Introduction

Sitting down with a warm cup of tea is often the only moment of peace a new parent gets all day. Whether it is a morning ritual to wake up or a nighttime routine to wind down, tea is a staple in many households. However, once you start breastfeeding, every snack and sip comes with a side of worry. You might find yourself staring at your mug and wondering if the ingredients inside could be impacting your milk production.

The short answer is that most teas are perfectly safe, but there are some specific herbs and caffeine levels you should watch out for. At Milky Mama, we know that navigating the "what can I eat and drink" list can feel overwhelming when you are already exhausted. Our goal is to provide you with the facts so you can enjoy your tea time without the stress.

In this article, we will explore which teas might decrease your supply, how caffeine plays a role, and which herbal blends are actually helpful for lactation. We want you to feel empowered and informed about your choices. Understanding how different ingredients interact with your body is the first step toward a confident breastfeeding journey.

The Relationship Between Tea and Lactation

For most people, tea is a gentle way to stay hydrated. Since milk production relies heavily on your fluid intake, drinking tea can actually be a helpful part of your daily routine. However, the word "tea" covers a huge variety of plants, roots, and leaves. Some of these are known as galactagogues—substances that may help promote milk production—while others are traditionally used to do the opposite.

When we talk about tea decreasing milk supply, we are usually looking at two main factors: high caffeine content and specific anti-galactagogue herbs. Anti-galactagogues are substances that may reduce or dry up milk secretions. While one cup of a specific tea is unlikely to cause a dramatic drop, consistent consumption of certain blends might have an impact.

It is also important to remember that every body responds differently. What affects one person’s supply might not affect another’s. However, if you have noticed a dip in your output or your baby seems extra fussy, looking at your tea cabinet is a great place to start troubleshooting.

Can Caffeine in Tea Affect Your Supply?

Most true teas—like black, green, white, and oolong—come from the Camellia sinensis plant and naturally contain caffeine. Caffeine is a stimulant that can pass into your breast milk in small amounts. While caffeine itself does not directly "dry up" milk, it can have indirect effects on your breastfeeding experience.

The Stress and Let-Down Connection

High levels of caffeine can sometimes lead to feelings of jitteriness or anxiety. In some parents, this can interfere with the let-down reflex. The let-down reflex is the physiological response that causes milk to be released from the milk ducts and flow toward the nipple. This process is heavily influenced by oxytocin, often called the "love hormone." Stress and high adrenaline (which can be triggered by too much caffeine) can sometimes inhibit oxytocin, making it harder for your milk to flow effectively.

Baby’s Behavior and Feeding Frequency

If you consume a large amount of caffeine, your baby might become more alert, restless, or fussy. A baby who is too wired to settle down for a good nursing session might not drain the breast effectively. Since milk production works on a supply and demand basis, if the breast is not being emptied frequently, your body may start to slow down production.

Since milk removal is central to maintaining production, this guide to increasing milk supply through breastfeeding and pumping can provide additional support.

How Much Is Too Much?

Most health experts suggest limiting caffeine to about 200 to 300 milligrams per day while breastfeeding. For context:

An 8-ounce cup of black tea has about 40–70mg of caffeine.
An 8-ounce cup of green tea has about 25–45mg of caffeine.
A standard cup of coffee can have 95–150mg of caffeine.

Most nursing parents find they can enjoy two or three cups of tea a day without any issues. If you notice your baby is having trouble sleeping or seems unusually irritable, you might try switching to decaf versions or herbal alternatives.

Key Takeaway: Moderation is key with caffeinated teas. While a few cups are usually fine, excessive caffeine can lead to stress or a fussy baby, both of which can indirectly impact how well your milk flows.

Herbs That May Decrease Milk Supply

There are certain herbs that have been used for centuries by people who are looking to wean or reduce an oversupply. These are the ingredients you want to be cautious with if your goal is to maintain or increase your milk production.

Peppermint

Peppermint is perhaps the most well-known "anti-galactagogue." Many breastfeeding parents find that a peppermint candy or a single cup of tea occasionally doesn't hurt. However, large amounts of peppermint—especially in concentrated forms like essential oils or strong medicinal teas—can potentially decrease milk supply. If you are struggling with low supply, it is a good idea to avoid peppermint tea until your levels are where you want them to be.

Sage

Sage is often used traditionally to help dry up milk during weaning. It contains compounds that can be very effective at reducing secretions. While using a little sage in your Thanksgiving stuffing is likely fine, drinking sage tea or taking sage supplements can lead to a noticeable dip in production.

Parsley

Similar to sage, parsley in high medicinal doses is known for its ability to reduce milk supply. A garnish on your dinner plate is no cause for alarm, but a "parsley tea" or a large parsley-based salad (like tabbouleh) every day might be something to reconsider if you are worried about your supply.

Jasmine

In some cultures, jasmine flowers are used to help suppress lactation. While jasmine green tea is popular and generally has a low concentration of the flower, those who are very sensitive might want to keep an eye on how it affects them.

Are Herbal Teas Safe for Breastfeeding?

Herbal teas are not technically "tea" because they don't come from the tea plant. They are infusions made from dried fruits, flowers, or herbs. Many of these are wonderfully supportive for breastfeeding parents.

