Introduction
You might have heard a whisper in a breastfeeding group or from a well-meaning relative. The warning usually sounds something like this: "Be careful with that peppermint tea; it will dry up your milk!" When you are working hard to maintain your supply, a simple herb like mint can suddenly feel like a major threat. It is completely normal to feel a bit of anxiety about what you eat and drink while nursing.
At Milky Mama, we know that navigating the world of lactation advice can be overwhelming. You want clear, evidence-based answers so you can enjoy your favorite foods without worry. If you want a deeper dive, our Breastfeeding 101 course can help you feel more confident.
This post will explore the relationship between different types of mint and your milk production. We will look at the science behind these claims and help you decide if you need to clear your pantry of all things minty. Our goal is to empower you with the knowledge you need to feed your baby and care for yourself.
The short answer is that while mint is often labeled as something that can lower supply, the real impact depends heavily on the amount you consume and your individual sensitivity.
Understanding Herbs and Lactation
Before we dive into the specifics of mint, it is helpful to understand the two main categories of herbs in the breastfeeding world. There are galactagogues and antigalactagogues. These terms might sound like something out of a science fiction novel, but they are quite simple.
A galactagogue is a substance that may help support or increase milk production. These are often the stars of the show in lactation snacks. On the other hand, an antigalactagogue is a substance that may decrease milk supply. Mint is frequently placed in this second category.
It is important to remember that herbs are not regulated the same way as medications. This means much of what we know comes from traditional use and anecdotal evidence. Anecdotal evidence refers to stories and personal experiences shared by parents over many years. While these stories are valuable, they do not always mean that every person will have the same reaction.
Your milk supply is primarily driven by a process called "supply and demand." This means the more milk you remove from your breasts, the more milk your body will make. Herbs can play a supporting role in this process, but they are rarely the only factor. If your supply is robust and you have a well-established nursing routine, a small amount of an antigalactagogue is unlikely to cause a noticeable change.
The Connection Between Mint and Milk Supply
The concern about mint usually centers around peppermint and its main active component, menthol. Menthol is the ingredient that gives mint its cooling sensation. While many people enjoy the refreshing taste of mint, some lactation experts suggest caution for breastfeeding parents.
Does Peppermint Decrease Milk Supply?
Peppermint is the most common variety of mint associated with a drop in milk production. In the world of herbalism, peppermint is considered a "drying" herb. Historically, it has been used by parents who are ready to wean their babies. They might drink several cups of strong peppermint tea each day to help signal to their bodies that it is time to stop making milk.
However, there is very little clinical research to prove that peppermint definitely reduces supply in all people. Most of the evidence is based on reports from parents who noticed a dip after consuming large amounts. For most people, the occasional peppermint candy or a single cup of tea is not enough to cause a problem.
What About Spearmint?
Spearmint is another popular variety of mint found in gums, teas, and desserts. It contains much less menthol than peppermint. Because the menthol content is lower, spearmint is generally considered less likely to impact your milk supply. If you love the taste of mint but are worried about your supply, spearmint might be a safer choice for your palate.
Menthol: The Active Component
Menthol is a powerful organic compound. It can be found in concentrated forms in essential oils, chest rubs, and certain types of cough drops. Because it is so concentrated in these forms, it may have a stronger effect on your body than a few mint leaves in a salad.
Some parents find that using strong mentholated balms on their chests for congestion can lead to a temporary dip in supply. If you are feeling under the weather, it is a good idea to check the ingredients of your vapor rubs. You might prefer using a menthol-free version or applying it further away from your breasts.
How Much Mint is Too Much?
The most important thing to remember is that the "dose makes the poison." This is an old saying in science that means almost anything can be safe in small amounts but potentially harmful in large ones. For most nursing parents, mint is not a "forbidden food."
If you enjoy a thin mint cookie or a sprig of fresh mint in your water, you likely have nothing to worry about. These items contain very small amounts of the actual herb. The concern really begins when you consume mint in concentrated or therapeutic doses.
