Introduction

If you have ever spent a late night scrolling through breastfeeding forums, you have likely seen one specific herb recommended more than any other. It is the most common ingredient found in lactation supplements across the United States. Many parents try it with high hopes, but the results can be surprisingly mixed. At Milky Mama, we understand how stressful it is to worry about your production. You want to provide for your little one, and the pressure to find a quick fix is real.

We believe that every drop counts and that you deserve support that is rooted in clinical expertise. While this popular Mediterranean spice is often hailed as a miracle worker, many families find that it doesn't live up to the hype. In some cases, it may even have the opposite of the intended effect. This post explores how certain herbal supplements interact with your body and whether they are truly the best choice for your lactation journey. We will look at why some parents see a boost, while others experience a frustrating dip in their supply.

Understanding the Role of Galactagogues

Before we look at the specific herb in question, it is helpful to understand what a galactagogue is. A galactagogue is any food, herb, or medication that may help increase a mother’s milk supply. The word comes from the Greek "galakta," meaning milk. People have used various plants for centuries to support breastfeeding. However, it is important to remember that these are not "magic pills."

Breastfeeding is primarily a system of supply and demand. Your body makes milk based on how much is removed. When a baby or a pump removes milk from the breast, your body gets the signal to make more. Galactagogues are meant to support this natural process, not replace it. If the fundamental mechanics of milk removal are not in place, no herb can fully fix a supply issue.

Key Takeaway: Galactagogues are supplements intended to support milk production, but they work best when paired with frequent and effective milk removal.

How the Most Common Lactation Herb Affects the Body

The herb we are discussing is a member of the legume family. It has been used for thousands of years in cooking and traditional medicine. In the context of lactation, the theory behind its use is quite unique. Scientists believe that this plant stimulates sweat production.

Because the mammary glands are actually modified sweat glands, the herb may trigger increased activity in the breast tissue. This is why many people believe it is an effective way to boost output. For some parents, this stimulation works well. They might notice their breasts feel fuller within 24 to 72 hours of starting the supplement.

However, this stimulation comes with a very distinct calling card. The herb contains a compound called sotolon. This compound passes through your system and can make your sweat, urine, and even your baby’s diapers smell exactly like maple syrup. While this might sound pleasant to some, it is a sign of how strongly the herb affects your body’s secretions.

Does It Increase or Decrease Milk Supply?

The answer to whether this supplement increases or decreases supply is not the same for everyone. For many people, it does provide a noticeable boost in volume. Studies have shown that some parents see an increase in milk production when using it under the right conditions.

However, there is a significant group of people who find that it actually decreases their milk supply. This is often a shock to parents who were told it was the gold standard for lactation support. There are several reasons why this negative reaction might occur.

The Impact on Thyroid Health

Your thyroid plays a massive role in your ability to produce milk. Thyroid hormones regulate your metabolism and the production of prolactin, which is the "milk-making" hormone. This specific herb has been linked to changes in thyroid function in some individuals. If your thyroid levels are already low (hypothyroidism) or if you have a pre-existing thyroid condition, this supplement might interfere with your hormone balance. When your thyroid is suppressed, your milk production can drop significantly.

Insulin and Blood Sugar Regulation

This herb is also known for its ability to lower blood sugar. While this can be beneficial for some health conditions, it can be problematic for breastfeeding. Stable blood sugar is essential for maintaining a steady energy supply for milk production. If your blood sugar drops too low, your body may prioritize its own survival over milk production.

Furthermore, parents with Polycystic Ovary Syndrome (PCOS) often struggle with insulin resistance. Many lactation consultants have observed that parents with PCOS often experience a decrease in supply when taking this specific herb. Because PCOS already involves a complex hormonal balance, adding a supplement that affects insulin can disrupt the system further.

Potential Side Effects for Mom and Baby

Even if the supplement does help your supply, it is important to consider the potential side effects. Because this herb is a legume, it can cause significant digestive distress.

For Mom: Many people report feeling very gassy or bloated. It can also cause loose stools or diarrhea.
For Baby: The compounds that cause gas in the parent can pass through the milk. This often leads to a fussy, "colicky" baby who has stomach pains or green, watery stools.
Allergy Risks: Since this plant is related to peanuts and chickpeas, people with those allergies should avoid it entirely to prevent a dangerous reaction.

If you notice that you or your baby are experiencing significant digestive upset, it may be time to reconsider your supplement choice. Every body is different, and what works for your friend might not be the right fit for your unique biology.

Why Milky Mama Chooses a Different Path

When our founder, Krystal Duhaney, RN, BSN, IBCLC, began formulating our products, she looked closely at the clinical data. She saw that while the most common lactation herb is popular, it is also the source of the most complaints from breastfeeding parents.

At Milky Mama, we decided to be a fenugreek-free lactation brand. We wanted to create products that support supply without the risk of maple syrup odors, digestive issues, or hormonal crashes for those with PCOS or thyroid issues. We believe that breastfeeding support should feel compassionate and empowering, not like a gamble with your health.

Our products are designed to be both delicious and effective. We use alternative ingredients that have a long history of safe use and strong anecdotal and clinical support. We want you to feel confident that what you are putting into your body is helping you reach your goals.

Evidence-Based Alternatives for Milk Supply

If you are looking to boost your supply without the risks associated with traditional Mediterranean herbs, there are many other wonderful options. Here are some of the ingredients we love and why they work.

