If you have ever worried about your milk supply, you are certainly not alone. Many nursing parents experience moments of doubt, wondering if their bodies are producing enough to keep their little ones satisfied and growing. It is a common concern that often leads to a search for natural ways to provide a little extra support. One of the most traditional suggestions you might hear from a fellow mom or a grandmother is to try eating more barley.
Barley is a versatile cereal grain that has been used for centuries in various cultures to support nursing mothers. At Milky Mama, we believe that education and nutrition are key pillars of a successful breastfeeding journey, and our lactation snacks are designed to fit into that kind of supportive routine. We want to help you understand the "why" and "how" behind these traditional remedies so you can make informed choices for your wellness. In this article, we will explore the science behind barley, how it may support your lactation goals, and simple ways to incorporate it into your daily routine.
While every breastfeeding journey is unique, understanding the role of nutrition can empower you to feel more confident in your body’s abilities. We are here to walk you through the evidence and provide practical tips for using this ancient grain. Barley may be a helpful tool in your lactation toolkit when paired with proper breastfeeding techniques and support.
Barley is one of the oldest cultivated grains in the world, belonging to the grass family. It is a hardy cereal grain with a nutty flavor and a chewy consistency. In the United States, you most often see it in the form of pearled barley, which has had its outer husk and bran layers removed. While this makes it cook faster, some of the fiber is lost in the process. Hulled barley, on the other hand, is considered a whole grain because only the inedible outer shell is removed.
This grain is packed with essential nutrients that are beneficial for anyone, but they are particularly supportive for nursing parents. Barley is a rich source of dietary fiber, especially a type of soluble fiber called beta-glucan. It also contains important minerals like selenium, copper, manganese, and phosphorus. When you are breastfeeding, your body requires extra nutrients to produce high-quality milk while maintaining your own energy levels.
Historically, barley has been used in everything from soups and stews to traditional beverages. It is a staple in many diets because it is affordable, filling, and provides sustained energy. For breastfeeding families, it is often categorized as a galactagogue. A galactagogue is a substance—typically a food, herb, or medication—that is believed to help increase or maintain milk production.
The primary reason barley is linked to milk supply is its potential effect on prolactin. Prolactin is often called the "milk-making hormone." It is produced by the pituitary gland and tells the mammary glands in your breasts to produce milk. When you nurse or pump, your prolactin levels naturally rise to ensure there is milk ready for the next feeding.
Barley contains specific polysaccharides, which are complex carbohydrates. Research suggests that these polysaccharides, particularly the beta-glucans found in barley, may stimulate the release of prolactin from the pituitary gland. By potentially increasing the levels of this hormone in your system, barley can help signal your body to maintain or increase its milk output.
It is important to remember that while barley may help support your levels, the most effective way to produce milk is through the frequent and effective removal of milk. Think of barley as a supportive partner to your regular nursing or pumping schedule. It provides the nutritional building blocks and the hormonal nudge that many moms find helpful during growth spurts or times of stress.
Key Takeaway: Barley contains polysaccharides that may naturally boost prolactin levels, the hormone responsible for signaling your body to make more milk.
If you have spent time researching lactation-supportive foods, you have likely heard of beta-glucan. This is a type of soluble fiber found in high concentrations in both barley and oats. Beta-glucan is well-known in the health community for its ability to support heart health and manage cholesterol levels. However, in the world of breastfeeding, it is prized for its lactogenic properties.
When you consume foods rich in beta-glucan, it interacts with your digestive system in a way that may influence your endocrine system. For many moms, this translates to a more robust let-down reflex or a feeling of "fullness" in the breasts. The let-down reflex is the process where the small muscles in the breast contract to push milk into the ducts.
In addition to its potential hormonal benefits, beta-glucan is excellent for your digestive health. Many new parents struggle with digestive regularity after birth. The high fiber content in barley helps keep things moving, which can improve your overall sense of well-being. When you feel better physically, your body can focus more energy on the demanding task of lactation.
You might notice that many lactation-specific products or traditional recipes specifically mention "malted" barley. Malting is a process where the grain is soaked in water and allowed to germinate (sprout) before being dried with hot air. This process activates enzymes within the grain and changes its nutritional profile.
