Finding a moment for a peppermint latte or a soothing cup of tea can feel like a tiny vacation during a busy day of parenting. However, if you have spent any time in breastfeeding circles, you may have heard whispers that mint is something to avoid. At Milky Mama, we know that worrying about your milk supply can be incredibly stressful, and you want to make sure every bite and sip supports your breastfeeding goals.
This post will explore the relationship between mint and milk production, helping you understand when it is safe to enjoy and when you might want to be cautious. We will look at the science behind menthol and provide practical tips for maintaining a robust supply. While many parents can enjoy a minty treat without issue, understanding how certain herbs affect your body is a key part of your breastfeeding journey. Our goal is to empower you with the facts so you can feed your baby with confidence.
When we talk about mint and breastfeeding, we are usually talking about peppermint (Mentha piperita). While there are many varieties of mint, such as spearmint or chocolate mint, peppermint contains the highest concentration of menthol. This is the organic compound responsible for that cooling sensation and strong aroma.
For generations, peppermint has been used as a natural way to help reduce an oversupply of milk or to assist with the weaning process. In the world of lactation, we call substances that may reduce milk supply "anti-galactagogues." While the evidence is largely based on tradition and anecdotal reports from parents, there is enough collective experience to suggest that high doses of peppermint can indeed impact production for some people.
It is important to remember that most herbs are dose-dependent. This means that a tiny bit of mint in your toothpaste is very different from drinking several quarts of strong peppermint tea every day. Most breastfeeding parents find that they do not need to scrub their diets of every trace of mint. However, if you are already navigating a low milk supply, being mindful of your intake is a smart move. You can also review this guide to signs that your milk supply may actually be low.
The short answer is: it can, but it usually depends on how much you are consuming and how sensitive your body is to the herb. There is no magic "off switch" for milk production, but peppermint is one of the few culinary herbs that lactation consultants often suggest limiting if a parent is struggling with supply.
Menthol is the active ingredient in peppermint that is thought to be responsible for the dip in supply. Some studies on animals and in laboratory settings have shown that high concentrations of menthol can suppress the activity of the cells that produce milk. In humans, menthol is absorbed into the bloodstream and can even be detected in small amounts in breast milk.
For the average person, the amount of menthol found in a single peppermint patty or a stick of gum is negligible. However, concentrated forms are more likely to cause a noticeable change. These include:
Every body is unique. Some parents can drink peppermint tea daily and never see a change in their pumping output. Others may notice a significant "dip" after eating a bowl of mint chocolate chip ice cream. Roughly 30% of breastfeeding parents report some level of sensitivity to peppermint when consumed in therapeutic amounts.
If you have a history of oversupply or a very stable milk production, you are less likely to be affected by a small amount of mint. If you are in the early weeks of breastfeeding while your supply is still establishing, your body may be more susceptible to these external influences.
Key Takeaway: While a single minty treat is unlikely to dry up your milk, consuming high concentrations of peppermint or menthol can lead to a temporary decrease in supply for sensitive individuals.
You might be surprised at how many places mint hides in a standard US diet and medicine cabinet. If you are concerned about your supply, it helps to be aware of these common sources.
Peppermint tea is a common remedy for digestive issues, but it is also one of the most frequent culprits for a "mint-related" supply drop. During the winter months, peppermint-flavored lattes and hot chocolates are everywhere. An occasional seasonal drink is usually fine, but if you are drinking several large peppermint lattes a week, it might be worth monitoring your supply.
Strong peppermint candies are designed to have a high concentration of peppermint oil to freshen breath. Because these are often consumed one after another, the cumulative dose of menthol can become quite high. If you find yourself reaching for a tin of strong mints throughout the day, consider switching to a fruit-flavored alternative for a while.
Almost all toothpaste and mouthwash brands use peppermint or menthol for flavor. Generally, the amount you are exposed to during brushing and rinsing is so small—and since you aren't swallowing it—that it is not considered a risk to milk supply. You do not need to switch to "toddler" toothpaste unless you are exceptionally sensitive.
Menthol is a primary ingredient in many chest rubs (like Vicks Vaporub), cough drops, and nasal inhalers. While these are great for clearing congestion, they do provide a steady dose of menthol. If you are sick and need to use these products, just keep an eye on your baby’s satisfaction at the breast.
If you use a chest rub, be sure to apply it in a way that the baby does not come into direct contact with the product or the strong vapors during nursing. We recommend washing your hands thoroughly after application.
If you just realized you ate a whole bag of Thin Mints and you are starting to panic, take a deep breath. A dip in supply is often temporary, and for many, the "dip" is more in their mind than in their breasts. Before concluding that the mint has caused a problem, look for these objective signs:
It is normal for breasts to feel softer as your supply regulates around 6 to 12 weeks postpartum. This is not a sign of low supply; it is a sign that your body has become efficient at making milk on demand.
Mint isn't the only herb that has a reputation for "drying things up." If you are trying to maintain a high supply, you may want to use caution with these other culinary items as well.
Sage is perhaps the most potent "dry-up" herb available in most kitchens. It is frequently used by parents who are ready to wean or those who are suffering from painful oversupply. While a little bit of sage in a Thanksgiving stuffing is usually okay, sage tea or concentrated supplements can have a very rapid effect on milk production.
