Introduction
Expecting a baby is a time filled with excitement, anticipation, and a long list of things to do. If you are planning to breastfeed, you might be looking for ways to get a head start. It is natural to want to ensure your milk supply is ready the moment your little one arrives. You may have seen lactation cookies or herbal blends and wondered if taking them now could help you avoid supply issues later.
At Milky Mama, we believe that education is the best way to prepare for your feeding journey. While you want to do everything possible to set yourself up for success, the timing of when you start certain supports matters. This article will explore whether it is safe or necessary to take lactation supplements during pregnancy, how your body prepares for milk production, and what you can do now to support your future supply.
While the desire to prepare is wonderful, taking supplements before your baby is born is generally not recommended for several important reasons.
Understanding Lactation Supplements
Lactation supplements are products designed to support a person's milk supply. They often contain specific herbs or foods known as galactagogues. A galactagogue is simply a substance that may help increase milk production in humans. These supplements come in many forms, including capsules, teas, powders, and even baked treats. You can explore Milky Mama’s lactation supplement collection to see the types of products available for the postpartum period.
Common ingredients you might find in these products include:
- Blessed Thistle: An herb often used to support milk flow.
- Moringa: A nutrient-dense leaf that provides vitamins and minerals.
- Alfalfa: A plant rich in Vitamin K and antioxidants.
- Brewer’s Yeast: A type of yeast high in B vitamins and iron.
- Nettle: A leafy herb used for its high mineral content.
The goal of these ingredients is to support the hormones and nutritional needs required for lactation. However, these supplements are specifically formulated to work with a body that has already given birth.
How Galactagogues Work
Most galactagogues work by supporting the production of prolactin. Prolactin is the primary hormone responsible for telling your body to make milk. During pregnancy, your prolactin levels actually rise significantly. However, you do not produce large amounts of milk yet because another hormone, progesterone, keeps the "milk gates" closed.
Because your body is already under the influence of pregnancy hormones, adding herbal galactagogues often doesn't have the intended effect until after the baby is born.
Can You Take Lactation Supplements While Pregnant?
The short answer is that for most people, it is better to wait. While the idea of "pre-loading" your system sounds logical, it is usually not effective and can sometimes be risky. Most lactation consultants and healthcare providers suggest waiting until at least a few days after birth to introduce herbal supplements.
There are three main reasons why taking these supplements during pregnancy is generally discouraged:
- Hormonal Interference: Pregnancy is a delicate balance of hormones. Introducing herbs that affect prolactin or other hormones could potentially interfere with the natural progression of your pregnancy.
- Uterine Stimulation: Some herbs used in lactation blends can cause the uterus to contract. While this might be helpful during or after labor, it is something you want to avoid during pregnancy to prevent preterm labor.
- Lack of Necessity: Your body is already preparing for milk production on its own. Taking a supplement now won't necessarily result in more milk later because the actual "switch" for milk production hasn't been flipped.
Why Your Body Isn't Ready for Supplements Yet
During pregnancy, your breasts go through a process called Lactogenesis I. This is the first stage of milk production. During this time, your body begins creating colostrum. Colostrum is the "liquid gold" or first milk that is very thick, concentrated, and full of antibodies.
Even though you are making colostrum, you aren't making a high volume of milk because the placenta is still present. The placenta produces high levels of progesterone, which prevents the full onset of milk production. It isn't until the placenta is delivered that your progesterone levels drop, signaling your body to begin Lactogenesis II, which is when your milk "comes in." Supplements cannot override this biological timeline.
Key Takeaway: Your body has a natural clock for milk production that begins with the birth of your baby and the delivery of the placenta. Supplements are designed to support this process once it has already started.
Potential Risks to Consider
When you are pregnant, everything you consume can potentially affect your developing baby. Herbal supplements are not regulated by the FDA in the same way that medications are. This means we don't always have long-term studies on how every herb affects a pregnancy.
