Wondering which foods actually help increase breast milk supply—and which are just wishful thinking? You're in the right place. For the complete picture on breastfeeding nutrition, see our complete guide for Australian mothers—but right now, let's focus on what the evidence says about specific foods.

It's the middle of the night. Your baby is cluster feeding again, and despite your best efforts, you're worried your supply isn't keeping up. So you do what every exhausted mother does—you grab your phone and search "foods to increase milk supply."

The results are overwhelming. Oats. Fenugreek. Brewer's yeast. Fennel. Garlic. Cookies that promise miracles. Everyone has an opinion, and half of them contradict each other.

Here's what you actually need: a clear, evidence-based review of which foods may genuinely support lactation, which are probably overhyped, and what matters most when you're trying to nourish both yourself and your baby.

Before we dive into specific foods, let's be honest about something important: no food is a magic solution for low milk supply.

The Australian Breastfeeding Association is clear that the most effective way to increase supply is frequent, effective milk removal—whether through breastfeeding or pumping. Food plays a supporting role, not a starring one.

That said, nutrition genuinely matters. Breastfeeding requires an additional 300-500 calories daily, and your body needs adequate protein, healthy fats, and hydration to produce quality milk. Certain foods—called galactagogues—have traditional or emerging evidence suggesting they may support lactation.

The key word is "support." If you're experiencing genuinely low supply, food alone won't fix underlying issues like ineffective latch, hormonal imbalances, or insufficient glandular tissue. For a deeper look at why some mothers struggle despite doing everything right, see our article on the real reasons behind milk supply challenges.

You'll find brewer's yeast listed in the AI snippets and nearly every lactation cookie recipe. It's rich in B vitamins, iron, and protein—all nutrients that support lactation.

However, there's a significant catch that most resources don't mention: brewer's yeast causes digestive issues in many mothers and can contribute to unsettled, gassy babies.

Most brands use it as their primary galactagogue because it's inexpensive, not because it's the most effective or best-tolerated option. If you've tried lactation cookies before and they upset your stomach or made your baby fussy, brewer's yeast was likely the culprit.

This is exactly why Nella Vosk's Nourish Mama range is formulated without brewer's yeast—we focus on gentler galactagogues like oats, flaxseed, and fennel that support lactation without the common side effects.

For more on what makes lactation foods genuinely helpful (versus just marketed well), see our article on are lactation cookies actually healthy.

While specific galactagogues get all the attention, two basics matter more than any superfood:

Hydration

Breast milk is approximately 87% water. If you're dehydrated, your body will prioritise your own hydration over milk production. Aim for roughly 13 cups (3 litres) of fluid daily while breastfeeding—more if you're active or in hot weather.

Plain water works, but many mothers find they drink more when it tastes good. Our Nourish Mama hydration drinks are designed specifically for breastfeeding mothers who need more than just water.

Adequate Calorie Intake

Breastfeeding burns 300-500 extra calories daily. Severe calorie restriction can impact supply. This isn't the time for restrictive dieting—it's the time for nutrient-dense eating that fuels both you and your baby.

When you're exhausted and barely have time to eat properly, convenience matters. Here are practical options:

Lactation cookies and snacks: Quality lactation cookies combine multiple galactagogues (oats, flaxseed, nuts) in a convenient, tasty format. Look for options without brewer's yeast if you or your baby have sensitive digestion.

Lactation bliss balls: A no-bake, grab-and-go option. Our Nourish Mama Lactation Bliss Balls are allergen-friendly and brewer's yeast-free.

Lactation beverages: Warm drinks can support hydration while delivering supportive herbs. Our Lactation Teas and Lactation Hot Chocolates offer convenient, comforting options.

Food can genuinely support your breastfeeding journey—but it works best as part of a comprehensive approach that includes frequent feeding, adequate rest, good hydration, and overall nutritious eating.

And remember: if you're doing everything right and still struggling with supply, the issue may not be your diet. Our article on why some mothers struggle despite their best efforts explores the underlying causes that food alone can't fix.