Malted barley is often used in the production of cereal beverages and certain baked goods. Some studies have indicated that the malting process might make the polysaccharides more accessible to the body, potentially increasing the galactagogue effect. This is one reason why barley malt syrup is often used as a sweetener in lactation cookies or treats.
At Milky Mama, we focus on using high-quality ingredients that serve a purpose. While we often use oats as a primary grain in our treats, such as our popular Emergency Brownies, we recognize the similar power that grains like barley hold. Both contain the fiber and nutrients necessary to help you feel nourished while you navigate the demands of a new baby.
One of the oldest recipes for breastfeeding support is barley water. This simple drink has been used for generations in the United Kingdom, Asia, and the Middle East. It is a hydrating, nutritious beverage that is very easy to make at home. Since staying hydrated is one of the most important factors in maintaining milk supply, barley water offers a double benefit.
To make traditional barley water, you simply simmer pearled barley in a large pot of water for about 20 to 30 minutes. Once the water has taken on a cloudy appearance and the grains are soft, you strain the liquid into a pitcher. You can drink it plain, but many people prefer to add a squeeze of lemon or a small amount of honey for flavor.
The "spent" barley grains don't have to go to waste, either. You can add the cooked barley to a salad or a bowl of soup. The liquid itself is thought to be rich in the beta-glucans that have leached out of the grain during the simmering process. It is a gentle, soothing drink that many moms find helpful during those long middle-of-the-night nursing sessions.
There is an old wives' tale that drinking a dark beer can help increase milk supply. This myth actually has its roots in barley. Historically, beer was made with high amounts of barley malt and was much lower in alcohol than the craft beers of today. People noticed that nursing parents who drank these "small beers" seemed to have a better milk supply.
However, modern science has shown us that alcohol can actually have the opposite effect. Alcohol can inhibit the let-down reflex and may even slightly decrease milk production if consumed in excess. It also passes into the breast milk, which is not ideal for the baby. The benefit that people were seeing in the past came from the barley, not the alcohol.
If you want the benefits of the grain without the risks of alcohol, sticking to barley water, barley tea, or non-alcoholic malt beverages is a much better choice. These options give you the polysaccharides and nutrients your body needs to support prolactin without the dehydrating effects of alcohol.
Beyond its potential to help with milk supply, barley is a nutritional powerhouse. When you are breastfeeding, your body is working overtime. You need a steady supply of complex carbohydrates to keep your energy up and a variety of vitamins and minerals to support your baby’s growth.
Integrating barley into your diet is an excellent way to ensure you are getting a broad spectrum of nutrients. It is a low-glycemic grain, meaning it provides a slow release of energy rather than a quick spike in blood sugar. This can help prevent the "crashes" that often come with a lack of sleep and a busy schedule.
If you aren't used to cooking with barley, it can feel a bit intimidating. The good news is that it is very similar to cooking rice or quinoa. Pearled barley usually takes about 25 to 30 minutes to cook, while hulled barley may take up to an hour. You can cook a large batch at the beginning of the week and keep it in the fridge to add to various meals.
One of the easiest ways to eat barley is in a hearty vegetable soup. The grain acts as a natural thickener, giving the soup a creamy texture without the need for dairy. You can also use it as a base for a grain bowl. Top it with some roasted vegetables, a source of protein like chicken or chickpeas, and a simple lemon tahini dressing.
For breakfast, try a "barley bowl" instead of your usual oatmeal. Top it with fresh berries, a sprinkle of flaxseed, and a splash of almond milk. Since we know that variety is the spice of life—and breastfeeding—switching up your grains can help you stay excited about your healthy eating habits. If you want more everyday food ideas, our lactation drink mixes can be an easy way to build a supportive routine.
For the vast majority of breastfeeding parents, barley is a safe and healthy addition to their diet. It is a common food staple around the world. However, there is one major exception: barley contains gluten. If you have celiac disease or a non-celiac gluten sensitivity, you should avoid barley completely.
Consuming barley if you have a gluten intolerance can cause inflammation in the gut, which can lead to nutrient malabsorption and other health issues. If you need to avoid gluten but want the benefits of galactagogues, there are many gluten-free options available. Grains like quinoa and certified gluten-free oats can offer similar nutritional support without the risk of an adverse reaction.
