Use care-team guidance first. Nutritional needs during pregnancy are highly individual. This page provides educational ranges and questions to discuss with your midwife, obstetrician, clinician, or registered dietitian; it does not set a personal pregnancy target.

Protein Ranges to Discuss by Trimester
First Trimester
Weeks 1–13
Often modestly above baseline
Protein needs are often only modestly elevated. If nausea is present, ask your care team how to keep intake steady with small, food-first options.
Second Trimester
Weeks 14–27
Often higher than baseline
Fetal and maternal tissue growth increases. Use your care team's advice for the right range rather than assuming a fixed gram target.
Third Trimester
Weeks 28–40
Often highest late in pregnancy
Protein requirements are often highest late in pregnancy. If appetite drops, reflux worsens, or weight gain is outside your plan, ask your care team before forcing larger portions.
Questions to Ask Your Care Team
- What protein range fits my trimester, pre-pregnancy weight, nausea, labs, and fetal growth?
- Are there foods, supplements, mercury limits, gestational diabetes concerns, or medical conditions that change my plan?
- What symptoms or weight-change patterns should prompt a nutrition or medical check-in?
Pregnancy Protein Foods and Food-Safety Checks
| Food | Protein | Safety Note |
|---|---|---|
| Fully cooked eggs (2 large) | 12g | Safe when fully cooked. Rich in choline — critical for fetal brain development. |
| Chicken breast (150g, cooked) | 46g | Safe fully cooked. Versatile, lean, and well-tolerated. |
| Salmon (150g, cooked) | 34g | Low-mercury, rich in DHA for fetal brain. 2–3 servings/week. |
| Greek yoghurt (200g) | 18–20g | Safe if pasteurised. Rich in calcium and probiotics. |
| Cottage cheese (200g) | 22g | Safe if pasteurised. Excellent leucine source, easy to digest. |
| Lentils (200g, cooked) | 18g | Safe. Rich in folate — important for neural tube development. |
| Tofu (200g, firm) | 16g | Safe. Good plant-based complete protein option. |
| Tuna (90g, canned) | 20g | Limit to 2 servings/week (light tuna preferred). Moderate mercury. |
Frequently Asked Questions
How much protein do I need during pregnancy?
Protein requirements generally increase during pregnancy. The current DRI RDA is 1.1g/kg per day, while pregnancy-specific research discusses higher needs later in pregnancy. Use these figures as discussion points with your OB-GYN, midwife, clinician, or registered dietitian rather than as a personal prescription.
Why does protein need increase during pregnancy?
Protein is the primary building block for fetal tissue development — including muscles, organs, the brain, skin, and placenta. During the second and third trimesters, when the fetus grows most rapidly, protein requirements nearly double compared to pre-pregnancy. Additionally, the mother's blood volume expands by up to 50%, requiring more protein for haemoglobin and plasma protein synthesis. Inadequate protein during pregnancy is associated with low birth weight and impaired fetal organ development.
How should I think about higher protein during pregnancy?
Pregnancy protein planning should be food-first and care-team guided. Very high protein intakes are not necessary for most people and have limited study in pregnant populations. Ask your care team how trimester, nausea, fetal growth, labs, food safety, and medical history should shape your range.
Which protein foods are usually appropriate during pregnancy?
Safe, high-quality protein sources during pregnancy include: fully cooked eggs and egg whites, cooked poultry (chicken, turkey), low-mercury fish (salmon, cod, tilapia, trout — up to 2–3 servings/week), legumes (lentils, chickpeas, black beans), Greek yoghurt and cottage cheese, tofu and tempeh, and pasteurised dairy. Avoid: raw or undercooked meat and eggs, high-mercury fish (shark, swordfish, king mackerel, tilefish), and unpasteurised soft cheeses.
Can I use protein powder while pregnant?
Protein powder can be a practical food supplement for some people, especially when nausea limits solid food, but pregnancy supplement choices should be cleared with your OB-GYN, midwife, clinician, or registered dietitian. Avoid using powders, mass gainers, pre-workouts, or blended supplement products as a substitute for individualized care.
How does protein need change by trimester?
First trimester: protein requirements are usually only modestly above pre-pregnancy baseline. Second and third trimesters: requirements increase as fetal and maternal tissue growth accelerates. Current DRI guidance sets pregnancy protein at 1.1g/kg/day; newer indicator amino acid oxidation studies suggest late-pregnancy needs can be around 1.5g/kg/day. Personal targets should be confirmed with your care team.