Blessed Thistle

Blessed Thistle is a plant that has been used since the Middle Ages. It is often paired with other herbs to support milk production. Unlike the more common legumes, Blessed Thistle is generally better tolerated by the digestive system. It is believed to work by increasing the flow of blood to the mammary glands and supporting the release of hormones like oxytocin.

Goat’s Rue

Goat's Rue is a powerhouse for lactation support, especially for parents who may have insufficient glandular tissue. It belongs to the same family as some other legumes, but it works differently. It is believed to stimulate the development of the mammary tissue itself, which can lead to a more sustainable increase in supply over time. If you want a deeper dive, our guide on Goat’s Rue and milk supply is a helpful place to start.

Black Seed (Nigella Sativa)

Black seed is another ancient remedy that is gaining popularity in the modern world. Some studies suggest it can significantly increase prolactin levels. Prolactin is the hormone responsible for telling your body to produce milk. By supporting healthy prolactin levels, black seed helps ensure your body is getting the right messages to keep up with your baby's needs.

Moringa

Moringa is a nutrient-dense plant often called a "superfood." It is incredibly high in iron, calcium, and vitamins. For many parents, a dip in supply is related to nutritional gaps or fatigue. Moringa helps nourish the mother's body, providing the building blocks needed for high-quality milk production.

What to do next:

Consult with an IBCLC if you are concerned about your supply.

Evaluate your current supplements for any that might be causing side effects.

Focus on frequent milk removal through nursing or pumping.

Consider trying a different lactation support option if this herb does not agree with your body.

The Importance of Milk Removal

No matter which supplement you choose, it will not work unless you are also removing milk from your breasts. This is the most critical part of the breastfeeding puzzle. Your breasts work on a "drain to gain" principle. The emptier the breast is, the faster it works to refill.

If you are struggling with supply, try adding an extra pumping session or spending more time doing skin-to-skin contact with your baby. Skin-to-skin contact triggers a surge of oxytocin, the "love hormone," which helps your milk let down. The let-down reflex is what allows the milk to flow out of the breast.

Many parents find success with "power pumping." This involves a specific schedule of pumping and resting to mimic a baby's cluster feeding. This tells your body that there is a sudden, high demand for milk, which can help jumpstart production within a few days. For a step-by-step routine, see our guide to power pumping for milk supply.

Nourishing Your Body for Successful Lactation

Maternal wellness is a huge part of the lactation journey. You cannot pour from an empty cup. If you are exhausted, dehydrated, or under-nourished, your body will have a harder time making milk.

Hydration and Electrolytes

You need a lot of water to make milk, but water alone isn't always enough. Your body needs electrolytes like magnesium, potassium, and calcium to stay truly hydrated. This is why we created our lactation drinks like Pumpin' Punch™ and our lactation drink mixes. They provide hydration plus lactation-support ingredients to help you feel your best.

High-Quality Nutrition

Eating foods rich in healthy fats and complex carbohydrates can give you the energy you need. Oats, flaxseed, and brewer's yeast are traditional favorites for a reason. They provide B vitamins and minerals that support overall wellness. Our Emergency Lactation Brownies are one of our most-loved lactation treats, and you can find more options in our lactation brownies collection.

"Breasts were literally created to feed human babies."

You are doing an incredible job navigating these challenges. It is completely normal for breastfeeding to feel difficult at times. It is a natural process, but it doesn't always come naturally. Whether you are exclusively breastfeeding, pumping, or a mix of both, your well-being matters just as much as your milk supply.

When to See a Professional

If you have tried changing your routine and your supply is still not where you want it to be, please reach out for professional help. A Certified Lactation Consultant (IBCLC) can help you identify the root cause of your supply issues. They can check your baby’s latch, evaluate your pumping equipment, and look at your medical history to see if there are underlying factors like hormonal imbalances at play.

At Milky Mama, we offer virtual breastfeeding help to make professional support accessible from the comfort of your home. You don't have to figure this out alone. Having an expert in your corner can provide the peace of mind you need to move forward with confidence.

Conclusion

The question of whether a specific herb increases or decreases milk supply doesn't have a one-size-fits-all answer. For some, it is a helpful tool, but for many others—especially those with thyroid issues or PCOS—it can be a source of frustration and decreased production. By understanding how these supplements interact with your body and choosing science-backed alternatives, you can support your lactation journey more safely and effectively.

FAQ

Does every lactation supplement contain this specific herb?

No, many modern lactation brands, including Milky Mama, choose to offer options without it. We use alternative ingredients like Blessed Thistle, Goat’s Rue, and Black Seed to support milk production without the common side effects. This is especially helpful for parents with allergies or hormonal imbalances.

Why does my baby have gas when I take a new herbal supplement?

Many traditional lactation herbs are legumes, which contain complex sugars that can be difficult to digest. These compounds can pass into your breast milk and cause gas or bloating for your baby. If your baby becomes fussy or develops green stools, it may be a sign that the supplement is not agreeing with their digestive system.

Can a supplement actually make my milk supply go down?

Yes, it is possible for certain herbs to decrease supply in some individuals, particularly those with PCOS or thyroid disorders. These herbs can interfere with blood sugar levels or thyroid hormone production, both of which are critical for maintaining a healthy milk supply. If you notice a dip after starting a new supplement, it is best to stop and consult a lactation professional.
