The single most effective way to increase milk production is to remove milk from your breasts more often and more completely. Your body operates on a supply-and-demand system: the more milk that leaves, the more your body makes. Beyond that core principle, nutrition, rest, skin-to-skin contact, and certain supplements can all play supporting roles.
How Your Body Decides How Much Milk to Make
Two hormones drive the process. Prolactin stimulates your breast tissue to grow and actually synthesize milk. Oxytocin triggers what’s called the let-down reflex, contracting tiny muscles around the milk-producing cells to push milk through the ducts and out through the nipple. Suckling (or pumping) sends signals to your brain to release both hormones, which is why frequent feeding is the foundation of everything else.
There’s also a built-in regulator inside the breast itself. Your milk contains a protein called FIL (feedback inhibitor of lactation) that slows production when milk sits in the breast too long. The fuller your breast stays, the more FIL accumulates and the stronger the “slow down” signal becomes. When you empty the breast, FIL is removed and production speeds back up. This mechanism works independently in each breast, which is why skipping feeds or going long stretches between sessions can quietly reduce your supply over days and weeks.
Frequent, Thorough Milk Removal
Because of the FIL system, the most reliable way to increase supply is to nurse or pump more often and to drain the breast as fully as possible each time. For most people, that means at least 8 to 12 feeding or pumping sessions in 24 hours during the early weeks. If your baby isn’t latching well or feeding effectively, a lactation consultant can help you troubleshoot positioning. Poor latch is one of the most common hidden causes of low supply because it means milk isn’t being removed efficiently, even though you’re spending plenty of time at the breast.
If you’re pumping, try adding two or three extra sessions per day. One practical approach: pump as normal for about 20 minutes, turn off the pump and massage your breasts for 10 minutes, then pump again. This mimics the way a baby cluster-feeds in the evening and can help signal your body to ramp up production. Many people see results within a few days, though it can take a week or more of consistent effort.
Skin-to-Skin Contact
Holding your baby against your bare chest boosts oxytocin levels, which supports the let-down reflex and helps milk flow more easily. This effect is strongest in the first hour after birth, when both mother and baby are in a hormonally primed state, but it remains useful well beyond the newborn period. Skin-to-skin time also tends to encourage more frequent nursing because your baby can smell the milk and will often root and latch on their own. Even outside of feeding times, holding your baby chest-to-chest for 20 to 30 minutes can help if you’re struggling with let-down.
Calories, Iodine, and Choline
Making milk takes energy. The CDC recommends an additional 330 to 400 calories per day compared to what you were eating before pregnancy. You don’t need to count precisely, but consistently undereating, whether from dieting, stress, or simply forgetting meals, can drag your supply down. Prioritize calorie-dense, nutrient-rich foods when you can.
Two micronutrients deserve special attention during lactation. Iodine needs increase, with a recommended intake of 290 micrograms per day. Dairy products, eggs, seafood, and iodized salt are good sources. Choline requirements also rise to 550 milligrams per day. Eggs are one of the richest sources (one large egg has about 150 mg), along with meat, fish, and cruciferous vegetables like broccoli. Most prenatal vitamins don’t contain enough of either nutrient, so it’s worth checking labels.
Hydration: What the Evidence Actually Shows
You’ve probably heard that you need to drink massive amounts of water to keep your supply up. The research tells a different story. Multiple studies, including a Cochrane review of the available evidence, found that drinking extra fluids beyond what you need to satisfy thirst does not increase milk production. One randomized study found no significant relationship between supplemental fluid intake and milk output, even over a prolonged period.
That doesn’t mean hydration is irrelevant. Dehydration can make you feel terrible and may modestly reduce output. The practical advice: drink to thirst, keep a water bottle nearby while nursing, and don’t force yourself to chug water in hopes of boosting supply. If your urine is pale yellow, you’re likely fine.
Herbal Galactagogues
Fenugreek is the most studied herbal option. A network meta-analysis of four clinical trials found that fenugreek significantly increased breast milk volume compared to placebo. The effect was modest but real, and fenugreek is widely available as capsules or tea. Common side effects include a maple-syrup smell in your sweat and urine, and it can cause digestive upset in some people. It may also lower blood sugar, so use caution if you have diabetes or are on blood sugar medications.
Moringa leaf has gained popularity as an alternative. In a double-blind trial, mothers taking 900 mg per day of moringa leaf powder produced 47% more milk by day three postpartum than the placebo group. However, that difference was not statistically significant due to small sample sizes, and the actual volume difference was modest (about 73 mL versus 50 mL). Some earlier studies with preterm mothers showed more promising results. A review article noted that 500 mg per day of moringa has been associated with increased breast milk, but the overall evidence is still limited.
Neither fenugreek nor moringa is a substitute for frequent milk removal. They work best, if they work, alongside the behavioral strategies above.
Prescription Medications
Some doctors prescribe medications that raise prolactin levels as a side effect. The most commonly studied is metoclopramide, typically used for 7 to 14 days. However, the results are underwhelming. In one study, the treated group pumped only about 20 mL per day more than the placebo group, a difference researchers themselves questioned the clinical importance of. A meta-analysis of eight trials found that while the drug raised prolactin levels, it did not meaningfully increase milk supply. Well-designed studies concluded that once nursing technique has been optimized, the medication provided no additional benefit.
These drugs also carry side effects, including fatigue, mood changes, and in rare cases more serious neurological effects. They’re generally considered a last resort, and only after all non-pharmaceutical approaches have been tried.
Stress, Sleep, and the Bigger Picture
Stress directly interferes with oxytocin release, which can suppress the let-down reflex even when your body is producing plenty of milk. If you notice your let-down is slower or weaker during anxious moments, that’s the mechanism at work. Deep breathing, a warm compress on the breast before feeding, or simply nursing in a calm, comfortable spot can help.
Sleep deprivation compounds the problem. Prolactin levels are naturally highest during nighttime and early morning hours, which is one reason nighttime feeds are particularly effective for maintaining supply. Skipping night feeds entirely in the early weeks may seem tempting but can reduce the hormonal signals your body relies on. If you need to stretch one interval for rest, try to keep at least one session between midnight and early morning.
Low supply has many possible causes, from latch issues and infrequent feeding to hormonal conditions like thyroid dysfunction or insufficient glandular tissue. If you’ve consistently nursed or pumped 8 or more times per day, addressed latch, eaten enough, and still see low output after a week or two, that’s worth investigating with a healthcare provider who specializes in lactation.
