I don’t know about UV therapy so I can’t pass comment there.
Regarding chelation, I personally would not undertake chelation without filling at least the following criteria:
1) That I was absolutely certain heavy metals were an issue for me.
2) That the person who was treating me was very well experienced and qualified – I wouldn’t let your average run-of-the-mill ND guide me in chelation therapy.
3) That I was in a good place physically and mentally to minimise potential fallout.
4) I had first removed all sources of heavy metals (amalgam fillings, overconsumption of fish etc.)
From what I’ve read, if done properly chelation can be effective and safe. If done improperly, however, you can open yourself up to a world of issues. Do you really trust the person who would be guiding you?
I’m due to have an amalgam filling removed soon, and I have taken the decision that I am not going to do chelation therapy afterwards because I cannot fulfil the above criteria. Instead, I am going to take utmost care in getting the filling removed, and then I am going to support glutathione production in the body. Glutathione is a natural enzyme produced in the body. It is the body’s primary enzyme for detoxing heavy metals. It is supported through supplementation of colostrum or whey (both need to be very high quality), sulphurous vegetables such as spinach, and milk thistle.
From what I have read, mercury has a relatively short half-life in most tissues in the body (60 to 90 days without chelation). The accuracy of this is debated as many would suggest that much of the mercury is tied up and only a DMSA or DMPA would reveal an accurate measure. Again, the accuracy of this is not clear. In the brain the half life can be as much as 17 years. I don’t think mercury is a critical component for me, I just really hate the idea of having a vast source of it anywhere in my body. Moreover, I am still young (aged 22), so if in 17 years I have half the mercury in my brain that I do now: result! I do not know what the half-life of other heavy metals are in the body, and whether this might affect your decision.
If you do not decide to follow chelation therapy, and assuming you are already taking milk thistle and eating sulphurous vegetables, consider adding a high quality whey or colostrum supplement to your protocol. Dr Mercola has more information about this on his website.
