    Questions Fréquentes

    When should I start taking prenatal vitamins?

    Ideally, start at least one month before conception. Folic acid is most critical in the first 4 weeks when the neural tube forms, often before you know you are pregnant.

    Do I need the same nutrients in every trimester?

    Core nutrient needs remain similar throughout pregnancy. Calorie needs increase in the 2nd and 3rd trimesters. Iron needs are highest in the 3rd trimester.

    Can I get enough from food alone?

    A balanced diet provides many nutrients, but most healthcare providers recommend a prenatal supplement to ensure adequate folic acid, iron, and vitamin D intake.
