Yes, just for fun (not) I looked up a typical supplement / diet page for pregnancy, thought about linking it, but couldnt, as it made me ITCH just reading some of it.
It is the same recommendations I got 17 years ago; calcium, vit D, iron, folic acid. Luckily I was a difficult "patient".
Very few mention iodine
-or magnesium (prevents preclampsia /eclampsia)
-or vit B(for digestion, prevents heart burn, needed for uptake of minerals)
-or zinc (prevents stretch marks; yes it is a deficiency)
- childbearing women are warned against taking more than 500 mg of vit c daily, as it can make the child "dependent" on it, or something..
also we are warned against to much salt (the amnotic fluid is almost as saline as sea water)
-yes here we have the Iodine protocol, more or less...