Uterine Contractions
Certain herbs like Blessed Thistle or even high doses of some teas could potentially stimulate the uterus. In a healthy pregnancy, you want the uterus to remain relaxed until it is time for labor. Taking these herbs too early could lead to Braxton Hicks contractions or, in rare cases, more serious concerns.
Blood Sugar and Blood Pressure
Some ingredients in lactation supplements can affect blood sugar levels or blood pressure. If you are managing gestational diabetes or pregnancy-induced hypertension, adding herbal supplements could complicate your treatment plan. Always speak with your OB-GYN or midwife before adding anything new to your routine.
Interactions with Prenatal Vitamins
You are likely already taking a prenatal vitamin. Adding a lactation supplement on top of that could lead to an excess of certain vitamins or minerals. While herbs are natural, "natural" does not always mean "safe for everyone at every time."
When is the Right Time to Start?
If you are worried about your supply, the best time to start thinking about supplements is after your baby is born. Most families find that they don't even need supplements in the first few days. For additional postpartum options, you can review Milky Mama’s lactation supplement collection.
Here is a general timeline for introducing support:
- Days 1–3: Focus on skin-to-skin contact and frequent feeding. Your baby’s stomach is the size of a marble, so the small amounts of colostrum you produce are perfect.
- Days 3–5: This is usually when your milk "comes in" and transitions from colostrum to mature milk.
- Week 1 and Beyond: If you feel your supply needs a boost or if you are returning to work and want to support your pumping output, this is the ideal time to introduce supplements.
Once you have reached the postpartum stage, you can explore options like our Lady Leche™ herbal supplement or Pumping Queen™. These are crafted to support you once your body has already entered the lactation phase.
Natural Ways to Prepare for Breastfeeding During Pregnancy
Just because you shouldn't take herbal supplements yet doesn't mean you can't prepare. There are many safe, healthy ways to support your body’s transition to breastfeeding while you are still pregnant.
Focus on Nutrition
Instead of herbal pills, focus on whole foods that naturally support your health. A well-nourished body is better equipped to handle the demands of making milk.
- Oats: Oats are a fantastic source of iron and fiber. Many people find that eating a bowl of oatmeal daily supports their supply later on.
- Flaxseed: Rich in healthy fats, flaxseed is great for brain health and general wellness.
- Leafy Greens: Spinach and kale provide calcium and iron, which are essential for both pregnancy and lactation.
- Healthy Fats: Avocado, nuts, and seeds provide the energy your body needs to grow a baby and eventually produce milk.
Our Emergency Brownies are a great example of how these ingredients come together. While they are a favorite for breastfeeding moms, many of the ingredients—like oats and flax—are simply healthy foods you can enjoy anytime.
Prioritize Hydration
Milk is mostly water. Staying hydrated during pregnancy helps maintain your amniotic fluid levels and supports your overall energy. Getting into the habit of drinking plenty of water now will make it easier to stay hydrated once you are breastfeeding.
If you find plain water boring, you can try hydration drinks that don't rely on heavy herbs. Milky Mama offers options like Pumpin Punch™ or Milky Melon™ which provide hydration and electrolytes. During pregnancy, always check the labels of any drink mix to ensure the ingredients align with your provider’s recommendations.
Practice Skin-to-Skin Preparation
You can't "practice" breastfeeding without a baby, but you can learn about the power of skin-to-skin contact. Research shows that holding your baby skin-to-skin immediately after birth and frequently in the early days is one of the best ways to jumpstart your milk supply. This contact triggers the release of oxytocin, which is the hormone responsible for the "let-down reflex" (the release of milk from the breast).
The Importance of Breastfeeding Education
The biggest factor in breastfeeding success isn't usually a supplement—it’s education. Understanding how breastfeeding works can lower your stress and help you navigate the early days with confidence. Milky Mama’s breastfeeding courses can help you prepare before your baby arrives.
Learn the "Supply and Demand" Rule
The most important thing to know is that milk production is a supply and demand system. The more milk that is removed from the breast (by the baby or a pump), the more milk your body will make. Supplements can support this process, but they cannot replace the need for frequent milk removal. You can learn more about this process in Milky Mama’s guide to increasing milk supply while pumping.
