Introduction

Preparing for a new baby is a whirlwind of nursery decorating, birth planning, and endless lists of must-have gear. It is completely natural to want to get a head start on your breastfeeding journey too. If you are an expectant parent, you might wonder if taking supplements now will help your milk come in faster or more abundantly later. At Milky Mama, we believe that education is the most powerful tool in your breastfeeding toolkit, and our Breastfeeding 101 course is a great place to start.

We know you want to do everything possible to set yourself up for success. However, when it comes to supplements designed to boost milk supply, timing is everything. This post will cover the science of how your body prepares for milk production, the safety of specific herbs during pregnancy, and the best ways to nourish your body before your baby arrives. Our goal is to help you feel confident and prepared for those first precious feeds.

The short answer is that most lactation supplements are not recommended during pregnancy, but there are many other ways to prepare.

Understanding Lactation Supplements

Lactation supplements are often referred to as galactagogues. A galactagogue is a substance—typically an herb, food, or medication—that is believed to help increase breast milk production. These products work in various ways. Some may support the hormones responsible for milk synthesis, while others provide specific nutrients that support overall maternal wellness.

Common ingredients in these supplements include herbs like blessed thistle, alfalfa, moringa, and milk thistle. You may also find nutritive ingredients like brewer’s yeast and flaxseed. While these are wonderful tools for many parents after the baby is born, they serve a specific purpose that does not align with the biology of pregnancy.

If you want to browse what is available for the postpartum phase, the lactation supplements collection is a helpful overview.

Your body is already doing the hard work of growing a human being. During pregnancy, your breasts are undergoing significant changes to prepare for feeding. However, the hormonal environment of pregnancy is very different from the hormonal environment of the "fourth trimester."

How Your Body Makes Milk During Pregnancy

To understand why you might not need supplements yet, it helps to know how milk production actually works. This process is called lactogenesis, and it happens in stages.

Lactogenesis I

This stage begins around the midpoint of your pregnancy. Your body starts to produce colostrum, which is the thick, nutrient-dense "liquid gold" that will be your baby's first food. Even if you do not notice any leaking, your breasts are likely already storing colostrum. If you want to learn more about this stage, this colostrum guide is a useful read. At this stage, your body is under the influence of high levels of progesterone. Progesterone is essential for maintaining a healthy pregnancy, but it also acts as a "brake" on your milk supply. It prevents your body from making large volumes of milk until the baby is actually here.

Lactogenesis II

This stage occurs after the birth of your baby and the delivery of the placenta. When the placenta leaves your body, your progesterone levels drop sharply. This drop signals your body to "release the brake" and start the transition from colostrum to mature milk. This usually happens between three to five days after birth.

Because progesterone is keeping your milk volume low during pregnancy, taking supplements to increase volume will likely not be effective. Your body is biologically programmed to wait for the birth before ramping up production.

Is It Safe to Take Lactation Herbs While Pregnant?

Safety is the primary reason why most lactation consultants and healthcare providers recommend waiting. Many herbs used in lactation supplements have not been extensively studied for use during pregnancy.

Uterine Stimulation

Some herbs that are helpful for milk flow may also cause uterine contractions. While mild contractions are normal later in pregnancy (like Braxton Hicks), you do not want to accidentally stimulate the uterus prematurely. Herbs like fennel or certain concentrated herbal blends can sometimes have this effect. It is always better to err on the side of caution to ensure your baby stays tucked away until they are full-term.

Hormonal Balance

Pregnancy is a delicate hormonal dance. Some galactagogues work by influencing hormones like prolactin. Introducing substances that alter your hormonal balance while you are still pregnant could potentially interfere with the natural progression of your pregnancy.

Interaction with Prenatals

You are likely already taking a prenatal vitamin. Adding herbal supplements on top of your daily vitamin can sometimes lead to an intake of certain nutrients that exceeds what is recommended. It can also make it harder for your healthcare provider to determine the cause of any side effects you might experience, such as digestive upset or skin rashes.

