Introduction
Have you ever found yourself sitting on the nursery floor at 3:00 AM, scrolling through your phone, and wondering if that extra bowl of oatmeal or a specific glass of "mother’s tea" is actually doing anything for your milk supply? If you have, you’re certainly not alone. Many of us at Milky Mama have been in that exact spot—questioning our bodies, tracking every ounce, and looking for a natural way to give our supply a little boost. One of the most common questions we hear from our community is: does barley increase milk supply?
There is an old wives' tale that suggests drinking a dark beer can help "bring the milk in." While we definitely don’t recommend reaching for an alcoholic beverage to solve supply issues, there is actually a kernel of truth hidden in that old legend. The secret isn't the alcohol; it’s the barley. This humble grain has been used for centuries across various cultures as a traditional galactagogue—a substance that helps increase breast milk production.
In this post, we are going to dive deep into the science behind barley, how it interacts with your hormones, the safest ways to include it in your diet, and other evidence-based strategies to support your breastfeeding journey. Our goal is to empower you with the knowledge you need to feel confident in your body’s ability to nourish your little one. After all, breastfeeding is natural, but it doesn’t always come naturally, and having the right tools can make all the difference.
The History of Barley as a Galactagogue
Barley (Hordeum vulgare) is one of the oldest cultivated grains in human history. From ancient Egypt to traditional Chinese medicine, it has been revered not just as a staple food, but as a medicinal powerhouse. For lactating parents, barley has historically been prepared as "barley water" or included in hearty soups and stews to support recovery after birth and encourage a robust milk supply.
In many cultures, the postpartum period is treated as a time for "warming" foods. Barley, when cooked slowly, is considered a grounding, nourishing grain that provides the complex carbohydrates and minerals a new mother needs. At Milky Mama, we love looking at these traditional remedies through a modern, clinical lens. As our founder, Krystal Duhaney, RN, BSN, IBCLC, often emphasizes, combining ancestral wisdom with evidence-based lactation support is the gold standard for care.
Does Barley Increase Milk Supply? The Science
When we ask if barley increases milk supply, we have to look at a specific component found in the grain: beta-glucan.
The Role of Beta-Glucan
Beta-glucan is a type of polysaccharide (a complex sugar) found in the cell walls of barley and oats. Research suggests that beta-glucan can stimulate the secretion of prolactin, which is the primary hormone responsible for tellings your breasts to produce milk.
When you consume foods rich in beta-glucan, it may trigger a response in the pituitary gland. For many moms, an increase in prolactin levels translates to a more consistent milk supply. This is one of the reasons why barley is often considered even more potent than oats in some lactation circles—it actually contains a higher concentration of this specific polysaccharide.
Prolactin and the "Demand and Supply" Connection
It is important to remember that while galactagogues like barley can support the hormonal side of milk production, they work best when paired with frequent milk removal. Breastfeeding operates on a demand-and-supply system. The more often your baby nurses (or the more often you pump), the more signals your body receives to make more milk.
Think of barley as the "fuel" for the factory. You can have all the fuel in the world, but if the machines aren't running (milk isn't being removed), the factory won't produce. However, when you combine frequent nursing with nourishing foods like barley, you are giving your body the best possible environment to thrive.
Key Takeaway: Barley contains beta-glucan, which may help raise prolactin levels. This hormone is essential for milk production, making barley a scientifically backed food for breastfeeding support.
Barley vs. Beer: Debunking the Myth
We’ve all heard it: "Drink a Guinness, it'll help your milk!" While it’s true that some dark beers contain barley and brewer's yeast, the alcohol content actually does more harm than good when it comes to supply.
Why Alcohol is Counterproductive
Alcohol can actually inhibit the let-down reflex. It interferes with the release of oxytocin, the hormone responsible for squeezing the milk out of the ducts and down to the nipple. If your milk can't "let down" effectively, your baby may get frustrated, and your breasts may not be fully emptied. Over time, this can actually lead to a decrease in supply.
Furthermore, alcohol can change the flavor of your milk, which might cause some babies to nurse less vigorously. Because we believe that "every drop counts," we want to ensure those drops are easily accessible to your baby.
Choosing Non-Alcoholic Alternatives
If you enjoy the taste of malt or want the benefits of barley without the risks of alcohol, there are plenty of options. Non-alcoholic malt beverages or simple barley water are much better choices. You get the prolactin-boosting beta-glucans without the oxytocin-inhibiting alcohol.
How to Use Barley to Support Your Supply
Incorporating barley into your diet doesn't have to be complicated. It’s a versatile grain with a chewy texture and a slightly nutty flavor. Here are some of our favorite ways to use it:
1. Traditional Barley Water
This is perhaps the most famous way to use barley for lactation.
- How to make it: Rinse half a cup of pearl barley and simmer it in 4 cups of water for about 20-30 minutes. Strain the liquid and flavor it with a bit of lemon and honey.
- Why it works: It’s hydrating and contains the extracted beta-glucans from the grain.
2. Hearty Soups and Stews
Barley is a fantastic thickener for soups. Unlike rice, which can get mushy, barley maintains its texture. A classic vegetable and barley soup is a nourishing meal that provides fiber, minerals, and lactation support all in one bowl.
3. Barley Flakes in Porridge
If you’re tired of standard oatmeal, try swapping in barley flakes. You can cook them just like rolled oats. Top them with flaxseeds and walnuts for an extra boost of healthy fats.
4. Barley Malt Syrup
Barley malt is made from sprouted barley. It is a thick, dark syrup that can be used as a sweetener. It contains those same beneficial polysaccharides and can be added to lactation treats or even a morning cup of decaf coffee.
Milky Mama’s Approach to Lactation Support
While adding barley to your meals is a great step, we know that busy moms often need something more convenient. That’s why we’ve dedicated ourselves to creating products that take the guesswork out of lactation support.
