# Best Protein Powder for Breastfeeding > The best protein powders for breastfeeding, compared on protein, calories, testing and sweeteners, plus what the evidence says about fenugreek and lactation blends. - **URL**: https://www.best-proteinpowder.com/best-protein-powder-for-breastfeeding/ - **Updated**: 2026-11-08 - **Author**: [Best Protein Powder Editorial Team](https://www.best-proteinpowder.com/authors/editorial-team/) - **Publisher**: [Best Protein Powder](https://www.best-proteinpowder.com/) --- Seven protein powders and shakes for nursing parents, chosen on protein per serving, calories, independent testing and sweeteners, with an honest look at fenugreek and other lactation add-ins. Talk to your doctor or a lactation consultant before starting any supplement. **How we rank:** We judge every powder on the label, not the marketing: protein per scoop, cost per 25 g of protein, the full ingredient list and third-party testing. No paid placements, and commission never sets a ranking. [Read our methodology](https://www.best-proteinpowder.com/how-we-test/) The best protein powder for breastfeeding gives you protein and, when you need it, calories, without herbs or additives that you then have to wonder about every time the baby is fussy. Ritual's Pregnancy and Postpartum shake is our top pick: 20 g of pea protein, 250 mg of choline and no lactation herbs, per its label. Huel Black Edition is the choice when you are missing whole meals and need about 400 calories in a glass. Thorne Whey Protein Isolate is the best certified dairy option, and Premier Protein is the easiest one-handed shake for night feeds. A protein powder will not increase your milk supply, and the evidence for lactation blends such as fenugreek is weak. This is not medical advice; if supply is a worry, see an IBCLC lactation consultant or your doctor. ## Our Top Picks | Award | Product | Why | | --- | --- | --- | | Best Overall for Breastfeeding | [Ritual Essential Protein Daily Shake Pregnancy & Postpartum](https://www.best-proteinpowder.com/best-protein-powder-for-breastfeeding/#ritual-essential-protein-pregnancy-postpartum) | The simplest pick for nursing parents: a clean, modest protein dose with extra choline and no lactation herbs to second-guess. | | Best for Extra Calories | [Huel Black Edition](https://www.best-proteinpowder.com/best-protein-powder-for-breastfeeding/#huel-black-edition) | The pick for parents who are skipping meals altogether in the newborn weeks and need calories as much as protein. | | Best Certified Whey | [Thorne Whey Protein Isolate](https://www.best-proteinpowder.com/best-protein-powder-for-breastfeeding/#thorne-whey-protein-isolate) | The best-documented dairy protein for nursing parents who want independent testing first. | | Best Short-Label Whey | [Truvani Organic Whey Protein Powder, Vanilla](https://www.best-proteinpowder.com/best-protein-powder-for-breastfeeding/#truvani-organic-whey-protein) | A good flavored choice if you want to keep artificial sweeteners out of your diet while nursing. | | Best One-Handed Shake | [Premier Protein 30g Protein Shake](https://www.best-proteinpowder.com/best-protein-powder-for-breastfeeding/#premier-protein-shake) | The practical pick for the newborn fog: open, drink, done. | | Best Budget Plant | [Orgain Organic Protein Plant-Based Protein Powder](https://www.best-proteinpowder.com/best-protein-powder-for-breastfeeding/#orgain-organic-protein-plant-based) | The low-cost dairy-free option, as long as sugar alcohols agree with you and you check the brand's testing. | | Best Unsweetened Budget | [Naked Whey (Unflavored)](https://www.best-proteinpowder.com/best-protein-powder-for-breastfeeding/#naked-nutrition-naked-whey) | The value pick for parents who blend their own shakes and want nothing on the label but protein. | ## 1. Breastfeeding Protein Powders Compared at a Glance Here is every pick side by side. Protein, calories and sugar are per serving from the label or retailer listings at the time of writing and vary by flavor. Price tier compares cost per serving across this list. | Product | Protein/scoop | Calories | Sugar | Price tier | Certification | | --- | --- | --- | --- | --- | --- | | Ritual Pregnancy & Postpartum | 20 g | 115-120 | 0 g added | Premium | Testing marks listed by brand | | Huel Black Edition | About 40 g | About 400 | Varies by flavor | Mid | None confirmed | | Thorne Whey Isolate | 21 g | About 100 | 2-3 g | Premium | NSF Certified for Sport | | Truvani Organic Whey | About 20 g | About 100 | Low; check label | Mid | USDA Organic | | Premier Protein Shake | About 30 g | About 160 | About 1 g | Budget | None confirmed | | Orgain Organic Plant | 21 g | About 150 | Under 1 g | Budget | USDA Organic | | Naked Whey (unflavored) | About 25 g | About 120 | About 2 g (milk) | Budget | None confirmed | Two questions decide which row is yours. First, do you mainly need protein, or are you so short on time that you are missing meals and need calories too? If it is the second, Huel is in a different category from the rest. Second, can you have dairy? If your baby's doctor has suggested cutting cow's milk, Ritual, Huel and Orgain are the dairy-free options.

