Introduction

If you have ever felt a surge of worry while watching your baby nurse, you are not alone. Many breastfeeding parents experience moments where they wonder if their bodies are producing enough to keep their little ones satisfied. It is a common concern that often leads to a search for natural ways to provide a little extra support for lactation. One of the most traditional suggestions you might hear from a fellow mom or a lactation professional is to try adding more barley to your diet.

Barley is a versatile cereal grain that has been used for centuries in various cultures to support nursing families. At Milky Mama, we believe that education and nutrition are the pillars of a successful breastfeeding journey. Our mission is to empower you with the knowledge you need to feel confident in your body’s abilities. We want to help you understand the "why" and "how" behind traditional remedies so you can make informed choices for your wellness. If you want a broader look at product options while you learn, our lactation supplements collection is a helpful place to start.

In this article, we will explore the science behind barley and how it may support your lactation goals. We will also cover simple, practical ways to incorporate it into your daily routine. While every breastfeeding journey is unique, understanding the role of nutrition can help you navigate challenges with a sense of control and hope. Barley may be a helpful tool in your lactation toolkit when paired with proper feeding techniques and support.

What is Barley?

Barley is one of the oldest cultivated grains in the world and belongs 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. This version has had its outer husk and bran layers removed to make it cook faster. 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. However, they are particularly supportive for nursing parents who have higher nutritional demands. 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.

Historically, barley has been used in everything from hearty soups to traditional medicinal beverages. It is a staple in many diets because it is affordable and provides sustained energy. For breastfeeding families, it is often categorized as a galactagogue. A galactagogue (pronounced gah-lak-tah-gog) is a substance—typically a food or herb—that is believed to help increase or maintain milk production.

How Barley May Support Milk Supply

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 session.

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.

Understanding Beta-Glucan

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 general health community for its ability to support heart health. 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 parents, 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 in the weeks following 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.

The Role of Malted Barley

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 before being dried. 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 clinical studies involving mothers of preterm infants have indicated that barley malt-based compositions can lead to a measurable increase in milk volume. This is because the malting process may 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-supportive treats.

Our founder, Krystal Duhaney, RN, BSN, IBCLC, understands the importance of using ingredients rooted in clinical expertise. While we often use oats as a primary grain in our treats, such as our popular Emergency Lactation 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.

Ways to Use Barley Malt

Add barley malt syrup to your morning bowl of oatmeal.
Use it as a natural sweetener in homemade lactation muffins.
Stir a spoonful into a warm cup of almond or dairy milk.
Look for it in the ingredient lists of specialty lactation snacks.

Traditional Barley Water for Lactation

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 cooked barley grains don't have to go to waste. You can add them to a salad or a bowl of soup later. 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. If you like ready-made hydration support, the lactation drink mixes collection is another option to explore.

Barley and Beer: Addressing the Myth

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 malt, 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.

Nutritional Profile of Barley

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.

Essential Minerals

Selenium: This mineral is a powerful antioxidant that helps protect your cells from damage. It also plays a role in thyroid function, which is closely linked to hormone regulation and energy levels.
Copper and Manganese: These trace minerals are essential for bone health and the production of connective tissue.
Phosphorus: Working with calcium, phosphorus is vital for maintaining strong bones and teeth. This is especially important as your body shares its calcium stores with your baby through your milk.

Energy-Boosting Carbohydrates

Barley is a low-glycemic index food. This means it provides a slow, steady release of energy into your bloodstream rather than a quick spike and crash. For an exhausted parent, this stable energy source can make a significant difference in how you feel throughout the day. "Breasts were literally created to feed human babies," and those breasts require a lot of fuel to do their job well.

How to Add Barley to Your Meal Plan

If you are not used to cooking with barley, it can feel intimidating. However, it is very similar to cooking rice or oats. Because it has a neutral, nutty flavor, it pairs well with both sweet and savory ingredients.

Savory Options

The most common way to eat barley is in soup. A classic beef or mushroom and barley soup is filling and comforting. Because barley absorbs a lot of liquid, it helps thicken soups and stews naturally. You can also use cooked barley as a base for a grain bowl. Top it with roasted vegetables, a protein like chicken or chickpeas, and a simple dressing.