As with any change to your diet or the introduction of supplements, it is always a good idea to listen to your body. If you notice any digestive upset or if your baby seems unusually fussy after you consume a large amount of barley, you may want to scale back. Every person’s body reacts differently to various foods, and what works wonders for one mom might not be the best fit for another.
While barley is a fantastic food, it works best when it is part of a holistic approach to breastfeeding. We always remind our community that "every drop counts," and those drops are produced most efficiently when you are well-rested (as much as possible!), hydrated, and frequently removing milk.
If you are struggling with low supply, consider adding other supportive habits alongside your barley intake. Skin-to-skin contact with your baby is a powerful way to naturally boost oxytocin and prolactin levels. Spending 20 minutes a day with your baby tucked against your chest can do wonders for your milk production and your bond.
You can also pair barley with other well-known galactagogues. Adding foods like flaxseed, brewer's yeast, and almonds to your diet can provide a synergistic effect. Many Milky Mama products, like our Lactation LeMOOnade™ or Pumping Queen™ herbal supplement, are designed to work in harmony with a nutritious diet to help you reach your breastfeeding goals.
Key Takeaway: For the best results, combine barley consumption with frequent nursing, skin-to-skin contact, and high levels of hydration.
It is worth taking a moment to discuss the biological foundation of milk production: supply and demand. Your breasts are constantly sensing how much milk is being removed. When a baby latches or a pump is used, it sends a signal to your brain to keep producing. If milk is left in the breast for long periods, your body receives a signal to slow down production.
This is why, no matter how much barley you eat, you must ensure you are nursing or pumping often enough. For most newborns, this means 8 to 12 times in a 24-hour period. If you are using barley to help increase your supply, you might find it helpful to add an extra pumping session or a "power pumping" hour to your day to really kickstart the process. Our guide on how often to pump when exclusively breastfeeding can help you plan your routine.
Barley provides the "fuel" and the hormonal support, but the "demand" is what keeps the factory running. If you are feeling overwhelmed by your pumping schedule or your baby's latch, don't hesitate to reach out for professional help. A Certified Lactation Consultant (IBCLC) can help you troubleshoot any issues and ensure that your baby is removing milk effectively through our breastfeeding help page.
Sometimes, despite our best efforts with diet and frequency, we still face challenges. It is important to know that seeking help is a sign of strength, not failure. If you are concerned that your baby is not gaining weight, if they are having fewer than six wet diapers a day, or if you are experiencing significant pain during nursing, it is time to call a professional.
A lactation consultant can perform a weighted feed to see exactly how much milk your baby is getting. They can also check for things like tongue-ties or latch issues that might be preventing your baby from stimulating your supply correctly. Your healthcare provider can also rule out any underlying medical conditions, such as thyroid issues or retained placenta, that could be impacting your milk production.
At Milky Mama, we offer virtual lactation consultations and online classes to make this support accessible from the comfort of your own home. We want you to feel empowered and supported every step of the way. You don't have to navigate these challenges alone, and our online courses can be a helpful next step if you want more structured education.
If you want to see if barley can help your milk supply, here is a simple plan to get started:
Key Takeaway: Consistency is key. Pair your barley intake with frequent milk removal and plenty of water for the best results.

For most people, barley is a very safe and healthy food to eat while nursing. However, because barley contains gluten, it is not safe for individuals with celiac disease or gluten sensitivity. If you or your baby have any known allergies to grains, it is best to consult with your doctor before adding it to your diet.
Most nursing parents notice a difference within 24 to 72 hours of consistently adding barley to their diet. However, because every body is different, some people may see results sooner, while others may need a bit more time. It is important to continue nursing or pumping frequently during this time to signal your body to produce more milk.
Yes, roasted barley tea is a very popular beverage in many cultures and is a great way to get the benefits of the grain. While the tea may have slightly lower levels of fiber than eating the whole grain, it is excellent for hydration and still contains the beneficial polysaccharides. It is a caffeine-free option that can be enjoyed hot or cold throughout the day.
No, the alcohol in beer does not increase milk supply and can actually decrease it by inhibiting your let-down reflex. The traditional belief that beer helps with lactation comes from the barley and hops used to make it, not the alcohol itself. To get the benefits without the risks, opt for barley water, barley tea, or foods containing barley malt instead.
