Primary Outcome Measures:
  • Gestational diabetes [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Subjects will have baseline blood levels drawn for fasting glucose, folic acid, vitamin B12, homocysteine and vitamin D measurements. They will be randomized to take either standard of care dose of folic acid or an additional 4 milligrams of folic acid for the duration of their pregnancy. The blood levels will again be drawn for fasting glucose, folic acid, vitamin B12, homocysteine and vitamin D measurements.


Secondary Outcome Measures:
  • Gestational hypertension [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Subjects will have baseline blood levels drawn for fasting glucose, folic acid, vitamin B12, homocysteine and vitamin D measurements. They will be randomized to take either standard of care dose of folic acid or an additional 4 milligrams of folic acid for the duration of their pregnancy. The blood levels will again be drawn for fasting glucose, folic acid, vitamin B12, homocysteine and vitamin D measurements.
