If you have ever finished a breastfeeding or pumping session and felt like you just trekked across a desert, you are not alone. That intense, sudden thirst is a real biological signal. Our bodies use a significant amount of fluid to produce breast milk, and staying hydrated is one of the most basic yet vital ways to support your journey. While many factors influence your output, what you choose to drink can play a supportive role in how you feel and how much milk you produce.
At Milky Mama, we know that breastfeeding is a beautiful process, but it doesn't always come naturally. You might hear stories about "magic drinks" that instantly boost supply, but the primary driver of milk production is the frequent and effective removal of milk. If you want a deeper starting point on the mechanics behind feeding and supply, our Breastfeeding 101 course is a helpful place to begin. This post explores which drinks may help, the science behind lactation-friendly ingredients, and how to keep your hydration levels optimal. Every drop counts, and your well-being matters just as much as your baby’s.
It is a common myth that drinking gallons of water will automatically create an oversupply. However, the opposite is true: being dehydrated can definitely cause a dip in your milk volume. When your body is low on fluids, it prioritizes your vital organs and survival over milk production. This is why maintaining a steady intake of liquids is so important for nursing parents.
Breast milk is roughly 87% to 90% water. If you aren't replacing the fluids your body uses to feed your baby, you may notice you feel more fatigued or that your "let-down" (the reflex that releases milk from the breast) feels slower. Proper hydration helps maintain your blood volume and ensures that the hormones responsible for milk production can travel effectively through your system.
Beyond just water, your body needs electrolytes like sodium, potassium, and magnesium. These minerals help your cells absorb and use the water you drink. If you are drinking plain water but still feel thirsty, you might need a boost of these minerals to help your body actually stay hydrated.
When parents ask what drinks increase milk supply, they are often looking for more than just water. Some ingredients are known as galactagogues. A galactagogue is a substance—usually a food, herb, or drink—that is believed to help increase milk production. Here are the most common beverages parents turn to when looking for a boost.
Coconut water has become a favorite in the breastfeeding community for good reason. It is naturally rich in potassium, which is a key electrolyte that helps with hydration. Unlike many sports drinks, it is usually lower in added sugars and provides a refreshing way to replenish fluids.
Many parents find that sipping on coconut water during or after a pumping session helps them feel more energized. The natural sweetness can also provide a small energy boost during those long middle-of-the-night feeds. It is essentially nature’s version of an electrolyte drink.
You have likely heard that oatmeal is great for supply. This is because oats contain beta-glucans. Beta-glucans are a type of fiber that can help increase the levels of prolactin in your body. Prolactin is the hormone primarily responsible for telling your body to make milk.
Drinking oat milk or oat-based smoothies can be a convenient way to get these benefits on the go. Oat milk is also a great dairy-free alternative for parents whose babies may be sensitive to cow's milk protein. While drinking oat milk isn't exactly the same as eating a bowl of thick-cut oats, it still offers supportive nutrients and hydration.
Barley is another grain that is incredibly high in beta-glucans. In many cultures, barley water is the "gold standard" for increasing milk supply. It is made by simmering barley pearls in water, straining the liquid, and often flavoring it with a bit of lemon or honey.
Malted beverages, which are made from sprouted barley, are also frequently recommended. The malt contains enzymes and carbohydrates that may support the hormones needed for lactation. Some parents find that a warm malted milk drink before bed helps them relax and supports their supply for the next morning’s feed.
You may have seen parents on social media swearing by specific colors of sports drinks. While the color of the drink doesn't actually matter, the electrolytes and calories do. If a parent is struggling with supply because they are dehydrated and under-eating, a drink that provides quick glucose (sugar) and salts can help their body recover quickly.
The "boost" many people feel from these drinks often comes from the sudden influx of hydration and energy. If you choose these, try to look for options that aren't loaded with artificial dyes or excessive sugar, or balance them out with plenty of plain water.
Herbal teas have been used for centuries to support breastfeeding. Common ingredients include moringa, alfalfa, and blessed thistle. These herbs are thought to support the mammary tissue and hormonal balance.
One thing to keep in mind is that herbal tea is most effective when consumed consistently. Drinking one cup once a week likely won't make a big difference, but incorporating a few cups into your daily routine may help. If you want to compare herbal options more closely, our lactation supplements collection can be a useful next stop.
Key Takeaway: While no drink is a "magic fix," beverages that include electrolytes, beta-glucans (from oats or barley), and supportive herbs can help your body stay hydrated and nutritionally supported for milk production.
