Protein Needs During Pregnancy: How Much You Really Need

A protein shortfall during pregnancy is easy to miss, because you can hit your daily calorie goals and still fall short on protein specifically. A commonly cited target is 1.2 to 1.6 grams of protein per kilogram of body weight. That range matters because protein supplies the building blocks for hormones, neurotransmitters, immune cells, and the tissues your baby is building from scratch. The good news is that closing the gap is doable with a few smart food swaps and, when helpful, a clean protein powder.

Why Protein Needs Climb During Pregnancy

Your body is building a whole person, and that takes raw material. Protein supplies the building blocks for hormones, neurotransmitters, immune cells, and much more. During pregnancy, demand climbs steadily as blood volume expands and your baby's organs form.

Here's the part that surprises a lot of expecting moms: research has looked specifically at how protein intake during pregnancy, not just overall calorie intake, relates to fetal development and long-term health outcomes for the child. In other words, it isn't only about eating enough food overall. It's specifically about eating enough protein.

Even in a lower-protein pregnancy diet, the signals sent to a growing baby continue to guide organ formation and development, and protein plays a meaningful role in shaping those signals. Research on maternal nutrition and fetal programming has found that low maternal protein intake can influence epigenetic changes in offspring related to muscle development, essentially "programming" the body toward conserving muscle mass, a biological adaptation thought to reflect the nutritional environment a baby is born into. It's a striking example of how a mother's diet can shape a child's physiology well beyond birth.

How Much Protein You Really Need

Most research recommends 1.2-1.6g of protein per kg of body weight during pregnancy.

Quick estimate: multiply your weight in kilograms by 1.2 and by 1.6 to get your personal range.

A few examples to make it concrete:

• 60 kg (about 132 lb): roughly 72–96 grams of protein daily

• 70 kg (about 154 lb): roughly 84–112 grams daily

• 80 kg (about 176 lb): roughly 96–128 grams daily

Can you get too much protein during pregnancy? For most healthy pregnancies, the goal is spreading protein intake across meals, not megadosing. Your OB or midwife can help set a target that fits your body and your labs. A lab review consultation with our team can also help you read your numbers with context.

Is Protein Powder Safe During Pregnancy?

For most healthy pregnancies, a clean protein powder can be a convenient way to close the gap between what you're eating and what your body needs. As always, clear any new supplement with your OB or midwife first.

Here's what to look for on the label:

• Third-party tested for purity and heavy metals

• A short, recognizable ingredient list

• No proprietary blends hiding herbs or stimulants.

• No added caffeine or "energy" botanicals

• A protein source you tolerate well, such as whey or pea

Clean and Lean Protein Sources to Trust

Whole foods should come first; powders are there to fill in the gaps. Reliable protein-rich foods worth building meals around:

• Eggs and Greek yogurt, for easy, complete protein

• Chicken, turkey, and well-cooked lean beef

• Fully cooked salmon and low-mercury fish

• Lentils, beans, and tofu for plant-based options

• Cottage cheese and chia seeds to boost protein-rich snacks

Where Collagen Fits

Collagen is a protein worth knowing about, but it isn't a complete protein on its own. Options like Bioactive Collagen Complex Daily Foundational Support by Vital Proteins may help support skin and connective tissue as part of a varied diet, not as your only protein source.

Whey vs. Plant Protein for Expecting Moms

Both can work well; the right choice depends on how you feel and what you tolerate.

Whey is a complete protein that digests quickly. If dairy sits well with you, a simple option like Whey Protein Vanilla or Whey Protein Unflavored keeps things clean.

Prefer plant-based, or sensitive to dairy? Pea protein is a solid choice, and Plant Protein Vanilla offers an easy vanilla base for shakes.

One note on quality: research has also examined how dietary protein intake before and during pregnancy relates to gestational diabetes risk, one more reason to lean toward whole-food-forward protein sources and stay in touch with your provider about your overall diet.

Still, a high-protein diet built mainly from whole foods is generally the best foundation. If you do rely on powder, whey provides all nine essential amino acids in a complete profile per serving, while pea protein is slightly lower in methionine and is typically paired with rice protein to round out its amino acid profile. Both are legitimate, viable ways to help meet your daily protein goals.

Easy High-Protein Snacks and Shakes

One of the simplest ways to hit a high-protein day is to make protein the foundation of your snacks, not an afterthought:

• Greek yogurt with chia seeds and berries

• A vanilla protein shake blended with milk or a plant-based base

• Cottage cheese with sliced fruit

• Hard-boiled eggs with whole-grain crackers

• Hummus and vegetables with a serving of peanut butter

Key Takeaways

• A common target is 1.2 to 1.6 grams of protein per kilogram of body weight during pregnancy.

• Protein supplies building blocks for hormones, neurotransmitters, immune cells, and fetal tissue development.

• Maternal protein intake may influence fetal programming, including epigenetic factors related to muscle development.

• Whey and plant proteins can both work well, look for clean, third-party tested options.

• Always talk with your OB or midwife before adding any new supplement during pregnancy.

Frequently Asked Questions

How much protein do I need during pregnancy?

Research generally recommends 1.2 to 1.6 grams of protein per kilogram of body weight during pregnancy. For many women, that lands somewhere between 70 and 120 grams a day, though the exact number depends on your weight and stage of pregnancy. Your OB or midwife can help you set a personalized target.

What food sources of protein are safe during pregnancy?

Most whole-food proteins are safe during pregnancy: eggs, Greek yogurt, well-cooked lean meats and poultry, low-mercury cooked fish, beans, lentils, and tofu. Fully cook all animal proteins, and avoid high-mercury fish along with raw or undercooked meat, poultry, and fish. Spreading protein intake across meals throughout the day helps you consistently hit your target.

Is it safe to take a protein powder or supplement while pregnant?

For most healthy pregnancies, a clean protein powder can be a safe way to help close a protein gap, once cleared by your OB or midwife. Look for third-party testing, a short ingredient list, and no added caffeine, stimulants, or hidden herbal blends. Whey and pea proteins are both common, well-tolerated choices, best used as one part of an otherwise varied diet.

Which specific protein powder is a good fit during pregnancy?

Choose a simple, third-party tested powder that matches your tolerance. Whey Protein Vanilla or Whey Protein Unflavored work well if dairy agrees with you, while Plant Protein Vanilla is an easy dairy-free option. Skip proprietary blends and added botanicals, and confirm your choice with your prenatal provider first.

Are store-bought protein shakes and bars safe during pregnancy?

Homemade shakes made from a clean protein powder, milk or a plant base, and fruit are usually a safe, simple way to boost protein. For pre-made shakes or bars, look for a recognizable ingredient list and avoid anything with added caffeine, herbal "energy" ingredients, or unfamiliar additives — and keep an eye on added sugars or sugar alcohols if they tend to upset your stomach. As with any new product, it's worth running it by your OB or midwife.

Does collagen count toward my daily protein goal during pregnancy?

Collagen can be a helpful addition for skin and connective tissue support, but it isn't a complete protein on its own and shouldn't be relied on as your main protein source. Think of it as a supplement to a varied, protein-rich diet rather than a replacement for whole-food or complete protein sources.
