How does Edta work?

EDTA is a chemical that binds and holds on to minerals and metals such as chromium, iron, mercury, copper, aluminum, nickel, zinc, calcium, cobalt, manganese, and magnesium. When they are bound they can't have any effects on the body and they are removed from the body.

Are there safety concerns?

EDTA is safe when used as a prescription medicine and in small amounts as a preservative in foods. EDTA can cause abdominal cramps, nausea, vomiting, diarrhea, headache, low blood pressure, skin problems, and fever.

It is UNSAFE to use more than 3 grams of EDTA per day, or to take it longer than 5 to 7 days. Too much can cause kidney damage, dangerously low calcium levels, and death.

Do not use EDTA in amounts greater than those commonly found in foods if:
  • You are pregnant or breast-feeding.
  • You have heart rhythm problems.
  • You have diabetes.
  • You have low levels of calcium, potassium, or magnesium (known as hypocalcemia, hypokalemia, and hypomagnesemia, respectively).
  • You have liver problems.
  • You have kidney problems.
  • You have epilepsy (seizures).
  • You have tuberculosis (TB).