Key Takeaway: Most lactation supplements are designed for the postpartum hormonal environment and may carry risks, such as uterine stimulation, if taken during pregnancy.

When Should You Actually Start?

The best time to start thinking about lactation supplements is after your baby is born. For many parents, the first few days are all about skin-to-skin contact and frequent feeding to establish a natural supply. This "supply and demand" system is the most effective way to build your milk volume.

If you find that your milk is taking a little longer to transition after day five, or if you have concerns about your supply once you start pumping, that is the perfect time to reach out for support. We often suggest waiting until the "baby blues" period has passed and you have a clear picture of your feeding goals.

If you do decide to use supplements later, we recommend starting with one product at a time. This allows you to see how your body responds. Our Pumping Queen™ supplement, for example, is a popular choice for those looking to support their supply once they have returned to work or are building a freezer stash.

Exceptions to the Rule

There are very few situations where a person might take lactation-supporting substances while pregnant. One example is "tandem nursing." This is when a person continues to breastfeed an older child while they are pregnant with a new baby.

Even in these cases, it is vital to speak with an International Board Certified Lactation Consultant (IBCLC) and your obstetrician or midwife. They can help you determine if the supplements you are using are safe for the pregnancy while still supporting your nursing toddler. For the vast majority of first-time parents or those not currently nursing, waiting until birth is the standard recommendation. If you need one-on-one guidance, our Certified Lactation Consultant Breastfeeding Help page is a good place to begin.

Better Ways to Prepare During Pregnancy

Just because you shouldn't take supplements yet doesn't mean you can't be proactive. There are several evidence-based ways to prepare your body and mind for breastfeeding while you are still pregnant.

Focus on Prenatal Nutrition

Instead of lactation-specific herbs, focus on nutrient-dense foods that support fetal brain development and maternal health. One nutrient getting a lot of attention lately is choline. Choline is essential for the fetal nervous system and brain function. Most pregnant people in the U.S. do not get enough choline through diet alone. Foods like eggs, beef liver, chicken breast, and soy are excellent sources.

Stay Hydrated

Hydration is a cornerstone of milk production. Developing a habit of drinking plenty of water now will serve you well later. If you find plain water boring, you can try hydrating drinks that provide electrolytes. During the postpartum period, our lactation drink mixes collection is a fan favorite for staying hydrated while supporting lactation, but during pregnancy, simple fruit-infused water is a great choice.

Eat Galactagogue Foods

While concentrated herbal supplements are usually a "no" during pregnancy, many foods known for supporting supply are perfectly safe and healthy to eat now. These are often called "whole-food galactagogues."

Oats: Rich in iron and fiber, oats are a breastfeeding superstar. Enjoying oatmeal or oat-based snacks during pregnancy is a great way to nourish your body.
Flaxseeds: These provide healthy fats and fiber.
Leafy Greens: Spinach and kale provide calcium and iron, which you need plenty of during pregnancy.
Healthy Fats: Avocado, nuts, and seeds support your energy levels.

At Milky Mama, our Emergency Brownies are one of our most-loved treats for postpartum moms, but many of the ingredients—like oats and flax—are things you can incorporate into your daily meals right now in their natural form.

Educate Yourself

The biggest factor in breastfeeding success isn't a pill or a tea; it's knowledge. Take a breastfeeding class while you are pregnant. Learn about:

Proper latch techniques.
How to recognize feeding cues (rooting, sucking on hands).
Different nursing positions (cradle, football hold, side-lying).
The "supply and demand" principle.

Knowing what to expect during the first week can lower your stress levels, which in turn helps your milk flow more easily. The courses collection is a simple way to explore more learning options.

Create a Support System

Identify your "village" now. Find a local lactation consultant or a support group. Having these numbers saved in your phone before you are exhausted and overwhelmed will make a huge difference. We offer virtual lactation consultations that can be a lifesaver when you need professional, compassionate guidance from the comfort of your home.

