Introduction
If you have ever spent a late night staring at the ounce markers on a baby bottle or looking down at your pump parts, wondering if you are doing enough, you are not alone. That feeling of uncertainty—wondering if your body is producing what your baby needs—is a weight that many breastfeeding and pumping parents carry. We know how much pressure you are under. At Milky Mama, we believe that while breastfeeding is a natural process, it doesn’t always come naturally, and every drop counts.
When searching for ways to support your production, you may have heard whispers about certain "superfoods." One of the most frequently discussed ingredients in lactation circles is barley. But can barley increase milk supply, or is it just an old wives' tale? The short answer is that barley is one of the most respected and evidence-based galactagogues (milk-boosting substances) available in nature. It contains specific compounds that interact with your hormones to help your body do what it was created to do.
In this comprehensive guide, we are going to dive deep into the relationship between barley and breastfeeding. We will explore the science behind beta-glucan, the difference between barley malt and beer, and practical, delicious ways to incorporate this grain into your diet. We will also touch on other lifestyle factors and supportive products that can help you feel empowered on your journey. By the end of this post, you will have a clear understanding of how barley works and how you can use it to support your breastfeeding goals.
The Science: How Barley Supports Lactation
To understand if barley can increase milk supply, we have to look at what is happening inside the body. Breastfeeding is a complex hormonal dance, primarily driven by two hormones: prolactin and oxytocin. Prolactin is often called the "milk-making" hormone because it tells your mammary glands to produce milk. Oxytocin is the "milk-releasing" hormone, responsible for the let-down reflex.
Barley is unique because it is exceptionally rich in a type of complex sugar called beta-glucan.
The Power of Beta-Glucan
Beta-glucan is a polysaccharide (a type of dietary fiber) that has been shown in various studies to increase prolactin levels in both humans and animals. When you consume barley, the beta-glucan triggers the pituitary gland to release more prolactin. Because prolactin is the primary driver of milk synthesis, an increase in this hormone can lead to a more robust milk supply for many parents.
Research published in databases like LactMed suggests that barley is a purported galactagogue used by mothers in many different cultures for centuries. In a controlled study involving mothers of preterm infants, those who consumed a barley-malt-based supplement saw a significant increase in milk volume compared to those who did not. By day 14 of the study, the mothers using the barley-based support were producing an average of 95 mL per session, compared to 62.5 mL in the control group. This is a substantial difference that can mean the world to a parent trying to build a freezer stash or simply keep up with a growing baby’s appetite.
Barley as a Source of Tryptophan
Beyond beta-glucan, barley also contains tryptophan. Tryptophan is an essential amino acid that serves as a precursor to serotonin. Serotonin isn't just a "feel-good" neurotransmitter; it actually plays a role in the lactation process by supporting the hormones that keep milk flowing. When your serotonin levels are balanced, it may be easier for your body to handle the stresses of new parenthood, which indirectly supports your let-down reflex.
Barley Malt vs. Beer: Clearing Up the Myth
You may have heard a well-meaning relative suggest that "drinking a dark beer" is the secret to a high milk supply. While this advice is rooted in the fact that beer often contains barley and barley malt, it is a bit of a misconception.
Why Beer Isn't the Best Choice
While the barley in beer can technically stimulate prolactin, the alcohol in beer can actually work against you. Alcohol is known to inhibit the release of oxytocin. This means that even if your body is making milk, the alcohol can make it harder for that milk to actually "let down" and leave the breast.
Furthermore, even small amounts of alcohol can temporarily change the flavor of your milk, which might cause some babies to nurse less frequently. Since breastfeeding is a "demand and supply" system, less frequent nursing can lead to a drop in supply over time. At Milky Mama, we want you to have the most effective tools possible, and there are much better ways to get the benefits of barley without the potential downsides of alcohol.
The Benefits of Barley Malt
Barley malt is created when barley grains are germinated and then dried. This process activates enzymes that make the nutrients more bioavailable. Barley malt is a concentrated source of that milk-boosting beta-glucan. It has a sweet, nutty flavor and can be found in syrups or powders. This is a much more direct and effective way to harness the power of barley for your milk supply.
