Introduction
Have you ever sat there during a late-night pumping session, staring at the bottle and wishing there was a magic button you could press to make your body produce more milk? If you’ve been searching for ways to boost your output, you’ve likely come across the word "prolactin." It’s often called the "milk-making hormone," and for a good reason. But as you navigate the sea of advice on forums and social media, you might find yourself wondering: can you take prolactin to increase milk supply directly?
It is a question we hear often at Milky Mama. Whether you are a first-time parent navigating the "liquid gold" days or a seasoned pro trying to maintain a stash while returning to work, the desire to provide for your little one is powerful. We want you to know right now: you’re doing an amazing job. Breastfeeding is a beautiful, natural process, but it doesn’t always come naturally, and it is perfectly okay to look for support along the way.
In this guide, we are going to dive deep into the science of prolactin. We’ll explore what it actually is, how it functions within your body, and the current medical reality of taking prolactin as a supplement or medication. We will also look at the different ways you can naturally encourage your body to release more of this vital hormone and how our community and products can support you in reaching your breastfeeding goals. Our mission is to empower you with evidence-based information so you can make the best decisions for your unique journey.
How Prolactin Works in Your Body
To understand if you can "take" prolactin, we first need to understand what it does. Prolactin is a hormone produced by the pituitary gland, a tiny pea-sized organ at the base of your brain. While it has hundreds of functions in the human body, its most famous role is stimulating the mammary glands to produce milk.
The Pregnancy Prep
During pregnancy, your prolactin levels naturally skyrocket, often reaching ten to twenty times their usual levels. This is your body’s way of preparing the "equipment." However, you don’t usually see a full milk supply during pregnancy because other hormones—estrogen and progesterone produced by the placenta—actually block prolactin from doing its main job. They keep the milk production "on hold" until the baby arrives.
The Postpartum Shift
Once you give birth and the placenta is delivered, those levels of estrogen and progesterone plumet. This is the signal prolactin has been waiting for! With the "brakes" removed, prolactin steps in to kickstart milk production. In those first few days, this hormonal surge is what leads to your milk "coming in."
The Supply and Demand Cycle
After the initial hormonal surge of the first few days, milk production transitions from being purely hormone-driven to being "autocrine" or supply-and-demand driven. This is where the magic of nursing and pumping comes in. When your baby latches or you use a breast pump, the nerves in your nipple send a direct message to your brain. Your brain responds by releasing two key hormones:
- Oxytocin: This causes the "let-down reflex," squeezing the milk out of the ducts.
- Prolactin: This tells your body to get to work making the next meal.
We often say that breasts were literally created to feed human babies, and this feedback loop is a testament to how incredible our bodies are. The more milk you remove, the more prolactin your brain releases, and the more milk you make.
Can You Take Prolactin to Increase Milk Supply?
Now, let’s answer the big question: can you actually take prolactin?
Currently, in the United States and most other countries, you cannot simply go to a pharmacy or a health food store and buy a prolactin pill. Prolactin is a complex protein hormone, and if you were to swallow it as a standard supplement, your digestive system would likely break it down before it ever reached your bloodstream to do its job.
Research into Recombinant Human Prolactin (r-hPRL)
There is ongoing medical research regarding "recombinant human prolactin." This is a lab-created version of the hormone. Studies have shown that when administered via injection, r-hPRL can significantly increase milk volume. This research is particularly focused on two groups:
- Moms with true prolactin deficiency: Some women have medical conditions, such as Sheehan’s Syndrome (pituitary damage) or rare genetic conditions, where their bodies simply do not produce enough prolactin. For these mothers, taking exogenous prolactin could be life-changing.
- Moms of premature infants: Mothers of preemies often struggle with supply because they are relying entirely on pumps rather than the natural stimulation of a baby’s latch. Research has shown that twice-daily injections of r-hPRL can help these mothers increase their output.
While this is exciting for the future, it is not yet a standard treatment available to the general public. It remains largely in the realm of clinical trials and specialized medical cases.
The Future: Prolactin-XL
Scientists are also working on long-lasting versions of the hormone, sometimes called Prolactin-XL. The goal is to create a treatment that stays in the body longer so it wouldn't require frequent injections. This could eventually become a tool for "emergency" supply boosts or to help families in crisis situations where access to nutrition is limited. But for now, for the average breastfeeding parent, "taking" prolactin isn't an option.
Medical Alternatives: Dopamine Antagonists
If you can't take prolactin directly, how do doctors help mothers with low supply? They often look at the "inhibitors." In your brain, a chemical called dopamine acts as a brake for prolactin. It keeps your prolactin levels in check when you aren't breastfeeding.
Medicines that increase milk supply, known as galactagogues, usually work by blocking dopamine. When you block the dopamine, the "brakes" come off, and your pituitary gland releases more prolactin.
