Just tried this again yesterday, unfortunately it didn't go well. If anything it seemed to exacerbate my reactions to food, bizarrely.
MCAS is weird.
i noticed i reacted to anything herbal-extracted. pure synthetic forms of many things often do work better for me.
so synthetic vC much better than any plant extracts. that goes for everything even quercetin extract. didnt find a pure synthetic version for quercetin yet.
i also noticed i react to the same supplement-type sometimes positive or bad depending on the vendor.
reagarding the vitamin D, did you try vegan or the sheep lanolin? lanolin allergy isnt that rare. on the other side the vegan one is made from lichen which is a fungus.
i have had a course of vitamin D high dose like 30-40k a week over the last 6 month. i feel my asthma and allergy problematic got worse in that time frame. i already take the lichen form. it did not much for me, raise D from 4ng/ml to 11ng/ml after 700.000 iu. thats a bit , but still danger zone. i dont know if i should continue, i feel like the first days after taking D are the worst.
i do have a question, for magnesium / potassium , what forms are tolerable for histamin problematic? i've read that citrats might be not good?
