First Trimester

First Trimester Meal Plan

This first trimester meal plan covers weeks 1 to 13, when your baby's organs are forming and your appetite may be anywhere from ravenous to nonexistent. The meals lean on folate-rich greens, eggs for choline, ginger for nausea, and small, frequent portions of protein that are easier to keep down than one big plate.

You do not need extra calories yet. What you need is consistency: something in your stomach every two to three hours, a prenatal with methylfolate, and grace on the days when toast is all you can manage.

Supplements for the First Trimester

Talk to your provider before starting anything new. These are the supplements most often recommended for this phase.

Prenatal Vitamin
1 daily (with food)
Covers baseline folate, iron, B12, and other essentials. Your safety net for any gaps in diet.
When: All trimesters, ideally starting before conception
DHA / Omega-3
200-300mg DHA daily
Critical for baby's brain and eye development. Most prenatals include too little or none.
When: All trimesters, especially 2nd and 3rd
Choline
450mg daily
Supports baby's brain development and reduces neural tube defect risk. Only 5-10% of pregnant women get enough from diet alone.
When: All trimesters
Vitamin D
2,000-4,000 IU daily
Supports bone development and immune function. Deficiency is extremely common, especially in northern latitudes.
When: All trimesters
Magnesium Glycinate
200-400mg daily
Helps with leg cramps, sleep, constipation, and may reduce preeclampsia risk.
When: All trimesters, especially helpful in 2nd and 3rd
Iron (if needed)
27mg daily (more if anemic)
Blood volume increases 50% during pregnancy. Iron deficiency anemia is common and causes fatigue.
When: All trimesters, test levels around 28 weeks

First Trimester Meal Plan Questions

What should I eat in the first trimester?

Focus on folate (leafy greens, lentils, citrus), choline (eggs), iron (beef, beans, spinach), and enough protein to hit roughly 80 grams a day. Small meals every few hours help with nausea. Calorie needs stay about the same as before pregnancy.

What if I cannot keep food down in the first trimester?

Eat whatever stays down, in small amounts, often. Cold foods, plain carbohydrates, ginger, and protein-first snacks tend to help. Keep your prenatal going, try taking it at bedtime, and call your provider if you cannot keep liquids down for a day.

How much protein do I need in the first trimester?

Most guidance lands around 75 to 100 grams a day. This plan targets 80 grams, spread across breakfast, lunch, dinner, and two snacks so no single meal has to carry the load.
