Do Lactation Cookies Really Work? What the Science Says

Lactation cookies have become a go-to snack for breastfeeding mothers, but do they actually increase milk supply? While these cookies often contain galactagogues (ingredients thought to support lactation), scientific evidence remains inconclusive. Let’s break down the facts.

What’s in Lactation Cookies?

Lactation cookies are packed with ingredients that are traditionally linked to supporting milk production:

Oats – A great source of iron, which may help mothers with low iron levels maintain milk supply.

Flaxseeds – Rich in omega-3 fatty acids that support hormonal balance.

Brewer’s Yeast – Contains B vitamins and minerals that may support lactation.

Fenugreek – A well-known herbal galactagogue, but research on its effectiveness is mixed.

What Does the Science Say?

There is no strong clinical evidence proving that lactation cookies directly increase breast milk supply. However:

Some studies suggest that galactagogues like fenugreek and brewer’s yeast may help some mothers, but results vary.

Proper nutrition and hydration play a crucial role in milk supply. Lactation cookies may help by providing extra calories and key nutrients.

The placebo effect may contribute—if a mother believes the cookies will help, she may feel more confident and relaxed, which can improve milk letdown.

The Bottom Line

Breast milk supply is primarily driven by supply and demand. Regular breastfeeding or expressing, proper hydration, and maternal health are the most important factors. Take a look at our full collection of breastfeeding essentials.

While lactation cookies aren’t a scientifically proven solution, they can be a nutritious and convenient snack. If milk supply is a concern, consulting a lactation consultant is the best evidence-based approach.