For example, many "lactation teas" use ingredients like:

Blessed Thistle: Often used to support milk flow.
Nettle: High in iron and other minerals that support maternal wellness.
Alfalfa: Packed with vitamins and minerals.
Red Raspberry Leaf: Known for supporting uterine health and providing a boost of nutrients.

We often recommend looking for high-quality blends that focus on these supportive herbs. Our Lady Leche™ herbal supplement is formulated with organic herbs to support milk production for those who prefer a concentrated option over a cup of tea.

You can also explore Milky Mama’s lactation supplements when comparing concentrated herbal support options.

Hydration and Your Milk Supply

It is a common myth that you need to drink gallons of water to make milk. While you don't need to over-hydrate, you do need to stay adequately hydrated. Tea counts toward your daily fluid intake!

If you find plain water boring, herbal teas can be a great way to meet your hydration goals. When you are hydrated, your body can function at its best, which includes the energy-intensive process of making milk. We often suggest keeping a water bottle or a cup of tea nearby every time you sit down to nurse. This helps you remember to drink and keeps your thirst at bay.

If you are looking for a refreshing way to stay hydrated that also supports lactation, our Pumpin Punch™ drink mix or lactation drink mixes are excellent alternatives to traditional tea. They provide hydration plus supportive ingredients without the worry of "supply-killing" herbs.

How to Tell if Your Supply is Actually Low

Sometimes, we blame the tea when our supply isn't actually the problem. It is very common for parents to worry about their milk levels, but many times, the body is doing exactly what it should.

For more guidance, read about the signs that milk supply may actually be low.

The "Soft Breast" Myth

In the early weeks, your breasts might feel very full or even engorged. As your supply regulates (usually around 6 to 12 weeks), your breasts will start to feel softer. This does not mean your milk is gone! It just means your body has figured out exactly how much milk your baby needs and is no longer overproducing.

Cluster Feeding

If your baby is nursing every hour, it doesn't always mean they are hungry because you are low on milk. This is often "cluster feeding," which is your baby's way of signaling your body to make more milk for an upcoming growth spurt. It is a normal, healthy part of the process.

Learn more about cluster feeding and how it can affect milk supply.

Real Signs to Watch For

If you are concerned that tea or anything else is decreasing your supply, look for these indicators:

Weight Gain: Is your baby gaining weight according to their growth curve?
Wet Diapers: Is your baby having at least 6 heavy wet diapers in a 24-hour period?
Active Swallowing: Can you hear or see your baby swallowing during a feeding?

If these things are on track, you are likely doing an amazing job, and your occasional cup of tea is probably not causing any issues.

Action Steps for Tea-Loving Moms

If you love your tea but want to be extra careful with your milk supply, here is a quick checklist to follow:

Check the ingredients: Avoid teas where peppermint or sage are the main ingredients.
Watch the clock: Try to drink caffeinated tea right after a nursing session to give the caffeine time to peak and decline in your system before the next feed.
Limit the quantity: Stick to 2–3 cups of caffeinated tea per day.
Go herbal: Explore breastfeeding-safe herbal infusions like rooibos, ginger, or chamomile.
Monitor your baby: If the baby seems extra restless, try cutting back on caffeine for a few days to see if their behavior changes.
Listen to your body: If you notice a dip in supply after starting a new tea, stop drinking it and see if your supply bounces back.

Supporting Your Supply Naturally

If you have accidentally consumed something that decreased your supply, don't panic. The best way to build it back up is through frequent milk removal. This tells your body that the demand has increased, and it needs to ramp up production.

You can also incorporate snacks and drinks designed to support lactation. Our Emergency Brownies are a favorite for many moms who need a quick and delicious boost. They are packed with oats and flaxseed, which are traditional galactagogues that many parents find very helpful.

You can browse additional lactation snacks and treats for other supportive options.

Remember, breastfeeding is a journey with many ups and downs. One cup of tea is rarely enough to derail your goals. You deserve to enjoy small comforts like a warm beverage while you care for your little one.

Conclusion

While most tea does not decrease breast milk supply, it is important to be mindful of what is in your cup. High amounts of caffeine can lead to a fussy baby or a suppressed let-down reflex, and certain herbs like peppermint, sage, and parsley can potentially dry up milk if consumed in large quantities. By sticking to moderation and choosing supportive herbal blends, you can safely enjoy your favorite tea rituals.

Limit caffeine to 200-300mg per day.
Avoid large amounts of peppermint and sage.
Stay hydrated with supportive fluids like water or lactation-friendly drinks.

FAQ

Does green tea decrease milk supply?

Green tea does not directly decrease milk supply, but it does contain caffeine. If you drink it in very large quantities, the caffeine could potentially make your baby fussy or interfere with your let-down reflex. Stick to a couple of cups a day, and you should be just fine.

Can I drink peppermint tea while breastfeeding?

It is best to use caution with peppermint tea if you are worried about your supply. While a single cup may not have a huge effect, peppermint is a known anti-galactagogue and is often used to help dry up milk during weaning. If your supply is already low, you may want to avoid it entirely.

What teas are best for increasing milk supply?

Teas containing herbs like blessed thistle, alfalfa, nettle, and red raspberry leaf are often recommended for breastfeeding parents. These herbs are rich in nutrients and have traditionally been used to support lactation and maternal health. Always check with a lactation consultant if you have questions about specific herbal blends.
