I am about to undergo an oral EDTA chelation program to get rid of excess lead that has been discovered after numerous tests. Whilst doing some research, there seems to be a lot of conflicting information on whether EDTA actually chelates b12 or in somes studies it shows that it enhances the absorption of b12. Can anyone shed any light on this rather perplexing issue, before I start. Any info will very much appreciated. Thanking you all in advance.
