Introduction
If you’ve spent any time in late-night breastfeeding forums or scroll through parenting groups while nursing, you’ve likely seen the chatter: "I drank a root beer, and suddenly I’m leaking through my breast pads!" or "My grandmother told me root beer is the secret to a heavy let-down." It sounds like one of those charming old wives' tales, right alongside eating spicy food to induce labor or carrying a baby high for a girl. But as a breastfeeding parent, when you’re worried about your supply, you start to look at every soda can and snack in your pantry with a new sense of curiosity.
The question "does root beer increase milk supply?" is more common than you might think. Whether you are a first-time mom navigating the "liquid gold" transition or an experienced parent looking to boost your pumping output for a return to work, understanding what actually moves the needle for milk production is vital. In this guide, we are going to dive deep into the history of root beer, the specific ingredients that people claim are "magical," the role of hydration and sugar, and most importantly, the evidence-based ways to support your breastfeeding journey.
We know that breastfeeding is natural, but it doesn’t always come naturally. It is a skill that you and your baby are learning together. Our goal at Milky Mama is to empower you with the facts so you can make the best choices for your body and your baby. From the science of galactagogues to the importance of support, let's explore whether root beer is truly a lactation aid or just a sweet, bubbly treat.
The History of Root Beer and Lactation
To understand why anyone would associate a fizzy soda with milk production, we have to look back at the origins of root beer. Long before it was a sugary staple in aluminum cans, root beer was an herbal tonic. It was originally a "small beer"—a beverage with very low alcohol content—brewed from an assortment of roots, barks, and herbs.
Historically, these brews often contained ingredients like sassafras, sarsaparilla, birch bark, dandelion root, licorice root, and wild cherry bark. In traditional medicine, many of these ingredients were used for their "tonic" properties, believed to cleanse the blood or improve digestion. Because some of these roots were thought to have mild hormonal effects or to act as "galactagogues" (substances that promote lactation), the connection between the beverage and milk supply was born.
However, there is a significant catch. Modern, commercially produced root beer is very different from the herbal concoctions of the 1800s. Today, root beer is primarily flavored with artificial extracts. In fact, the FDA banned the use of real sassafras oil in commercial food and drugs in 1960 because it contains safrole, which was found to be a potential carcinogen. So, if you are grabbing a bottle of root beer from the grocery store today, you aren’t getting the raw, potent herbs that were used in the "medicinal" versions of the past.
Analyzing the Ingredients: Fact vs. Fiction
When parents ask if root beer increases milk supply, they are often looking for a specific ingredient that might be doing the heavy lifting. Let’s break down the components of modern root beer and see how they stack up against lactation needs.
Sassafras and Sarsaparilla
As mentioned, authentic sassafras is no longer in your soda. However, sarsaparilla (often used in "old-fashioned" styles) is still used in some specialty root beers. Sarsaparilla contains plant sterols that some believe can help balance hormones, but there is no clinical evidence that drinking sarsaparilla-flavored soda will significantly impact your prolactin levels (the hormone responsible for milk production).
Carbonation and Hydration
One of the most overlooked aspects of the "root beer myth" is the hydration factor. Breast milk is about 88% water. If a parent is chronically dehydrated and then drinks a large root beer, the sudden influx of fluid can help the body function more efficiently, potentially leading to a better let-down or a slightly higher volume. However, this isn't unique to root beer; water, Lactation LeMOOnade™, or herbal teas would do the same thing—likely more effectively.
The Sugar Spike
Most commercial root beers are loaded with high fructose corn syrup or cane sugar. There is a theory that the high caloric hit and the quick energy from the sugar might give a tired, calorie-depleted parent a temporary boost. While your body needs calories to produce milk, getting them from refined sugar can lead to an energy crash later on. For more sustained energy and milk-boosting nutrients, we often recommend snacks like Oatmeal Chocolate Chip Cookies which provide complex carbohydrates.
The "Beer" Connection
Sometimes, root beer gets confused with "brewer’s yeast," which is a well-known galactagogue. While non-alcoholic "dark beers" (stouts or porters) are often cited in European traditions as milk boosters due to the barley and yeast content, root beer does not contain these ingredients. It is a soda, not a fermented grain beverage.
