Introduction

It is 3:00 AM, and you are staring at the pump parts on your nightstand. You have tried the cookies, the teas, and the tinctures, yet the numbers on the bottle aren't moving. In fact, they might even be going down. It is a frustrating and lonely feeling when you are doing everything "right" but your body isn't responding the way you expected. At Milky Mama, we hear this story from exhausted parents every single day.

You might have started taking a popular herbal supplement because you heard it was the gold standard for milk production. However, you are now noticing a dip in your output and wondering what went wrong. This article explores why some parents experience a decrease in supply while using this specific herb and what you can do to get your journey back on track. We will look at the science of lactation and why your unique biology matters when choosing support.

The History of This Common Lactation Herb

For many years, one specific seed has dominated the world of breastfeeding supplements. It is an herb often found in Mediterranean and Middle Eastern cooking. It has a very distinct scent that many people compare to maple syrup. Because it has been used for generations in various cultures, it became the default recommendation for anyone worried about their milk supply.

In the early days of modern lactation support, there were very few commercial options available. This herb was inexpensive and easy to find in health food stores. Because some small studies suggested it might help some people, it quickly became the primary ingredient in almost every lactation tea and capsule on the market. It was essentially the only choice for a long time.

However, just because something is traditional does not mean it is right for every body. Breastfeeding is a complex hormonal process. What works for one person may not work for another. As we have learned more about how hormones and metabolism affect lactation, we have realized that this "one-size-fits-all" approach has some significant flaws.

Can This Supplement Actually Lower Your Milk Supply?

The short answer is yes, for some people, taking this specific herbal supplement can lead to a decrease in milk production. While it is marketed as a way to boost supply, it does not interact well with everyone’s unique physiology. For a significant number of parents, it can have the opposite effect of what they intended.

When you take a galactagogue—which is a substance that helps increase milk production—you are trying to support your body's natural processes. But if that substance interferes with your underlying health or your hormonal balance, it can cause your supply to stall or even drop. It is not a failure on your part. It is often just a mismatch between the supplement and your biological needs.

Many lactation consultants have observed that parents who do not see an increase within the first 72 hours of taking the herb often never see one. In some cases, the body responds to the herb as a stressor. When your body is under stress, it may prioritize other functions over milk production. This can lead to a noticeable dip in the amount of milk you are able to pump or provide at the breast.

For additional guidance on evaluating supplements and dosage, you can read this guide to dosing lactation supplements.

The Impact on Thyroid Health

One of the most common reasons this herb can cause a drop in supply is its interaction with the thyroid gland. Your thyroid is a small, butterfly-shaped gland in your neck that acts as the "master controller" for your metabolism. It plays a huge role in how much milk you produce.

If you have an overactive or underactive thyroid, your milk supply can be very sensitive to changes. Some clinical observations suggest that this particular herb can interfere with thyroid function or the way thyroid medication is absorbed. If your thyroid levels become unbalanced, your milk production is often one of the first things to suffer.

Many parents are not even aware they have a thyroid issue until they start breastfeeding. The demands of postpartum recovery can put a lot of strain on this gland. If you notice that your supply dropped after starting a supplement and you also feel excessively tired, cold, or have dry skin, it may be worth talking to your doctor about your thyroid levels.

Insulin Resistance and Blood Sugar

Another major factor in how this herb affects your supply is your blood sugar. This supplement is known to lower blood glucose levels. While this might sound like a good thing, it can be problematic for breastfeeding parents, especially those with conditions like PCOS (Polycystic Ovary Syndrome) or insulin resistance.

Milk production requires a lot of energy and a stable metabolic environment. If your blood sugar drops too low or fluctuates wildly because of a supplement, your body may struggle to maintain a consistent milk supply. For parents with PCOS, the hormonal landscape is already delicate. Adding an ingredient that aggressively alters blood sugar can throw off the balance of prolactin and oxytocin.

Key Takeaway: If you have a history of blood sugar issues or PCOS, you should be very cautious with supplements that are known to lower glucose, as they may negatively impact your production.

Why Your Body Might React Negatively

Every body is different, and the way we process herbs varies from person to person. Some people have a high sensitivity to the compounds found in this specific seed. Instead of stimulating the mammary glands, the herb might cause systemic inflammation or digestive distress.

There is also the "placebo" factor to consider. If you are taking a supplement that makes you feel unwell, your stress levels will rise. High levels of cortisol—the stress hormone—can actively inhibit the let-down reflex. The let-down reflex is what allows your milk to flow from the small sacs in your breast through the ducts to your baby. If you can't let down effectively, your breasts won't be emptied, and your body will stop making as much milk.