Small amounts of parsley used as a garnish are perfectly safe. However, eating large quantities—such as in a traditional Tabbouleh salad—can act as a diuretic and may reduce milk volume. Like mint, this is usually only an issue when consumed in large, medicinal amounts.
These herbs are less commonly linked to supply issues, but some herbalists suggest that in very high, concentrated doses (like essential oils or tinctures), they could have a mild suppressing effect. For normal cooking, there is no need to worry about the oregano on your pizza.
While not an herb, it is a common myth that beer increases milk supply. In reality, alcohol can inhibit your let-down reflex—the process where your body releases milk from the ducts. This makes it harder for the baby to get the milk that is already there, which can lead to a decrease in supply over time if the breasts aren't being emptied effectively.
If you have noticed a decrease in your production after a "peppermint incident," do not lose hope. Milk supply is a dynamic system based on supply and demand. In most cases, you can bring your numbers back up within a few days by following a few simple steps.
The first step is the most obvious: stop consuming the peppermint or menthol source. Once the menthol leaves your system, your body’s natural lactation hormones can usually get back to work without interference.
The most effective way to tell your body to make more milk is to remove milk more frequently.
For additional ideas, read this guide to supplementing breastfeeding with pumping.
While you don't need to over-hydrate, staying adequately thirsty-quenched is important. If you’ve been drinking mint tea, swap it out for water or a lactation-supporting drink. Our Pumpin’ Punch™ drink mix or lactation drink mixes are great options that provide hydration along with ingredients designed to support lactation.
Sometimes, a little extra help from Mother Nature can make the recovery process faster. Our Emergency Brownies are one of our most-loved lactation treats, packed with oats, brewer's yeast, and flaxseed to help support supply when you’ve hit a bump in the road. We also offer herbal supplements like Pumping Queen™ or Lady Leche™ for those who prefer a concentrated herbal boost.

What to Do Next:
- Identify and remove any strong sources of peppermint from your daily routine.
- Add an extra pumping session or a "dream feed" to increase demand.
- Monitor baby’s wet diapers and weight gain to ensure they stay on track.
- Reach out to a certified lactation consultant if supply doesn't bounce back within a week.
Sometimes, mint doesn't actually lower the amount of milk you are making; it just makes it harder for the milk to come out. The let-down reflex is a complex neurological and hormonal response. When your baby sucks at the breast, it sends a signal to your brain to release oxytocin. This hormone causes the small muscles around the milk-producing cells to contract, pushing the milk into the ducts.
If you are stressed because you are worried about your supply, or if you are consuming high amounts of menthol, that reflex can be slightly delayed. This can make a baby frustrated, leading them to pull away, which a parent then interprets as "I have no milk."
Creating a calm environment for feeding—using a warm compress on the breast and practicing deep breathing—can help overcome a sluggish let-down. Remember, your body was literally created to feed your baby, and it is very good at doing its job when given the right support.
While a temporary dip from a peppermint mocha is usually just a minor "speed bump," it is important to know when to seek professional help. If you notice any of the following, please contact a lactation consultant or your pediatrician:
At Milky Mama, we believe that every drop counts, and your well-being matters just as much as the baby's. You don't have to navigate these challenges alone. Whether you need a virtual consultation with an IBCLC or just a community of moms who have "been there," support is available.
The world of breastfeeding is full of "don'ts," and it can feel overwhelming to keep track of every herb and spice. To keep it simple, here is the bottom line on mint:
Breastfeeding is natural, but it doesn't always come naturally. It is a learning process for both you and your baby. If you accidentally had some peppermint, don't beat yourself up. You're doing an amazing job, and your body is incredibly resilient.
While mint—specifically peppermint—does have the potential to lower milk supply, it is rarely a reason for panic. For most breastfeeding families, moderation is the key. You can likely enjoy your favorite minty treats occasionally without any negative impact on your breastfeeding journey. However, if you are working hard to build or maintain your supply, being cautious with high-menthol products is a wise strategy.
You’ve got this, mama! Whether you’re nursing, pumping, or a bit of both, we are here to support you with the education and products you need to reach your goals. For an extra boost of confidence and supply support, consider trying our Pumpin' Punch™ or browsing our lactation treats at Milky Mama. Every journey is unique, and we are honored to be a part of yours.

For most parents, the amount of peppermint oil used to flavor ice cream is very small and unlikely to impact milk supply. Unless you are extremely sensitive to menthol, enjoying a serving or two of mint ice cream is generally considered safe. If you are already struggling with a very low supply, you might choose to monitor your output afterward just to be safe.
A single cup of peppermint tea is very unlikely to "dry up" your milk supply completely. Peppermint usually affects supply when consumed in large, frequent doses or very high concentrations. However, if you notice a slight dip after one cup, simply stop drinking the tea and increase your nursing or pumping sessions to bring your supply back up.
Vicks Vaporub contains menthol, which can potentially lower milk supply if used in large amounts or applied near the breasts. It is also important to ensure the baby does not inhale the strong vapors directly or touch the product on your skin. If you need to use it, apply a small amount away from the chest area and wash your hands thoroughly after use.
Most parents see their milk supply return to normal within 24 to 72 hours after they stop consuming peppermint. The recovery time can be faster if you increase the frequency of nursing or add a few power-pumping sessions to stimulate production. Staying hydrated and resting can also help your body bounce back more quickly.
