Introduction

Finding yourself worried about your milk supply is a common experience for many parents. You might spend hours scrolling through forums or asking friends for advice on how to ensure your baby is getting enough. One of the most frequent suggestions you will likely hear is to try a lactation tea. These herbal blends have been used for generations, but you may wonder if they actually deliver on their promises or if they could potentially backfire.

At Milky Mama, we believe that every drop counts and that you deserve support rooted in clinical expertise. Founded by Krystal Duhaney, a Registered Nurse and International Board Certified Lactation Consultant (IBCLC), our mission is to provide you with the tools and knowledge to navigate your breastfeeding journey with confidence. Whether you are struggling with a temporary dip in supply or just want a little extra boost, understanding how these teas work is a great first step.

In this article, we will explore whether lactation teas can actually lower your supply and examine the evidence behind common herbal ingredients. We will also discuss the physiological side of milk production to help you see the full picture. While herbal support can be helpful, it is most effective when you understand how your body makes milk.

Understanding Lactation Tea and Galactagogues

Lactation tea is an herbal infusion designed to support and increase breast milk production. These teas typically contain a blend of specific herbs known as galactagogues. A galactagogue is simply a substance that may help a person's body produce more milk. The word comes from the Greek "galakta," meaning milk, and "agogue," meaning to lead or bring forth.

For centuries, families across different cultures have used plants and seeds to support nursing. These traditions have been passed down through generations of parents and midwives. Today, these ancient remedies are conveniently packaged into tea bags found in most grocery stores. Most "mother's milk" teas use a combination of several herbs to target different aspects of lactation and digestion.

It is important to remember that these teas are considered herbal supplements. This means they are used to support your body's natural functions rather than "curing" a medical issue. When you sip a cup of warm tea, you are not just getting the herbal benefits. You are also taking a moment to hydrate and relax, both of which are vital for a healthy milk supply.

Can Mothers Milk Tea Lower Milk Supply?

The short answer for most people is no. For the vast majority of breastfeeding parents, lactation teas are intended to increase supply, not decrease it. However, because every body is unique, there are a few nuanced reasons why some people feel like their supply has dropped after starting a tea.

Individual Sensitivities and Paradoxical Reactions

In rare cases, a person may have a paradoxical reaction to an herb. This means that instead of the herb performing its intended function (increasing supply), it causes the opposite effect or creates stress in the body that hinders the let-down reflex. The let-down reflex is the process where your milk begins to flow from the small sacs in your breast into the ducts. If you are sensitive to an ingredient, your body may react with physical stress or digestive upset, which can temporarily impact how well your milk flows.

Digestive Issues and Stress

Some herbs found in lactation blends are very potent. If an herb causes you to have an upset stomach, gas, or diarrhea, your body is under physical stress. Stress is a well-known inhibitor of oxytocin. Oxytocin is the "feel-good" hormone responsible for pushing milk out of the breast. If you aren't feeling well because of the tea, you may find it harder to get a good let-down, making it appear as though your supply has lowered.

Replacing Nutrition with Tea

Sometimes, parents get so focused on "magic" remedies that they forget the basics. If you are drinking several cups of tea a day but forgetting to eat enough calories or protein, your supply may suffer. Tea is mostly water. While hydration is key, your body needs actual energy to produce milk. If the tea is making you feel full and causing you to skip meals, that could lead to a dip in production.

The Misunderstanding of "Fullness"

As your breastfeeding journey progresses, your breasts may stop feeling "full" or "engorged." This is a normal sign of your supply regulating to meet your baby's needs. If this happens right when you start a lactation tea, you might mistakenly blame the tea for a "loss" of milk. In reality, your body is just becoming more efficient.

Key Takeaway: While lactation tea is designed to boost supply, physical stress from sensitivities or neglecting overall nutrition can lead to a perceived or temporary dip.

Common Ingredients in Lactation Blends

Most brands of lactation tea use a similar profile of ingredients. Understanding what is in your cup can help you decide which blend is right for you. You can also review Milky Mama's ingredient guide for lactation-supportive foods and herbs.

Fennel Seed

Fennel is one of the most well-known galactagogues. It has a distinct licorice-like flavor and has been used for centuries to support nursing. Fennel contains compounds that may help stimulate mammary growth and milk production. Beyond lactation, fennel is excellent for digestion and may help reduce gas in both you and your baby.

