I haven't had luck finding supporting evidence on this, but I have very sensitized skin and am prone to facial redness /flushing and I've long known that calcium from dairy makes it worse. I always assumed it was some vitamin or mineral in the milk that caused the redness like vitamin A, which on its own as a supplement has the same result for me, but lately I've just been getting calcium from calcium carbonate powder and it's the same thing. My face is very red and irritated when I take it.
Does this indicate something? I've never heard of a Calcium allergy and I don't show symptoms anywhere else on my body. But it's annoying and keeps me from getting 1k mg or so of calcium daily. If I take a small amount like 300mg then the redness is more manageable.