Checklist for Breastfeeding Success

If you want to feel prepared without taking supplements, follow this simple action plan:

Consult your doctor: Always discuss any new vitamins or foods with your healthcare provider.
Eat for energy: Focus on whole grains, proteins, and healthy fats.
Stock your pantry: Buy the ingredients for healthy snacks so you have them ready for when the baby arrives.
Learn the signs: Understand the difference between a good latch and a painful one.
Rest: Your body is doing incredible work. Prioritize sleep whenever possible.

What to Look for in a Postpartum Supplement

Once your baby is here and you are ready to explore supplements, it is important to choose high-quality products. Look for brands that are transparent about their ingredients and rooted in clinical expertise. You want supplements that are free from fillers and focused on traditional, time-tested herbs.

Many parents find that a combination of hydration and herbal support works best. Whether you prefer a tasty drink mix, a herbal capsule, or a delicious lactation treat, the goal is to find what fits your lifestyle. If a capsule is more your style, the Pump Hero™ supplement is another postpartum option to explore. Remember, every body is different. What works for your best friend might not be the best fit for you, and that is okay.

The Role of Colostrum Harvesting

In the final weeks of pregnancy, some healthcare providers may suggest "colostrum harvesting." This involves hand-expressing small amounts of colostrum and storing it in tiny syringes to bring to the hospital. This is usually only recommended for those with specific medical conditions, such as gestational diabetes, or those who have had breast surgery.

Do not attempt this without specific instruction from your midwife or doctor, as nipple stimulation can sometimes trigger labor. However, learning the technique of hand expression is a very useful skill that you will definitely use after the baby is born. For more detail, this colostrum harvesting guide can help you understand the basics.

Final Thoughts on Pregnancy and Supplements

It is wonderful that you are already thinking about how to nourish your baby. That protective instinct is exactly what makes you a great parent. While it might be tempting to start those lactation supplements today, your body is currently on a different mission. Right now, your focus should be on prenatal health, hydration, and education.

Breastfeeding is a journey that evolves every day. Some days will feel easy, and other days might feel like a steep climb. We want you to know that you're doing an amazing job, even before the baby is here. When the time comes to transition into breastfeeding, we will be here with the products and support you need to thrive. If you want a deeper overview of how supply works, this guide to breast milk supply is a helpful next read.

Our Mission: We believe every parent deserves access to evidence-based support and nourishing products. Whether you are still pregnant or deep in the newborn haze, your well-being matters to us.

Next Steps for Expectant Moms

Keep taking your prenatal vitamins as directed by your doctor.
Incorporate oats and leafy greens into your weekly meal prep.
Sign up for a breastfeeding class to build your confidence.
Wait until your baby is at least a few days old before introducing herbal lactation supplements.

FAQ

Can I take lactation cookies while I am pregnant?

Yes, most lactation cookies are safe to eat during pregnancy because they are made from standard food ingredients like oats, flaxseed, and brewer's yeast. However, they are unlikely to increase your milk supply before birth due to the high progesterone levels in your body. They are simply a nutritious snack until your baby arrives and your hormones shift.

Will taking supplements now make my milk come in faster?

There is no scientific evidence that taking lactation supplements during pregnancy will make your milk "drop" or transition faster after birth. The transition from colostrum to mature milk is triggered by the delivery of the placenta and the subsequent drop in progesterone. Frequent nursing and skin-to-skin contact are the best ways to encourage this process postpartum.

What are the risks of taking herbal supplements before birth?

The primary risks include potential uterine stimulation, which could lead to premature contractions, and a lack of safety data regarding how these herbs affect fetal development. Some herbs can also interfere with other medications or prenatal vitamins. It is always best to wait until after delivery when your body is biologically ready for lactation support.

What should I do if I am worried about low milk supply before the baby is born?

It is very common to feel anxious about supply, but remember that your breasts were literally created to feed your baby. During pregnancy, focus on education and gathering resources. If you have a medical history that might affect supply, such as PCOS or previous breast surgery, schedule a prenatal consultation with an IBCLC to create a customized plan for when the baby arrives.
