EDTA is a synthetic amino acid and chelating agent that binds to metal ions, forming stable complexes. This binding process alters the metal’s reactivity and allows for removal. It is commonly used by health professionals in chelation therapy to target unwanted heavy metals like lead, cadmium, arsenic, and mercury in the body.

Why Calcium Disodium EDTA?

Calcium disodium EDTA is the preferred form due to its selective chelation of toxic heavy metals while sparing essential minerals, and because of its established safety and common use by health professionals.

How does EDTA work as a chelating agent?

EDTA binds to metal ions, surrounding them in a stable structure. This process alters their chemical reactivity and allows for their removal.

What metals do EDTA (calcium disodium EDTA) bind to?

It can bind to a wide range of metals but binds most aggressively with lead, mercury, aluminum, and cadmium.

How should I take EDTA for maximum efficacy?

For best results, take EDTA on an empty stomach. This prevents EDTA from binding to minerals in food and ensures optimal interaction with unwanted metals.

Does calcium disodium EDTA remove calcium from the body?

Calcium disodium EDTA does not aggressively bind to calcium. It is pre-bound to calcium, making it selective for other metal ions.

Does calcium disodium EDTA pass the blood-brain barrier?

No, calcium disodium EDTA does not significantly cross the blood-brain barrier.

Can I take EDTA continuously, or should I cycle on and off?

It is recommended to cycle EDTA usage, such as 6 weeks on and 2 weeks off, to maintain a healthy balance of essential minerals.

Do I need to take a multi-mineral supplement while taking EDTA?
