My DD, who is healthy anyway, unbeknownst to me was taking an off the shelf multi vitamin pill daily before and during pregnancy to be healthy.
The vit pill included vitamin A.
She and I were not aware that too much vit A can cause pregnancy problems.
There was a warning on the front of the bottle not to take the pills when pregnant or thinking about conceiving, but it was only when I visited her after another miscarriage, that I read the front of the bottle, and saw the warning on it. As with all pill bottles, writing is small and she had not spotted it.
She has now mentioned it to her doctor and the doctor told her not to beat herself up about it, but not to take off the shelf vitamins when pregnant in future because of vit A content.
I just thought I would pass this on.
