Why isn't there any vitamin K in the prenatal formula's?Updated a year ago

Vitamin K has very poor placental transfer which is why vitamin K is given to babies at birth.

Vitamin K1 (phytomenadione) promotes blood clotting which is not usually something we want to do during pregnancy. As long as a woman is eating plenty of green, leafy veggies she should meet her daily requirement of vitamin K1 (phytomenadione).

When vitamin K2 (menaquinone) is an ingredient in a calcium supplement then that would be fine to take during pregnancy. It is best to take calcium supplements at least 2 hours away iron and zinc supplements. These minerals antagonise calcium and may interfere with absorption.