We understand that busy parents need options that are both effective and delicious. We created our line of lactation drinks to take the guesswork out of choosing what to sip on during the day. Our drinks are designed to provide hydration while incorporating ingredients that support lactation.
If you want to browse the full range, start with our lactation drink mixes. For a fruity option that many parents reach for during pumping sessions, Pumpin Punch™ is one of our most popular choices.
Our drinks are formulated with the needs of breastfeeding parents in mind, focusing on hydration and traditional galactagogues to help you feel your best. We believe that supporting your supply should be something you actually look forward to doing.
Just as some drinks can support your supply, others might hinder it if consumed in excess. It is important to listen to your body and watch for any reactions in your baby.
Most breastfeeding parents can safely enjoy a cup or two of coffee. However, very high levels of caffeine can lead to dehydration because caffeine is a mild diuretic (it makes you pee more). Additionally, some babies are very sensitive to caffeine and may become fussy or have trouble sleeping if you consume too much. If you notice a dip in supply or a very restless baby, you might try scaling back your caffeine intake to see if it helps.
In large quantities, certain herbs are actually used to help parents dry up their milk supply during weaning. Peppermint, sage, and parsley are the most common culprits. While a peppermint candy or a bit of parsley as a garnish is usually fine, avoid drinking large amounts of peppermint tea or taking sage supplements if you are trying to maintain or increase your supply.
There is an old myth that drinking beer helps with milk supply because of the hops and barley. While barley is supportive, alcohol itself can actually inhibit the let-down reflex. It can also dehydrate you. If you choose to have a drink, it is best to do so in moderation and ensure you are drinking plenty of water alongside it.
While an occasional soda won't hurt, relying on them for hydration isn't ideal. The high sugar content can lead to energy crashes, and the carbonation can sometimes make you feel full before you've actually consumed enough hydrating fluids.
Knowing what to drink is only half the battle; the other half is actually remembering to drink it! When you are caring for a newborn, it is easy to forget your own basic needs. Here are some practical ways to stay on top of your hydration:
If you are still trying to figure out the rhythm of pumping, our article on how to keep milk supply up when pumping can help you connect hydration with your pumping routine.
While we are focusing on drinks today, it is essential to remember that breastfeeding is primarily a "supply and demand" system. The more often and more effectively you remove milk from your breasts, the more milk your body will make.
If you are drinking all the right things but not nursing or pumping frequently enough, your supply will likely remain the same. The breasts were literally created to feed human babies, and they respond best to the physical stimulation of a baby or a pump.
Think of lactation drinks as the "fuel" for the factory. You need the fuel to run the machines, but the machines won't start unless the "orders" (the baby nursing or the pump) come in.

Sometimes, we worry about our supply even when things are going perfectly. It is normal to feel like your breasts are "softer" after the first few weeks; this just means your supply has regulated, not that it has disappeared.
You can feel confident your supply is on the right track if:
If you are checking these boxes, you are doing an amazing job. Every body is different, and some parents naturally produce exactly what their baby needs without ever having an "extra" ounce to spare. That is perfectly normal.
It might seem unrelated to what you drink, but your stress levels have a massive impact on your milk flow. High levels of cortisol (the stress hormone) can interfere with oxytocin. Oxytocin is the hormone that triggers your let-down reflex.
If you are stressed and dehydrated, it’s a double whammy for your supply. This is why many cultural traditions emphasize warm, comforting drinks and plenty of rest for new parents. When you sit down with a warm cup of barley water or a cold Milky Mama drink, take a deep breath. Lowering your shoulders and relaxing your jaw can actually help your milk flow more easily.

No, drinking a lot of water will not typically decrease your supply, but "flooding" your system with plain water without enough electrolytes can sometimes make you feel more depleted. It is better to drink to your thirst and include some electrolyte-rich options rather than forcing yourself to drink excessive amounts of plain water.
Many parents notice a difference in how they feel—specifically their energy and thirst levels—almost immediately. However, for a noticeable increase in milk volume, it usually takes 48 to 72 hours of consistent hydration combined with frequent milk removal.
While sports drinks provide electrolytes and hydration, many are high in sugar and artificial colors. It is generally fine to have one a day if it helps you stay hydrated, but try to balance it with water, coconut water, or specialized lactation drinks that focus on more natural ingredients.
Caffeine itself isn't a "milk killer" in small amounts, but it can lead to dehydration if you aren't drinking enough water alongside it. Most lactation experts suggest limiting caffeine to 200-300mg per day (about 1-2 cups of coffee) to avoid issues with hydration or baby fussiness.