Our lactation treats are designed by a nurse and IBCLC to include ingredients that have been used for generations to support milk supply. For example, our Emergency Brownies are a community favorite for a reason—they are delicious and packed with goodness.
If you’re looking for something that specifically harnesses the power of traditional grains and herbs, our herbal lactation supplements are a great addition to your routine. Products like Pumping Queen™ and Pump Hero™ are formulated to support the hormones involved in milk production and flow.

Other Superfoods for Breastfeeding
Barley isn't the only "superfood" in the lactation world. A varied diet is key to ensuring you have the energy and nutrients required to produce milk. Here are a few other staples we recommend:
Oats
Like barley, oats are high in beta-glucan. They are also a great source of iron. Low iron levels can sometimes lead to a lower milk supply, so starting your day with our Oatmeal Chocolate Chip Cookies or Oatmeal Cookies is a double win.
Leafy Greens
Spinach, kale, and Swiss chard are loaded with calcium, iron, and vitamin K. They also contain phytoestrogens, which may have a positive effect on milk production.
Healthy Fats
Your body needs fat to make the "creamy" hindmilk that helps babies stay full and gain weight. Incorporate avocados, nuts, and seeds (like chia and hemp) into your meals. Our Peanut Butter Chocolate Chip Cookies are a tasty way to get some extra healthy fats in.
Hydration is Essential
You cannot make milk if you are dehydrated. While plain water is great, many moms find they need a little extra help staying hydrated, especially if they are chasing after toddlers. Our lactation drinks, such as Pumpin Punch™ and Milky Melon™, provide hydration with the added benefit of lactation-supporting ingredients.
Practical Scenarios: When to Use Barley
Let's look at how adding barley might look in a real-world setting.
Scenario A: The "Return to Work" Dip Imagine you’ve just returned to work after maternity leave. The stress of the office, the change in your pumping schedule, and the separation from your baby have caused your pump output to drop. You're worried you won't have enough for the daycare bottles tomorrow. In this case, adding a "Barley Power Bowl" for lunch—made with pearl barley, roasted vegetables, and chicken—can provide the complex carbs you need for energy and the beta-glucans to support your prolactin levels. Pairing this with a Virtual Lactation Consultation can help you troubleshoot your pumping flange fit and schedule to get things back on track.
Scenario B: The 4-Month Sleep Regression Your baby is suddenly waking up every two hours, and you feel "empty" by the evening. You're exhausted and your body is struggling to keep up with the increased demand. This is the perfect time for a comforting beef and barley stew. The iron in the beef and the galactagogue properties of the barley help support your body during this high-demand phase. You might also sip on some Lactation LeMOOnade™ throughout the day to keep your fluid levels up.
A Note on Celiac Disease and Gluten
While barley is a wonderful tool for many, it is not suitable for everyone. Barley contains gluten. If you have celiac disease or a non-celiac gluten sensitivity, consuming barley can cause significant health issues and inflammation, which can actually decrease your milk supply by stressing your body.
If you need to avoid gluten but still want to support your supply, focus on gluten-free oats (certified), quinoa, and our gluten-conscious supplement options like Lady Leche™ or Milk Goddess™. Always listen to your body and consult with your doctor if you’re unsure about adding new grains to your diet.

Our virtual lactation consultations allow you to meet with a specialist from the comfort of your own home. We can help you create a personalized plan that includes dietary changes, supplement recommendations, and nursing techniques.
Why Representation Matters in Breastfeeding
At Milky Mama, we are proud to be a Black-owned business that prioritizes representation. For too long, the images and stories of breastfeeding have not reflected the diversity of our communities. We know that Black breastfeeding moms face unique challenges and systemic barriers.
We are here to say: we see you, we support you, and your journey matters. By providing accessible education and culturally competent support, we aim to bridge the gap and empower all families to reach their breastfeeding goals. Whether you’re using barley, oats, or just your own incredible determination, you’re doing an amazing job.
Managing Stress for Better Milk Flow
While we've spent a lot of time talking about what to eat, how you feel is just as important. High levels of cortisol (the stress hormone) can interfere with the let-down reflex.
If you're constantly worried about "does barley increase milk supply" or "am I making enough," that very anxiety could be making it harder for your milk to flow.
- Try "Hand Expression": Sometimes, a few minutes of gentle massage and hand expression before or during pumping can help move the milk.
- Skin-to-Skin: Snuggling your baby chest-to-chest releases a flood of oxytocin.
- Treat Yourself: Taking five minutes to sit down with a cup of tea and some Salted Caramel Cookies isn't just about the galactagogues—it's about giving yourself a moment of peace.
FAQs About Barley and Milk Supply
1. How quickly will I see an increase in milk supply after eating barley?
Every body is different. Some moms notice a difference within 24 to 48 hours, while for others, it may take a week of consistent consumption. Remember that galactagogues are meant to support, not replace, frequent milk removal.
2. Can I use barley if my baby has gas or colic?
Generally, barley is well-tolerated by infants when consumed by the nursing parent. However, every baby is unique. If you notice your baby becomes particularly fussy or gassy after you consume large amounts of barley, try reducing your intake to see if the symptoms improve.
3. Is pearl barley or hulled barley better for lactation?
Hulled barley is the "whole grain" version with only the outermost hull removed, meaning it has more fiber. Pearl barley has been processed more but is still an excellent source of beta-glucan and is much easier to cook. Both are effective for supporting milk supply.
4. Can I drink barley water every day?
Yes, barley water is safe for daily consumption for most people (unless you have a gluten allergy). It is a great way to stay hydrated. Just be mindful of added sugars if you are using store-bought versions or adding lots of honey.
