If you have ever spent a late night scrolling through breastfeeding forums, you have likely seen mention of lactation cookies. These treats are more than just a standard snack. They are formulated with specific ingredients designed to support a nursing parent's milk production. For many, the idea of eating a cookie to help with breastfeeding sounds too good to be true, but there is a logic behind the recipe.
At Milky Mama, we know that the early days of breastfeeding can be both beautiful and overwhelming. Whether you are worried about your supply or just looking for a convenient, nutrient-dense snack, understanding what you are putting into your body is essential. This post will break down the functional ingredients found in these cookies and explain how they may support your lactation journey. We will explore the science behind galactagogues and why these specific components are chosen by lactation professionals.
To understand what is in a lactation cookie, you first need to know the term "galactagogue." A galactagogue is a substance that may help increase breast milk production in humans and other mammals. These can be found in the form of certain foods, herbs, or even medications.
While the word sounds clinical, galactagogues have been used for centuries in various cultures to support new mothers. In a lactation cookie, the recipe usually centers around three primary food-based galactagogues: oats, brewer’s yeast, and flaxseed. For a deeper look at these ingredients, read what makes lactation cookies work.
It is important to remember that while these ingredients can be supportive, they work best when paired with frequent milk removal. Breastfeeding operates on a supply-and-demand system. The more often your baby nurses or you pump, the more milk your body is signaled to create. Lactation treats are meant to support this biological process, not replace it.
Oats are the foundation of almost every lactation cookie recipe. They are a complex carbohydrate, meaning they provide steady energy rather than a quick sugar spike. This is vital for breastfeeding parents who often experience extreme hunger and fatigue.
One of the main reasons oats are included is their high iron content. There is a known link between low iron levels (anemia) and a decreased milk supply. If a mother’s iron stores are depleted after birth, her body may struggle to maintain a robust supply. By consuming iron-rich foods like oats, you may help support your body’s ability to produce milk.
Oats also contain a type of fiber called beta-glucan. Research suggests that beta-glucan can raise the levels of prolactin in the blood. Prolactin is the primary hormone responsible for milk synthesis (the process of making milk). When prolactin levels are supported, the body receives a clear signal to keep the milk coming.
Oats are rich in saponins. These are plant-based compounds that may have a positive effect on the immune system. They are also thought to influence the hormones related to milk production. Using old-fashioned rolled oats or steel-cut oats is usually preferred over instant oats, as they are less processed and retain more of their nutritional value.
Brewer’s yeast is perhaps the most famous ingredient in lactation treats. It is a traditional galactagogue that has been used for generations. It is not the same as the yeast you use to bake bread or the nutritional yeast you might sprinkle on popcorn. Brewer’s yeast is a byproduct of beer brewing, though the version used in supplements and cookies is usually "de-bittered" to make it more palatable.
Brewer’s yeast is packed with B-complex vitamins, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), and B9 (folic acid). These vitamins are essential for energy metabolism. Breastfeeding burns an average of 300 to 500 extra calories a day. The B vitamins in brewer’s yeast help your body convert those calories into usable energy, which can help combat the "mom fog" and exhaustion.
Beyond vitamins, brewer’s yeast contains chromium, selenium, and protein. Chromium is a trace mineral that helps maintain stable blood sugar levels. For a nursing parent, stable blood sugar means fewer energy crashes and a more consistent mood. Selenium is an antioxidant that supports thyroid function, which is closely tied to hormonal balance and lactation.
Key Takeaway: Brewer’s yeast provides the nutritional "heavy lifting" in a lactation cookie, offering a dense source of B vitamins and minerals that support both the mother's energy and her milk production.
Flaxseed is another staple ingredient. To get the benefits, the flaxseed must be ground. Whole flaxseeds often pass through the digestive system untouched, meaning you won’t absorb the nutrients inside.
Flaxseeds contain lignans, which are a type of phytoestrogen. Phytoestrogens are plant-based compounds that can mimic or modulate the effects of estrogen in the body. Since breastfeeding is a hormone-driven process, the gentle support provided by these plant compounds can be beneficial for some parents.
Flaxseed is one of the best plant-based sources of alpha-linolenic acid (ALA), an omega-3 fatty acid. These healthy fats are crucial for the development of your baby’s brain and nervous system. While the fat content of your milk remains relatively stable regardless of your diet, the type of fat can be influenced by what you eat. Including flaxseed in your diet ensures your milk is rich in these essential fatty acids.
The fiber in flaxseed also helps with digestion. Many postpartum parents struggle with digestive regularity, and the added fiber from flax and oats can provide much-needed relief. A healthy gut allows for better nutrient absorption, which indirectly supports your overall well-being and milk supply.
While oats, yeast, and flaxseed do the work, other ingredients are added to make the cookie taste good and provide additional calories. Breastfeeding is not a time for restrictive dieting. Your body needs fuel to produce milk.
Most lactation cookies use butter or coconut oil. Coconut oil is particularly popular because it contains medium-chain triglycerides (MCTs). These fats are easily digested and provide an immediate energy source. Some studies suggest that consuming coconut oil can increase the levels of lauric acid and capric acid in breast milk, which have antimicrobial properties that help protect your baby.
Cane sugar, brown sugar, or maple syrup are often used to balance the slightly bitter taste of the brewer’s yeast. While you don't want to overdo the sugar, these carbohydrates provide a quick energy boost. This can be especially helpful during those middle-of-the-night feeding sessions when you are feeling depleted.
Many recipes, including our own formulations at Milky Mama, may include almond butter or peanut butter. These add protein and healthy fats, making the cookie more satiating. Protein is a building block for every cell in your body and plays a role in the production of breast milk.
It is a common misconception that lactation cookies only work because of the "magic" ingredients. In reality, they work through a combination of nutritional support and psychological well-being.

