Chelation therapy is an intravenous treatment designed to remove heavy metals from the body in order to treat its toxicity.

Proponents claim that can be considered a remedy for disease of the coronary arteries and other diseases that may be associated with injury induced by free radicals.

If the preparatory examination suggests a situation that can be improved through chelation therapy and there is no health reason for which it can not be used, treatment can be initiated. The patient is usually in a comfortable area, sometimes in a group, and an intravenous line is placed. A solution with EDTA is administered together with vitamins and minerals adapted to each patient.

Most treatments last between three and four hours, during which the infusion must be administered slowly to be safe. The number of recommended treatments is between 20 and 40, and they are administered between one and three times a week.

Maintenance treatments can be started at a rate once or twice a month. Chelation therapy benefits occur approximately after three months of treatment. Intravenous vitamin C and mercury chelation therapy may also be associated.

Below we will detail the pros and cons of chelation in a way that allows us to make a decision whether or not to use it according to the state of health of our body.


If a person wants to undergo chelation therapy, a complete clinical history and a physical examination must first be obtained to define the type and extent of the clinical problem. Laboratory tests must be performed to determine if there is any disorder that may contraindicate the use of chelation.

Patients with previous hypocalcemia, poor liver or kidney function, congestive heart failure, hypoglycaemia , coagulation problems, tuberculosis or allergic disorders are at increased risk of complications due to chelation therapy. A Doppler ultrasound can be performed to determine the adequacy of blood flow in different areas of the body.

The pros of chelation

The benefits of chelation with EDTA (diaminotetraacetic acid) for the treatment of lead poisoning and excessively high levels of calcium are not discussed.

Chelation therapy cost is not much high and everyone can afford it easily.

However, indications of benefits for people suffering from atherosclerosis , disease of the coronary arteries and other degenerative diseases are more difficult to prove.

Described uses of chelation therapy for the treatment of angina pectoris, the gangrene , the arthritis , multiple sclerosis, the disease Parkinson, psoriasis and Alzheimer ‘s disease.

On the other hand, people who experienced a decrease in vision, hearing, smell , coordination and sexual potency have improved after undergoing chelation therapy.


It is important for people receiving chelation therapy to work with experienced medical personnel.

It should not be carried out without a good physical evaluation, lifestyle, history and laboratory tests. The staff must have the results of the tests and answer any questions that the patient may have.

The evaluation of the treatment should be individualized and include an assessment of renal function before each treatment with chelation, since the metals captured by EDTA are excreted through the kidneys.

Although EDTA binds to toxic and harmful metals, such as mercury, lead and cadmium, it can also be associated with some essential nutrients in the body, such as copper, iron, calcium, zinc and magnesium. During chelation, large amounts of zinc are lost.

The deficiency of this element can alter the immune function and cause other detrimental effects. Zinc supplements are usually administered to patients undergoing chelation, but it is not known if this is adequate to avoid their deficiency. In addition, chelation therapy does not replace adequate nutrition, exercise, and medications or surgery indicated for specific diseases.