The Role of Comfort and Relaxation
Never underestimate the power of the "placebo effect" or the impact of relaxation on breastfeeding. We often tell the families we support that "you’re doing an amazing job," but we also know that stress is one of the biggest enemies of milk flow.
When you are stressed, your body produces adrenaline and cortisol, which can inhibit the release of oxytocin. Oxytocin is the "love hormone" responsible for the let-down reflex—the process that pushes milk out of the breast tissue and into the ducts for your baby or pump.
If drinking a cold root beer is your favorite way to relax after a long day of parenting, that moment of "ahhh" might be exactly what your body needs to trigger a let-down. It isn’t necessarily the root beer itself that is increasing your supply; it’s the fact that you finally sat down, took a breath, and enjoyed something for yourself.
Is Root Beer Safe for Breastfeeding?
In general, drinking root beer in moderation is considered safe while breastfeeding. Unlike many other sodas (like colas or mountain-themed drinks), most brands of root beer are naturally caffeine-free. This is great news for parents who are trying to avoid over-stimulating their babies.
However, there are a few things to keep in mind:
- Sugar Content: High sugar intake can lead to inflammation and energy crashes.
- Artificial Ingredients: Some root beers use artificial colors and preservatives.
- Empty Calories: While you need an extra 300-500 calories a day for breastfeeding, you want those calories to work for you.
If you love the flavor but want something that specifically targets lactation, you might consider herbal supplements that use clean ingredients. For example, our Lady Leche™ supplement is formulated to support supply without the sugar-filled soda.

Better Alternatives for Boosting Milk Supply
If your goal is to see a noticeable and sustainable increase in your milk supply, there are much more effective ways to do it than drinking soda. We believe every drop counts, and your well-being matters too, which is why we focus on nutrient-dense options.
1. High-Quality Lactation Snacks
Instead of empty calories, look for snacks that contain oats, flaxseed, and brewer’s yeast. Our Emergency Brownies are a bestseller for a reason—they are delicious and packed with ingredients that have been used for generations to support nursing parents. If you prefer a cookie, our Salted Caramel Cookies offer a perfect balance of flavor and function.
2. Targeted Hydration
If you find yourself reaching for root beer because you're thirsty, try switching to a beverage designed for lactation. Our Pumpin Punch™ or Milky Melon™ are excellent alternatives that provide hydration along with lactation-supporting herbs. They are refreshing, easy to make, and specifically formulated for the needs of breastfeeding families.
3. Herbal Supplements
Sometimes, diet alone isn't enough, especially during a growth spurt or when returning to work. This is where herbal support comes in. Depending on your specific needs, you might try:
- Pumping Queen™: Designed to support milk supply and flow.
- Dairy Duchess™: Formulated to support milk enrichment and supply.
- Pump Hero™: Great for those looking to maximize their pumping sessions.

The Mechanics of Milk Supply: Demand and Supply
While we love talking about delicious treats and supplements, we must always return to the golden rule of breastfeeding: Milk production is a demand and supply system.
Your breasts were literally created to feed human babies, and they work based on "feedback loops." When milk is removed from the breast (by a baby or a pump), your body receives a signal to make more. If milk stays in the breast, your body receives a signal to slow down production.
If you want to increase your supply, the most effective "secret" isn't a specific food or drink; it’s the frequent and effective removal of milk.
How to Increase Demand:
- Nurse frequently: Aim for 8-12 times in a 24-hour period.
- Power Pumping: This mimics a baby's cluster feeding by signaling the body to produce more milk through rapid-fire demand.
- Check the Latch: If the baby isn't latched correctly, they won't remove milk efficiently, which can tell your body to slow down.
- Skin-to-Skin: Spending time chest-to-chest with your baby increases oxytocin and prolactin.
If you’re struggling with these mechanics, don’t suffer in silence. We offer virtual lactation consultations where you can speak with a professional to get personalized advice tailored to your journey.
