Imagine you’ve finally settled into a rhythm with your little one. The late-night feedings are becoming a bit more predictable, your nursing bond is growing stronger every day, and you’ve finally found a moment to treat yourself to a refreshing iced peppermint tea or perhaps a festive peppermint mocha. But as you take that first sip, a nagging thought crosses your mind: "Wait, I heard somewhere that peppermint might dry up my milk." Suddenly, that moment of relaxation is replaced by a wave of "lactation anxiety." Is your favorite refreshing flavor actually a hidden enemy to your breastfeeding journey?
At Milky Mama, we understand that every choice you make—from what you eat to how you rest—is filtered through the lens of how it might affect your baby. We know that for many parents, especially Black breastfeeding moms who may already face systemic barriers to support, the pressure to maintain a "perfect" supply can be overwhelming. We believe that breastfeeding is natural, but it doesn’t always come naturally, and navigating the world of herbal safety shouldn't feel like a solo mission. Our goal is to empower you with evidence-based information so you can make choices that feel right for your body and your baby.
In this deep dive, we are going to explore the complex relationship between peppermint and lactation. We will look at what the science says, why some mothers notice a dip in supply while others don't, and how different forms of peppermint—from candies and teas to essential oils—might impact your milk production. We’ll also provide practical steps for what to do if you suspect a dip in supply and how to keep your journey on track.
The main message we want you to take away is this: While peppermint can potentially lower milk supply for some individuals, it is not a "one-size-fits-all" reaction. Your unique biochemistry plays a huge role, and being informed is your best tool for success. You’re doing an amazing job, and we’re here to help you protect every drop.
Peppermint (Mentha x piperita) is a hybrid mint, a cross between watermint and spearmint. It’s been used for centuries across various cultures for its medicinal properties and its crisp, cooling taste. The primary active ingredients in peppermint are menthol and menthone, which give the herb its characteristic aroma and "cooling" sensation.
In the world of herbalism, peppermint is often celebrated for its ability to soothe digestive issues, alleviate headaches, and even help clear up congestion. However, when it comes to breastfeeding, peppermint falls into a category known as "antigalactagogues." These are substances that are traditionally believed to reduce or "dry up" milk supply.
It is important to remember that breasts were literally created to feed human babies, and our bodies are incredibly resilient. However, certain herbs can interact with our hormones or the cellular processes within the breast tissue. Because peppermint is so ubiquitous—found in everything from toothpaste and chewing gum to luxury chocolates and aromatherapy—it is one of the most common herbs breastfeeding parents ask us about.
When we look at the question "does peppermint lower milk supply," we have to look at two different types of evidence: clinical research and anecdotal reports from the breastfeeding community.
Currently, there are very few large-scale human clinical trials specifically measuring milk volume after peppermint consumption. Most of the data we have comes from animal studies or in vitro (cell culture) research. For instance, some studies have shown that high doses of menthol can suppress milk production in lactating mammary epithelial cells. This suggests that, at a cellular level, peppermint has the potential to interfere with the way milk is produced.
In humans, the LactMed database, which is a reliable source for drugs and lactation, notes that peppermint has been used traditionally to suppress lactation. While it is "Generally Recognized as Safe" (GRAS) by the FDA as a food ingredient, its use in therapeutic doses during breastfeeding is a different story.
Interestingly, the impact of peppermint seems to vary significantly from person to person. Expert observations and community polls have suggested that roughly 30% of breastfeeding parents may notice a decrease in supply after consuming peppermint, while about 70% notice no change at all. This tells us that individual sensitivity is a major factor. Some mothers can enjoy a peppermint brownie every day without a single ounce of difference, while others might see a dip after a few strong peppermint candies.
Not all peppermint is created equal. The concentration of menthol—the component most likely responsible for supply issues—varies wildly depending on how the peppermint is prepared.
Peppermint tea is a common household staple. While one cup of tea is generally considered a low dose, drinking several cups of strong, steeped peppermint tea throughout the day could potentially reach a therapeutic level that impacts supply. If you are a tea lover, we often suggest alternating with more lactation-friendly options or staying mindful of any changes in your baby's satisfaction or your pumping output.
