Introduction
Finding a moment of peace with a warm mug in your hands can feel like a luxury when you are caring for a new baby. For many parents, tea is a daily ritual that provides comfort, warmth, and a much-needed caffeine boost. However, if you are breastfeeding or pumping, you might find yourself pausing before that second or third cup. You may have heard whispers in parenting groups or read online that certain teas could potentially impact your milk production.
It is completely normal to feel protective of your milk supply. We know how much work goes into every ounce. At Milky Mama, we receive questions every day from parents wondering if their favorite beverage is helping or hurting their lactation journey. For a stronger foundation, our Breastfeeding 101 course is a helpful place to start.
This article will explore the specific herbs that might lower supply and look at how caffeine affects your milk. We will also discuss which teas are considered safe and how you can use certain blends to support your lactation goals. Our goal is to give you the information you need to enjoy your tea while keeping your supply right where you want it to be.
Understanding Tea and Lactation
When we talk about tea, we are actually talking about two very different categories of drinks. The first is traditional tea made from the Camellia sinensis plant, which includes black, green, white, and oolong varieties. The second category is herbal tea, which is an infusion of various roots, barks, leaves, or flowers.
In the world of lactation, we often talk about "galactagogues." This is a fancy term for any substance that can help support or increase milk production. On the flip side, there are "antigalactagogues." These are substances that may reduce or dry up your milk supply. While most common teas are perfectly fine, a few specific herbal ingredients fall into that second category.
Most parents do not need to give up tea entirely. Instead, the focus should be on moderation and ingredient awareness. If you want more ideas for beverages that fit a lactation routine, browse our lactation drink mixes.
The Role of Caffeine in Milk Supply
One of the biggest concerns for breastfeeding parents is caffeine. Traditional teas like Earl Grey, English Breakfast, and Matcha all contain caffeine. While caffeine does not directly "stop" the production of milk, it can have indirect effects on your breastfeeding experience.
How Much Caffeine Is Too Much?
Most healthcare providers and lactation experts suggest limiting caffeine to about 200 to 300 milligrams per day. For a closer look at how caffeine fits into breastfeeding, see our coffee and breastfeeding guide. For reference, an average cup of black tea contains about 40 to 70 milligrams. This means most parents can safely enjoy two or three cups of tea without reaching that limit.
However, every baby reacts differently to caffeine. A small amount of the caffeine you consume does pass into your breast milk. Because newborns cannot metabolize caffeine as quickly as adults, it can build up in their systems. If your baby becomes fussy, jittery, or has trouble sleeping, it might be a sign that your tea habit is affecting them.
Caffeine and Dehydration
There is a common myth that caffeine causes severe dehydration, which then leads to a low milk supply. While caffeine is a mild diuretic (meaning it makes you pee more), it generally does not cause dehydration in moderate amounts. If you are drinking enough water throughout the day, a few cups of caffeinated tea are unlikely to impact your hydration levels enough to hurt your supply.
The Impact on the Let-Down Reflex
Stress and anxiety can sometimes interfere with your let-down reflex. The let-down reflex is the hormone-driven process that releases milk from the milk ducts and makes it available to your baby or pump. If you are overly caffeinated and feeling "wired" or anxious, it might take longer for your milk to flow. This can lead to frustration for both you and your baby, but it is usually a temporary issue.
Key Takeaway: Moderation is the most important factor when consuming caffeinated tea. Keep an eye on your baby's behavior and your own stress levels to find the right balance.
Herbs That May Decrease Milk Supply
This is the area where tea can actually cause a noticeable drop in milk production. Certain herbs have been used for centuries to help parents who are ready to wean or who are dealing with an oversupply. These are the "antigalactagogues" we mentioned earlier.
Peppermint and Menthol
Peppermint is one of the most common ingredients in herbal tea blends. While it is great for digestion, large amounts of peppermint or menthol may decrease milk supply for some people. This typically happens when someone consumes very strong peppermint tea several times a day or uses peppermint essential oils.
A single peppermint candy or a light cup of tea is usually not enough to cause a problem. However, if you are struggling with a low supply, it is best to avoid peppermint until your production is back where you want it to be.
Sage
Sage is perhaps the most well-known herb for drying up milk. It contains natural compounds that can decrease lactation quite effectively. In fact, many lactation consultants recommend sage tea to parents who need to stop breastfeeding quickly or who are suffering from painful engorgement during weaning. If your goal is to maintain or increase your supply, you should avoid sage in your tea and your cooking.
Parsley
While you usually find parsley on a dinner plate, it is sometimes included in herbal detox teas or green tea blends. Like sage, parsley is considered an antigalactagogue when consumed in large, concentrated amounts. Using a little bit as a garnish is perfectly safe, but avoid any tea that lists parsley as a primary ingredient.
