Introduction
If you have ever sat up at 3:00 AM, nursing your little one and wondering if they are getting enough, you are certainly not alone. The "supply worry" is one of the most common experiences in early motherhood. We often find ourselves scrolling through forums or asking friends, "Is there something I should be eating to help my body do this?" Among the many suggestions—from oats to lactation cookies—one question frequently swims to the surface: does fish increase milk supply?
In this article, we are going to dive deep into the relationship between seafood and lactation. We will explore the nutritional benefits of fish, specifically focusing on how healthy fats and proteins support your body’s ability to produce liquid gold. We will also cover which types of fish are safest, how to navigate concerns about mercury, and what other "galactagogues" (milk-boosting foods) you can add to your diet. Our goal is to empower you with evidence-based information so you can nourish yourself with confidence, knowing that every drop you produce is a testament to your hard work.
While what you eat plays a role in your overall well-being, the most important thing to remember is that breastfeeding is a journey of partnership between you and your baby. Nutrition is the fuel, but the bond and the physical act of milk removal are the engine. Let’s look at how fish and other nutrient-dense foods can help keep that engine running smoothly.
Understanding the "Supply and Demand" System
Before we look at the specific question of whether fish increases milk supply, it is vital to understand the biological foundation of breastfeeding. At Milky Mama, we always say that breasts were literally created to feed human babies. It is a brilliant, self-regulating system.
When your baby latches or when you use a pump, your body receives a signal to release hormones—specifically prolactin and oxytocin. Prolactin is the "milk-making" hormone, while oxytocin is the "milk-releasing" or "let-down" hormone. The more often milk is removed from the breast, the more milk your body is told to produce. This is the "supply and demand" system.
If you are concerned about your volume, the first step is always to ensure frequent and effective milk removal. However, the quality of your nutrition and your physical health provide the necessary support for this process. This is where your diet comes in. While a single food isn't a magic wand, a body that is well-nourished, hydrated, and rested is much better equipped to meet the demands of a growing baby.
Does Fish Increase Milk Supply? The Nutritional Connection
The short answer is that while fish is not a "magic" galactagogue in the traditional sense (like some herbs), it is one of the most nutrient-dense foods a breastfeeding mother can consume. The nutrients found in certain types of fish can support the hormonal and physical processes required for lactation, which may, in turn, help you maintain a robust supply.
The Role of Omega-3 Fatty Acids (DHA and EPA)
One of the primary reasons fish is often recommended for nursing moms is its high concentration of Omega-3 fatty acids, particularly DHA (docosahexaenoic acid).
- Brain Development: DHA is crucial for your baby’s brain and eye development. Since your baby gets this DHA directly through your milk, your intake directly affects the levels available to them.
- Maternal Wellness: For you, Omega-3s are known to help reduce inflammation and may play a role in supporting mental health and mood stability during the postpartum period. When you feel better emotionally and physically, your stress levels decrease, which is beneficial for your milk let-down reflex.
High-Quality Protein for Tissue Repair
Breastfeeding is an energy-intensive process. Your body requires extra protein to repair tissues after birth and to produce the proteins found in breast milk. Fish is an excellent source of lean, high-quality protein that is easily digestible.
Vitamin D and Iodine
Many breastfeeding mothers are actually deficient in Vitamin D. Salmon and mackerel are some of the few natural food sources of this essential vitamin. Additionally, fish is a great source of iodine, which is necessary for thyroid health. A healthy thyroid is essential for regulating the hormones that control milk production.
Salmon: The "Gold Standard" for Lactation
Salmon is frequently cited as a top food for breastfeeding mothers. It is rich in Omega-3s and is generally considered low in mercury. Many cultures have long traditions of serving fish soups to new mothers to help "bring the milk in." While we need more clinical studies to prove fish directly increases the volume of milk, the combination of healthy fats, protein, and minerals makes it a powerhouse for any lactation-friendly diet.
Choosing the Right Fish: Safety and Mercury Concerns
While fish is wonderful for your health, we have to be mindful of what else might be in the water. Mercury is a heavy metal that can be found in some seafood, and in high amounts, it can be harmful to a baby’s developing nervous system.
