Introduction
Settling into a quiet moment with a warm cup of tea can feel like a lifeline for a tired parent. Whether it is your morning ritual or a way to wind down at night, tea is often a staple in many households. However, as a breastfeeding mom, you probably find yourself questioning every ingredient that passes your lips. You might wonder if that cup of Earl Grey is causing your baby to stay awake longer or if a peppermint blend is the reason your pump output seems lower today.
At Milky Mama, we know that these small details can feel overwhelming when you are focused on nourishing your little one. We understand that you want to do what is best for your body and your baby while still enjoying the small comforts of life. Understanding how different types of tea interact with your body is essential for maintaining a healthy milk supply. If you want a supportive sip alongside your tea routine, try our Lactation LeMOOnade™.
This post covers which teas can support your lactation journey, which ones you might want to avoid, and how caffeine plays a role in your baby’s behavior. We will also explore how hydration and specific herbs can impact your overall milk production. Every body is unique, but having the right information helps you make empowered choices for your breastfeeding goals.
Understanding Tea and Breastfeeding
Tea is one of the most popular beverages in the world. It comes in many forms, from traditional caffeinated leaves like black and green tea to a vast array of herbal infusions. When you are breastfeeding, the components of these teas can enter your bloodstream and, in small amounts, your breast milk.
The primary concerns for breastfeeding parents usually fall into two categories. First is the effect of stimulants like caffeine on the infant. Second is the effect of specific herbs on the volume of milk produced. Some herbs are known as galactagogues. A galactagogue is a substance that may help increase breast milk production. On the other hand, some herbs are considered anti-galactagogues, which means they might decrease your supply.
It is important to remember that breastfeeding is a system of supply and demand. While tea can play a supportive role, the most effective way to maintain supply is through frequent milk removal. However, choosing the right tea can certainly complement your efforts and provide a much-needed moment of relaxation.
Caffeine and Your Milk Supply
One of the most frequent questions we hear is whether the caffeine in tea affects milk supply. Most varieties of "true" tea, such as black, green, white, and oolong, come from the Camellia sinensis plant. This plant naturally contains caffeine.
Does Caffeine Pass Through Breast Milk?
A small percentage of the caffeine you consume does end up in your breast milk. For most healthy, full-term infants, a moderate amount of caffeine is perfectly safe. Most experts suggest that up to 300 milligrams of caffeine per day is acceptable for breastfeeding parents. For context, an average cup of black tea contains about 40 to 70 milligrams.
However, newborns and premature babies process caffeine much more slowly than adults or older infants. If you notice your baby is unusually fussy, jittery, or having trouble sleeping, it may be worth looking at your caffeine intake. A baby who is overly stimulated might not nurse as effectively, which could indirectly affect how much milk your body produces.
Does Caffeine Dehydrate You?
There is a common myth that caffeine is a significant diuretic that will dehydrate you and tank your supply. While caffeine has a mild diuretic effect, meaning it may make you urinate more, the water in the tea usually compensates for this. As long as you are drinking plenty of water throughout the day, a few cups of tea are unlikely to cause dehydration.
Key Takeaway: Moderate caffeine intake from tea is generally safe for breastfeeding. If your baby seems extra sensitive or restless, try reducing your intake or timing your tea for after a nursing session.
Herbs That May Increase Milk Supply
Many cultures have used herbal teas for centuries to support nursing mothers. These herbal blends are often marketed as "Nursing Tea" or "Mother's Milk" tea. They typically contain a mix of herbs believed to support the hormones responsible for lactation.
Blessed Thistle
Blessed Thistle is a common ingredient in lactation teas. It is thought to support the flow of milk and is often used in combination with other herbs. Many moms find that it helps support their let-down reflex. The let-down reflex is the physiological response that causes milk to be released from the milk ducts.
Nettle Leaf
Stinging Nettle is a powerhouse of nutrition. It is rich in iron, calcium, and vitamin K. Because it is so nutrient-dense, it helps support the mother's overall wellness. A well-nourished body is often better equipped to produce a healthy milk supply. Many lactation consultants recommend nettle as a gentle way to boost mineral intake.
Moringa
Moringa is an herb that has gained a lot of attention in the lactation world. It is highly concentrated in vitamins and minerals. Some studies suggest that moringa can significantly support milk production by supporting the production of prolactin. Prolactin is the primary hormone responsible for telling your body to make milk. We include high-quality herbs in our products like Pumping Queen™ to help provide this kind of targeted support.
Red Raspberry Leaf
While often associated with the late stages of pregnancy, red raspberry leaf is also beneficial during the postpartum period. It is known as a uterine tonic, helping the uterus return to its pre-pregnancy size. It is also rich in vitamins and may help support a steady milk supply for some parents.
Action Steps for Using Herbal Teas:
- Start with one cup a day to see how you and your baby react.
- Check the ingredient list for any fillers or artificial sweeteners.
- Consult with a certified lactation consultant to find the best blend for your needs.
- Keep a log of your supply if you are trying to measure the impact of a specific herb.
Teas That May Decrease Milk Supply
Just as some herbs can help, others are known to do the opposite. These are often used by parents who are overproducing or those who are ready to begin the weaning process. If you are trying to maintain or increase your supply, you should be cautious with these ingredients.
The Impact of Sage
Sage is perhaps the most well-known herb for reducing milk supply. It contains compounds that can decrease the production of breast milk. It is often recommended in high doses for moms who are dealing with a painful oversupply or for those who want to stop breastfeeding entirely. Even culinary amounts of sage in a tea blend could potentially impact a sensitive supply.
Peppermint and Spearmint
Peppermint is a tricky one. Many people love peppermint tea for digestion or headaches. While a single peppermint candy is unlikely to cause issues, drinking several cups of strong peppermint tea daily may decrease milk production for some women. This is thought to be due to the menthol content. If you notice a dip in your supply, it might be time to swap your peppermint tea for something else.
Parsley
While usually eaten as a garnish, parsley can also be brewed into a tea. In high concentrations, parsley is considered an anti-galactagogue. If you are enjoying a Mediterranean-style tea blend or a green detox tea, check to see if parsley is a main ingredient.
The Role of Hydration in Lactation
One of the reasons tea can be beneficial is simply because it encourages you to drink more fluids. Breast milk is about 88% water. If you are dehydrated, your body may struggle to maintain an optimal volume of milk.
However, drinking excessive amounts of water beyond your thirst levels will not necessarily produce more milk. The goal is to stay comfortably hydrated. Tea can be a flavorful way to reach your hydration goals, especially if you find plain water boring.
If you are looking for hydration that goes a step further, our Pumpin Punch™ or Lactation LeMOOnade™ are excellent options. They are designed to provide hydration while including ingredients that support lactation. They offer a refreshing alternative to hot tea, especially during the warmer months.
Safety and Ingredient Considerations
Not all herbal teas are created equal. Since the FDA does not regulate herbal supplements in the same way it regulates medications, the quality and purity of tea can vary.
Ingredients to Avoid
When choosing a tea, be wary of "detox" or "weight loss" teas. These often contain senna or other laxatives that can be harsh on your system and potentially cause diarrhea in your nursing baby. You should also avoid herbs like comfrey, coltsfoot, and borage, as these can contain alkaloids that are not safe for infants.
Hibiscus is another ingredient to be cautious with. While it is common in many fruity herbal teas, some studies suggest it may interfere with milk production if consumed in very large quantities. As with most things, moderation is usually the safest path.
Consult the Professionals
Before starting any new herbal regimen, it is a great idea to speak with your healthcare provider or visit our Certified Lactation Consultant Breastfeeding Help.
Key Takeaway: This product is not intended to diagnose, treat, cure, or prevent any disease. Consult with your healthcare provider for medical advice.
Maximizing the Benefits of Tea Time
Tea can be more than just a drink; it can be a part of your self-care routine. High stress levels can inhibit the let-down reflex. When you are stressed, your body produces cortisol, which can interfere with oxytocin. Oxytocin is the "love hormone" that helps your milk flow.
Taking ten minutes to sit quietly with a cup of tea can lower your stress levels. This relaxation can actually help your milk flow more freely during your next nursing or pumping session. Consider choosing caffeine-free options like chamomile or lavender in the evening to help you and your baby stay calm.