Jasmine
Some traditional cultures have used jasmine flowers to help suppress lactation. While the research is limited, some breastfeeding parents report a dip in supply after consuming large amounts of jasmine tea. If you love the floral scent of jasmine, you might want to enjoy it in smaller quantities or switch to a different floral tea like chamomile or lavender.
Safe and Supportive Teas for Breastfeeding
The good news is that there are many teas that are not only safe but may actually help you reach your breastfeeding goals. Many herbal blends are designed specifically to support lactation by using safe, time-tested ingredients.
Red Raspberry Leaf
Red raspberry leaf is a favorite in the midwifery and lactation world. It is rich in vitamins and minerals, including iron, calcium, and magnesium. It is often recommended during pregnancy to tone the uterus and during postpartum to help the body recover. While it isn't a direct milk booster for everyone, it supports overall uterine health and provides essential nutrients that help your body function at its best.
Nettle Tea
Stinging nettle is a nutritional powerhouse. It is high in iron and chlorophyll, which can be very helpful for parents recovering from childbirth. Many people find that the high mineral content in nettle tea provides a gentle boost to their energy and their milk supply. It has a "green," earthy taste that pairs well with a little bit of honey.
Blessed Thistle and Alfalfa
These two herbs are common ingredients in lactation supplements and teas. They are believed to support the hormones responsible for milk production. When combined with frequent nursing or pumping, they can be a helpful tool for maintaining a healthy supply.
At Milky Mama, we use high-quality herbal ingredients in supplements like Lady Leche™ and Pumping Queen™ to help parents feel confident in their milk production.
Common Safe Options
If you are looking for a standard tea that won't hurt your supply, these are generally considered safe in moderate amounts:
- Chamomile: Great for relaxation and sleep.
- Ginger: Excellent for digestion and soothing an upset stomach.
- Rooibos: A naturally caffeine-free red tea that is high in antioxidants.
- Fruit-based teas: Most teas made from dried fruits (like hibiscus or berry blends) are safe and hydrating.
The Importance of Hydration
One reason people worry about tea and milk supply is the focus on hydration. Producing milk requires a significant amount of fluid. If you are replacing water with high amounts of caffeinated tea, you might not be getting the pure hydration your body needs.
However, tea can actually count toward your daily fluid intake. If you enjoy herbal, caffeine-free teas, they can be a tasty way to stay hydrated. If you find plain water boring, herbal tea is a much better alternative than sugary sodas or excessive coffee.
We often recommend mixing up your hydration routine. In addition to water and tea, many parents find success with our hydration drinks. Products like Milky Melon™ and Pumpin' Punch™ provide the hydration your body needs along with ingredients that support lactation. Staying hydrated shouldn't feel like a chore, and having a variety of drinks can help you meet your daily goals.
Quick Tips for Tea Drinkers:
- Check the labels: Always read the ingredient list on herbal tea blends to ensure they don't contain sage or high amounts of peppermint.
- Watch the clock: If you notice your baby is extra fussy in the evening, try moving your caffeinated tea to earlier in the morning.
- Stay balanced: For every cup of caffeinated tea, try to drink one or two extra glasses of plain water.
- Monitor your body: Pay attention to your "fullness" levels and your pumping output when trying a new tea.
How to Tell if Your Supply Is Actually Dropping
Sometimes, we worry that our supply is dropping when it is actually just "regulating." In the first few weeks, your breasts might feel very full or even engorged. As time goes on, your body becomes more efficient at making exactly what your baby needs. This means your breasts might feel softer, and you might stop leaking. This is usually a sign of a healthy, established supply, not a decrease.
If you are concerned that tea or anything else is lowering your supply, look for these reliable signs:
- Diaper count: Your baby should be having at least 6 heavy wet diapers in a 24-hour period.
- Weight gain: Your baby should be following their growth curve at their pediatrician appointments.
- Swallowing: You should be able to hear or see your baby swallowing during feedings.
If you want a more detailed checklist, our 7 signs your milk supply is actually low guide is a helpful reference. If your baby is meeting these milestones, your tea consumption is likely not causing a problem. If you are pumping and notice a significant, sustained drop in ounces that correlates with a new tea habit, it might be time to switch to a different blend.
When to Seek Professional Support
If you have cut out the "risky" herbs and moderated your caffeine but still feel your supply is low, it is important to reach out for help. Sometimes, supply issues are related to a baby's latch or a medical condition rather than what you are eating or drinking.
A Certified Lactation Consultant (IBCLC) can help you create a plan to protect your supply. If you want personalized guidance, our breastfeeding help page is a great next step. They can look at your nursing or pumping schedule and help you identify any gaps. You don't have to navigate these challenges alone. We offer virtual consultations and support through our community to help you feel empowered on your journey.