The Best Protein Powders for Breastfeeding We ranked these on the label and on public certification records, not on hands-on testing: protein and calories per serving, independent testing, sweeteners and additives, how easy each is to use with a baby in one arm, and price tier at the time of writing. We did not test these products ourselves. Figures come from the brand's label or retailer listings and vary by flavor, so check the panel on the product you buy. Our methods are explained on the [how we test](https://www.best-proteinpowder.com/how-we-test/) page. ### 1. Ritual Essential Protein Daily Shake Pregnancy & Postpartum **Award:** Best Overall for Breastfeeding | **Type:** Pea protein shake formulated for pregnancy and lactation - **Protein per serving:** 20 g (label) - **Calories:** About 115-120 - **Third-party testing:** Testing marks listed by Ritual - **Best for:** A daily shake through lactation Ritual designed this shake for pregnancy and lactation and suggests using it through breastfeeding. Per its label and listings at the time of writing, a roughly 30-31 g serving gives 20 g of organic pea protein in about 115-120 calories, with 250 mg of choline and no added sugar. Ritual describes it as free of stevia and sugar alcohols, and it contains no galactagogue herbs such as fenugreek. It does not replace a postnatal or prenatal vitamin. **Bottom line:** The simplest pick for nursing parents: a clean, modest protein dose with extra choline and no lactation herbs to second-guess. **Pros:** - 250 mg of choline, a nutrient whose Adequate Intake rises to 550 mg during lactation - No fenugreek or other lactation herbs, so nothing that could upset you or the baby - Dairy-free, useful if your baby's doctor has asked you to cut cow's milk - No added sugar per retailer listings **Cons:** - Premium price tier: roughly 2.50-2.70 dollars a serving at prices reported when we checked - About 120 calories, so it does little for the extra energy lactation demands on its own - Pea protein carries a higher average heavy-metal risk than whey, so its testing matters - Essentially one flavor [Check price on Amazon](https://www.amazon.com/dp/B0DQ1MS43J?tag=sktiger-20&linkCode=ll1) ### 2. Huel Black Edition **Award:** Best for Extra Calories | **Type:** High-protein complete meal powder - **Protein per serving:** About 40 g per 90 g - **Calories:** About 400 - **Third-party testing:** None we could confirm - **Best for:** Replacing a missed meal Breastfeeding raises calorie needs, and Huel Black Edition is the most efficient way here to drink a real meal. Per Huel's label at the time of writing, a 90 g serving gives about 400 calories and 40 g of plant protein from pea and brown rice, with fiber, fats and 27 vitamins and minerals. It is sweetened with stevia and a little coconut sugar and comes in 17-meal bags, including an unflavored version. **Bottom line:** The pick for parents who are skipping meals altogether in the newborn weeks and need calories as much as protein. **Pros:** - About 400 calories and 40 g of protein per serving, per the label - A full meal you can drink one-handed during a feed - Fiber and fat keep you full far longer than a plain protein shake **Cons:** - Its vitamin premix overlaps with a prenatal or postnatal vitamin, so check totals - No sport certification we could find - Thick, slightly grainy texture is a common buyer complaint - Too many calories if you only wanted protein [Check price on Amazon](https://www.amazon.com/dp/B0BF5STD3J?tag=sktiger-20&linkCode=ll1) ### 3. Thorne Whey Protein Isolate **Award:** Best Certified Whey | **Type:** NSF Certified for Sport whey isolate - **Protein per serving:** 21 g (label) - **Calories:** About 100 - **Third-party testing:** NSF Certified for Sport - **Best for:** Certified daily whey Thorne's isolate pairs a short ingredient list with NSF Certified for Sport status, per Thorne and NSF at the time of writing, which covers label-claim checks and contaminant screening as well as banned substances. A scoop of about 28 g gives 21 g of protein in roughly 100 calories, with about 2-3 g of