Sweet Options

You can treat barley much like breakfast porridge. Cook it in milk or a dairy alternative and top it with berries, nuts, and a drizzle of maple syrup. Some people also enjoy barley tea, which is made from roasted barley grains. It has a toasted, slightly bitter flavor that is very refreshing when served cold or comforting when served hot.

Quick Barley Action Plan

Stock up: Keep a bag of pearled barley in your pantry for quick additions to meals.
Prep ahead: Cook a large batch of barley at the beginning of the week and store it in the fridge.
Hydrate: Make a pitcher of barley water once or twice a week to sip on between feedings.
Experiment: Try replacing rice or pasta with barley in your favorite recipes to boost fiber and nutrients.

Safety and Considerations

For most people, barley is a safe and healthy addition to a breastfeeding diet. However, there are a few things to keep in mind. Barley contains gluten. If you have celiac disease or a non-celiac gluten sensitivity, you should avoid barley and stick to gluten-free galactagogues like gluten-free oats or quinoa.

If you are thinking about using herbal lactation supplements that contain barley or other ingredients, it is always a good idea to chat with your healthcare provider first. Every body is different, and what works for one person might not be the best fit for another. While many of our products, like the Lady Leche™ or Pumping Queen™, are designed to support supply, they are intended to be part of a holistic approach to lactation.

This product is not intended to diagnose, treat, cure, or prevent any disease. Consult with your healthcare provider for medical advice.

The Foundation of Milk Supply

While foods like barley can provide a wonderful boost, it is important to remember the "supply and demand" nature of breastfeeding. The more milk is removed from the breast, the more milk your body will make. If you are struggling with supply, nutrition is just one piece of the puzzle.

Ensure your baby has a deep, comfortable latch. A good latch ensures that the baby is effectively removing milk, which signals your body to keep producing. If you are pumping, make sure your breast shields (flanges) are the correct size. Using the wrong size can lead to discomfort and less effective milk removal. For a deeper look at pumping technique, our guide on how to increase your milk supply when pumping can help.

Skin-to-skin contact is another powerful, non-food way to boost supply. Snuggling with your baby chest-to-chest triggers the release of oxytocin, the hormone responsible for the let-down reflex. Pairing these physical techniques with a nutrient-rich diet that includes barley can create a strong foundation for your breastfeeding journey. If you want more on that connection, read about how skin-to-skin contact increases milk supply.

When to Seek Professional Support

Sometimes, despite your best efforts and a diet full of galactagogues, you may still face challenges. This is completely normal and not a reflection of your worth as a parent. If you are concerned about your baby’s weight gain, the number of wet and dirty diapers, or if you are experiencing pain, it is time to reach out for professional help.

A Certified Lactation Consultant (IBCLC) can provide a personalized assessment of your situation. They can help you troubleshoot latch issues, create a pumping plan, and offer guidance on using supplements or specific foods like barley. We offer virtual lactation consultations to provide you with expert support from the comfort of your own home, and you can also join the Official Milky Mama Lactation Support Group on Facebook for community encouragement. Remember, "you're doing an amazing job," and asking for help is a sign of strength and dedication to your baby’s well-being. For one-on-one support, our breastfeeding help page is there when you need it.

FAQ

How long does it take for barley to work for milk supply?

Most nursing parents notice a difference within 24 to 72 hours of consistently adding barley or barley malt to their diet. However, every body is different, and the results can vary based on how often you are nursing or pumping. For the best results, try to incorporate it into your daily meals rather than just eating it occasionally. If you want guidance on supplement timing and expectations, this lactation supplements timing guide is a useful read.

Can I drink barley tea while breastfeeding?

Yes, barley tea (often called mugicha in Japan or boricha in Korea) is generally considered safe and beneficial for breastfeeding. It is caffeine-free and provides a hydrating alternative to water. It contains the same beneficial polysaccharides found in the grain, which can help support your prolactin levels throughout the day. You can also compare beverage-style options in the lactation drink mixes collection.

Is pearled barley as good as whole barley for supply?

While whole-grain (hulled) barley contains more fiber and slightly more nutrients, pearled barley still contains the essential beta-glucans needed to support milk supply. Pearled barley is much easier to find and faster to cook, making it a more practical choice for many busy parents. Both forms are excellent additions to a lactation-supportive diet.
