Ive never heard of that i took prenatals with my first and this one
I am taking folic acid and b complex tabs. Apart from that the powder is a nutrition supplement named liptomama.
Is there a particular reason your doctor told you to drink it? If it's really making you sick maybe ask if it's OK for you to stop it? Are you taking a prenatal vitaim?
I have never herd of a milk supplement? But if you can't stomach it try eating first then like ten min later then drink it. If that still dosent work take a prenatal vitamin instead:)