This is perhaps the most potent form of the herb. Essential oils are highly concentrated. Using peppermint oil for a massage or applying it topically (even diluted) allows the menthol to enter your bloodstream and, eventually, your breast milk. Some mothers report a significant "tanking" of their supply after using peppermint oil for migraines or muscle pain. If you enjoy aromatherapy, consider diffusing the oil in a well-ventilated room for short periods rather than applying it directly to your skin, or better yet, look for lactation-safe alternatives.
Most gum and standard mints use artificial flavoring or very small amounts of natural peppermint oil. For the majority of parents, these are unlikely to cause a problem. However, "strong" mints or "altoid-style" candies often contain higher concentrations of real peppermint oil. If you find yourself reaching for these throughout the day, it's worth keeping an eye on your supply.
The peppermint extract used in holiday cookies or the occasional sprig of fresh mint in a salad is usually quite minimal. Unless you are consuming peppermint-heavy dishes in large quantities every day, culinary uses are generally considered safe for most breastfeeding parents.
Let’s look at some practical situations where peppermint might pop up in your life and how to navigate them.
It’s December, and peppermint is everywhere. You’ve had a peppermint mocha in the morning and a few peppermint bark treats at an office party. A few days later, you notice that your breasts don't feel as full, or your baby seems extra fussy at the breast. In this case, the cumulative effect of several peppermint treats might be affecting your supply.
Our Advice: If you notice a dip, the first step is to cut back on the peppermint. You can also boost your hydration with something like our Pumpin Punch™, which provides hydration along with lactation-supporting ingredients.
Many cough drops and chest rubs contain menthol (derived from peppermint). If you’re battling a winter cold, you might be using these products frequently. This is a common time for moms to see a supply dip—partly because of the illness and dehydration, and partly because of the menthol.
Our Advice: Look for menthol-free cough drops (like those flavored with lemon or honey) and focus on staying hydrated. If you feel like your supply needs a little extra "oomph" while you recover, our Emergency Brownies are a delicious way to give your body some extra support.
Some traditional remedies suggest peppermint water or gels for cracked nipples. While some studies show it can be effective for healing, there is a risk of the baby ingesting it, and the proximity to the breast tissue could potentially impact local milk production.
Our Advice: We generally recommend using expressed breast milk or specialized, lactation-safe nipple creams instead. If you are struggling with nipple pain, we highly recommend booking one of our virtual lactation consultations to address the root cause, such as a latch issue.
If you’ve realized that peppermint might have affected your supply, please don't panic! For most people, this dip is temporary and can be reversed with a few days of focused effort. Remember: "Every drop counts," and you can get back to where you want to be.
We know that breastfeeding is a marathon, not a sprint. There will be hurdles along the way, and a peppermint-related supply dip is just one of many things you might encounter. That’s why we’ve created a range of products and services designed to meet you wherever you are in your journey.
Sometimes, you just need a snack that works as hard as you do. Our Lactation Snacks collection includes everything from our famous Oatmeal Chocolate Chip Cookies to our Salted Caramel Cookies. These treats are designed to be a convenient and tasty way to incorporate supportive ingredients into your diet.
If you’re looking for specific support, our herbal supplements are formulated by our founder, Krystal Duhaney, who is an RN, BSN, and IBCLC. Whether you choose Dairy Duchess™, Milk Goddess™, or Pump Hero™, you can feel confident knowing you’re using products designed with a deep understanding of lactation biology.
You don’t have to do this alone. We encourage you to join The Official Milky Mama Lactation Support Group on Facebook, where you can connect with thousands of other parents sharing their experiences. For more structured learning, our Online breastfeeding classes, including Breastfeeding 101, offer a wealth of knowledge to help you feel prepared and empowered.

One thing we always want to emphasize at Milky Mama is that you do not need to have a "perfect" diet to breastfeed successfully. We’ve seen many moms become so afraid of "bad" foods that they end up stressed and undernourished. Stress can actually be a bigger supply-killer than a single peppermint candy!
While it's good to be aware that peppermint can lower milk supply, it shouldn't make you afraid to eat. If you accidentally have something with mint, don't beat yourself up. Most of the time, the effect is dose-dependent. Your body is a powerful milk-making machine, and it can handle the occasional slip-up.