Best Choices (Eat 2-3 servings per week)
These fish are generally low in mercury and high in beneficial nutrients:
- Salmon (Wild-caught is often preferred for its nutrient profile)
- Tilapia
- Cod
- Sardines
- Flounder
- Haddock
- Catfish
Good Choices (Limit to 1 serving per week)
- Halibut
- Snapper
- White tuna (Albacore)
Fish to Avoid
You should avoid fish that are high on the food chain, as they tend to accumulate the most mercury:
- King Mackerel
- Shark
- Swordfish
- Tilefish
- Bigeye Tuna
A Note on Local Fish: If you or a friend catch fish in local lakes or rivers, always check local advisories. Some waters may have specific contaminants that make certain fish unsafe for nursing parents.
Practical Ways to Incorporate Fish into Your Routine
We know that when you are caring for a newborn, "cooking a gourmet meal" is usually the last thing on your to-do list. Here are some simple, low-stress ways to get those nutrients:
- Canned Salmon or Sardines: Keep these in your pantry for a quick protein boost on crackers or a salad. It requires zero cooking and is packed with Omega-3s.
- Sheet Pan Dinners: Toss a piece of salmon and some asparagus with olive oil and garlic on a baking sheet. It’s done in 15 minutes and cleanup is easy.
- Fish Tacos: Use white fish like cod or tilapia. It cooks very quickly in a pan and can be topped with pre-shredded cabbage and lime.
Other Foods That Support Your Milk Supply
If you aren't a fan of fish, or if you want to diversify your diet, there are many other traditional galactagogues that can help support your breastfeeding journey. We love incorporating these into our lactation treats because they are both delicious and functional.
Oats and Whole Grains
Oats are perhaps the most famous food for increasing milk supply. They are a great source of iron; low iron levels are a known contributor to low milk supply. Starting your day with a bowl of oatmeal or grabbing one of our Oatmeal Cookies is a great way to fuel your body.
Healthy Fats
Beyond fish, you can find healthy fats in:
- Avocados
- Nuts and Seeds: Almonds, walnuts, and flaxseeds are excellent. If you love a salty-sweet combo, our Peanut Butter Chocolate Chip Cookies are a fan favorite for a reason!
- Olive Oil
Leafy Greens
Spinach, kale, and Swiss chard are packed with phytoestrogens, which may have a positive effect on milk production. They also provide calcium and folate.
Garlic
While it might seem surprising, garlic has been used for centuries to support lactation. Some studies even suggest that babies may stay at the breast longer and latch more effectively when the milk has a slight garlic flavor! You don’t need much—just adding a little to your dinner can be beneficial.
Hydration: The Foundation of Production
You cannot make milk if you are dehydrated. Breast milk is roughly 87% water, which means your fluid needs increase significantly when you are nursing or pumping.
You should aim for about 100 ounces of fluid a day. We know that plain water can get boring, which is why we created our lactation drink mixes. Options like Pumpin Punch™ or Milky Melon™ provide essential hydration along with herbs to support your supply.
Pro-tip: Keep a "hydration station" at your favorite nursing spot. Fill a large water bottle and keep a snack, like our Salted Caramel Cookies, within arm's reach. You deserve to be taken care of while you take care of your baby!
When Food Isn't Enough: Targeted Supplementation
Sometimes, despite eating a balanced diet and nursing frequently, you might feel like your supply needs an extra boost. This is where herbal supplements can be a helpful tool in your kit.
At Milky Mama, we offer a variety of supplements tailored to different needs:
- Pump Hero™: Designed to support those who are pumping frequently.
- Lady Leche™: A wonderful blend for general supply support.
- Dairy Duchess™: Formulated to help with milk enrichment and flow.
- Milk Goddess™: A powerful option for those looking for a significant boost.

Real-Life Challenges: When "Eat This" Feels Hard
It is one thing to read a list of foods; it is another to actually manage your nutrition when you are sleep-deprived and overwhelmed. We want to validate that it is hard to prioritize yourself right now.
