Demystifying Prenatal Vitamins

This Prenatal Vitamin Calculator compares your current supplement stack against guidelines from the American College of Obstetricians and Gynecologists (ACOG). While a balanced diet is the best source of nutrients, the massive physical demands of building a new human require supplementation. The "big three" nutrients you must monitor are Folic Acid, Iron, and DHA.

Gummy Vitamins: The Hidden Trap

Many women switch to gummy prenatal vitamins in the first trimester because large pills trigger nausea. What many don't realize is that gummy vitamins almost never contain Iron. The metallic taste of iron is incredibly difficult to mask in a sweet gummy, and iron poses a toxicity risk to young children who might mistake the gummies for candy. If you take gummies during your 2nd and 3rd trimesters, you will likely need a separate iron pill to prevent maternal anemia.

Dietary Adjustments

If you eat a plant-based (vegan or vegetarian) diet, your nutrient targets shift. Plant-based (non-heme) iron is absorbed much less efficiently than meat-based (heme) iron, meaning vegans need to consume nearly 1.5 times the standard iron target. Furthermore, DHA is primarily found in marine life. Vegans should seek out an algae-based DHA supplement to ensure proper fetal brain development.
