Bone Mineral and Preeclampsia Shield
A bone mineral most people fall short on, and one of the few supplements with strong trial evidence for lowering preeclampsia risk where dietary calcium is low.
The Fetal Brain and Preterm-Birth Fatty Acid
A fatty acid that builds the fetal brain and eye and, in good trials, lowers the risk of preterm birth, with a real twist about who actually benefits.
The Nutrient and the Contaminant in One Food
The same food that is the best natural source of DHA also carries mercury, and fear of the contaminant has driven many pregnant people to underconsume the nutrient.
When the Diet Becomes the Treatment
In gestational diabetes, nutrition is not a supplement question but the first-line treatment itself, and most cases are managed by diet alone.
The Oxygen-Carrying Mineral
Pregnancy roughly doubles iron demand to build maternal blood volume and supply the growing fetus, and deficiency is the most common nutritional shortfall in pregnancy worldwide.
Essential, and the One to Watch the Ceiling On
A nutrient pregnancy genuinely needs, and the clearest example of a vitamin where too much, in the wrong form, causes serious birth defects.
The First-Line Answer to Morning Sickness
The evidence-based first step for nausea and vomiting of pregnancy, recommended by ACOG, alone or paired with doxylamine.
How Much "Eating for Two" Really Means
"Eating for two" is one of the most persistent prenatal myths; the actual extra energy need is modest and weight-gain targets depend on starting weight.
The Herbal Tea Aisle, Sorted by Evidence
The pregnancy-tea aisle ranges from genuinely evidence-backed (ginger) to traditional-but-unproven to better avoided, and the labels rarely tell you which is which.
Cramps, Calm, and Cautious Evidence
Widely taken for leg cramps and sleep, often below the recommended intake to begin with, but the routine-supplementation evidence is thinner than the popularity suggests.
The Contested Sunshine Vitamin
A nutrient everyone agrees matters, where the experts genuinely disagree on how much, what blood level to aim for, and whether to screen at all.