Different Ways to Use Barley in Your Diet
If you are wondering how to practically incorporate this grain into your busy life, the good news is that barley is incredibly versatile. Whether you prefer savory meals or sweet treats, there is a way to make barley work for you.
1. Whole Barley in Soups and Stews
One of the easiest ways to eat more barley is to swap it for rice or pasta in your favorite soup recipes. Pearled barley has a wonderful, chewy texture that holds up well in slow cookers.
- Practical Scenario: Imagine a busy Monday where you barely have time to sit down. You can toss some vegetable broth, carrots, celery, lean protein, and a half-cup of pearled barley into a slow cooker in the morning. By dinner time, you have a nourishing, galactagogue-rich meal that supports your supply while you sleep.
2. Barley Water
In many cultures, "barley water" is a traditional drink given to nursing mothers. It is hydrating and nutrient-dense.
- How to make it: Boil about a half-cup of barley in four cups of water for about 20 minutes. Strain the liquid and add a splash of lemon or a bit of honey for flavor. You can keep this in the fridge and sip on it throughout the day. If you are looking for even more flavor and hydration support, you might also enjoy our Lactation LeMOOnade™ or Milky Melon™, which are designed to keep you hydrated while supporting your journey.
3. Barley Flakes for Breakfast
Just like oatmeal, barley can be processed into flakes. You can use these just like rolled oats to make a warm breakfast porridge. Since oats also contain beta-glucan, mixing oats and barley flakes together gives you a "double hit" of lactogenic power to start your day.
4. Baking with Barley Flour
You can substitute a portion of all-purpose flour with barley flour in recipes for muffins, pancakes, or bread. This adds a nutty depth to your baked goods and increases the fiber and galactagogue content of your snacks.
Other Galactagogues That Complement Barley
While barley is fantastic, it often works best when part of a varied, nutrient-dense diet. Many of our favorite lactation snacks combine several power ingredients to provide comprehensive support.
The Role of Oats
Oats are perhaps the most famous breastfeeding food, and for good reason. Like barley, they are high in beta-glucan. We love incorporating oats into our Oatmeal Chocolate Chip Cookies and Oatmeal Cookies. They provide a steady source of energy, which is vital when you are up for those middle-of-the-night feeding sessions.
Leafy Greens
Dark, leafy greens like spinach, kale, and alfalfa are packed with phytoestrogens. These plant-based compounds can have a positive effect on milk production. If you find it hard to eat enough salads during the day, our Lady Leche™ herbal supplement contains alfalfa to help you get those benefits in a convenient form.
Brewer's Yeast
Brewer's yeast is a nutritional powerhouse rich in B vitamins, iron, and protein. It has been used for generations to support milk supply. You will often find it in our bestseller, the Emergency Brownies, which are a favorite for moms who need a little extra boost.
Seeds and Nuts
Almonds, flaxseeds, and chia seeds are excellent sources of healthy fats and protein. These nutrients are essential for the quality of your milk. For a delicious way to get these into your diet, you might try our Peanut Butter Chocolate Chip Cookies or Peanut Butter Cookies.

Beyond Food: The Fundamentals of Milk Supply
While we love the power of barley and other galactagogues, we always want to remind our Milky Mama family that food is just one piece of the puzzle. Breastfeeding is a biological system that relies heavily on physical cues.
Demand and Supply
The most important factor in milk production is the frequent and effective removal of milk. When your baby nurses or you pump, it sends a signal to your brain to make more milk. If you are struggling with supply, try to increase the frequency of your sessions.
- Pumping Tip: If you are a pumping parent, ensure your flanges are the correct size. Using the wrong size can lead to ineffective milk removal and discomfort. For those looking to maximize their output during sessions, our Pumping Queen™ or Pump Hero™ supplements are formulated specifically with the needs of pumping moms in mind.
Hydration and Calories
Your body needs extra fuel to create milk. It is generally recommended to consume an additional 300 to 500 calories per day while breastfeeding. Staying hydrated is also crucial. While you don't need to force-feed yourself water, drinking to thirst is a good rule of thumb. If you find plain water boring, our Pumpin Punch™ or the Drink Sampler can make staying hydrated feel like a treat.
