No single food is guaranteed to increase your milk supply, but several foods and herbs have traditional and emerging scientific support as galactagogues, substances that promote breast milk production. The most important factor is eating enough overall calories, staying well hydrated, and nursing or pumping frequently. That said, adding specific nutrient-dense foods to your diet can support the hormonal and energy demands of lactation.
What the Research Actually Shows
A large Cochrane review examined 27 studies on natural galactagogues, including fenugreek, moringa, ginger, fennel, palm dates, banana flower, and various herbal teas. Thirteen of those studies measured milk volume directly. The subgroup analyses suggested either a benefit or no meaningful difference for most of these foods, but the overall certainty of the evidence was rated very low. That doesn’t mean these foods don’t work. It means the studies were small, measured things differently, and can’t be pooled together for a clear answer.
Moringa and mixed botanical teas showed the most promising signals for increasing infant weight gain, which is an indirect marker of milk intake. Fenugreek and fennel had less consistent results. So while the science is still catching up to centuries of traditional use, there’s enough signal to make several of these foods worth trying, especially since most carry minimal risk.
Foods and Herbs Worth Adding
Oats
Oats are one of the most commonly recommended lactation foods, and while formal clinical trials are limited, the nutritional profile makes sense. Oats are rich in iron, fiber, and complex carbohydrates, all of which support the sustained energy demands of milk production. Many lactation consultants consider them a first-line dietary addition. A bowl of oatmeal at breakfast or oat-based snacks throughout the day is the simplest way to incorporate them.
Fenugreek
Fenugreek is probably the most studied herbal galactagogue. In one clinical trial, mothers who consumed 7.5 grams of fenugreek soaked overnight in water, taken once daily for seven days, saw improvements in infant urination frequency and weight gain during the first week of life. No negative side effects were reported in either mothers or infants. You can find fenugreek as whole seeds, capsules, or tea. One common side effect to know about: it can make your sweat and urine smell like maple syrup, which is harmless but surprising.
Moringa
Moringa leaves showed some of the more encouraging results in clinical research, particularly for infant weight gain. Moringa is extremely nutrient-dense, packed with iron, calcium, and vitamins A and C. It’s commonly consumed as a powder stirred into smoothies, soups, or water. In the Philippines and parts of Africa, moringa soup is a traditional postpartum food for exactly this reason.
Ginger
Ginger has a long history as a galactagogue across Asian cultures. Research on papaya and ginger combinations suggests ginger functions as a galactagogue, and it appeared in multiple studies reviewed by Cochrane. Fresh ginger in cooking, ginger tea, or ginger added to soups are all practical options. It also helps with nausea, which some new parents still experience postpartum.
Fennel
Fennel seeds and fennel tea are traditional galactagogues in Mediterranean and Middle Eastern cultures. The Cochrane review included fennel among the studied interventions, though results on infant weight were uncertain. Fennel has a mild licorice flavor and works well brewed as tea or added to salads and roasted vegetables.
Palm Dates
Dates appeared in the Cochrane review as a natural galactagogue and are a staple postpartum food in many Middle Eastern traditions. They’re calorie-dense and rich in natural sugars, potassium, and fiber, making them a practical snack for breastfeeding parents who need quick energy between feeds.
Brewer’s Yeast
Brewer’s yeast is a common ingredient in lactation cookies and smoothies. It’s an excellent source of iron, protein, and B vitamins, all nutrients that support energy levels during breastfeeding. The direct evidence for milk supply is anecdotal rather than clinical, but the nutritional density alone makes it a useful addition. You can find it as a powder or in tablet form.
The Role of Overall Nutrition
Your body needs significant extra energy to produce milk. Breastfeeding burns roughly 300 to 500 additional calories per day, and consistently under-eating is one of the most common and overlooked causes of low supply. This isn’t the time to restrict calories. Focus on regular meals and snacks built around whole grains, lean proteins, healthy fats, fruits, and vegetables.
Protein is especially important because it provides the building blocks for milk synthesis. Eggs, chicken, fish, beans, lentils, nuts, and dairy are all solid choices. Omega-3 fats from fatty fish like salmon, sardines, or from walnuts and chia seeds support both your health and your baby’s brain development through milk. The CDC specifically notes that breastfeeding parents eating vegetarian or vegan diets should pay attention to iron, vitamin B12, and omega-3 intake, and may need supplements for those nutrients.
Hydration Matters, but Not the Way You Think
You’ve probably heard “drink more water” as the go-to advice for milk supply. The relationship is real but nuanced. In a study where lactating women were restricted from all fluids for over 14 hours and lost an average of 7.6% of their body weight from dehydration, their milk production was not affected in the short term. Your body prioritizes milk synthesis even when you’re mildly dehydrated, pulling water from other systems to do it.
That said, chronic under-hydration makes you feel terrible and can eventually affect supply. A practical approach: drink enough that your urine stays pale yellow. Keep a water bottle wherever you usually nurse or pump. Many parents find they’re suddenly thirsty the moment a feeding starts, so having water within reach helps. You don’t need to force massive quantities; just drink to thirst and add a glass or two extra if your urine looks dark.
Foods That Can Decrease Supply
While you’re thinking about what to add, it’s worth knowing what to limit. A few herbs and foods can work against milk production if consumed in large quantities:
- Peppermint and spearmint: An occasional cup of peppermint tea is fine, but eating large amounts of peppermint oil candies daily has been linked to noticeable drops in supply.
- Sage: Sage tea is actually used as a remedy for oversupply, so avoid large amounts if your supply is already low.
- Parsley: Small amounts in cooking are fine, but parsley-heavy dishes like tabbouleh are worth limiting in the early postpartum weeks.
- Alcohol: Alcohol inhibits your letdown reflex, making it harder for your baby to extract milk. Over time, this can reduce supply.
- Cabbage leaves: Applying cabbage leaves to the breasts more than once or twice a day, a common remedy for engorgement, can decrease production. Topical creams made from cabbage extract can have the same effect.
What Matters Most
The strongest driver of milk supply isn’t any single food. It’s frequent, effective milk removal. Your body produces milk on a supply-and-demand basis: the more milk that leaves your breasts, the more your body makes. Nursing or pumping at least 8 to 12 times in 24 hours during the early weeks establishes your baseline supply. No amount of fenugreek or oatmeal will compensate for infrequent feeding or a poor latch.
That said, layering galactagogue foods on top of frequent feeding, adequate calories, and good hydration gives your body the best raw materials to work with. Start with the basics: eat enough, drink enough, and feed often. Then add oats, fenugreek, moringa, or whatever galactagogues appeal to you. Many parents notice changes within a few days, though individual responses vary widely.