Every body is different. While many parents report a noticeable increase in their milk volume after adding lactation cookies to their routine, others may see a more modest change. Lactation is a complex biological process influenced by genetics, stress levels, hydration, and how often the breast is emptied.
If you are experiencing a significant drop in supply or your baby is not gaining weight, it is always best to consult with a certified lactation consultant or your healthcare provider. They can help identify any underlying issues, such as a poor latch or hormonal imbalances, that a cookie alone cannot fix. Milky Mama’s breastfeeding help and lactation consultations can provide personalized support for concerns such as low milk supply, pumping, latch, engorgement, and mastitis.

Many expectant parents wonder if they should start eating lactation cookies before the baby arrives. While the ingredients are safe to eat during pregnancy, they are most effective once your milk has officially "come in" (Lactogenesis II). This typically happens three to five days after birth.
Once your mature milk is present, the galactagogues can begin to support the hormonal signals required to maintain and increase that supply. However, there is no harm in having a batch ready in the freezer for your first week home!

While what's in a lactation cookie is important, it is only one piece of the puzzle. To get the most out of your lactation treats, consider these other evidence-based strategies:
Holding your baby skin-to-skin (chest-to-chest with no clothing between you) triggers a massive release of oxytocin. This hormone not only helps you bond but also tells your breasts to release milk. It is one of the most effective ways to boost supply naturally.
If you are looking to mimic a baby’s cluster feeding (when a baby wants to nurse very frequently for a period of time), you can try power pumping. This involves pumping for 20 minutes, resting for 10, pumping for 10, resting for 10, and pumping for 10. Doing this once a day for a few days can signal your body that it needs to produce more milk.
If the baby is not removing milk efficiently due to a poor latch, your body will think the baby doesn't need as much milk and will slow down production. Ensuring a deep, comfortable latch is the best way to keep your supply steady. Parents looking for broader breastfeeding education can explore the Breastfeeding 101 online course.
Most ingredients in lactation cookies are considered "GRAS" (Generally Recognized as Safe) by the FDA. However, because everyone's body is unique, it is wise to introduce them slowly.

Yes, they are perfectly safe for anyone to eat. The ingredients like oats, flaxseed, and brewer's yeast are nutritious for all people, and they will not cause a non-nursing person to start producing milk. Milk production requires specific hormones like prolactin and oxytocin, which are typically only present in high amounts after childbirth.
Most parents find that eating one to two cookies or servings per day is sufficient to see a benefit. It is best to start with a smaller amount to see how your body and your baby react to the ingredients. If you feel you need more support, you can increase your intake while monitoring for any digestive changes.
Many parents report seeing a difference in their milk supply within 24 to 72 hours of consistent consumption. However, results vary from person to person. For the best outcome, ensure you are also nursing or pumping frequently to stimulate the demand for more milk. You can review additional product questions in the Milky Mama FAQ.
Yes, lactation cookies freeze very well. You can freeze the raw dough in pre-scooped portions or freeze the fully baked cookies in an airtight container for up to three months. This is a great way to prep for the postpartum period so you always have a supportive snack ready when you need it most.