What to Do if You Drank the "Wrong" Tea
Don't panic if you realized you just finished a giant mug of sage or peppermint tea. One cup is very unlikely to dry up your milk supply overnight. The body is resilient, and milk production is primarily driven by "supply and demand." This means the more milk you remove from your breasts, the more milk your body will make.
If you are worried that an herbal tea affected you, the best thing you can do is increase the frequency of your nursing or pumping sessions for the next 24 to 48 hours. This sends a strong signal to your body to ramp up production. You can also add in some lactation-supportive snacks. Our Emergency Lactation Brownies are a popular choice for parents who want a delicious way to support their supply after a dip.
Lifestyle Factors That Matter More Than Tea
While it is good to be mindful of what you drink, other factors usually have a much bigger impact on milk supply than a cup of tea. If you are feeling stressed about your supply, check in on these three things:
If you are building a pumping routine, our How to Add Pumping While Breastfeeding guide can be a helpful companion.
1. Frequency of Milk Removal
The most common cause of a supply drop is not removing milk often enough. If you start going longer between sessions or if your baby is sleeping longer stretches, your supply may naturally dip. Ensure you are nursing or pumping at least 8 to 12 times in a 24-hour period in the early months.
2. Stress and Sleep
We know that "get more sleep" is difficult advice for a new parent. However, extreme exhaustion and high stress levels can increase cortisol, which can sometimes interfere with the let-down reflex. Even a 20-minute nap or five minutes of deep breathing while you drink your (safe) tea can help your body stay in a relaxed state for milk production.
3. Caloric Intake
Your body needs extra calories to produce milk. If you are skipping meals or trying to lose weight too quickly, your milk supply might suffer. Focus on nutrient-dense foods and keep easy snacks on hand.
Key Takeaway: Tea is rarely the sole cause of a low milk supply. Always look at the big picture of your nursing routine and overall health first.
A Note on Supplements and Safety
When you are looking for ways to support your supply, you might be tempted to try every herbal supplement on the market. It is important to remember that herbs are powerful. Just because something is "natural" does not mean it is right for everyone.
Always talk to your healthcare provider or a lactation professional before starting a new herbal regimen. Some herbs can interact with medications or may not be suitable if you have certain health conditions like thyroid issues or diabetes.
This product is not intended to diagnose, treat, cure, or prevent any disease. Consult with your healthcare provider for medical advice.
Our herbal lactation supplements, such as Pump Hero™, are designed with safety and efficacy in mind. We use ingredients that have a long history of supporting breastfeeding parents. When used alongside a consistent nursing or pumping schedule, these can be a wonderful part of your lactation toolkit.
Practical Steps for the Tea-Loving Parent
If you want to keep enjoying your tea while breastfeeding, follow this simple plan to ensure your supply stays strong:
- Choose Caffeine-Free Often: Stick to herbal infusions like rooibos, ginger, or fruit teas for the majority of your cups.
- Limit Peppermint and Sage: Check your "Sleepytime" or "Tummy Soothing" blends for these ingredients.
- Watch Your Baby: If they seem extra awake or fussy, scale back on the black and green teas.
- Focus on Nutrient-Dense Sips: Choose teas like nettle or red raspberry leaf that provide minerals your body needs.
- Prioritize Removal: Don't let your tea break replace a feeding or pumping session.
By being a little bit selective about your tea choices, you can continue to enjoy this comforting habit without any stress. Breastfeeding is a marathon, and finding small ways to treat yourself—like a perfect cup of tea—can make the journey much more sustainable.

FAQ
Does peppermint tea dry up milk supply?
In large amounts, peppermint and menthol are known to potentially reduce milk supply. While a single cup of weak peppermint tea or a peppermint candy is usually fine, it is best to avoid drinking it multiple times a day if you are concerned about your production. If you notice a dip in supply after consuming peppermint, try switching to a different herbal tea like ginger or chamomile.
Is green tea safe for breastfeeding?
Yes, green tea is generally considered safe for breastfeeding parents when consumed in moderation. It does contain caffeine, so it is important to keep your total daily caffeine intake under 300mg. Some babies may be sensitive to the caffeine in green tea, so watch for signs of fussiness or disrupted sleep patterns in your little one.
Can I drink sage tea while breastfeeding?
Sage is one of the few herbs that is highly effective at drying up milk supply. It is often recommended by lactation consultants specifically for weaning or to help with an extreme oversupply. If you want to maintain your current milk production, it is best to avoid sage tea and using large amounts of sage in your cooking.
How much caffeine can I have while breastfeeding?
Most experts recommend limiting caffeine to about 2 to 3 cups of coffee or tea per day, which is roughly 200 to 300 milligrams of caffeine. Every baby has a different tolerance level for caffeine. If your baby seems unusually irritable or has trouble staying asleep, you may want to reduce your intake to see if their behavior improves.
