Did you know that within moments of your baby latching onto your breast, a complex chemical signal travels from your nipple to your brain, triggering a surge of hormones that literally tells your body to create life-sustaining nourishment? It is an incredible, high-tech biological process. However, for many of us, that "factory" doesn't always feel like it's running at full capacity. If you’ve ever looked at your breast pump flange and felt a pang of worry because the ounces aren't adding up to what you expected, you are not alone. It is one of the most common concerns we hear from breastfeeding parents: "How do I make more milk, and can I just take the hormone responsible for it?"
In this article, we are going to dive deep into the science of lactation to answer the question: Can I take prolactin to increase milk supply? We will explore what prolactin actually does in your body, the reality of "taking" hormones versus supporting their production, and the safe, evidence-based ways you can boost your supply. We’ll also look at the role of pharmaceutical galactagogues, herbal supports, and the fundamental lifestyle shifts that can help you reach your breastfeeding goals.
At Milky Mama, we believe that breastfeeding is natural, but it doesn’t always come naturally. Whether you are exclusively chest-feeding, pumping for a NICU warrior, or trying to increase your stash for a return to work, we are here to provide the compassionate, expert-backed information you deserve. Our main message today is simple: while you can’t exactly grab a bottle of pure prolactin off a shelf, there are powerful ways to work with your body's endocrine system to support every drop.
To understand if you can "take" prolactin, we first need to understand what it is. Prolactin is a hormone produced by the anterior pituitary gland in your brain. While it has hundreds of functions in the human body, its most famous role is as the primary driver of milk production.
Throughout your pregnancy, your prolactin levels actually rise significantly. By the time you reach your third trimester, your levels might be ten to twenty times higher than they were before you conceived. However, you aren't usually producing a full milk supply yet. Why? Because the high levels of estrogen and progesterone produced by the placenta act as a "brake" on the milk-making process. They allow the breast tissue to develop but prevent the actual "milk factory" from starting its engines.
The moment the placenta is delivered after birth, those estrogen and progesterone levels plummet. This is the signal your body has been waiting for. The "brake" is released, and prolactin takes center stage, telling the alveoli (the milk-producing cells in your breasts) to start synthesizing milk.
In the early weeks of breastfeeding, prolactin works on a very specific cycle. Every time your baby latches or you use a breast pump, the nerves in your nipple send a message to your brain to release more prolactin. This surge helps create the milk for your next feeding.
This is why we often say "breastfeeding is a game of supply and demand." If the milk is removed frequently, prolactin levels stay high, and the body continues to produce. If milk removal is infrequent, prolactin levels begin to dip, signaling to the body that it can slow down production. This is also why Online breastfeeding classes often emphasize the importance of early and frequent stimulation to "lock in" those prolactin receptors in the first few weeks.
When parents ask, "Can I take prolactin to increase milk supply?" they are usually looking for a direct supplement—a pill or a liquid that contains the hormone itself.
Currently, there is no "over-the-counter" prolactin hormone. There have been clinical studies involving something called Recombinant Human Prolactin (r-hPRL). These studies have shown that in very specific cases—such as mothers with a true prolactin deficiency or mothers of premature infants who have seen a significant drop in supply while pumping—direct injections of this engineered hormone can increase milk volume.
However, r-hPRL is not currently FDA-approved for general use in increasing milk supply. It is largely restricted to clinical research settings. Furthermore, because prolactin is a protein, it cannot be taken as a simple pill; it would be broken down by your digestive system before it ever reached your bloodstream. This means that if it were available, it would likely require injections, similar to how insulin is administered.
For the vast majority of breastfeeding parents, the issue isn't a lack of prolactin in the body, but rather a need for better "communication" between the breasts and the brain. Unless you have a medical condition like Sheehan’s Syndrome (pituitary damage) or another endocrine disorder, your body likely has the capacity to produce the prolactin you need. Instead of looking for the hormone itself, we usually focus on galactagogues—substances that help your body produce more of its own prolactin.
Since we can't easily take prolactin directly, the medical community sometimes uses medications that influence prolactin production indirectly. These are known as dopamine antagonists.
To understand these, you need to know that dopamine is the "stop sign" for prolactin. In your brain, dopamine tells the pituitary gland to stop making prolactin. By taking a medication that blocks dopamine, you essentially remove that stop sign, allowing prolactin levels to rise.