High-risk forms of mint consumption include:
- Strong peppermint tea (drinking 3 or more cups per day)
- Peppermint essential oil (ingesting it or applying it directly to the skin)
- Large quantities of peppermint-flavored candies or lozenges
- Concentrated mint tinctures or extracts
If you have a history of low milk supply, you might choose to be more cautious than someone with an oversupply. Every drop counts, and it is okay to play it safe if you are feeling anxious. If you notice your baby acting frustrated at the breast or you are pumping less than usual after eating mint, simply stop consuming it. Most parents find their supply bounces back quickly once the herb is out of their system.
Key Takeaway: Most breastfeeding parents can safely enjoy small amounts of mint in food and drinks. Significant drops in supply are usually only linked to high, concentrated doses like strong teas or essential oils.
Practical Scenarios: Mint in Your Daily Life
It helps to look at real-life situations to see how mint might fit into your day. We encounter mint in many surprising places. Here is how to handle some of the most common scenarios.
Holiday Treats and Seasonal Drinks
During the winter holidays, peppermint is everywhere. From lattes to bark to cookies, it is hard to avoid. You do not have to skip the festivities! A peppermint mocha or a couple of cookies is highly unlikely to impact your supply. These items use flavoring or small amounts of oil that are well within a safe range for most people.
Oral Care Products
Toothpaste and mouthwash almost always contain mint or menthol. These products are completely safe for breastfeeding parents. You are not ingesting large amounts of the herb, and the contact time with your mouth is very short. There is no need to switch to bubblegum-flavored toothpaste unless you simply prefer the taste!
Skincare and Bath Products
Many lotions, foot creams, and shampoos use mint for its cooling and invigorating properties. These are generally safe to use. However, be mindful of where you apply them. Avoid putting strong minty lotions directly on your breasts or nipples. This is not just because of milk supply; the strong smell and cooling sensation might be off-putting to your baby during a nursing session.
Nausea and Digestive Support
Mint is a fantastic natural remedy for an upset stomach or nausea. If you are struggling with digestive issues, a cup of peppermint tea might be exactly what you need. If you only drink it occasionally, it should not harm your supply. If you find you need it daily, you might try ginger tea as an alternative, and our guide on does drinking water help breast milk supply? can help you think through hydration.
Other Herbs That May Impact Your Supply
Mint is not the only herb with a reputation for drying up milk. If you are keeping an eye on your supply, it is helpful to know about a few other common kitchen herbs. Like mint, these are usually only a concern in large, medicinal amounts.
- Sage: This herb is one of the most well-known antigalactagogues. It is frequently used in stuffing and savory dishes. While a little sage in your dinner is fine, sage tea is often used specifically to help stop milk production during weaning.
- Parsley: In very large quantities, such as the amounts found in a traditional tabbouleh salad, parsley might cause a temporary dip for some parents.
- Oregano and Thyme: These are sometimes mentioned in herbal texts as having drying properties, but there is very little evidence to suggest they impact milk supply when used as standard cooking spices.
If you are ever unsure about an herb or a supplement, it is always best to consult with a certified lactation consultant. They can help you weigh the benefits and risks based on your specific situation.
What to Do if Your Supply Dips
If you suspect that your supply has decreased—whether due to mint, stress, or a return to work—do not panic. Our bodies are incredibly resilient. Breasts were literally created to feed human babies, and they are designed to respond to changes.
The first step is to increase the frequency of milk removal. This is the most effective way to signal your body to make more milk. You can do this by:
- Adding an extra nursing session during the day.
- Power pumping (alternating short bursts of pumping with rest for an hour).
- Ensuring you are getting plenty of skin-to-skin time with your baby.
Skin-to-skin contact releases oxytocin, the "love hormone." This hormone is responsible for the let-down reflex, which is the process of your milk flowing out of the breast. When you are relaxed and bonded with your baby, your milk flows more easily.
