Do Lactation Cookies Really Work? An Honest, Evidence‑Based Look

Lactation cookies have become a bit of a postpartum celebrity. Colourful packets, comforting flavours, and big promises about boosting milk supply. And honestly? When you’re exhausted, hungry, and trying to keep a tiny human fed, the idea of a cookie that helps feels pretty appealing.

But do they actually work?

Let’s break down what we know, what we don’t, and why the answer is more nuanced (and kinder) than a simple yes or no.

What Lactation Cookies Usually Contain

Most lactation cookies include a combination of:

• Oats - thought to support oxytocin release and provide iron
• Brewer’s yeast - rich in B vitamins and minerals
• Flaxseed - a source of omega‑3s and phytoestrogens
• Fenugreek/Fennel (sometimes) - a traditional galactagogue, though not suitable for everyone
• Healthy fats - butter, coconut oil, nut butters
• Sugar - because… they’re cookies

These ingredients are often labelled as “milk‑boosting,” but the evidence behind them is mixed.

What the Evidence Actually Says

Here’s the calm, honest truth: There’s very limited scientific evidence that lactation cookies increase milk supply.

Some ingredients (like oats or flaxseed) are nutritious and may support your overall wellbeing - which indirectly supports lactation. Others, like brewer’s yeast or fenugreek, have been used traditionally but don’t have strong clinical research behind them.

But that doesn’t mean parents who swear by them are “wrong.” Far from it.

Anecdotal Experience Matters Too

Across cultures, parents have used certain foods for generations to support postpartum recovery and lactation. That lived experience is valuable.

And then there’s the placebo effect, which is not a trick or a failure. It’s a well‑documented physiological response. Studies show placebo can be effective in up to 40% of cases, depending on the context.

If a cookie makes you feel cared for, nourished, hopeful, or more relaxed… that can absolutely influence your hormones and feeding experience.

Your brain and body are connected. That’s not fluff, that’s physiology.

So… Do Lactation Cookies Work?

They can, but not for the reasons the marketing suggests.

If you enjoy them, and they fit your budget, go for it. If they make you feel good, that’s a benefit in itself. If they give you a moment of nourishment in a chaotic day, that matters.

But they’re not a magic fix for low supply, and they shouldn’t be the only strategy you rely on.

What’s More Likely to Help Your Supply

If you’re genuinely trying to increase milk production, these strategies have far stronger evidence behind them:

• Frequent, effective milk removal (baby or pump)
• Optimising latch and positioning
• Checking milk transfer
• Offering both sides
• Skin‑to‑skin contact
• Reducing long gaps between feeds
• Ensuring your flange size is correct if pumping
• Looking after your own basic needs - eating, drinking, resting where possible

These are the things that shift supply in a meaningful, physiological way.

Why Eating Regularly Helps More Than Any “Milk Booster”

Many parents unintentionally under‑eat in the early weeks. You’re tired, overstimulated, and constantly feeding - it’s easy to forget yourself.

Lactation cookies often “work” simply because:

• You’re finally eating something
• They’re calorie‑dense
• They stabilise your blood sugar
• They give you a moment of comfort

Your body makes milk from your blood supply, not from special ingredients. So regular meals, snacks, and hydration matter far more than any single food.

When to Reach Out for Support

If you’re worried about supply, or if feeding feels painful, confusing, or inconsistent, personalised support can make a world of difference.

Most supply concerns are adjustable with the right information - and you don’t need to navigate that alone.

I offer warm, evidence‑based lactation support tailored to your baby, your body, and your feeding goals. A quick assessment can help you understand what’s actually happening and give you a clear, calm plan.

The Bottom Line

Lactation cookies aren’t harmful, and they can be a lovely treat. If you enjoy them and can comfortably afford them, absolutely go for it.

Just remember: Your supply is shaped far more by milk removal, latch, and support than by any cookie. And if you’re feeling unsure, overwhelmed, or stuck, you deserve guidance that’s grounded in evidence and centred on you.
