Is there a reason why a supplement would be ok to use in pregnancy but not while breastfeeding? I'm specifically wondering about the use of SAM-e and can't find any real information aside from LactMed saying that it should be ok post-2 months. I find it curious since there have been studies showing the use of SAM-e to be safe in the third trimester but no studies in breastfeeding women. It would seem logical that if it is ok for baby in the womb, it would be ok once born. Is my logic faulty? Are there instances in which something is safe during pregnancy but not safe during breastfeeding?
