I recently did my first round of frequent dose chelation with modified citrus pectin in addition to the usual DMSA/ALA combo. What inspired me was this mans comment in this video: Fighting Cancer Metastasis & Heavy Metal Toxicities with Modified Citrus Pectin- Isaac Eliaz. I dosed with 100mg of DMSA and <100mg of ALA as I did on the previous 2 rounds but I added 3g of MCP and took it according to the half life(5-6 hours) every 5 hours. It meant I was up more throughout the night which is why I stopped after 3 nights instead of continuing to day 4 as I did the last couple of times. In the end I did the last dose around the 88 hour mark. I really wanted to do a fourth day to test the mans claim because I remember feeling the effect of chelation(tired to say the least) on the day 4 and maybe day 3 last time. The time before that was a hard round, I'm not sure why, maybe I didn't take enough zinc and anti-oxidants throughout. It might be too early to say but I think MCP does help you avoid side effects. Next I'm finishing what DMSA I have left then I'm going to chelate with MCP alone and maybe add ALA. MCPs half life makes it idea for mopping up what ALA modilises, leaving enough of the chelator in the system the day after to prevent redistribution. Appearently its better for your immune system than medicinal mushrooms so if that reduces cytocines while chelating its probably another reason for reduced side effects. The other being than it bond strongly to metals, stronger than DMSA which I've heard drops-picks-up-drops-picks-up ect. It chelates several nasty metals and doesn't touch the good ones. It doesn't cause cytotoxicity either. If your chelating, why not give it a try and tell me how you find it.
