Quick Answer
The widely-cited number is 71 grams of protein per day — that's the ACOG/DRI baseline (1.1 g/kg for a 65 kg woman). But here's what nobody tells you: that single number is the same for week 5 and week 38, and 2022 research using indicator amino acid oxidation suggests late-pregnancy needs may be closer to 1.52 g/kg (around 99g for the same woman). The full trimester-by-trimester table, your personal kg-based number, and 20 snacks adapted to vegan, vegetarian, gluten-free, and dairy-free diets are below.
Why 71g — And Why That Number Is Probably Low
So here's the thing. The 71g figure comes from the 2005 Dietary Reference Intakes (DRIs), which set the pregnancy RDA at 1.1 g/kg body weight per day for all stages of pregnancy. ACOG references this same number in its Nutrition During Pregnancy patient guidance. For a 65 kg (143 lb) woman, that math gives you 71.5g.
I'm not gonna lie — when I first read this I assumed it was settled science. It's not. A 2022 review in Advances in Nutrition (PMC4942872) using the indicator amino acid oxidation (IAAO) method — basically a more sensitive way to measure protein adequacy — found that healthy pregnant women actually need:
- Early pregnancy (weeks 11-20): ~1.22 g/kg/day (about 39% higher than the EAR)
- Late pregnancy (weeks 30-38): ~1.52 g/kg/day (about 73% higher than the EAR)
The reason matters: most fetal and maternal tissue is deposited in the third trimester — placenta, breast tissue, blood volume, baby's actual body. The static 71g number averages this out. The trimester-adjusted approach pulls it forward. I asked my OB about this and she basically said "the DRI is a floor, not a target — aim higher in T3 if you can."
If you're already tracking choline obsessively (no judgment, I did too — see our choline trimester guide), the same logic applies to protein. The full trimester table is in the next section.
Your Trimester-Adapted Protein Number (Not Just 71g)
Calculate your personal target using your pre-pregnancy weight in kg (or divide pounds by 2.2). The DRI column is the "safe minimum" — the IAAO column is the updated research-based estimate.
| Trimester | Weeks | DRI baseline (1.1 g/kg) | IAAO research (g/kg) | Example: 55 kg woman | Example: 65 kg woman | Example: 75 kg woman |
|---|---|---|---|---|---|---|
| First (T1) | Weeks 1-13 | 1.1 g/kg | ~1.22 g/kg | 60-67 g | 71-79 g | 82-92 g |
| Second (T2) | Weeks 14-27 | 1.1 g/kg | ~1.35 g/kg (mid) | 60-74 g | 71-88 g | 82-101 g |
| Third (T3) | Weeks 28-40 | 1.1 g/kg | ~1.52 g/kg | 60-84 g | 71-99 g | 82-114 g |
| Postpartum (lactating) | 0-6 months | 1.3 g/kg | ~1.5 g/kg | 71-83 g | 84-98 g | 98-113 g |
Use the DRI column if your OB is conservative or you're just starting to track. Use the IAAO column if you're an active researcher type, lifting weights, carrying twins, or your OB has flagged you for low protein. Twins, gestational diabetes, or hyperemesis recovery generally push you toward the higher end — talk to your OB-GYN or a registered dietitian who specializes in pregnancy.
20 High-Protein Snacks by Diet (Omnivore, Vegetarian, Vegan, GF, DF)
Protein per serving from USDA FoodData Central. I picked options that are actually portable — not "blend a smoothie with five ingredients" recipes. Half of pregnancy snacking is "what can I grab in 30 seconds when the nausea breaks."