- Listen to your body: Drink when you are thirsty and eat when you are hungry.

- Get support: If you are struggling with a latch or supply concerns, don't hesitate to explore our Breastfeeding 101 course.
Conclusion
The question of whether tea affects breast milk supply does not have a simple "yes" or "no" answer. It depends entirely on what is in your cup. Some teas, like those containing moringa or blessed thistle, can be wonderful allies in supporting your lactation. Others, like sage or excessive peppermint, might cause your supply to dip.
Caffeine is generally safe in moderation, but it is always wise to keep an eye on your baby's temperament. Most importantly, use your tea time as a moment to breathe and appreciate the incredible work your body is doing. Your well-being matters just as much as your milk supply.
- Choose herbal blends designed for lactation.
- Limit caffeine to 300mg per day.
- Avoid sage and high amounts of peppermint.
- Stay hydrated with a variety of fluids.
Final Thought: Your breastfeeding journey is unique to you. Whether you choose tea, lactation treats, or herbal supplements, the best approach is one that makes you feel supported and empowered.

FAQ
Can I drink green tea while breastfeeding?
Yes, you can drink green tea while breastfeeding, but it is best to do so in moderation due to the caffeine content. Green tea generally has less caffeine than black tea or coffee, making it a popular choice for nursing moms. Just keep an eye on your baby for any signs of caffeine sensitivity, such as extra fussiness or trouble napping. For a closer look at hydration and supply, read our Does Drinking Water Help Breast Milk Supply?.
Will drinking peppermint tea dry up my milk?
While a single cup of peppermint tea is unlikely to have a major impact, drinking it in large quantities may decrease milk supply for some people. Peppermint contains menthol, which some believe can act as an anti-galactagogue. If you are concerned about your supply, you might want to choose a different herbal tea, like ginger or chamomile, and check our What Helps Breast Milk Supply: Practical Tips and Support.
What is the best tea for increasing milk supply?
Teas containing galactagogues like blessed thistle, nettle leaf, and moringa are often considered the most helpful for boosting supply. These herbs are traditionally used to support the hormones and nutrients needed for lactation. It is always a good idea to check the full ingredient list to ensure there are no herbs you are sensitive to.
Does chamomile tea affect breast milk?
Chamomile tea is generally considered safe for breastfeeding and can actually be quite beneficial. It is caffeine-free and known for its calming properties, which can help reduce stress for the mother. Lower stress levels can support a better let-down reflex, making it easier for milk to flow during feedings.