Our philosophy is about addition, not just subtraction. Instead of focusing only on what to avoid, focus on what you can add to support your well-being. Add in more rest, add in more skin-to-skin time, add in supportive communities, and add in nourishing foods and drinks that make you feel good.
While your supply is a primary concern, you might also wonder if peppermint affects your baby directly. When you consume peppermint, small amounts of menthol and other compounds can pass into your breast milk.
Some research has noted that babies might react to the change in the flavor of the milk. One study mentioned infants looking "puzzled" or stopping to smell the milk before continuing to nurse. Most babies don't seem to mind, but if your little one is particularly sensitive or prone to reflux, you might notice they become more agitated.
Furthermore, it’s worth noting that while peppermint is often used to treat colic in older children and adults, it is generally not recommended for direct use in infants under six months old, as menthol can sometimes cause breathing difficulties or spasms in very young babies. By consuming it yourself, the amount reaching the baby is very small, but it's another reason to keep your intake moderate.
If you have tried removing peppermint, increasing your nursing sessions, and staying hydrated, but you still feel like your supply is not where it needs to be, it’s time to reach out. We are huge advocates for seeking help early. You don't have to wait until you are in a "crisis" to talk to a professional.
A Virtual lactation consultation can help you identify if there are other factors at play. Sometimes a supply dip is related to:
An IBCLC (International Board Certified Lactation Consultant) can help you create a personalized plan to rebuild your supply and reach your breastfeeding goals. We are here to support you with compassion, not judgment.
It’s also fascinating to look at how different cultures view mint and lactation. In some parts of the world, such as Turkey, certain types of mint are actually used traditionally with the belief that they increase milk supply or improve the flavor.
This highlights the complexity of herbal medicine. The variety of the plant, the soil it grows in, and the way it’s prepared can all change its effect. It also reminds us that the "30/70" rule is real—cultural practices often arise from the experiences of the majority. If 70% of people in a community see no negative effect or feel it helps, that becomes the tradition. At Milky Mama, we respect these cultural traditions while also providing the cautionary data found in modern clinical observations. We want you to have the full picture.
To wrap things up, here are the most important points to remember about peppermint and your milk supply:
Breastfeeding is a journey of a thousand tiny decisions. Whether or not to have that peppermint treat is just one of them. By staying informed and listening to your body, you’re making the best choices for you and your baby.
1. I accidentally drank a whole glass of peppermint tea. Will my milk dry up overnight? It is very unlikely that your milk will dry up completely from one glass of tea. While peppermint can cause a dip in some moms, it is rarely an "all or nothing" situation. The best thing to do is drink plenty of water (or a Milky Mama drink mix), nurse your baby more frequently over the next 24 hours, and avoid more peppermint for a few days.
2. Is spearmint safer than peppermint for breastfeeding? Spearmint also contains menthol, though usually in lower concentrations than peppermint. However, it is still generally classified as an antigalactagogue in the world of herbalism. If you are sensitive to peppermint, it's wise to be cautious with spearmint as well.
3. Can I use peppermint essential oil for my headaches if I don't put it on my chest? Even when applied to your temples or the back of your neck, essential oils are absorbed into your bloodstream. If you are in that sensitive 30% of the population, even this small amount could potentially affect your supply. If you decide to use it, start with a very small, highly diluted amount and monitor your milk output closely.
4. Are there any other herbs I should avoid besides peppermint? Common herbs that are also believed to have lactation-suppressing properties include sage, parsley (in large amounts, like in tabbouleh), and oregano. Like peppermint, these are usually only a concern in therapeutic or very large culinary doses. Always check with a lactation consultant if you're unsure about a specific herb.
Navigating the "dos and don'ts" of breastfeeding can feel like a full-time job on top of already caring for a newborn. We want to remind you that you are doing an amazing job. Whether you’re exclusively nursing, pumping, or doing a bit of both, your dedication to your baby’s nutrition is beautiful.
If you ever feel overwhelmed or worried about your supply, remember that Milky Mama is here to empower you.
