Erythritol is supposed to be BM neutral and have no GI effects because the gut bacteria can't digest it — my experience would match with that. Other sugar alcohols, though… 😂😂😂
I'm very pale so even in winter I should be getting reasonable amounts of vitamin D — I noticed no difference health-wise when I was supplementing. In fact supplementing turned out to be a bad idea for me in some ways — I had to stop the B vits suddenly, and my entire face broke out in this bizarre rash that was like a million pearl zits (the ones with the little hard white nugget inside). My facial skin has never been the same since 😂
I prefer sucralose or a sucralose-erythritol mix to stevia — for some reason, stevia has a delayed effect for me, so I'll take a sip of tea and it tastes completely unsweetened for a second, before the stevia hits. Weird.
Funny thing about me and vitamin D, I hardly go outside, and my building live in has a single window with heavy wooden blinds I never open. I hardly have a chance to produce it naturally.
I hear you on the sugars, I once thought my excessive erythritol intake was my reason for my loose stools and cut out all sugar alcohols for a 7 day savory cleanse then after went 2 weeks using stevia and monk fruit instead. Had no effect on my BMs. I spike glucose to any carbs or sugars so I do not eat them, >.> I just make Keto friendly cookies, cakes, etc. over 5 days a week. >.< Baking is my side income, stress relief, and a fun hobby.
I imagine, here in America, our crops are grown in in ways they do not contain the amounts of vitamins they should, our processed gluten foods are sprayed with multivitamins, and our gluten-free food lacks said enrichment making celiacs attempted the SAD (Standard American Diet) even worse off. The supplement industry is big here because many have issues and deficiencies and people are just supplementing instead of eating right or trying to fix their hole filled bucket guts by taking as much as they can.
My understanding is not this. My understanding is that the antibodies are there, under the skin and iodine can aggravate the antibodies. The antibodies sit there under the skin, sort of like dormant plants in winter, if iodine intake is high enough (depending on the individual & the # of antibodies remaining under the skin) then it "triggers" the rash to flare.
