Histamine issues from food are not always apparent, I have lived for all my life(I am 40 now) and did not realize that I have a genetic DAO deficiency until I took a genetic test. This happens because you don't get symptoms immediately after eating(like in a peanut allergy), histamine usually builds up as the DAO enzyme gets overwhelmed and you won't be able to match symptoms to what you ate past few days. Furthermore histamine could be coming from mast cell activation which is even harder to predict, mast cells can be anywhere and get activated by things like LPS in the gut.normally I'm not sure if I have a histamine problem based on the fact that I can usually eat high histamine foods without issues.
I was thinking at 2 possibilities when I said that:Does vitamin A increase the histamine load?
- allergens in the supplement itself(if it was a cheap one), that would cause histamine to be released directly
- vitamin A helps the immune system: it enhances the antibody response and supports the growth and activation of T and B cells; If you have an infection in the body that creates LPS(this was suggested by your reaction to vitamin D) you will get more LPS from further activation of the immune system, and said LPS will trigger mast cells to release more histamine.
I am very curios to see what reaction you have(if it's any of the above two), so please share.
I have a few thoughts on that:Since even later 10,000 iu of D3 at a time wasn't able to produce anything like the first dose of 5000 iu
1) maybe it's not the same supplement; might be a good idea to try again the same supplement that caused it
2) for whatever reason you don't have as much histamine in your system as you did when you initially tryed it
3) MAO and HNMT enzymes work better now and so eliminate excess histamine faster from your brain
4) the inital dose ramped up the immune system and killed most of the LPS-producing infection, since there isn't that much bacteria now you won't get the same response
DAO enzyme supplements do not work for emergency, it is the same as for Histamine you get from food, it builds up and goes down over several days. DAO enzyme supplements are basically taken during a meal to degrade the histamine you get from that meal, so the body doesn't get additional histamine from what you eat. If you do that for all meals of the day, for several days, the body doesn't get any histamine from food and has time to process histamine that is already in the system. Only then will histamine go down. So as you can tell, this doesn't help in the short term, but only after several days. For short term emergency situations, you can take anti-histamine medication or Quercetin.Can't find anything on that myself. I've been thinking about keeping DAO on hand for emergency immune implosion situations, which one do you recommend?