Recognize Feeding Cues
During pregnancy, you can learn what a hungry baby looks like. Instead of waiting for the baby to cry, look for:
- Rooting (turning the head and opening the mouth)
- Sucking on hands or fingers
- Smacking lips
Learning these cues now will help you respond quickly to your baby, which in turn helps establish your supply faster.
Take a Class
We highly recommend taking a breastfeeding class before your baby arrives. Many hospitals and private organizations offer virtual or in-person sessions. Learning about proper latch, different feeding positions, and how to tell if your baby is getting enough milk is the best "supplement" you can give yourself during pregnancy.
Action Plan for Expectant Moms
If you are feeling the urge to do something now to prepare for breastfeeding, follow this simple checklist:
- Consult your healthcare provider: Ask them about your interest in lactation support and see if they have specific recommendations for your health history.
- Eat "Galactagogue-Friendly" Foods: Incorporate oats, flax, and leafy greens into your daily meals. These are safe, nutritious, and healthy for pregnancy.
- Build Your Postpartum Kit: It is a great idea to buy your supplements now so they are ready when you get home from the hospital. Just keep them in the cupboard until your baby arrives.
- Find Support: Look for a local or virtual lactation consultant or a support group. Having a community makes a world of difference. Milky Mama offers breastfeeding help and virtual consultations for families who need individualized support.
- Hydrate: Buy a new water bottle you love and start hitting your daily hydration goals.
Next Steps: Focus on nourishing your body with whole foods and gathering your supplies for the postpartum period.
Creating a Stress-Free Postpartum Plan
Stress can actually inhibit the let-down reflex, making it harder for milk to flow. One of the best things you can do for your future milk supply is to reduce your stress during pregnancy.
- Set Realistic Expectations: Know that the first few weeks are a learning curve for both you and the baby.
- Prepare Your Recovery Station: Set up a comfortable spot with pillows, snacks, water, and your lactation supplies so you don't have to get up constantly.
- Communicate with Your Partner: Make sure they know how they can support you, whether it’s bringing you water, helping with diaper changes, or simply offering encouragement.
Remember, every drop counts. Whether you breastfeed for a week, a month, or a year, the effort you put into nourishing your baby is incredible. You are already doing an amazing job just by planning ahead and seeking out information.
Conclusion
While it is tempting to start lactation supplements while pregnant, your body is already doing the hard work of preparing for your baby on its own. The best approach is to focus on prenatal nutrition, stay hydrated, and educate yourself on the mechanics of breastfeeding. Save the herbal supplements for those first few weeks postpartum when your body is ready to put them to use.
- Wait until postpartum to start herbal lactation supplements.
- Focus on "milk-friendly" whole foods like oats and greens during pregnancy.
- Education and skin-to-skin contact are your best tools for early supply.

FAQ
Can I eat lactation cookies while pregnant?
Yes, most lactation cookies are safe to eat during pregnancy because they are primarily made of food-based ingredients like oats, flaxseed, and brewer’s yeast. These ingredients are nutritious and generally do not pose a risk, but you should always check the label for any specific herbs that your doctor may want you to avoid.
Will taking supplements early make my milk come in faster?
No, supplements will not typically make your milk come in faster. The transition from colostrum to mature milk is triggered by the hormonal shift that happens after the placenta is delivered. Frequent nursing and skin-to-skin contact are the most effective ways to encourage your milk to come in on time.
Are there any lactation herbs that are definitely unsafe during pregnancy?
Some herbs can cause uterine contractions or affect hormone levels, which is why most professionals recommend avoiding concentrated herbal lactation supplements until after birth. Since every pregnancy is unique, it is vital to consult your midwife or OB-GYN before taking any herbal products, as they can assess your specific health needs.
What should I do if I’m not leaking colostrum during pregnancy?
Not leaking colostrum during pregnancy is completely normal and is not an indicator of how much milk you will produce after birth. Many people never leak a drop while pregnant but go on to have a robust milk supply. Your body is still creating those early nutrients regardless of whether they leak out or not.
