Reaching a nutritional status requires consistent intake, which for some may include a mix of a healthy diet and supplementation. It’s important to help maintain essential nutrient levels before pregnancy, since those initial first weeks of pregnancy are critical (and someone might not even realize they're expecting yet). That's why eating a mostly-balanced diet — and starting a prenatal multivitamin early — can have a positive impact. Nevertheless, while nutrition plays a foundational role during pregnancy, the approach shouldn’t vary all that much from supporting the body with a healthy diet during any other life stage.