Domperidone (Motilium)
Domperidone is one of the most well-known medications used for this purpose globally. While it was originally designed to treat stomach issues and nausea, its side effect of increasing prolactin made it a popular choice for lactation support.
- Availability: It is used widely in Canada, Australia, and the UK. However, it is not FDA-approved in the United States for lactation due to concerns about potential cardiac side effects at high doses.
- Safety: Many breastfeeding experts consider it relatively safe when used under strict medical supervision, but you must consult your healthcare provider before considering this route.
Metoclopramide (Reglan)
Reglan is more commonly used in the U.S. because it is FDA-approved (though for digestive issues, not specifically for lactation). Like Domperidone, it increases prolactin by blocking dopamine.
- The Downside: Reglan can cross the blood-brain barrier, which means it has a higher risk of side effects like extreme fatigue, irritability, and, most significantly, depression. For a new mom already navigating the "baby blues" or postpartum depression, this can be a risky choice.
Natural Ways to Boost Your Prolactin Levels
Since you can't easily take prolactin in a pill, the best strategy is to encourage your body to make its own. The good news is that your body is designed to do exactly this! Here are the most effective ways to naturally spike your prolactin levels.
1. Increase Frequency of Milk Removal
This is the number one rule of lactation: supply and demand. Every time you nurse or pump, you are triggering a prolactin surge. If you are struggling with supply, try adding an extra pumping session or a "power pumping" hour to your day. Power pumping mimics a baby’s cluster feeding, which is nature’s way of telling the brain, "Hey, we need more prolactin over here!"
2. Prioritize Skin-to-Skin Contact
Never underestimate the power of a "baby moon." Spending time skin-to-skin with your baby (often called Kangaroo Care) triggers a massive release of both oxytocin and prolactin. It calms the baby, lowers your stress levels, and tells your endocrine system that it is time to produce. Even if you are an exclusive pumper, holding your baby close before or during a session can help.
3. Nighttime Pumping or Nursing
Did you know that prolactin levels are naturally higher during the night? While we all crave a full night's sleep, those 2:00 AM and 5:00 AM sessions are actually the most productive for many moms. If you're trying to build a stash or increase your daily total, don't skip the night sessions.
4. Proper Latch and Equipment
If the baby isn't latching efficiently, or if your pump flanges are the wrong size, your breasts aren't being stimulated correctly. This means the message isn't getting to your brain to release prolactin. If you’re feeling pain or seeing low output despite frequent sessions, it’s time to reach out for professional help. We offer virtual lactation consultations to help you troubleshoot these exact issues from the comfort of your home.
5. Hydration and Nutrition
While water alone won't make milk, dehydration can definitely hinder your body's ability to function. Your body needs resources to create milk. Staying hydrated with something like our Lactation LeMOOnade™ or Pumpin Punch™ can make the process easier and provide the support you need.
The Milky Mama Approach: Herbal Support for Prolactin
While you can't take the hormone itself, many cultures have used specific herbs for centuries to support milk production. Modern science suggests that some of these herbs may work by supporting the pituitary gland or mimicking the effects of the hormones involved in lactation.
At Milky Mama, we believe in the power of nature combined with scientific understanding. We’ve formulated several herbal supplements designed to support your body’s natural processes without the use of harsh chemicals.
Our Herbal Supplements
- Lady Leche™: This is one of our most popular liquid supplements. It uses organic herbs known for their ability to support the endocrine system and encourage a healthy milk flow.
- Pumping Queen™: Specifically designed for our pumping mamas, this blend focuses on optimizing output and supporting the hormonal triggers needed for a successful session.
- Pump Hero™: This is a great choice for those looking to support mammary tissue health and overall supply.
- Dairy Duchess™: A powerful blend that helps many moms see that extra boost they’ve been looking for.
Note: These products are not intended to diagnose, treat, cure, or prevent any disease. Consult with your healthcare provider for medical advice.
We always recommend starting with one supplement to see how your body reacts. Every woman’s hormonal makeup is different—what works wonders for your best friend might not be the perfect fit for you. That’s why we offer a variety of options like Milk Goddess™ and Milky Maiden™.
Factors That Might Be Lowering Your Prolactin
Sometimes, increasing supply isn't just about adding things—it's about identifying what might be getting in the way. Several lifestyle factors and medications can inadvertently lower your prolactin levels:
- Smoking: Nicotine has been shown to decrease prolactin levels and can lead to earlier weaning.
- Estrogen-based Birth Control: The "combination pill" contains estrogen, which, as we discussed earlier, can block the effects of prolactin. If you need hormonal birth control, most IBCLCs recommend the "mini-pill" (progesterone only).
- Significant Stress: High levels of cortisol (the stress hormone) can inhibit the release of oxytocin, making it harder for milk to flow, which eventually tells the brain to stop making as much prolactin.