Blessed Thistle

Blessed thistle is often used in combination with other herbs. It is believed to increase the flow of blood to the mammary glands. This provides the necessary nutrients for milk synthesis. It is also known as a "bitter" herb, which can support liver health and digestion.

Milk Thistle

Milk thistle is frequently included in lactation blends due to its potential to support prolactin levels. Prolactin is the primary hormone responsible for "telling" your body to produce milk. It is also highly regarded for its ability to support and protect the liver.

Moringa (Malunggay)

Moringa is a nutrient-dense leaf that has gained massive popularity. It is packed with vitamins and minerals, making it a great overall supplement for postpartum wellness. Many of our products at Milky Mama, such as our Pumping Queen™ capsules, utilize high-quality herbs like moringa to support parents without the use of ingredients that some find problematic.

Anise and Coriander

These seeds are often added to lactation teas to enhance the flavor and provide additional digestive support. Like fennel, anise has properties that can support the hormonal side of milk production. Coriander is often included to help balance the blend and provide a soothing effect on the digestive tract.

Herbs That Can Actually Lower Supply

If you are concerned about your supply dropping, it is more likely that you have encountered "anti-galactagogues." These are herbs traditionally used to help dry up milk supply during weaning. If these are in your kitchen or your tea, they could be the culprit.

Sage: This is the most potent herb for reducing supply. It is often used by parents who are overproducing or those who are ready to stop breastfeeding.
Peppermint: In very large amounts, peppermint (especially peppermint oil) can have a drying effect on milk supply. A single peppermint candy is usually fine, but several cups of strong peppermint tea might cause an issue for some.
Parsley: Like sage, large amounts of parsley are traditionally used to help slow down milk production.
Jasmine: Some traditions suggest that even the scent of jasmine or applying jasmine flowers to the breasts can reduce milk supply.

If your "mother's milk" tea consists of these ingredients, it isn't actually a lactation tea. Always check the label to ensure you aren't accidentally consuming herbs meant for weaning.

The Science: Does Lactation Tea Really Work?

When looking at whether these teas actually work, the answer is often a mix of clinical data and anecdotal evidence. Many parents report a noticeable increase in their milk volume within a few days of starting a regular tea regimen. Some studies have shown that infants whose mothers used certain herbal teas regained their birth weight faster.

However, scientific research on herbal supplements can be limited. While many small trials show positive results, larger clinical studies are still needed to provide a definitive answer. Most lactation consultants agree that while the herbs themselves may provide a hormonal boost, other factors are also at play.

For instance, the act of drinking tea increases your daily fluid intake. Hydration is a cornerstone of milk production. If you are dehydrated, your body may struggle to maintain its supply. Additionally, the ritual of sitting down with a warm beverage can lower your stress levels. When you relax, your body more easily releases oxytocin.

The Golden Rule: Supply and Demand

While tea can be a wonderful supplement, it is secondary to the most important factor in milk production: the removal of milk. Breastfeeding operates on a supply-and-demand system. The more milk is removed from your breasts, the more your body will create to replace it. Milky Mama's guide on how to increase milk supply covers additional strategies for pairing supplements with effective feeding techniques.

If you are only drinking tea but not nursing or pumping frequently, your supply is unlikely to increase significantly. Your body needs the physical signal that milk is needed. This is why we often recommend power pumping or adding extra nursing sessions alongside herbal support.

When you remove milk, your body lowers the level of a protein called Feedback Inhibitor of Lactation (FIL). When FIL levels are low, your milk-making cells work faster. If the breast remains full, FIL builds up and tells your body to slow down production. Therefore, any tea or supplement works as a helper to the physical work your body is already doing.

Action Steps for Increasing Demand:

Ensure your baby has a deep, effective latch.
Nurse or pump every 2 to 3 hours.
Try breast massage or compressions while feeding.
Check your pump parts for wear and tear to ensure efficient milk removal.

Why Your Supply Might Be Dropping (That Isn’t the Tea)

If you have noticed a dip in supply while taking a lactation tea, it is worth looking at other common factors that might be the true cause.

Hormonal Changes

The return of your menstrual cycle can cause a temporary dip in milk supply. This is usually due to a drop in blood calcium levels around the time of ovulation or right before your period starts. Many parents find that their supply returns to normal once their period begins.

