Multivitamins and Miscarriage

Multivitamins lower miscarriage risk by 57%

In the final adjusted model, any use of vitamins during pregnancy was associated with decreased odds of miscarriage (odds ratio = 0.43) in comparison with no exposure.

Vitamins do not prevent miscarriage, but prevent pre-eclampsia, boost chances for twins

No difference was seen between women taking any vitamins compared with controls for total fetal loss (relative risk 1.05, not statistically significant), early or late miscarriage (relative risk 1.08, not statistically significant) or stillbirth (relative risk 0.85, not statistically significant) and most of the other primary outcomes, using fixed-effect models. For the other primary outcomes, women given any type of vitamin(s) compared with controls were less likely to develop pre-eclampsia (relative risk 0.68, four trials, 5580 women) and more likely to have a multiple pregnancy (relative risk 1.38, three trials, 20,986 women). Taking vitamin supplements, alone or in combination with other vitamins, prior to pregnancy or in early pregnancy, does not prevent women experiencing miscarriage or stillbirth. However, women taking vitamin supplements may be less likely to develop pre-eclampsia and more likely to have a multiple pregnancy.