Stress and Rest
We know, telling a new parent to "just relax and sleep" can feel like a joke. However, high levels of cortisol (the stress hormone) can interfere with your let-down reflex. Taking even five minutes for deep breathing or a warm shower can help your oxytocin flow. Remember, you are doing an amazing job, and your well-being matters just as much as your baby’s.
Things That Can Decrease Your Supply
Just as there are foods that help, there are a few things that can sometimes hinder your production. It’s good to be aware of these so you can make informed choices.
- Certain Herbs in Large Quantities: While a little parsley on your pasta is fine, consuming very large amounts of peppermint, sage, or parsley has been known to decrease supply in some people.
- Decongestants: Medications containing pseudoephedrine are designed to dry up mucus, but they can also dry up milk supply. Always talk to your healthcare provider before taking over-the-counter cold medications.
- Hormonal Contraceptives: For some parents, birth control containing estrogen can cause a dip in supply. Progestin-only options (often called the "mini-pill") are usually preferred for breastfeeding families.
- Chasteberry: Often found in hormone-balancing supplements, chasteberry can inhibit prolactin, which is the opposite of what we want when trying to increase supply.
Why Representation and Support Matter
At Milky Mama, we are more than just a company that makes lactation treats; we are a community. We believe that representation matters, especially for Black breastfeeding moms who have historically faced higher barriers to support and resources.
Breastfeeding can be a vulnerable time, and having a village that understands your unique challenges—whether it's navigating workplace pumping or dealing with cultural pressures—is vital. That is why we offer virtual lactation consultations and online breastfeeding classes, including our Breastfeeding 101 class. You don't have to figure this out alone.
Practical Steps to Take Today
If you are ready to see if barley can increase milk supply for you, here is a simple action plan:
- Audit your pantry: Add pearled barley to your grocery list.
- Swap your snacks: Replace processed snacks with nutrient-dense options like our Fruit Sampler or Salted Caramel Cookies.
- Check your hydration: Keep a bottle of water or a lactation drink nearby every time you sit down to nurse or pump.
- Connect with others: Join The Official Milky Mama Lactation Support Group on Facebook to share tips and find encouragement from parents who have been exactly where you are.
Summary of the Benefits of Barley
To recap, barley is a powerhouse for breastfeeding parents because:
- It is the richest dietary source of beta-glucan, which naturally boosts prolactin.
- It contains tryptophan, which supports the hormonal balance needed for lactation.
- It provides sustained energy through complex carbohydrates.
- It is versatile and affordable, making it easy to add to many different meals.
While it is not a "magic pill" (nothing is!), it is a scientifically-backed tool that can support your body’s natural ability to produce milk. When combined with frequent milk removal, proper hydration, and a supportive community, barley can be a game-changer for your breastfeeding journey.
FAQ
1. How soon will I see a difference after eating barley?
Every body is different. Some parents notice a change in their "fullness" or pumping output within 24 to 48 hours of adding galactagogues like barley to their diet, while for others, it may take a week of consistent consumption. Consistency is key!
2. Can I eat too much barley?
Barley is a healthy whole grain, but like anything, it should be part of a balanced diet. Because it is high in fiber, suddenly increasing your intake significantly might cause some temporary bloating or gas. It’s best to increase your intake gradually and drink plenty of water.
3. Is barley safe if I have a gluten intolerance?
No. Barley contains gluten. If you have celiac disease or a gluten sensitivity, you should avoid barley. Instead, focus on gluten-free galactagogues like quinoa, millet, or our gluten-friendly supplement options like Milk Goddess™ or Milky Maiden™.
4. Do I need to eat barley every day to keep my supply up?
Not necessarily. Once your supply is established and meets your baby's needs, you might find you don't need to be as diligent. However, many parents find that keeping barley and other milk-boosting foods in their regular rotation helps them maintain consistency, especially during growth spurts or stressful times.
Conclusion
The journey of nourishing your baby is one of the most selfless and challenging things you will ever do. Whether you are breastfeeding, pumping, or a mix of both, please know that you are doing an amazing job. Your worth as a parent is not measured in ounces, but we understand the desire to provide as much as you can.