Illness or Dehydration

If you have a cold, the flu, or a stomach bug, your body is redirecting energy toward healing. This can cause a temporary decrease in milk production. Additionally, some over-the-counter cold medications contain decongestants that are specifically designed to dry up fluids, which can include your milk.

Stress and Lack of Sleep

It is a tall order to ask a new parent to "just relax" and "sleep more." However, extreme fatigue and chronic stress can elevate cortisol levels. Cortisol can interfere with the hormones needed for milk production. Finding even small pockets of rest can make a difference.

Pregnancy

If you have a sudden, unexplained drop in supply, it may be worth taking a pregnancy test. Pregnancy causes a significant shift in hormones that often leads to a decrease in milk volume, regardless of how many galactagogues you consume.

How to Get the Most Out of Your Lactation Support

If you decide to continue using herbal support, how you use it matters. Consistency and quality are the two most important factors.

Follow the Instructions

Most herbal teas require a longer steep time than traditional black or green tea. To extract the beneficial properties from seeds like fennel, you may need to let the bag sit in hot water for 10 to 15 minutes. Covering your mug while it steeps helps keep the essential oils from escaping.

Be Consistent

Drinking one cup of tea once a week is unlikely to yield results. Most manufacturers recommend drinking 1 to 3 cups per day to maintain a steady level of the herbs in your system. This allows the compounds to build up and work effectively with your hormones.

Choose High-Quality Sources

Not all supplements are created equal. At Milky Mama, we pride ourselves on using high-quality, effective ingredients. Our Emergency Brownies® and Lady Leche™ supplements are formulated to provide targeted support. We focus on ingredients that have been used successfully by thousands of parents in our community.

Listen to Your Baby

The best way to tell if your supply is adequate is to look at your baby, not your pump parts. If your baby is having at least 6 heavy wet diapers in 24 hours, gaining weight appropriately, and seems satisfied after most feeds, your supply is likely right where it needs to be. Milky Mama's breastfeeding resource center includes guidance on feeding signs, diaper counts, and milk supply.

Moving Beyond Tea: A Holistic Approach

If you find that tea isn't for you, or if you are worried it's affecting you negatively, don't worry. There are many other ways to support your lactation journey.

Skin-to-Skin Contact: Spending time skin-to-skin with your baby boosts oxytocin and encourages frequent nursing.
Nutritious Snacks: Instead of just liquids, try lactation-supportive foods. Our lactation cookies and brownies provide the oats and flaxseed your body loves, along with the calories you need.
Professional Support: Sometimes the issue isn't what you're eating, but a physical hurdle like a tongue tie or a poor latch. Consulting with an IBCLC can provide personalized solutions that no tea can offer.

Conclusion

The idea that a standard mother's milk tea will lower your supply is largely a myth. However, the way your body reacts to specific herbs, your stress levels, and your overall nutrition play a massive role in your breastfeeding success. If you feel that a certain tea isn't working for you, it is perfectly okay to stop and try a different approach.

Remember these key points:

Standard lactation herbs are intended to boost, not lower, supply.
Avoid weaning herbs like sage and large amounts of peppermint.
Milk removal (demand) is the most important factor in milk production.
Your well-being and stress levels directly affect your let-down reflex.

You are doing an amazing job, and every drop you provide is a gift to your baby. If you need more support, we are here for you with our range of products and our supportive community. Whether you choose a tea, a supplement, or a tasty treat, make sure it makes you feel empowered and supported in your journey.

FAQ

Can drinking too much lactation tea lower my supply?

Drinking excessive amounts of tea is unlikely to lower your supply directly, but it could cause digestive upset or lead you to skip necessary meals. If the tea causes you physical stress or replaces vital calories and nutrients, you might see a temporary dip in production. It is usually best to stick to the recommended 1 to 3 cups per day.

Why does my supply seem lower after starting mother's milk tea?

If you see a dip, it could be a paradoxical reaction to an herb, an underlying sensitivity, or a coincidence. Other factors like the return of your period, a new pregnancy, or increased stress are often the true culprits. Additionally, if the tea makes you feel unwell, the physical stress can inhibit your let-down reflex.

Are there any herbs I should avoid while breastfeeding?

Yes, certain herbs known as "anti-galactagogues" can lower milk supply. Sage is the most common herb used to dry up milk, followed by large amounts of peppermint and parsley. Always check your herbal blends and seasonings to ensure they do not contain high concentrations of these if you are trying to maintain or increase your supply.
