Hi there. I'll be honest with you, the problems with cilantro etc, is that not enough is known about them in order to put together a regime that will move/remove mercury in an even safer manner.
But that being said, some people have done ok using them and some have improved, but others have worsened and sad to say, but sometimes it's up to the person whether they want to give those things a go.
But mercury can easily become mobilised and too easily can end up in worse and sensitive areas (brain being one).
This is why many more people are now following the advice and protocol of a biochemist called Andy Cutler, who has had YEARS of study and experience to do with mercury toxicity and how mercury works, and what can happen on risky protocols (he does not advocate NDF, and does not believe it's effective). But as I said, some find it helps them, so ....
andy's protocol, which is one of the safest around that I have heard of (in fact, I don't know one that has this safety to it). Is once a person has had all their amalgams replaced, they can begin to use a chelating agent called "DMSA" or "DMPS" (oral). But you start about 4 days after last amalgam removal and using e.g. DMSA (which is available online, no need for prescription) and you can try about 25 mg to start (or less if this dose is too high) and you take it EVERY FOUR HOURS (around the clock, so you need to wake up at night to take a dose) and do this constantly for about 3 days or up to a week and then stop and have a break for the same amount of time you spent on it. You can take more time off if necessary.
This is repeated for a few months to bring blood/tissue levels of mercury down, before using an antioxidant called alpha lipoic acid. This is used to then chelate the brain and other organs of mercury and again, for safety, needs to be used every 3 hours. Best to use it with DMSA, but you can use it on it's own. Using it around the same way you used DMSA (but just using it a little more often, e.g every 3 hours instead of every 4).
IT crosses the blood brain barrier and can remove mercury fromthe brain, but if you use it too early on with a too high blood/body level of mercury, you risk moving more mercury INTO the brain.
So this is why Andy is very wary of things like chlorella, cilantro, garlic, etc, because though they are natural, they all have an ability to move mercury around and it can be highy risky.
But as I said, there are people who have done ok on NDF etc. But be aware of the moblisation side of things and risks attached to doing that.
Even using DMSA or DMPS, or Alpha lipoic acid can be dangerous if they are not used according to the safer protocol, but anything that is used randomly/erractically, can all do the same thing, move mercury anywhere and everywhere and mercury will readily go into the brain if it's mobilised in an unsafe manner.
sorry for the long post, but just trying to give as much as I can with what I've read. I'm not andy, he would probably tell you to stay away from NDF completely.
But I've tried it myself and others have to. I did get definite problems with it I must admit, but yes it does move mercury, NO DOUBT ABOUT IT. I dont' recall having any long term problems from it though, but I know of some who have. Take it easy whatever you decide to try and monitor your symptoms.
If you are interested in Andy Cutler's protocol and you want to find out more, there is another mercury forum that people who use his protocol go on. The link to it is