We always tell our families that breastfeeding is a "supply and demand" system. If a supplement makes you or your baby feel too sick to nurse or pump effectively, the demand decreases. When the demand goes down, the supply naturally follows. This is why it is so important to listen to your body and your baby.

Potential Side Effects for the Nursing Parent

Beyond the risk of low milk supply, this herb is famous for several other side effects. The most common one is the "maple syrup" odor. The herb contains a compound called sotolon, which passes through your sweat and urine. While smelling like a pancake house might seem harmless, it is often a sign that you are taking a very high dose.

Other common side effects for parents include:

  • Stomach upset and cramping
  • Loose stools or diarrhea
  • Increased gas and bloating
  • Headaches
  • Allergic reactions, especially if you are allergic to peanuts or chickpeas

These symptoms can make the already difficult newborn phase feel even more overwhelming. If you are constantly running to the bathroom or feeling bloated, it is hard to focus on bonding and feeding your baby. Your well-being matters just as much as your milk supply, and you shouldn't have to suffer through physical discomfort to feed your little one.

How the Supplement Affects Your Baby

Because many of the compounds in herbal supplements pass into breast milk, your baby can experience side effects too. Some parents notice that their babies become much more fussy or gassy after the parent starts taking this specific herb. A baby with a tummy ache is a baby who may struggle to latch or stay at the breast long enough for a full feed.

If your baby is dealing with gas or diarrhea because of a supplement you are taking, they may become frustrated at the breast. This can lead to shorter feeding sessions. Over time, these shorter sessions tell your body that the baby needs less milk. This creates a downward spiral where your supply continues to drop because the baby is not removing enough milk.

We believe that breastfeeding should feel as comfortable as possible for both you and your baby. If you notice a change in your baby's behavior, stool consistency, or gas levels after starting a new supplement, it is a good idea to pause and see if things improve. You're doing an amazing job, and it is okay to change your approach if something isn't working.

The Real Secret to Milk Supply: Supply and Demand

It is tempting to look for a magic pill or a special tea to fix supply issues. However, the most effective way to make more milk is through frequent and effective milk removal. This is known as the law of supply and demand. The more milk that leaves the breast, the more milk your body will make to replace it.

When the breast is full, it sends a signal to your brain to slow down production. When the breast is empty, it sends a signal to speed up. No supplement can replace this fundamental biological process. If you are taking a supplement but not nursing or pumping frequently, you likely won't see the results you want.

If you are worried about your supply, the best first step is to increase the number of times you remove milk. This might mean adding a pumping session, practicing skin-to-skin contact, or trying "power pumping." Power pumping mimics a baby's cluster feeding and can be a very effective way to signal your body to produce more. This guide to helping low milk supply offers additional strategies.

Every drop counts. Whether you are providing an ounce or a gallon, you are giving your baby incredible benefits. Focus on frequent removal rather than just supplements.

Better Alternatives for Lactation Support

If you have decided that the traditional maple-scented herb isn't right for you, don't worry. There are many other evidence-based ingredients that can support your lactation journey without the common side effects. We have spent years researching and formulating products that avoid the ingredients that cause the most issues for parents.

Some of our favorite alternative ingredients include:

  • Goat’s Rue: This herb is excellent for supporting the development of mammary tissue. It is often recommended for parents who didn't see much breast change during pregnancy.
  • Moringa: Often called a "superfood," Moringa is packed with iron and vitamins. It has been used for centuries to support healthy milk production.
  • Blessed Thistle: This herb is frequently used to support the hormones responsible for milk flow. It is often more gentle on the stomach than other options.
  • Black Seed: This is a powerful antioxidant that supports overall wellness and can help with supply consistency.

At Milky Mama, we focus on these alternatives because they tend to be better tolerated by both parents and babies. Our Emergency Lactation Brownies, for example, use a blend of ingredients like oats, flaxseed, and brewer's yeast to support you without the risk of the supply drop some experience with other herbs. We want you to feel nourished and supported, not gassy and frustrated.

What to Do if Your Supply Has Dropped

If you suspect that a supplement has caused your milk supply to decrease, the first step is to stop taking it. Most parents find that the herb clears their system within a day or two. Once it is out of your system, you can focus on rebuilding your supply using gentle, proven methods.