sugar depending on flavor, per the label. Whey isolate tends to test lower for heavy metals than plant proteins. **Bottom line:** The best-documented dairy protein for nursing parents who want independent testing first. **Pros:** - NSF Certified for Sport, one of the stricter independent programs - Complete protein, rich in leucine, low in lactose - No herbs, stimulants or lactation blends **Cons:** - Premium price tier per gram of protein - Only a couple of flavors, with 2-3 g of sugar per scoop - Not an option if your baby's doctor has asked you to avoid dairy [Check price on Amazon](https://www.amazon.com/dp/B07978MBRM?tag=sktiger-20&linkCode=ll1) ### 4. Truvani Organic Whey Protein Powder, Vanilla **Award:** Best Short-Label Whey | **Type:** USDA Organic grass-fed whey concentrate - **Protein per serving:** About 20 g (listing) - **Calories:** About 100 - **Third-party testing:** USDA Organic; no sport certification confirmed - **Best for:** Sweetener-conscious parents A USDA Organic whey concentrate that Truvani says comes from grass-fed, pasture-raised cows on certified organic farms. The vanilla version has three ingredients: organic whey protein concentrate, organic vanilla powder and organic monk fruit extract. Retailer listings show about 20 g of protein and roughly 100 calories per scoop at the time of writing. It suits parents who want a flavored shake with no artificial sweeteners or sugar alcohols. **Bottom line:** A good flavored choice if you want to keep artificial sweeteners out of your diet while nursing. **Pros:** - Three ingredients with monk fruit as the only sweetener - USDA Organic dairy - No sucralose, acesulfame potassium, stevia or sugar alcohols **Cons:** - No sport certification we could confirm - Concentrate carries more lactose than an isolate - About 20 g of protein at a mid-to-premium price; we could not confirm a stable list price [Check price on Amazon](https://www.amazon.com/dp/B0F8PF5KJ9?tag=sktiger-20&linkCode=ll1) ### 5.

Per the label at the time of writing, an 11 fl oz carton gives about 30 g of protein from milk protein concentrate and calcium caseinate, about 160 calories and about 1 g of sugar. It is shelf-stable, so a few can live in the diaper bag or on the nightstand for 3 a.m. feeds. **Bottom line:** The practical pick for the newborn fog: open, drink, done. **Pros:** - About 30 g of protein per carton with roughly 1 g of sugar - Shelf-stable and needs no mixing - Budget price tier when bought by the case **Cons:** - Sweetened with sucralose and acesulfame potassium, which some nursing parents prefer to limit - Dairy-based, so not an option on a dairy-free diet - No sport certification we could confirm [Check price on Amazon](https://www.amazon.com/dp/B07MJL8NXR?tag=sktiger-20&linkCode=ll1) ### 6. Orgain Organic Protein Plant-Based Protein Powder **Award:** Best Budget Plant | **Type:** Organic pea, brown rice and chia blend - **Protein per serving:** 21 g per 2 scoops - **Calories:** About 150 - **Third-party testing:** USDA Organic; no sport certification confirmed - **Best for:** Dairy-free on a budget One of the top-selling protein powders on Amazon. Per the label at the time of writing, two scoops (about 46 g) give 21 g of protein from organic pea, brown rice and chia seed in roughly 150 calories, with under 1 g of sugar and a few grams of fiber depending on flavor. It is USDA Organic and dairy-free, sweetened with organic erythritol and stevia, and sold in large tubs that keep the cost per serving low. **Bottom line:** The low-cost dairy-free option, as long as sugar alcohols agree with you and you check the brand's testing. **Pros:** - Budget price tier and easy to find, including in warehouse-club sizes - Dairy-free and USDA Organic - Some fiber, which helps with postpartum constipation **Cons:** - Erythritol can cause gas or loose stools in some people - Plant protein with no sport certification we could confirm; ask Orgain for current heavy-metal results - 21 g of protein needs two scoops [Check price on Amazon](https://www.amazon.com/dp/B00J074W7Q?tag=sktiger-20&linkCode=ll1) ### 7.

