This is what I take...(here on number 8 I have it worked out to a near science-since pre-natals have always made me sick). After I eat my first breakfast...I take a Centrum chewable multi vitamin, two 400mcg folic acids, and two Naturol lemon flavored Omega 3-6-9s. After second lunch, I take a b-complex and two more Omega 3-6-9s. Before bed I take 1200mg of Calcium=d, and 500mg of magnesium. If you can't swallow the giant honkin' calcium--there are yummy flavored chewable calcium wafers--you have to take your calcum w/magnesium though. Calcium before bed helps you sleep more soundly, and magnesium makes the calcium better absorbed, and keeps you from getting constipated.
I also drink SPirutein most days...primarily because I can't get my 75-80gs of protein without it.