You should also take a look at your hydration and nutrition. While you do not need a perfect diet to make nutritious milk, your body needs enough calories and water to function at its best. If you have been avoiding certain foods or forgetting to drink water, refocusing on your own wellness can make a big difference.
Ingredients That Support a Healthy Milk Supply
If you want to move away from "drying" herbs and toward ingredients that support your journey, there are many delicious options. At Milky Mama, we focus on using ingredients that have been used for generations to support breastfeeding parents.
Some of the most popular galactagogues include:
- Oats: These are a staple for many nursing parents. They are a great source of iron and fiber.
- Brewer's Yeast: This is a traditional ingredient used in many lactation treats. It is rich in B vitamins and minerals.
- Flaxseed: These seeds provide healthy fats and phytoestrogens, which may support lactation.
- Moringa: This nutrient-dense leaf is gaining popularity for its ability to support a healthy milk supply.
We include these ingredients in our favorite products. For example, our Emergency Lactation Brownies are a delicious way to incorporate oats, flax, and brewer's yeast into your day.
We also offer herbal supplements like Pumping Queen™, which is carefully formulated without the use of certain herbs that might cause issues for some parents.
Lady Leche™ is another option for parents looking for targeted support.

When to Use Mint on Purpose
There may come a time in your breastfeeding journey when you want your milk supply to decrease. This process is called weaning. Whether you are weaning because your baby is older or because it is the right choice for your mental health, mint can be a helpful tool.
If you are looking to dry up your milk supply comfortably, you can try:
- Drinking 2–4 cups of strong peppermint tea per day.
- Using sage in your cooking or as a tea.
- Applying cold cabbage leaves to your breasts to reduce swelling.
- Reducing nursing or pumping sessions slowly over several weeks.
Weaning can be an emotional time, and it is important to be gentle with yourself. Using herbs like mint can help make the physical transition a bit smoother by reducing the risk of engorgement or mastitis.
Action Steps for Managing Your Diet and Supply
If you are worried about how your diet is affecting your baby, take these simple steps to find peace of mind. You are doing an amazing job, and a little bit of planning can go a long way.
- Keep a Log: If you are worried about a specific food, write down what you ate and how your pumping or nursing sessions went for the next 24 hours.
- Focus on Moderation: Enjoy your minty treats in small amounts rather than consuming them all day long.
- Stay Hydrated: Drink water whenever you feel thirsty. Keep a water bottle nearby during every nursing or pumping session.
- Check Your Labels: Briefly look at the ingredients of your supplements and teas to ensure they align with your goals.
- Trust Your Body: You are the expert on your own baby and your own body. If something feels off, listen to that intuition.
Key Takeaway: Knowledge is power. By understanding which herbs support supply and which ones might hinder it, you can make the best choices for your unique breastfeeding journey.

FAQ
Can I drink peppermint tea while breastfeeding?
Yes, you can generally enjoy a cup of peppermint tea occasionally without it affecting your milk supply. Most issues with supply only occur when a parent drinks several strong cups per day or uses peppermint essential oil. If you notice a dip in your production after drinking it, you may want to switch to a different herbal tea like ginger or chamomile.
Does mint in toothpaste lower milk supply?
No, the mint found in toothpaste and mouthwash will not lower your milk supply. You are not swallowing the product, and the amount of menthol that enters your system through your gums is extremely negligible. You can continue your normal oral hygiene routine without any concerns for your breastfeeding journey.
Is spearmint safer than peppermint for milk supply?
Spearmint is generally considered safer for milk supply because it contains significantly less menthol than peppermint. Menthol is the specific component in mint that is thought to have "drying" properties. If you love mint flavor but want to be extra cautious, choosing spearmint-flavored items is a great compromise.
How long does it take for mint to leave your system?
If you consumed a large amount of mint and noticed a temporary dip in your supply, the effects typically wear off within 24 to 48 hours. Once you stop consuming the herb and continue to nurse or pump frequently, your body should return to its normal production levels. If you’re still concerned, our guide on what to do when milk supply is low can help.
