic patients with lead intoxiion, the symptoms improved remarkably following oral EDTA and the blood profile returned to normal.
Sterile pharmaceutical compositions for parenteral administration containing 2,6-diisopropylphenol (propofol) are described for use as anesthetics. The compositions comprise an oil-in-water emulsion of propofol additionally containing a amount of edetate sufficient to
Chelation in Metal Intoxiion - CORE
Lead induced oxidative stress and hematological alterations and their response to coined administration of calcium disodium EDTA with a thiol chelator in rats. (2004). Lead induced oxidative stress and its recovery following co-administration of melatonin or n-acetylcysteine during chelation with succimer in male rats.
Because EDTA4− also binds essential calcium ions, it is often administered as the calcium disodium salt. For example, when Na2Ca(EDTA) is given to a patient, the [Ca(EDTA)]2− ions react with circulating Pb2+ ions and the metal ions are exchanged: [Ca(EDTA)]2−(aq) + Pb2+(aq) ⇌ [Pb(EDTA)]2−(aq) + Ca2+(aq) Kc = 2.5 × 107 A child has a dangerous blood lead level of 120 μg/100 mL.