- Certain Medications: Decongestants containing pseudoephedrine are famous for "drying up" milk supply because they restrict blood flow and affect hormonal signals.
- Retained Placenta: If even a tiny piece of the placenta remains in the uterus after birth, it can continue to release progesterone, which prevents prolactin from fully taking over.
If you suspect any of these factors are at play, we encourage you to join The Official Milky Mama Lactation Support Group on Facebook. It is a safe, judgment-free space where you can share your experience and get advice from others who have been in your shoes.
Practical Scenarios: When You Need a Supply Boost
We know that breastfeeding isn't lived in a lab; it's lived in the middle of the night, in office breakrooms, and during family vacations. Here are a few real-world scenarios where focusing on prolactin and supply becomes vital.
Returning to Work
The "Work-Pump-Slump" is a real thing. When you move from nursing your baby directly to using a machine, your brain might not receive the same strong prolactin signals. To combat this, many moms find success by looking at photos of their baby while pumping or by snacking on Oatmeal Chocolate Chip Cookies during their break. The combination of targeted nutrition and emotional connection can help maintain those levels.
The "Late-Onset" Supply Drop
Some moms have a great supply for three or four months, then suddenly see a dip. This often happens when your period returns or when the baby starts sleeping longer stretches. To bring those levels back up, you might try a few days of power pumping and adding a supplement like Lady Leche™.
Induced Lactation (Adoption or Surrogacy)
It is a fun fact: breastfeeding in public—covered or uncovered—is legal in all 50 states, but did you know you can also breastfeed a baby you didn't give birth to? This is called induced lactation. It involves a dedicated schedule of pumping (sometimes every 2-3 hours) to trick the brain into thinking a baby has arrived. This creates a rise in prolactin that eventually leads to milk production. It takes incredible dedication, but it is a beautiful way to bond. If this is your path, our Online breastfeeding classes can provide the roadmap you need.
The Role of Support and Mental Well-being
We cannot talk about hormones without talking about your heart. Breastfeeding is as much a mental game as it is a physical one. When you are worried about every ounce, your body is in a state of "fight or flight," which is the enemy of the "rest and digest" state needed for lactation.
At Milky Mama, we always say that every drop counts—and your well-being matters too. If you are struggling, please don't suffer in silence. Whether it's through our Instagram community or a one-on-one session with a professional, reaching out is a sign of strength, not weakness.
Sometimes, the best thing you can do for your prolactin levels is to hand the baby to a partner, eat a delicious Emergency Brownie, and take a nap. A rested mama is a mama whose body can better handle the complex task of making milk.
Understanding the "Every Drop Counts" Philosophy
In a world that often pressures moms to produce massive amounts of milk (the "oversupply" culture you see on TikTok), it’s easy to feel like you’re failing if you aren't filling gallon jugs. We want to normalize the "just-enougher" journey.
If you are producing what your baby needs, you are successful. If you are supplementing and still giving your baby a few ounces of breast milk a day, you are successful. Those few ounces are packed with the antibodies and hormones your baby needs. Your worth as a mother is not measured in milliliters.
Our products, like the Fruit Sampler or our Salted Caramel Cookies, are designed to give you a delicious, supportive tool in your toolkit, but they are just one part of the puzzle. The most important part is you.
Conclusion

By understanding the science of how your body works, you can use frequency, skin-to-skin contact, and targeted herbal support to maximize your natural prolactin production.
Whether you choose to use our Emergency Brownies for a quick boost or consult with us for a more detailed plan, know that we are here for you. Breastfeeding is a marathon, not a sprint, and every family deserves a cheering squad.
You are doing an incredible job providing for your baby. Remember to be kind to yourself, stay hydrated, and reach out for help whenever you need it. We’re in this together.
FAQ
1. Can I get a prolactin prescription from my doctor? In most cases, doctors do not prescribe prolactin itself. Instead, they may prescribe medications like Reglan or Domperidone (depending on your country) that help your body release more of its own prolactin. Always talk to your healthcare provider about the risks and benefits of these medications.
2. How long does it take for prolactin levels to increase after I start pumping more? While your brain releases prolactin almost immediately when you start a pump session, it often takes 3 to 7 days of consistent increased frequency to see a noticeable change in your actual milk volume. Consistency is the key!
3. Are there any foods that increase prolactin? While there is no "magic food" that contains prolactin, certain foods called lactogenic foods—like oats, flaxseed, and brewer's yeast—are believed to support the hormones involved in lactation. This is why our Oatmeal Cookies are such a staple for many breastfeeding parents.
4. Does stress actually stop prolactin production? Stress doesn't usually stop the production of prolactin, but it can stop the release of oxytocin. If the milk isn't being released (let down), the milk stays in the breast. When the breast stays full, it sends a signal to the brain to stop making prolactin. So, indirectly, chronic stress can lead to a decrease in your supply over time.