| # | Snack | Serving | Protein (g) | Diet tags | Best for |
|---|---|---|---|---|---|
| 1 | Plain Greek yogurt (nonfat) | 1 cup (227 g) | ~24 | Vegetarian, GF | Easy T1 breakfast |
| 2 | Cottage cheese (low-fat) | 1 cup (226 g) | ~28 | Vegetarian, GF | Slow-digesting bedtime |
| 3 | Hard-boiled eggs | 2 large | ~12 | Vegetarian, GF, DF | Grab-and-go all trimesters |
| 4 | Edamame (shelled, steamed) | 1 cup (155 g) | ~18 | Vegan, GF, DF | Complete plant protein |
| 5 | Roasted chickpeas | 1/2 cup (82 g) | ~10 | Vegan, GF, DF | Crunchy, shelf-stable |
| 6 | Hummus + carrots | 1/4 cup hummus | ~6 | Vegan, GF, DF | Heartburn-friendly |
| 7 | Tuna pouch (chunk light) | 2.6 oz (74 g) | ~17 | Pescatarian, GF, DF | Low-mercury picks only |
| 8 | Canned wild sardines | 1 tin (92 g) | ~21 | Pescatarian, GF, DF | Omega-3 + protein |
| 9 | Cooked shrimp | 4 oz (113 g) | ~24 | Pescatarian, GF, DF | Fully cooked only |
| 10 | Turkey rollups (deli-free) | 3 oz home-cooked | ~22 | Omnivore, GF, DF | Heat deli to steaming if used |
| 11 | Tofu cubes (firm, baked) | 1/2 cup (126 g) | ~10 | Vegan, GF, DF | Complete protein |
| 12 | Tempeh slices (pan-cooked) | 3 oz (84 g) | ~16 | Vegan, GF, DF | Higher than tofu |
| 13 | Lentil soup (cup) | 1 cup (240 ml) | ~9 | Vegan, GF, DF | T1 nausea-friendly |
| 14 | Almond butter on apple | 2 tbsp | ~7 | Vegan, GF, DF | Protein + fiber combo |
| 15 | Pumpkin seeds (roasted) | 1/4 cup (32 g) | ~9 | Vegan, GF, DF | Iron + magnesium bonus |
| 16 | Black bean dip + rice crackers | 1/3 cup | ~8 | Vegan, GF, DF | Quick lunch add-on |
| 17 | Smoked salmon (cold-smoked: cook first) | 2 oz (56 g) | ~11 | Pescatarian, GF, DF | Hot-smoked is safe; cold-smoked: heat to 165F |
| 18 | String cheese (mozzarella) | 2 sticks | ~14 | Vegetarian, GF | Pasteurized only |
| 19 | Quinoa bowl (cooked) | 1 cup (185 g) | ~8 | Vegan, GF, DF | Complete grain protein |
| 20 | Pea protein smoothie (unsweetened) | 1 scoop (25 g) | ~20 | Vegan, GF, DF | When nothing else stays down |
A few of these — especially #17 cold-smoked salmon — have safety footnotes. The FDA's "Best Choices" fish list is the source I trust for which fish to eat and how often. Refrigerated smoked seafood is on the CDC's listeria-risk list unless heated to 165°F.
How to Hit Your Number on Hard Days (Nausea, Aversion, Exhaustion)
Look, I'm not a nutritionist, but I spent week 8 surviving on crackers and the protein guilt was real. Here's what actually worked when food felt impossible:
- Cold, plain, bland wins: Cottage cheese (28g), Greek yogurt (24g), and hard-boiled eggs (6g each) deliver protein without strong smells. If yogurt tastes off — and it did for me by week 9 — see our cottage cheese in pregnancy guide for aversion swaps.
- Sip when you can't chew: A pea or whey protein shake in oat milk delivers 20g+ when bites are nauseating. Look for unsweetened, third-party-tested brands (Informed Sport or NSF Certified).
- Stack tiny wins: 2 eggs (12g) + 1/2 cup edamame (9g) + 1 cup Greek yogurt (24g) = 45g before lunch. The rest of the day just needs 25-30g.
- Lean on bedtime casein: Cottage cheese before bed is the slow-digesting trick athletes use. It also doubles as a heartburn-friendly snack for many.
If you can't keep food down for 24+ hours or you're losing weight in T1, that's not "just morning sickness" — talk to your OB about hyperemesis gravidarum. Protein is important; not dehydrating yourself is more important first.
Diet-Specific Protein Strategies (Vegan, Vegetarian, GF, DF)
Vegan pregnancy: amino acid combining is real, but easier than you think
The Academy of Nutrition and Dietetics position is clear: well-planned vegan diets are appropriate for all stages of pregnancy. The "incomplete protein" panic from the 1970s is outdated — your liver pools amino acids across the day, you don't need to combine them in one meal. That said, building most meals around soy (tofu, tempeh, edamame), legumes (lentils, chickpeas, black beans), and whole grains (quinoa, oats, brown rice) covers all 9 essential amino acids reliably.
