Of course. I've tried most things on the planet that don't cost 10 grand. :P
I was juicing up to 3-4litres a day of organic juice for months, trying to do Gerson style. All it did was make me lose weight, no help for the condition.
As for lecithin - not sure why but makes me sick & gives liver pain, as most anything does that is supposed to help the liver in normal people. More I take it, worse I get. Dandelion and milk thistle, in fact all herbs are full of salicylates and make all problems worse (asthma, skin outbreaks, muslce pain) - they act as a poison, so no herbal treatments for me.
Cayenne is very high in Salicylates and has the same effect as the other herbs, instant itchy asthma and muscle pain.
Now that is an idea - ascorbic acid with baking soda! That may help the acid effect. As someone mentioned above ascorbic acid being the best form.. I wonder if it stays the best form once the bicarb is added?
Bentonite - I have a pure one and it's good, however taking it orally makes me feel much more toxic. I think these things are to do with having one of the worst leaky guts in history.
I have plenty of magnesium from one form or another at any time.
Not sure re: minerals. Had mixed mineral formulas before, dont feel any effect even after bottles.