Practical Scenarios: When "Old Wives' Tales" Meet Reality
Let’s look at a relatable scenario. Imagine "Sarah," a mom who is three months postpartum and just went back to her office job. She notices that her afternoon pumping session is only yielding half of what it used to. She feels stressed, she’s drinking way too much coffee, and she’s forgetting to drink water.
A coworker tells her, "Try drinking a root beer at lunch! It worked for me." Sarah tries it. That afternoon, she feels a bit more relaxed, she’s better hydrated because of the soda, and she gets an extra ounce. She credits the root beer.
In reality, the root beer provided a moment of relaxation and much-needed fluid. But for Sarah to maintain that increase, she needs a better strategy. She could benefit from swapping that daily soda for a Drink Sampler Pack to see which flavor she enjoys most while getting actual lactation support. She might also benefit from our Breastfeeding 101 class to learn more about maintaining supply while working.
Cultural Perspectives on Lactation Foods
At Milky Mama, we believe representation matters. Different cultures have used various "soul foods" and traditional recipes for centuries to support breastfeeding. In some Caribbean cultures, malt beverages are common. In some Asian cultures, papaya soups are the go-to. The root beer myth likely stems from a Western adaptation of using herbal root tonics.
While it’s wonderful to embrace these traditions, it’s also important to ensure that the modern versions of these foods are actually doing what they claim to do. We are proud to provide a space where Black breastfeeding moms and families from all backgrounds can find evidence-based support that respects these traditions while offering modern, effective solutions.
The Importance of Holistic Support
Boosting milk supply isn't just about what you eat or drink—it's about how you are supported. Breastfeeding in public—covered or uncovered—is legal in all 50 states, yet many parents feel a sense of shame or anxiety that can negatively impact their supply.
Having a community that says, "You’ve got this," is just as important as having a bottle of Milk Goddess™ in your cabinet. That’s why we created The Official Milky Mama Lactation Support Group on Facebook. It’s a place to ask questions like "does root beer increase milk supply?" and get real answers from people who have been there.
When to Seek Professional Help
If you have tried increasing your demand, stayed hydrated, added lactation treats like Peanut Butter Chocolate Chip Cookies, and you still feel like your supply is low, it’s time to reach out to a professional.
Low milk supply can sometimes be caused by underlying medical issues, such as:
- Thyroid imbalances
- Retained placenta
- Hormonal issues (like PCOS)
- Anemia
A Certified Lactation Consultant (IBCLC) can help you troubleshoot your specific situation. Our virtual lactation consultations allow you to get expert help from the comfort of your own home, which is a game-changer for busy parents.
Summary of Root Beer and Lactation
So, to answer the question: Does root beer increase milk supply?
Directly? No. Modern root beer lacks the medicinal herbs in sufficient quantities to act as a galactagogue. However, it may indirectly help some parents by providing hydration, a caloric boost, and a reason to relax, which can help with the let-down reflex.
If you love root beer, go ahead and enjoy one! But if you are looking for a reliable, science-backed way to support your lactation journey, focus on:
- Frequent milk removal (the most important factor).
- Balanced nutrition including lactation snacks.
- Hydration with lactation drink mixes.
- Targeted herbal support like Milky Maiden™.
- Community and professional support.
FAQ
1. Does root beer have caffeine?
Most major brands of root beer are caffeine-free, making them a safer choice for breastfeeding parents than many other sodas. However, you should always check the label, as some specialty or "energy" root beer brands may add caffeine.
2. Can the sugar in root beer cause issues for my baby?
While a moderate amount of sugar in your diet doesn't typically change the sugar content of your breast milk, high sugar intake can affect your energy levels and overall health. Some babies may be sensitive to artificial flavors or preservatives used in some sodas, which could result in fussiness or gas.
3. Is there a "lactation beer" that is better than root beer?
The term "lactation beer" usually refers to a non-alcoholic herbal brew made with ingredients like ginger, barley, and brewer’s yeast. These are much more effective than commercial root beer because they contain actual galactagogues that support prolactin levels.
4. What should I drink instead of root beer to increase my supply?
For better results, we recommend high-quality, targeted drinks like Pumpin Punch™ or Lactation LeMOOnade™. These provide the hydration you need along with ingredients that are specifically chosen to support breastfeeding families.