Metoclopramide is a medication often used for digestive issues, but it is sometimes prescribed "off-label" to increase milk supply. While it can be effective at raising prolactin levels, it comes with significant risks.
One of the most concerning side effects of Metoclopramide is its impact on mental health. It has been known to cause or worsen depression and anxiety in some postpartum parents. Because the postpartum period is already a time of high emotional vulnerability, we always recommend discussing this thoroughly with your healthcare provider. If you have a history of depression, this may not be the right path for you.
Domperidone is perhaps the most well-known pharmaceutical galactagogue globally. It is often preferred over Metoclopramide because it does not cross the blood-brain barrier as easily, meaning the risk of psychiatric side effects like depression is lower.
However, it is important to note that Domperidone is not currently approved by the FDA in the United States for the purpose of increasing milk supply due to concerns regarding potential cardiac side effects (such as heart arrhythmias) when used at high doses or in certain populations. In other countries, such as Canada and parts of Europe, it is frequently prescribed for lactation support.

If you are looking for ways to support your milk-making manager without turning to experimental injections or heavy-duty prescriptions, there are several evidence-based strategies to naturally boost your prolactin.
The most effective way to raise prolactin is through nipple stimulation and breast emptying. Every time you remove milk, your body gets the message to make more. If you feel your supply is dipping, try adding a "power pumping" session or an extra nursing session during the night. Prolactin levels are naturally higher during the overnight hours, so nursing between 1:00 AM and 5:00 AM can be particularly effective for boosting your overall daily supply.
We often talk about the "Golden Hour" after birth, but skin-to-skin contact is a powerful tool throughout your entire journey. Snuggling your baby chest-to-chest (known as Kangaroo Care) triggers a massive release of oxytocin and supports prolactin production. It’s not just "cuddle time"—it’s biological medicine.
It isn't just about how often you remove milk, but how well you remove it. If your baby has a shallow latch or your pump flanges are the wrong size, your breasts may not be sending the right signals to your brain. This is where Virtual lactation consultations can be a game-changer. A professional can look at your setup and ensure you are actually emptying the breast, which is the key to keeping those prolactin levels high.
For many families, herbal supplements offer a bridge between lifestyle changes and pharmaceuticals. Certain herbs have been used for centuries to support the endocrine system and encourage healthy prolactin levels.
When choosing an herbal supplement, it is important to look for blends that target your specific needs. For example, our Milk Goddess™ supplement is specifically formulated with ingredients like Goat's Rue and Moringa, which are known to support mammary tissue development and milk production.
When researching "can I take prolactin to increase milk supply," you will likely come across many herbal recommendations. Here are some of the most effective options that we use in our formulations:
A Note on Safety: You may have heard of an herb called "fenugreek." While it is popular, it can cause significant side effects for some, including digestive upset for both mom and baby, and it can interfere with certain medical conditions like thyroid issues or blood sugar regulation. At Milky Mama, we choose to formulate our products without it to ensure they are as gentle and effective as possible for all our families.

You cannot pour from an empty cup—literally. While prolactin is the manager of the factory, your nutrition and hydration are the raw materials. If the manager is yelling "make milk!" but there's no water or energy in the building, the factory can't produce.
Breast milk is about 87% water. If you are dehydrated, your body will prioritize your own survival over milk production. However, simply chugging plain water isn't always enough. You need electrolytes—like magnesium, potassium, and calcium—to help your cells actually absorb that water.
This is why many moms find success with specialized lactation drink mixes. Our Pumpin Punch™ and Milky Melon™ are designed to provide both hydration and lactation-supporting herbs in a delicious, easy-to-use format.
In many cultures, specific foods are given to new mothers to help "bring in the milk." These are often rich in complex carbohydrates and healthy fats.
If you are looking for a delicious way to incorporate these, our Emergency Brownies and Oatmeal Chocolate Chip Cookies are a fan-favorite way to snack with a purpose.
Sometimes, you might be doing "everything right," but your prolactin levels are still struggling to stay elevated. It is helpful to look at potential "prolactin blockers" in your life.
When you are under extreme stress, your body releases adrenaline and cortisol. These are the "fight or flight" hormones. Evolutionarily, if you were being chased by a predator, your body would temporarily shut down non-essential functions—like milk production—to save energy for running away.
