Introduction

If you have ever spent a late night scrolling through breastfeeding forums, you have likely seen one specific herbal suggestion pop up again and again. It is often touted as the "go-to" for anyone worried about their output. However, many parents find themselves wondering if this popular, maple-scented herb actually delivers on its promises.

At Milky Mama, we know that worrying about your milk supply is one of the most stressful parts of the postpartum journey. Our founder, Krystal Duhaney, RN, BSN, IBCLC, created our products with a focus on evidence-based ingredients that support lactation safely. If you want a quick place to start, our lactation snacks collection is a helpful option for parents looking for support they can actually enjoy. In this post, we will take a deep dive into the research surrounding this common herbal supplement, explore its potential side effects, and discuss why we choose a different path for our lactation support.

Every drop counts, and you deserve to know exactly what you are putting into your body. While some people swear by traditional herbal remedies, the science behind them is often more complex than a social media post might suggest. We believe in empowering you with facts so you can make the best choice for your family.

What Is a Galactagogue?

Before we look at specific herbs, it is helpful to understand what a galactagogue actually is. A galactagogue is any substance—whether a food, herb, or medication—that is believed to help increase milk production. These substances usually work by interacting with the hormones responsible for making milk.

The two main hormones involved in breastfeeding are prolactin and oxytocin. Prolactin is the hormone that tells your body to make milk (lactogenesis). Oxytocin is the hormone that causes the "let-down reflex," which is the process of the milk moving through the ducts to the nipple.

Most herbal galactagogues are thought to work by mimicking estrogen or by increasing prolactin levels. However, it is important to remember that these substances are meant to be tools, not a replacement for the physical removal of milk. The primary way to maintain supply is through the "demand and supply" cycle. This means the more milk is removed from the breast, the more milk your body will make.

Key Takeaway: A galactagogue is a substance used to support milk production, but it works best when combined with frequent nursing or pumping.

The Science Behind This Traditional Herbal Supplement

When you look at the research regarding the most common maple-flavored herbal supplement, the results are quite mixed. Some studies suggest it can be helpful, while others show no significant difference compared to a placebo.

For example, a US survey of 122 mothers found that while 43% of them believed the herb helped increase their supply, 5% actually thought it caused their supply to decrease. This is a critical point because it shows that every body reacts differently to botanical ingredients. What works for one person may not work for another, and in some cases, it could even have the opposite of the intended effect.

One meta-analysis (a large study that reviews many other studies) found that this specific herb might have a mild effect on production. However, another meta-analysis found no strong evidence to support its use as a reliable galactagogue. Many of the studies that showed positive results used a mix of several different herbs, making it hard to tell which ingredient was actually doing the heavy lifting.

Potential Side Effects and Safety Concerns

One reason we are very careful with herbal recommendations is that "natural" does not always mean "risk-free." This particular herb, which is a member of the pea family, is known for several distinct side effects that can affect both the parent and the baby.

The Maple Syrup Odor

The most famous side effect is a strong odor of maple syrup in the parent's sweat, urine, and even the baby's diapers. This happens because of a compound called sotolon. While this might sound harmless, it can make it difficult for doctors to rule out certain metabolic disorders in newborns, which can lead to unnecessary medical testing.

Digestive Issues

Many parents report experiencing gas, bloating, nausea, or diarrhea when taking this supplement. Because the compounds in the herb pass through breast milk, some babies may also experience increased gas or tummy upset. If you notice your baby becoming fussier or having more frequent, loose stools after you start a new supplement, the herb could be the cause.

Blood Sugar and Thyroid Interactions

This herb can lower blood sugar levels (hypoglycemia). This is a major concern for parents with diabetes or those who are prone to low blood sugar. Furthermore, it can interfere with thyroid hormone levels. If you have a history of thyroid issues, it is essential to consult your healthcare provider before trying traditional lactation herbs.

Allergic Reactions

Since this herb is a legume, people with allergies to peanuts or chickpeas may also be allergic to it. Cross-reactivity is a real concern and can lead to symptoms ranging from mild hives to more severe respiratory issues, like the worsening of asthma symptoms.

What to Do Next:

Monitor your baby for signs of gas or digestive changes.

Check for the tell-tale maple syrup scent in your sweat or urine.

If you have a history of diabetes or thyroid issues, speak with a doctor.

Discontinue use if you notice a drop in your supply rather than an increase.

Why Milky Mama Chooses to Be Free From This Herb

At Milky Mama, we have made the conscious decision to keep our products free from this specific maple-scented herb. Our founder, Krystal Duhaney, made this choice based on her clinical experience as an IBCLC and a Registered Nurse.

We want to provide support that is as inclusive and safe as possible. By excluding ingredients that commonly cause digestive upset, interfere with thyroid function, or create confusion with metabolic screenings, we can support a wider range of breastfeeding families. We believe that you should not have to trade your digestive comfort or your baby’s temperament for a few extra ounces of milk.

Our focus is on utilizing other botanical ingredients that have a long history of traditional use with a different safety profile. We believe in providing nourishing support that feels good for both you and your little one.

Better Alternatives for Lactation Support

If you are looking for ways to boost your supply without the risks associated with the most common herbal supplements, there are many other options available. At Milky Mama, we use several key ingredients in our supplements and treats that many parents find more tolerable. You can also explore our lactation supplements collection to see the different ways parents support their routines.