Per the label, two scoops (about 30 g) give roughly 25 g of protein in about 120 calories, with around 2 g of naturally occurring milk sugar and no sweetener at all. Blend it into oats or a smoothie and you control exactly what goes in. **Bottom line:** The value pick for parents who blend their own shakes and want nothing on the label but protein. **Pros:** - One ingredient and no sweetener - Budget price tier per gram of protein - About 25 g of protein per serving **Cons:** - No NSF or Informed certification we could confirm; ask for batch results - Bland and slightly chalky on its own - Concentrate contains more lactose than an isolate [Check price on Amazon](https://www.amazon.com/dp/B00XIKPUK4?tag=sktiger-20&linkCode=ll1) ## 3. How Much Protein Do You Need While Breastfeeding? The Institute of Medicine's Dietary Reference Intakes set the protein RDA for lactation at 1.1 g per kilogram of body weight per day, about 71 g for a reference woman. That is the same figure as late pregnancy and roughly 25 g a day more than the 46 g, or 0.8 g per kilogram, recommended for adult women who are not pregnant or nursing. The increase covers the protein that goes into breast milk, which works out to several grams a day for a baby who is exclusively breastfed. The research base for lactation is thinner than for pregnancy, and the RDA is a floor for meeting basic needs rather than an optimum. If you are also training, recovering from a cesarean birth or trying to lose weight gradually, a target somewhere between 1.1 and 1.3 g per kilogram is a reasonable conversation to have with a dietitian. For a 70 kg woman, that is roughly 77-91 g a day. Our [protein calculator](https://www.best-proteinpowder.com/protein-calculator/) will give you a personal starting figure. Most of that should come from meals. Eggs, Greek yogurt, milk, fish, chicken, beans, lentils and tofu all bring other nutrients lactation needs, such as iodine, iron, choline and omega-3 fats. Fish is particularly useful for DHA, and the FDA and EPA advise choosing two to three servings a week of lower-mercury fish while breastfeeding. A protein shake supplies none of that unless it is fortified. A powder earns its place in the gaps. The first weeks with a newborn are when meals disappear: you eat crackers standing up, forget lunch entirely, and realize at 4 p.m. that you have had coffee and a banana. A shake that delivers 20-30 g of protein in thirty seconds is an easy way to keep your intake from collapsing during that stretch. Our explainer on [how much protein you need](https://www.best-proteinpowder.com/how-much-protein-do-i-need/) covers the per-kilogram math for every life stage. > **Lactation by the Numbers** > > - **71 g**: Protein RDA per day (IOM) > - **+330**: Extra calories per day, months 0-6 > - **+400**: Extra calories per day, months 7-12 > - **550 mg**: Choline Adequate Intake ## 4. Calories, Hunger and Postpartum Weight Making milk takes energy. The US Dietary Guidelines, based on the IOM's estimates, put the extra need at about 330 calories a day in the first six months of exclusive breastfeeding and about 400 a day in the second six months, after allowing for the energy that comes from fat stored during pregnancy. Many parents feel this as sudden, intense hunger, especially during night feeds. This is where the choice between a protein powder and a meal shake matters. A scoop of whey or pea protein adds 100-150 calories, which is a useful snack but not much against a 330-400 calorie increase when meals are already being skipped. Huel Black Edition, at about 400 calories with 40 g of protein, fat, fiber and vitamins, can genuinely stand in for a missed meal. A plain powder blended with milk, oats, a banana and peanut butter does the same job for less money; our [meal replacement shake](https://www.best-proteinpowder.com/best-meal-replacement-shake/) guide covers both approaches. Many parents also want to lose pregnancy weight, and breastfeeding can help a little. The common advice from lactation experts is to go slowly: gradual loss over months is compatible with a healthy milk supply, while crash diets and very low calorie intakes are discouraged, especially in the first weeks while supply is establishing. A high-protein snack can help with fullness when you are eating a little less, but it should not become a replacement for real meals. > **THE RULE OF THUMB** > > **Short on protein? Add a scoop. Short on meals? Add a meal shake.