Lactation cookies, whether you bake a batch yourself or buy them, some breastfeeding mothers have turned to them to optimize their milk supply. 

Not that we're ones to bad-mouth cookies, but we've asked the experts and, there isn’t much science to back this up. If you’re feeding your baby breastmilk, supply will be on your mind whether you are breastfeeding or using expressed milk from a breast pump.

Paediatric and pregnancy dietitian and owner of, Hannah Whitaker tells us, “The combination of [certain] ingredients is said to increase milk supply when consumed regularly. There is no evidence base for these claims.” Mom-of-one Casey sampled lactation cookies when breastfeeding her daughter; “I was very conscious of maintaining my milk supply because I was exclusively pumping. A family friend who had breastfed recommended lactation cookies. I bought them from Amazon then switched to Etsy.”

Breastfeeding can be a hard slog for many moms, with Kiran, mom-of-one telling us; "For something that's 'so natural' it did not 'come naturally' it was a lot of learning, wiggling about and feeling my way around. I managed to breastfeed for 9 months and was constantly scared of getting mastitis and was so nervous about stopping breastfeeding - but it worked out fine in the end and I'm glad I persevered." 

 What are the ingredients in lactation cookies? 

Typically, a lactation cookie contains brewer’s yeast, flaxseed, oatmeal, the herb fenugreek, and possibly nuts and dried fruit. 

Nutritionally speaking, experts are dismissive of the claims that lactation cookies can help with milk supply. The School of Public Health at the University of Indiana recently published a study that found no evidence that consuming lactation cookies improves milk supply. The research also found that relying on lactation cookies can prompt false hope in mothers. Expert paediatric and pregnancy dietitian and owner of Hannah Whitaker agrees, “There is no evidence base for these claims.” In addition, a La Leche League spokesperson also told us, “Over the years there have been many myths relating to breastfeeding. At present, there is no research that proves that eating specific baked goods will increase milk production.”

 When to start using lactation cookies 

If you are going to sample cookies, there are guidelines about when to start. Hannah explains: “Manufacturers advise starting to use them is after your baby has been born and you have established breastfeeding – usually around two weeks postpartum. However, as a dietitian, this is not something that I would recommend.” 

Instead, as Hannah tells us, “Consuming a well-balanced diet, including all food groups – balanced carbohydrates, proteins, unsaturated fat and fruit and vegetables is essential when breastfeeding.”

Rhiannon Lambert is a registered nutritionist, author, and host of the Food For Thought podcast.

Rhiannon adds, “If you’re concerned about your milk supply, it’s always best to speak with a lactation expert to see if you need to adjust your diet and lifestyle to help support your milk coming in. There’s no harm in eating lactation cookies as part of a balanced diet. They can be a great source of energy and fibre but know that they are not essential and are not necessary for milk production."

How many lactation cookies should I eat? 

Cookie manufacturers suggest starting with two cookies per day. However, eating too many lactation cookies is not advised.

Hannah explains, “Lactation cookies should not be consumed with the aim to increase breastmilk supply. If the homemade cookies contain nutritionally balanced ingredients, then they can be a balanced snack containing omega 3 and fibre. But, just like any other snack, if eaten multiple times per day this can lead to excessive calories or high consumption of certain ingredients such as brewer's yeast and flaxseed, which is high in fibre and could affect the bowels.”

Casey can’t be sure if the lactation cookies she ate did help her milk supply: “It’s hard to say if they affected my supply, I was trying all sorts: alcohol-free beer – I read the yeast helps; drinking loads of water to stay hydrated, breastfeeding vitamins and dried fruit bars with fenugreek. I experienced both over-supply and under-supply – there didn't really seem to be any rhyme or reason.”

Cook’s tips

Once baked, you can tightly seal these cookies and freeze them for up to 3 months. Alternatively, freeze the batter before cooking for up to 3 months. Roll the batter into a sausage shape and tightly seal. When ready to bake, heat the oven and slice the cookies into disks, then put them into the oven. They may take a few mins longer but they will be just as delicious.

- If the batter is sticky, dampen your hands and roll the cookie into balls, or add a tbsp more flour.

- If you don’t have brown sugar, you can use golden caster sugar as an easy alternative.

- Feel free to add more nuts or seeds to make these cookies even tastier, you could use milk or white chocolate too, instead of dark.
