Dear Cher,
Have no idea if this helps but one of my children broke out in hives from a
vitamin they had taken. As I remember (and the kids are now 23, 21 and 10),
it was a vitamin they had been taking and suddenly developed a sensitivity
to. I don't really remember many of the details. The liklihood is that it
was a healthfood store product.