** > > A plain protein powder fills a protein gap in a day that still has meals. If you are missing breakfast and lunch altogether, you need calories, fat and fiber as well, and a 400-calorie meal shake or a blended homemade smoothie is the better tool. Thirst often rises with hunger. There is no need to force fluids beyond thirst, but mixing your shake with milk or water and keeping a bottle within reach during feeds is an easy habit that covers both at once. ## 5. Fenugreek and Lactation Add-Ins: What the Evidence Says Search for lactation protein and you will find powders, cookies and shakes blended with fenugreek, brewer's yeast, oats, flaxseed, fennel, blessed thistle, moringa, shatavari or goat's rue, all promising more milk. The evidence behind them is much weaker than the marketing suggests, and none of our picks contain them. ### Fenugreek Fenugreek is the most popular herbal galactagogue and the most studied, but the studies are small, short and often poorly controlled. Reviews, including a 2020 Cochrane review of oral galactagogues, found that some trials reported modest increases in milk volume but rated the certainty of the evidence as low, with very different products, doses and outcomes across studies. The Academy of Breastfeeding Medicine's protocol on galactagogues does not recommend any herb or drug as a routine first step, because evidence is limited and the root cause of low supply usually lies elsewhere. Fenugreek also has known side effects. The NIH's LactMed database lists digestive upset and diarrhea in mothers and sometimes infants, a maple-syrup smell in sweat and urine, and possible lowering of blood sugar, which matters if you take diabetes medication. Because fenugreek is a legume, people allergic to peanuts or chickpeas may react to it. It is not appropriate during pregnancy, so lactation products should not be used before the birth. ### Other lactation herbs and foods Oats, brewer's yeast and flaxseed are foods, and eating them is harmless, but there is little controlled evidence that they raise supply. Moringa has a few small trials with mixed results. Blessed thistle, fennel, shatavari and goat's rue have very little human data on effectiveness or safety for the baby. Combination blends make it impossible to know the dose of each ingredient. If you want to try a galactagogue, do it deliberately, one at a time and with a lactation consultant, not as a hidden ingredient in a daily protein shake. The most effective ways to protect supply are not supplements at all: frequent, effective milk removal, a good latch, and enough calories and fluids. If you are worried about supply, an IBCLC can assess feeding and pumping and find the real cause, which is far more useful than a fenugreek-laced powder. ## 6. Third-Party Testing and What Passes Into Milk Most of what you eat or drink reaches breast milk in some amount, which is one reason to be choosy about supplements while nursing. Protein itself is not the concern: whey and pea proteins are digested into amino acids like any other food. The concerns are contaminants, stimulants and unstudied additives. Lead and other heavy metals are the main contaminant issue. Independent testing, including Consumer Reports' protein powder testing published in 2025, has found that plant-based powders generally carry more lead than dairy-based ones, and that results vary between brands and batches. Lead can pass into breast milk, so lowering avoidable exposure is a sensible goal. Our guide to [protein powder without heavy metals](https://www.best-proteinpowder.com/best-protein-powder-without-heavy-metals/) explains how these tests work and which programs to trust. NSF Certified for Sport and Informed Choice were designed to catch banned substances in sport, and NSF Certified for Sport also screens for contaminants and checks label claims. None of these programs evaluates a product specifically for breastfeeding, but they are the best routine evidence that someone outside the company has checked what is inside. For products without a seal, email the brand and ask for a certificate of analysis for your batch, with lead, cadmium, arsenic and mercury results. Caffeine deserves a mention. The CDC notes that moderate caffeine, up to about 300 mg a day, is generally not harmful for most breastfed infants, though young or premature babies clear it more slowly. Coffee-flavored and energy proteins can add caffeine you are not counting, so choose a protein with no stimulants and keep your caffeine where you can see it. Our explainer on [whether protein powder is safe](https://www.best-proteinpowder.com/is-protein-powder-safe/) covers the regulatory side, including why supplements are not approved before sale. ## 7. Sweeteners, Dairy and Other Label Details Sweeteners are the label question nursing parents ask about most. Studies have detected small amounts of sucralose and acesulfame potassium in breast milk after mothers consumed them, which is not surprising for compounds that circulate in the blood. The FDA considers these