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 or if the hype is simply a result of tradition over science.

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 and effectively. 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.

This article explores the evidence regarding traditional lactation herbs, the biological foundations of milk production, and safer alternatives for those looking to boost their supply.

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 (a process called 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 so it can be accessed by the baby.

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. In the world of lactation, a placebo effect can be very strong because stress levels significantly impact milk flow. If a parent believes a supplement will work, their stress may decrease, allowing their milk to flow more easily.

For example, one 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, other reviews found no strong evidence to support its use as a reliable tool for every parent. 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, such as Maple Syrup Urine Disease (MSUD), which can lead to unnecessary medical testing and significant parental anxiety.

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 has been known to lower blood sugar levels, a condition called 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. Because thyroid function is closely tied to milk production, an herb that disrupts this balance could unintentionally cause supply to drop.

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 when starting any new herb.

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 before taking traditional lactation supplements.

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

Why We Choose 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 made this choice based on her clinical experience as an IBCLC and a Registered Nurse. We believe that breastfeeding support should be inclusive and as safe as possible for a wide variety of parents.

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 but offer a different safety profile. We believe in providing nourishing support that feels good for both you and your little one. Our products are formulated to be gentle on the stomach while still providing the lactation support parents are looking for.

Better Alternatives for Lactation Support

If you are looking for ways to support your supply without the risks associated with the most common herbal supplements, there are many other options available. You can explore Milky Mama’s lactation supplement collection to compare available formulas.

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. Because it is so nutrient-dense, it also helps the parent stay nourished during the demanding postpartum period. 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. Unlike some other herbs, Alfalfa is generally very well-tolerated by both parents and babies. We include Alfalfa in our Dairy Duchess™ supplement to provide a gentle boost to the supply while offering essential nutrients.

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. It is believed to support the digestive system as well, which can be helpful for postpartum recovery.

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 several of our supplement blends, including Dairy Duchess™.

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, regardless of what supplements you are taking.

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.

For additional pumping guidance, see this complete guide to how often you should pump.

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 the milk to leave the breast.

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

Identifying True Low Supply

Many parents worry about their supply when their baby’s behavior changes, but these changes are often a normal part of infant development. It is important to distinguish between "perceived" low supply and "actual" low supply.

Common Misconceptions

Cluster Feeding: When a baby wants to eat every hour, it doesn't necessarily mean you're out of milk. It is often the baby's way of naturally increasing your supply for a growth spurt.
Softer Breasts: Around 6 to 12 weeks, your milk supply regulates. Your breasts may no longer feel "full" or "engorged," but this just means your body is making exactly what the baby needs.
The Pump Output: What you pump is not always an accurate reflection of what your baby gets. Babies are much more efficient at removing milk than a machine.

Signs of Actual Low Supply

If you are concerned, look at the baby's output and growth rather than your own physical sensations.

Diaper Count: A well-hydrated baby should have at least 6 heavy wet diapers and 3 or more bowel movements in a 24-hour period (though bowel frequency can change as they get older).
Weight Gain: Your pediatrician will track the baby's growth curve. Steady weight gain is the best indicator that they are getting enough milk.
Lethargy: A baby who is extremely sleepy and difficult to wake for feeds should be evaluated by a healthcare provider immediately.

Practical Steps to Support Your Journey

If you have determined that you would like to support your supply, we recommend a holistic approach. Supplements are just one piece of the puzzle.

Hydrate and Nourish: Milk is mostly water. Staying hydrated is essential. Our Lactation LeMOOnade™ or Pumpin’ Punch™ are great ways to stay hydrated while also getting lactation-supportive ingredients. Browse the lactation drink mix collection for available options.
Check Your Pump Parts: If you are a pumper, ensure your breast shields (flanges) are the correct size. Using the wrong size can lead to tissue damage and ineffective milk removal. Also, replace your valves and membranes every 4 to 8 weeks.
Power Pumping: This is a technique designed to mimic a baby’s cluster feeding. You pump for 20 minutes, rest for 10, pump for 10, rest for 10, and pump for 10. Doing this once a day for a few days can signal your body to increase production.
Reach Out for Support: A Virtual Lactation Consultation can help you identify latch issues, flange sizing problems, or other hurdles that might be affecting your supply. Book breastfeeding help with a lactation consultant when you want personalized guidance.

Conclusion

When asking if certain herbs really help milk supply, the answer is that it depends on the individual. While traditional remedies have been used for a long time, the potential for side effects like digestive upset, thyroid interference, and blood sugar drops makes them a less-than-ideal choice for many parents.

At Milky Mama, we believe in providing support that is grounded in clinical expertise and parental comfort. By focusing on nutrient-dense alternatives like Moringa and Alfalfa, and prioritizing the biological "demand and supply" cycle, you can support your lactation journey with confidence.

Focus on frequent and effective milk removal.
Choose supplements that align with your overall health needs.
Trust your baby’s growth and diaper counts over your pump output.

You are doing an amazing job, and every drop counts. Your well-being matters just as much as your milk supply, so choose the path that feels best for both you and your baby.

FAQ

Does every woman experience side effects from traditional lactation herbs?

No, not every person will have a negative reaction. However, side effects like gas, bloating, and the distinct maple syrup odor are very common, and those with thyroid issues or diabetes should be especially cautious.

How long does it take to see a change in supply when using supplements?

Many parents notice a difference within 24 to 72 hours of starting a supplement, but for others, it may take up to a week. Consistency is key, and supplements should always be used in conjunction with frequent nursing or pumping.

Can I take lactation supplements if I have a peanut allergy?

If the supplement contains herbs from the legume family, such as the maple-scented herb often discussed, there is a risk of cross-reactivity. It is safer to choose supplements that are specifically formulated to be free from those ingredients if you have a known legume allergy.