Vegan pregnancy non-negotiables (beyond protein): B12 supplement (non-negotiable for vegans — your liver stores get depleted), DHA from algae, iron monitoring (plant iron is less bioavailable — pair with vitamin C), and choline (egg yolks are the easy source; vegans need to deliberately hit choline through soy lecithin, peanuts, broccoli — see our choline absorption guide).
Gluten-free: watch the nutrient gap, not just gluten
GF diets often run low in calcium, iron, fiber, zinc, B vitamins, vitamin D, and magnesium because most enriched grain products contain gluten — a known nutrient gap covered in the NIH macronutrient pregnancy guidance. Lean into naturally GF protein anchors: quinoa, lentils, eggs, dairy, fish, meat, tofu — and choose a GF prenatal that fills the gaps.
Dairy-free: replace casein density with legume volume
Dairy is the densest "easy" protein category (28g per cup of cottage cheese). Without it, you'll lean harder on edamame, tempeh, lentils, eggs (if vegetarian), and fish. Fortified soy milk delivers ~7g protein per cup and is the closest 1-to-1 swap for dairy in cereal/smoothies. Almond and oat milk are not protein swaps — they're closer to 1g per cup.
Quick Daily Math: Hit 71g Without Counting Every Bite
You don't actually need to log every gram. Use the anchor protein framework: one solid protein source per meal/snack, and you'll land in range without tracking.
- Breakfast anchor: 2 eggs OR 1 cup Greek yogurt OR 1 cup cottage cheese (12-28g)
- Mid-morning snack: handful of nuts + edamame OR string cheese (8-15g)
- Lunch anchor: Tuna pouch + crackers OR lentil bowl OR turkey wrap (17-25g)
- Afternoon snack: hummus + carrots OR roasted chickpeas (6-10g)
- Dinner anchor: salmon, chicken, tofu, or tempeh portion (20-35g)
Add it up: ~70-95g per day. T1 baseline territory if you eat the lower end, T3 IAAO territory at the upper end. No spreadsheet needed. (If you do want to track, the Mombite pregnancy meal planner has a built-in protein counter that adjusts to your trimester and pre-pregnancy weight — that's literally why we built it.)
Frequently Asked Questions
Is 71 grams of protein really enough for late pregnancy?
The DRI says yes — 71g is the baseline for an average-weight pregnant person across all trimesters. But the 2022 IAAO research from the NIH PMC review suggests late-pregnancy needs may be closer to 1.52 g/kg/day, which for a 65 kg woman is closer to 99g. If your OB is conservative, 71g is fine. If you're carrying twins, recovering from hyperemesis, or have a higher activity level, aim higher in T3.
Can too much protein be harmful during pregnancy?
For healthy pregnancies, evidence of harm from high-protein diets is weak. Older studies on "high-protein supplementation" used isolated supplements at doses 25g+ above intake, not whole-food protein, and showed mixed results. Whole-food protein from the foods in the table above is considered safe at the levels most people would actually eat. If you have kidney disease or any pre-existing condition, your OB-GYN or a renal dietitian needs to set your number — don't freelance it.
Do I need a protein powder during pregnancy?
Not if you can eat enough whole-food protein. Powders are a tool, not a requirement. If nausea, aversion, or appetite loss are making it hard to hit your number, an unsweetened, third-party-tested pea or whey protein (Informed Sport or NSF Certified) is reasonable. Avoid powders with proprietary blends, undisclosed herbs, or "fat burner" additives — pregnancy is not the time to experiment.
What about jerky, protein bars, and processed protein snacks?
Read labels carefully. Beef and turkey jerky should be commercially packaged and shelf-stable (not deli-style fresh jerky, which has listeria risk). Protein bars vary wildly — look for ones with whole-food ingredients, under 10g added sugar, and no sugar alcohols (which can cause GI distress in pregnancy). Recent research on ultra-processed foods and pregnancy outcomes is worth reading before stocking your pantry with bars.
Is plant protein as good as animal protein for pregnancy?
Yes, when the diet is well-planned. Soy (tofu, tempeh, edamame) and quinoa are complete proteins on their own. Legumes paired with grains across the day cover all essential amino acids. The Academy of Nutrition and Dietetics confirms well-planned vegan and vegetarian diets are safe for pregnancy. The non-negotiables are B12 supplementation, DHA from algae, iron monitoring, and choline awareness — all four are easier to miss on plant-based diets than protein itself.