sweeteners safe at normal intakes, and there is no established evidence of harm to infants from typical maternal use, but research on long-term effects in babies is limited. If you would rather avoid them, it is easy. Naked Whey has no sweetener at all, Truvani uses only monk fruit, and Ritual describes its pregnancy shake as free of stevia and sugar alcohols. Premier Protein uses sucralose and acesulfame potassium, and Orgain uses erythritol and stevia. Sugar alcohols such as erythritol do not pose a known risk to the baby, but they can cause gas and bloating in some adults, which you will not welcome alongside postpartum digestion. ### When the baby reacts to dairy A small proportion of breastfed babies react to cow's milk protein that passes through breast milk, with symptoms such as blood in the stool, eczema or significant fussiness. If your pediatrician suspects this and suggests you remove dairy from your own diet, that includes whey and casein powders. Ritual, Huel and Orgain are dairy-free. Do not cut dairy on a hunch, though; get a diagnosis, because an unnecessary elimination diet makes it harder to eat well. Fiber is the last detail worth checking. Postpartum constipation is common, especially after a cesarean birth or with iron supplements. Most protein powders have little fiber; Orgain and Huel have more. Whichever you choose, adding fruit, oats or chia to the shaker helps. Our [protein powder for a sensitive stomach](https://www.best-proteinpowder.com/best-protein-powder-for-sensitive-stomach/) guide covers formulas that are gentlest on digestion. ## 8. How to Fit Protein Into Life With a Newborn The best protein powder is the one you actually drink. In the first weeks, that usually means something that needs no thought. Shelf-stable cartons such as Premier Protein can sit beside the bed, in the diaper bag and in the car. A shaker bottle pre-loaded with powder, ready for water, takes the measuring out of a 3 a.m. feed. Breakfast is the easiest meal to rescue. A smoothie made with a scoop of protein, frozen fruit, oats and milk or yogurt takes two minutes and can be drunk with one hand while feeding. Making two and keeping one in the fridge covers the mid-morning slump too. One serving a day is enough for most people who use a powder at all. Two can be reasonable during a short, hectic spell, but if shakes are replacing most of your meals for weeks, a dietitian can help you build a more balanced routine. Keep taking any prenatal or postnatal vitamin your doctor recommended, and check that a fortified meal shake such as Huel does not double up on nutrients with upper limits, such as vitamin A. Partners and visitors can help here. Asking someone to make your shake, refill your water and bring a proper snack every feed is a perfectly reasonable request in the first weeks. ## 9. When to Talk to a Lactation Consultant or Doctor Protein powder is a convenience, not a treatment. If you are worried about milk supply, the most useful step is an assessment by an International Board Certified Lactation Consultant, who can look at latch, feeding frequency, pumping and your baby's weight gain. Low supply usually has a mechanical or medical cause that a supplement will not fix. Talk to your doctor before starting any supplement if you take prescription medication, have diabetes, thyroid disease, kidney disease or food allergies, or had a complicated birth. Postpartum thyroid problems, anemia and retained placental tissue can all affect supply and energy, and all need medical care. Check with your pediatrician if your baby shows signs of a reaction after you start a new product, such as unusual fussiness, rash or changes in stool. Stopping the new product and watching for improvement is a reasonable first step while you get advice. If you are planning ahead, our guide to the [best protein powder for pregnancy](https://www.best-proteinpowder.com/best-protein-powder-for-pregnancy/) covers protein needs by trimester, and the same testing and label rules apply. Once you finish breastfeeding, any of the everyday picks in our main roundups will do. ## 10. Common Mistakes to Avoid ### Buying a lactation blend for supply Fenugreek and herb-packed lactation powders cost more and have weak evidence behind them, along with side effects such as digestive upset and a maple-syrup odor. If supply is the worry, see an IBCLC lactation consultant first. Protect supply with frequent, effective feeding or pumping, and pick a plain protein for nutrition. ### Treating a protein shake as a meal A 120-calorie scoop of protein does not cover the 330-400 extra calories breastfeeding needs, let alone a skipped lunch. If you are missing meals, choose a meal shake such as Huel or blend your powder with milk, oats, fruit