Imagine this: You had a rough night. The baby was up every hour, you’re feeling touched out, and the thought of cooking salmon makes you want to cry. In these moments, don't pressure yourself to be perfect. Grab a handful of nuts, drink a glass of Lactation LeMOOnade™, and remember that "every drop counts."
If you are struggling with your supply, it isn't a failure on your part. Sometimes, things like a tongue tie, hormonal imbalances, or returning to work can impact your volume. If you feel like you’ve tried everything and are still struggling, please reach out for professional help. Our virtual lactation consultations are designed to give you personalized, compassionate support from the comfort of your home.
The Importance of Self-Care and Rest
While the question "does fish increase milk supply" focuses on what goes into your mouth, your milk supply is also heavily influenced by what is happening in your mind and body.
Cortisol vs. Oxytocin
Stress produces cortisol, which can inhibit the let-down reflex. This doesn't mean you aren't making milk; it means the milk is having a harder time leaving the breast. This is why you might notice you pump less when you are stressed or in a rush.
- Try to relax: Before nursing or pumping, take three deep breaths.
- Skin-to-skin: Cuddling your baby skin-to-skin is one of the fastest ways to boost your oxytocin levels.
- Sleep (when possible): We know "sleep when the baby sleeps" is often impossible, but even a 20-minute rest can help your body reset.

Addressing Perceived Low Supply
Sometimes, moms think their supply is low when it is actually perfectly normal. It is helpful to know the signs of "perceived" low supply versus "actual" low supply.
It might NOT be low supply if:
- Your breasts feel softer than they did in the first few weeks (this just means your supply has regulated!).
- Your baby is "cluster feeding" (this is a normal way for babies to naturally increase your supply).
- Your baby is fussy in the evening (the "witching hour" is very common).
- You can't pump much after a nursing session (your baby is much more efficient than a pump).
It MIGHT be low supply if:
- Your baby is not gaining weight according to their pediatrician's growth curve.
- Your baby has fewer than 6 heavy wet diapers in a 24-hour period (after the first week).
- Your baby seems lethargic or is not hitting developmental milestones.
If you have concerns, our Breastfeeding 101 class is a fantastic resource for learning how to read your baby’s cues and understand your body’s signals.
Cultural Traditions and Breastfeeding
Around the world, different cultures have their own "magic" foods for breastfeeding.
- In many Asian cultures, fish and papaya soup is a staple for new mothers.
- In Latin American cultures, beverages like atole (a warm corn-based drink) are often suggested.
- In many African cultures, starchy foods like yams and special porridges are used.
What all of these traditions have in common is a focus on warming, nourishing, and hydrating the mother. They remind us that the postpartum period is a time for the community to "mother the mother." While the science on "does fish increase milk supply" looks at DHA and protein, the cultural side looks at comfort and care. Both are equally important!

FAQ
1. Does eating fish really increase the amount of milk I make? While there is no single food that is guaranteed to increase milk volume for everyone, fish like salmon are packed with high-quality protein and Omega-3 fats that support the hormonal health necessary for lactation. For many moms, a nutrient-dense diet that includes fish helps their bodies function optimally, which can positively impact supply.
2. Is it safe to eat fish while breastfeeding if I'm worried about mercury? Yes, it is safe and actually recommended by experts! The key is to choose fish from the "Best Choices" list, such as salmon, tilapia, cod, and sardines. These are low in mercury and high in the DHA your baby needs for brain development. Avoid high-mercury fish like swordfish or king mackerel.
3. Can I take a fish oil supplement instead of eating fish? Fish oil supplements can be a great way to get your Omega-3s if you don’t like the taste of fish. However, whole fish also provides protein, Vitamin D, and iodine which you won't get from a pill. If you choose a supplement, look for a high-quality, purified version. We also offer herbal supports like Pumping Queen™ that focus on other aspects of supply.
4. Will eating fish make my breast milk taste like fish? Strong flavors like garlic, mint, or vanilla can sometimes subtly change the scent or taste of breast milk, but most babies don't mind. In fact, exposure to various flavors in breast milk may help your baby be more open to different foods when they start solids. Unless your baby is showing signs of an allergy or extreme fussiness, there is no need to avoid flavorful foods.