Here is a quick action plan to help you bounce back:

  1. Stop the Supplement: If it’s making you or the baby feel unwell, put it aside.
  2. Hydrate: Drink plenty of water and electrolyte-rich fluids. Our Lactation LeMOOnade™ can help you stay hydrated while providing a little extra support.
  3. Increase Nursing/Pumping: Try to add one or two extra sessions a day for a few days.
  4. Skin-to-Skin: Spend time snuggling your baby. This releases oxytocin, which helps with milk flow.
  5. Check the Latch: Sometimes low supply is actually a latch issue. Ensure your baby is removing milk effectively.

Remember, your well-being matters. If you are stressed and exhausted, it is harder for your body to do its job. Take a deep breath and know that one dip in supply doesn't mean the end of your breastfeeding journey. You have options, and support is available.

When to Seek Professional Lactation Support

While educational content is helpful, it is not a substitute for personalized care. If you are struggling with your supply, we always recommend reaching out to a certified lactation consultant (IBCLC). They can look at your specific situation, check your baby's latch, and help you create a plan that works for your unique goals.

You should consider booking a consultation if:

  • Your baby is not gaining weight appropriately.
  • You are experiencing significant pain while nursing.
  • Your supply has dropped suddenly and hasn't returned after a few days of frequent removal.
  • You have a medical condition like PCOS or a thyroid disorder that complicates breastfeeding.

We offer virtual lactation consultations to make professional support accessible from the comfort of your own home. Having an expert in your corner can take a huge weight off your shoulders. They can help you navigate which supplements are safe for you and which ones you should avoid based on your health history.

How to Choose the Right Support Products

When looking for lactation treats or supplements, it is important to read the labels carefully. Many products use the same traditional herb because it is cheap, even if it isn't the most effective for everyone. Look for products that prioritize high-quality ingredients and are formulated by professionals who understand the clinical side of lactation.

Our founder, Krystal Duhaney, is an RN, BSN, and IBCLC. She created our line because she saw a need for better, safer support. Whether you choose our lactation cookies or our herbal tinctures like Lady Leche™ or Pumping Queen™, you can trust that they are made with your health and your baby’s comfort in mind. We believe that breastfeeding support should feel empowering, not like a gamble with your supply.

Every person's journey is different. Some people may find that they don't need supplements at all, while others find them to be a helpful tool in their kit. The goal is to find what makes you feel your best and helps you meet your feeding goals, whatever they may be.

Normalizing the Challenges of Breastfeeding

Breastfeeding is natural, but it doesn't always come naturally. It is a learned skill for both you and your baby. It is completely normal to face hurdles along the way. If you have experienced a supply drop because of a supplement, please don't feel guilty. You were trying to do what was best for your baby, and you just happened to encounter a common side effect.

We want to normalize the fact that supply can fluctuate. It can be affected by your period, a cold, stress, or even just a busy few days where you didn't drink enough water. The key is to have the tools and the knowledge to handle those fluctuations when they happen. You are doing the work, and that is what matters most.

"You're doing an amazing job. Breasts were literally created to feed human babies, but sometimes they just need a little extra gentle encouragement."

Moving Forward With Confidence

As you move forward, focus on the things you can control. Focus on your nutrition, your hydration, and your connection with your baby. If you want to use herbal support, look for alternatives that are less likely to cause a dip in production or digestive issues.

You have the strength to navigate these challenges. By learning how your body works and what ingredients support it best, you can build a sustainable and happy breastfeeding relationship. Whether you are breastfeeding for a month or two years, your commitment to your baby’s health is incredible.

We are here to support you every step of the way. From our educational blog posts to our community of supportive parents, you don't have to do this alone. Trust your instincts, listen to your body, and know that we are cheering you on.

FAQ

Can taking certain herbs really decrease my milk supply?

Yes, for some individuals, certain herbs can interfere with hormonal balance or underlying health conditions like thyroid disorders, leading to a drop in production. If you notice a decrease after starting a new supplement, it is best to stop and consult a lactation professional.

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

Many common lactation herbs can cause digestive upset, which can pass through your breast milk to your baby. This can lead to increased gas, fussiness, or changes in stool, which may make the baby less interested in nursing.

Is it true that I need to smell like maple syrup for a supplement to work?

The maple syrup smell is a common side effect of one specific herb, but it is not a requirement for milk production. In fact, many effective galactagogues like Moringa or Goat's Rue do not cause any change in body odor while still providing support.

How quickly will my supply return after I stop an unsuccessful supplement?

Most parents see an improvement within 24 to 48 hours after stopping a supplement that wasn't working for them. Once the herb is out of your system, focusing on frequent milk removal through nursing or pumping will help your supply bounce back.
