EDTA Chelation

I appreciate your recent article on EDTA Chelation therapy.

I have diffuse vascular calcification on CT and x-ray and am interested in therapy for this.

My question is, how can Calcium EDTA remove calcium from your vessels? It would seem the calcium liberated from the calcium-EDTA that’s absorbed or administered IV would be greater than any calcium removed from arteries.

Is calcium EDTA used in IV chelation therapy?

Thank you.

Dear Randy,

You ask a very good question. I’ve been a proponent of chelation therapy for over 30 years. Sodium EDTA (Na-EDTA) has been the mainstay of intravenous chelation therapy, but has been augmented in recent years by calcium EDTA (Ca-EDTA). Na-EDTA can be slightly irritating to the veins, and must be administered more slowly (usually, about 3 hours per treatment) versus Ca-EDTA which can be administered rapidly or even via IV push.

I believed, like you, that Ca-EDTA would be less effective than Na-EDTA in removing calcium, although it was purported to be more effective in removing other heavy metals.

However, a recent study conducted in Germany compared the efficacy of Na-EDTA versus Ca-EDTA in removal of heavy metals. Data from 600 patients over a ten-year period were analyzed for toxic and essential mineral removal using both Na-EDTA and Ca-EDTA. The results showed that Na-EDTA and Ca-EDTA were equally effective in removing lead from the body, while Ca-EDTA was more effective in chelating aluminum (see Table 1). Although the Ca-EDTA appeared to be even more effective than Na-EDTA in removing calcium, as you surmised, part of that calcium might have been from the CaEDTA itself.

Nevertheless, based on my clinical experience with both forms of EDTA, I believe that the clinical efficacy of both forms of EDTA is about the same.
