Hi Kathy, congrats on doing so much already. So glad the iodine forum helped you! Are you taking iodine and in what form if you don't mind me asking.
You can get the algin on this forum. You can see the adverts for the products on the left side of the forum. But here is the link straight to the algin:
http://onlythebestherbs.com/Products/Algin/It may well help you with symptoms, if you are nervous to try ALA at this stage. Vitamin E, Vitamin C and selenium are good general basic antioxidants that along with the iodine should also help and support you. Magnesium also. When I was very mercury toxic, they helped me a great deal. If you can afford them, get good quality ones - a vitamin C powder with the bioflavanoids and natural vitamin E.
You are 10 months post amalgam removal and you are fine to use ALA if you wish. If you use it according to Andrew Cutler's protocol, you should be fine. Don't forget, you can start on very low doses. The key is to take it frequently (every 3 hours). if you happen to miss a dose or you're very late for one (over an hour late), then you may have to stop the round, wait a few days and start again, rather than risk redistribution.
However, perhaps you could try the algin first and see how things go and you could also take algin whilst you do ALA if you wish to do ALA later on. It may help pick up any mercury that ALA may not get in the digestive tract.