and nut butter so it actually feeds you. ### Crash dieting to lose baby weight Very low calorie diets are discouraged while breastfeeding, especially in the early weeks while supply is establishing. Slow, steady loss over months is the usual advice. A high-protein snack can help with hunger while you eat a little less, but it should not replace meals. ### Ignoring caffeine in flavored proteins Coffee-flavored and energy protein powders can contain caffeine or green tea extract on top of your morning coffee. The CDC suggests keeping caffeine to about 300 mg a day while nursing, less with a newborn or premature baby. Choose a protein with no stimulants so your caffeine stays countable. ### Cutting dairy without a diagnosis Removing whey and all dairy because a baby is fussy can make your own diet harder for no benefit. Cow's milk protein allergy in breastfed babies is real but uncommon. Talk to your pediatrician first, and switch to a dairy-free powder only if an elimination diet is actually recommended. ## 11. Frequently Asked Questions ### Is it safe to drink protein shakes while breastfeeding? For most nursing parents, a plain, third-party tested protein powder is considered fine, but check with your doctor, especially if you take medication. The protein itself is ordinary food. The things to avoid are contaminants such as lead, stimulants like caffeine and green tea extract, and unstudied herbal blends. Choose a short label with independent testing and keep it to about one serving a day. ### How much protein do I need while breastfeeding? The Institute of Medicine sets the lactation RDA at 1.1 g of protein per kilogram of body weight, about 71 g a day for a reference woman, compared with about 46 g for women who are not pregnant or nursing. Some parents, especially those who are active or recovering from a cesarean birth, may benefit from a little more. A dietitian can set a personal target. ### Does protein powder increase milk supply? No. There is no good evidence that protein powder raises milk supply in well-nourished parents. Supply depends mainly on frequent, effective milk removal. Eating enough calories and protein supports your health and energy while you nurse, but a shake is not a galactagogue. If you are worried about supply, an IBCLC lactation consultant can find the cause. ### Does fenugreek actually work for breast milk? The evidence is weak. Small trials report modest increases in milk volume, but a 2020 Cochrane review rated the overall certainty as low, and the Academy of Breastfeeding Medicine does not recommend routine use of galactagogues. Fenugreek can cause digestive upset, a maple-syrup body odor and lower blood sugar, and it may trigger reactions in people allergic to peanuts or chickpeas. ### What is the best protein powder for breastfeeding moms? Our top pick is Ritual's Pregnancy and Postpartum shake, which gives 20 g of pea protein and 250 mg of choline per serving per its label and contains no lactation herbs. Huel Black Edition is better if you need calories as well as protein, Thorne Whey Isolate is the best certified dairy option, and Premier Protein is the easiest shelf-stable shake for night feeds. ### Can artificial sweeteners in protein shakes pass into breast milk? Small amounts can. Studies have detected sucralose and acesulfame potassium in breast milk after mothers consumed them. The FDA considers these sweeteners safe at normal intakes and no harm to infants has been established, but long-term research is limited. If you prefer to avoid them, choose an unsweetened powder like Naked Whey or one sweetened with monk fruit, such as Truvani. ### Can I use protein shakes to lose weight while breastfeeding? They can help as a filling, high-protein snack while you eat slightly less, but go slowly. Lactation experts generally advise gradual weight loss over months and discourage crash diets, particularly in the first weeks while supply is establishing. Do not replace several meals a day with shakes without medical guidance, and keep total calories high enough that you feel well. ## Related Protein Guides for Women - [Best Protein Powder for Pregnancy](https://www.best-proteinpowder.com/best-protein-powder-for-pregnancy/): Protein by trimester, third-party testing and the ingredients to avoid. - [Best Meal Replacement Shake](https://www.best-proteinpowder.com/best-meal-replacement-shake/): Calories, fiber and cost per meal for the days you cannot sit down to eat. - [Best Protein Powder for Women](https://www.best-proteinpowder.com/best-protein-powder-for-women/): Everyday picks for women, from lean isolates to certified plant blends. ## The Bottom Line While breastfeeding, the right protein powder is plain, tested and easy to drink with one hand.
