Hi! I am a student, and currently taking nutrient metabolism. Choline
is made in the body from methylation of serine. As you all know,
serine is an amino acid. So, I guess if someone were short on serine,
then ok, the body would not be able to metabolize choline well. But is
it not true that pregnant women need more PRO than others? So maybe it
is just a matter of precaution? It also says in my text that AI should
be obtained through dietary consumption of animal products and foods
containing fats. --this may not be much help to your question
Lorraine, but I thought I would just share with you what a current
student has in her texts.
