How much dao is actually in it? though the title says dao, the ingredient list doesn't actually list dao but other vegetables, etc

This one has 1,000,000 HDUs in each tablet. That is the proper way to measure DAO for this purpose. An HDU is a histamine digesting unit. The ingredients list tells you what the product is made from. Check out the manufacturer’s website. Some DAO is from animal products. This one is not and I find it much more effective. I often take less than 1 tablet. I cut them into fourths and take one or more fourths depending upon how I may react to particular foods. Takes a little trial and error, but worth the effort to figure out so that I’m not taking more than I need.

Does this product contain sulfur/sulfites or any derivative of in any of the inactive ingredients? As well, is there any polyethylene glycol?

The product does not contain any of them. The product only contains what is labeled.

I noticed these are individually packaged. If I divide a pill over several days, will exposure to the air cause make them less effective?

Do not break these pills. They are coated so that they pass through the stomach and go into the intestines before they open up. If you break them, they dissolve in the stomach acid and will not be as effective against histamine. You could, I suppose, grind them up and put a portion of the powder into a "delayed release" capsule. That would work, but what a pain. Just take the whole thing, having too much will not hurt you. This company also makes a 3,000,000 HDU version and it is in delayed release capsules. I take those.

where is this manufactured ? Thanks

It says Spain. Europe is ahead of us on MCAS and mastocystosis. This works…not a panacea but very helpful.