In the modern world, that "predator" might be a demanding job, financial stress, or a lack of support. While we can't always eliminate stress, we can try to mitigate it. Try to find five minutes of deep breathing while you pump, or use The Official Milky Mama Lactation Support Group on Facebook to connect with other parents who understand what you’re going through. Validation and community are powerful stress-reducers.
Be aware that some medications can inadvertently lower your prolactin levels:
Let’s look at a few real-world situations where the question "can I take prolactin" often comes up, and what the better approach might be.
The Challenge: "I’ve been back at work for a month, and I’m noticing I’m getting two ounces less per session than I used to. I’m stressed and want to know if there's a pill to fix this." The Milky Mama Approach: Instead of a prolactin pill, we look at the routine. Are you pumping long enough to get a second letdown? Are your pump parts worn out? Adding a Drink Sampler Pack to your desk can help you stay hydrated while providing herbal support, and a quick Breastfeeding 101 class could help you troubleshoot your pumping technique.
The Challenge: "My baby is in the NICU, and I can't nurse them directly. My supply is plummeting despite pumping every three hours." The Milky Mama Approach: This is a case where "relative prolactin deficiency" often occurs because the pump isn't as efficient as a baby. We recommend maximal skin-to-skin (Kangaroo Care) whenever possible and potentially a high-potency supplement like Pumping Queen™ to help bridge the gap.
The Challenge: "I am adopting a baby and want to produce milk. I heard I need to take prolactin to make it happen." The Milky Mama Approach: Inducing lactation is a beautiful journey that mimics pregnancy. It usually involves a combination of hormonal therapy (prescribed by a doctor) and rigorous pumping to stimulate prolactin. Using a supplement collection and working closely with a consultant can help make this possible.
In our society, we often put so much pressure on ourselves to produce a specific amount of milk. We see "over-suppliers" on social media and feel like we are failing if we don't have a freezer full of bags.
But here is the truth: Every drop counts. Whether your body is producing 40 ounces a day or 4 ounces a day, you are providing your baby with incredible antibodies, stem cells, and nutrition that only you can give. Your well-being matters just as much as your milk supply. If the quest for "more prolactin" is causing you to lose sleep or feel a sense of shame, take a deep breath. You are doing an amazing job.
Breasts were literally created to feed human babies, and your body is doing its best. Sometimes, that means we need a little extra help—whether that's a consultation, a supplement, or just a really good brownie.
While herbal supports and lifestyle changes are wonderful, there are times when you need to call in the experts. You should reach out to an IBCLC (International Board Certified Lactation Consultant) or your healthcare provider if:
We offer Virtual lactation consultations so you can get professional, compassionate advice from the comfort of your own home, no matter where you are.
So, can you take prolactin to increase milk supply? The short answer is that while you can't buy a bottle of prolactin, you can take steps to support your body's production of it. By focusing on frequent milk removal, proper hydration, effective herbal supplements, and your own mental well-being, you can work with your body’s natural design.
Remember:
Whether you're just starting your journey or you're a seasoned pro looking for a boost, we are here for you. You've got this, Mama!
1. How do I know if my prolactin levels are actually low? While you can get a blood test to check prolactin levels, it’s not always the most helpful indicator because levels fluctuate throughout the day. Usually, we look at clinical signs like low milk volume, lack of breast changes during pregnancy, or a history of pituitary issues. If you’re concerned, a healthcare provider can order a test.
2. Is there a "prolactin pill" I can buy over the counter? No. Prolactin is a protein hormone and would be destroyed by your stomach acid if taken as a pill. "Prolactin support" supplements you see online usually contain herbs (like those in our Milk Goddess™) that help your body make more of its own prolactin, rather than the hormone itself.
3. Will taking a prolactin-boosting supplement work if I don't pump or nurse frequently? Supplements are designed to supplement the process, not replace it. Because lactation is a supply-and-demand system, the most important thing you can do is remove milk. A supplement like Dairy Duchess™ works best when paired with regular milk removal.
4. Can I boost prolactin if I've already stopped breastfeeding for a few weeks? Yes, this is called relactation! It takes time, patience, and lots of stimulation (pumping and nursing), but it is possible. Your body can re-establish prolactin production with consistent effort and often the help of galactagogues.
