I'm looking for non-sulforous agents for mercury, lead, cadmium and strontium chelation. To my knowledge, the essentials for chelation seem to based around sulfurous agents such as gluathione, NAC, ALA, garlic, EDTA etc which unfortunately are not an option for me On a daily basis, I have been taking 200-300% RDA of selenium in various forms for 7 months, in addition to 1000-5000%RDA vitamin c (as ascorbic acid, which is unavoidable as it's in several of my existing supplements), and 1-2 capsules of grape seed extract (since about a week however I've switched to powder). Four days ago I started taking molybdenum (400% RDA) RDA, but my UAA/UEE two months ago showed high levels of molybdenum (I was taking the same 400%RDA dose of it then) at the time so I'm not sure if it's something I should be doing, but I read it supported the sulfur pathway, so the benefits seemed to outweigh the cons. As neither chlorella nor Andy Cutler's protocol are feasible for me both due to sulfation issues and gastrointestinal ones, @ahmo kindly suggested magentic clay footbaths, chitosan, and a product called Complete Metal Cleanse. I'm wondering if anyone else has had experience with any of these? Chitosan is a fat binder, but I'm a little worried it may bind all the supposedly beneficial fats I take (coconut oil; olive oil; vegan EFAs; although to be fair none of them have stopped my condition from deteriorating). The CMC looks pretty decent, but imposes 6 hour restrictions (3 hours either side of taking it) on taking other supplements, which would be difficult for me as I take 30-40 supplements per day and there are simply not enough hours to fit them all in. I guess I could set my alarm to wake me up 4 hours into my sleep and take it then, but doesn't sleeping hamper the digestive process? The magnetic clay footbaths look like the best option for me, even though they're expensive, and @ahmo says she found them very useful. So, any thoughts? edit: Additionally, does anyone know of any non-sulfurous agents that cross the blood-brain barrier?
