I use Oxypowder too. The magnesium is not absorbed by the body but used as a matrix to which nascent oxygen can be bound. So you are not flooding the body with magnesium, but rather introduce oxygen in the small and large intestines. This will
turn the compacted fecal matter into a liquid or a gas and potentially will get the oxygen into other bodycells too (after intestines are clean). Magnesium laxatives draw moisture from the body but not the oxygen products. Read info on Oxypowder .com">http://www. Oxypowder .com
As far as allergies you should read the messages on the liverflush forum. Most people get rid off allergies by flushing, I did too. I started out that way and later when I found oxypowder I added that too.
Liverflushing gets also parasites out.The only way to unclog the liver is by flushing but not by oxypowder.
