Effects

Pregnancy
Needed nutrient support may differ by trimester. Dosing and product choice should be reviewed with a provider.
Mother
May help meet higher pregnancy needs for folate, iron, iodine, vitamin D, and other nutrients. Some products cause nausea or constipation.
Baby
May support fetal development by helping prevent folate deficiency. Too much vitamin A as retinol can be harmful.

Trimester Notes

1st Trimester
Folic acid is especially important early in pregnancy and before 12 weeks.
2nd Trimester
Continue prenatal support as advised. Check iron, calcium, iodine, and vitamin D intake.
3rd Trimester
Continue only as advised by your provider. Iron needs may be important if anemia is present.

Risk-Benefit Note

The benefit is nutrient support during pregnancy, especially folate. The risk is excess or unbalanced ingredients in some products. Your provider can help choose the right formula for your needs.