Moringa

Moringa is often called a "superfood" for good reason. It is packed with vitamins, minerals, and proteins. Many studies suggest that Moringa can help support prolactin levels, making it a powerful choice for those looking to increase their output. You can find this ingredient in our Lady Leche supplement.

Alfalfa

Alfalfa is a nutrient-dense herb that is rich in Vitamin K, chlorophyll, and antioxidants. It has been used for generations to support milk production. Because it is so high in nutrients, it also helps support the parent's overall wellness during the demanding postpartum period. We include Alfalfa in our Dairy Duchess supplement.

Blessed Thistle

Not to be confused with Milk Thistle, Blessed Thistle is a traditional galactagogue often used to support the flow of breast milk. It is frequently paired with other herbs to create a comprehensive support system. Our Pumpin' Punch drink mix utilizes Blessed Thistle to help parents reach their pumping goals.

Goat's Rue

Goat's Rue is particularly unique because it is believed to help support the development of mammary tissue. This can be especially helpful for parents who have concerns about breast capacity or those who did not experience significant breast changes during pregnancy. You can find Goat's Rue in our Pumpin' Punch drink mix.

Biological Foundations of Milk Supply

While supplements can be a helpful tool, they work best when the biological foundations of breastfeeding are in place. Milk production is a demand-and-supply system. If the milk is not being removed effectively or frequently enough, your body will eventually slow down production.

Frequent Milk Removal

Your body needs frequent signals to keep making milk. For newborns, this usually means nursing 8 to 12 times in a 24-hour period. If you are pumping, consistent sessions are key. Even a short 10-minute session is better than skipping one entirely, as it tells your brain that the demand is still there.

Effective Latch and Drainage

It is not just about how often the baby is at the breast, but how well they are removing the milk. If the baby's latch is shallow, they may not be able to drain the breast effectively. Leftover milk contains a protein called Feedback Inhibitor of Lactation (FIL). When this protein builds up in the breast, it tells your body to stop making more milk. Ensuring a deep latch or using a high-quality pump helps remove this inhibitor.

Skin-to-Skin Contact

Never underestimate the power of a "nursing vacation." Spending time skin-to-skin with your baby releases a surge of oxytocin. This hormone not only helps with the let-down reflex but also helps you bond with your baby and lowers stress levels. High stress can actually inhibit the let-down reflex, making it harder for milk to flow.

Key Takeaway: The most effective way to increase supply is to remove milk more frequently and more thoroughly.

Using Pumping to Boost Your Supply

If you are struggling to increase your supply through nursing alone, or if you are an exclusive pumper, there are specific techniques you can use to send "extra" signals to your body.

One popular method is power pumping. This involves mimicking a baby's cluster feeding (when a baby wants to nurse very frequently for a few hours). To power pump, you pump for 20 minutes, rest for 10, pump for 10, rest for 10, and then pump for a final 10 minutes. This concentrated hour of "demand" can often jumpstart an increase in supply over the course of a few days.

Hydration also plays a major role in pumping success. While drinking gallons of water won't magically create milk if you aren't removing it, being dehydrated can definitely hurt your output. We created our Pumpin' Punch drinks to provide a delicious way to stay hydrated while also getting the benefits of lactation-supporting ingredients. If you want more ideas for drink-based support, our lactation drink mixes collection is another good place to explore.

When to Seek Professional Support

Sometimes, despite your best efforts and the use of supplements, supply issues persist. In these cases, it is important to remember that you do not have to figure this out alone. A Board Certified Lactation Consultant (IBCLC) is a specialist who can help you identify the root cause of the problem.

They can check for things like:

An infant tongue-tie or lip-tie
Positioning and latch issues
Pump flange sizing (which is often overlooked!)
Potential hormonal imbalances in the parent

At Milky Mama, we offer virtual lactation consultations to provide you with personalized, professional support from the comfort of your home. We are here to help you troubleshoot your specific challenges and create a plan that works for your unique situation. If you want hands-on guidance, our Certified Lactation Consultant Breastfeeding Help page is a strong next step.

So, does this famous herbal supplement really work? The answer is that it might for some, but it comes with a long list of potential side effects and inconsistent results. For many parents, the digestive upset and the risk of a supply drop are not worth the gamble.

FAQ

How long does it take for lactation supplements to work?

Most parents begin to see a difference in their milk supply within 24 to 72 hours of starting a supplement, although for some, it may take up to two weeks. It is important to maintain a consistent nursing or pumping schedule during this time to maximize the effects. If you do not see a change after two weeks, you may want to try a different herbal blend or consult an IBCLC. For a deeper look at timing and consistency, our Do Lactation Supplements Work? guide breaks down the basics.

Can certain herbs actually decrease my milk supply?

Yes, some herbs can have the opposite of the intended effect depending on your body's unique chemistry. For instance, about 5% of women in one survey reported a decrease in supply when using the most common traditional lactation herb. Additionally, herbs like peppermint, sage, and parsley are known to potentially lower milk production when consumed in large amounts.

Why does my baby seem gassy when I take lactation supplements?

Many herbal galactagogues contain compounds that can cause gas or digestive upset in the parent, which can then be passed to the baby through breast milk. If the supplement contains high amounts of fiber or specific legumes, it may lead to abdominal discomfort for your little one. Switching to a more gentle, free-from supplement can often help resolve this issue, and our How to Help Low Milk Supply guide has practical next steps when supply concerns and comfort issues overlap.
