12 Best and Worst Foods for Boosting Your Breast Milk Supply | Lactation Nutrition Tips

With positive energy and open hearts, we start.

Parenting is a long journey of learning and growth. Breastfeeding is a wonderful way to bond with your baby while providing essential nutrients for their growth and development. For many moms, concerns about milk supply can arise, and diet plays a crucial role in maintaining healthy lactation. 

Some foods can help increase breast milk production, while others may hinder it. In this article, we’ll explore 12 of the best and worst foods for boosting your breast milk supply.

6 Best Foods for Boosting Breast Milk Supply

1. Oats

Oats are a popular food among breastfeeding moms due to their high iron content. Low iron levels can reduce milk production, and incorporating oats into your diet can help combat this. Oats are also rich in fiber and help regulate digestion, which is beneficial for new moms.

How to eat them: Enjoy a bowl of oatmeal in the morning or add oats to smoothies and baked goods.

2. Fenugreek Seeds

Fenugreek is one of the most well-known herbs for boosting milk supply. It contains phytoestrogens, which can help increase milk production. Many moms see results after taking fenugreek supplements or drinking fenugreek tea.

How to use it: Fenugreek seeds can be added to dishes, or you can drink fenugreek tea up to three times a day.

3. Fennel Seeds

Fennel seeds contain compounds that mimic estrogen, helping to increase milk supply. Fennel is also great for digestion, making it a helpful remedy for both mom and baby in reducing colic or gassiness.

How to use it: Add fennel seeds to your meals, or steep them in hot water to make fennel tea.

4. Brewer’s Yeast

Brewer’s yeast is a common ingredient in lactation cookies and is packed with B vitamins, iron, protein, and chromium, which all support healthy milk production. It’s also great for boosting your energy levels as a new mom.

How to use it: Add brewer’s yeast to smoothies, soups, or baked goods to get its lactation-boosting benefits.

5. Leafy Green Vegetables

Leafy greens like spinach, kale, and alfalfa are rich in phytoestrogens and iron, both of which can support breast milk production. These greens are also nutrient-dense, providing essential vitamins for both you and your baby.

How to eat them: Add leafy greens to salads, smoothies, or stir-fries to reap their benefits.

6. Garlic

Garlic is a lactogenic food that can help increase milk production. While it may slightly alter the taste of breast milk, many babies actually enjoy the flavor, and it can stimulate longer feeding sessions.

How to use it: Add garlic to soups, stir-fries, or roasted vegetables to boost your milk supply.

6 Worst Foods for Breast Milk Supply

1. Sage

Sage is known to reduce milk supply, making it one of the foods to avoid if you're trying to increase production. It contains natural compounds that can suppress lactation, which is why it’s often recommended for moms looking to wean.

How to avoid it: Limit dishes that contain sage, such as certain poultry seasonings or teas.

2. Peppermint

While peppermint tea is soothing, it can also reduce breast milk production if consumed in large quantities. Like sage, peppermint is often used when moms are ready to stop breastfeeding.

How to avoid it: Be cautious with peppermint-flavored products like tea, gum, or candy if you’re trying to maintain a good milk supply.

3. Parsley

Parsley is another herb that can reduce breast milk supply when consumed in excess. It’s a diuretic, meaning it can reduce fluid levels in your body, which is important for milk production.

How to avoid it: Use parsley sparingly in your meals if you're concerned about your milk supply.

4. Alcohol

Excessive alcohol consumption can significantly reduce your milk supply and interfere with the let-down reflex. Occasional moderate drinking is generally considered safe for breastfeeding, but heavy drinking should be avoided.

How to manage: Limit alcohol intake and allow at least 2 hours per drink before breastfeeding.

5. Caffeine

While moderate caffeine consumption is generally safe, too much caffeine can lead to dehydration and interfere with milk production. It can also make your baby fussy or irritable if too much passes through breast milk.

How to manage: Stick to one or two cups of coffee or tea per day and drink plenty of water to stay hydrated.

6. Strong Mint Teas

Mint teas, including spearmint and peppermint, can have a drying effect on milk supply if consumed in large quantities. While a cup or two is unlikely to harm milk production, large amounts can reduce supply over time.

How to avoid it: Limit your intake of mint teas if you're concerned about your milk supply.

Supporting your breast milk supply through mindful food choices is one of the simplest and most natural ways to nourish both yourself and your baby. While every body is different — and milk supply can change for many reasons — choosing foods that gently support lactation can make the journey feel smoother and more empowering.

Remember: feeding your baby is not just nutrition — it’s connection, comfort, and care. However you choose to nourish your little one, what matters most is that you feel supported, informed, and confident in your choices.
