How to Take Brewer's Yeast to Increase Milk Supply

The most effective way to take brewer’s yeast is to start with a small amount and gradually increase your intake. This allows your body to adjust to the supplement and helps you monitor any potential side effects.

Determining Your Dosage

There is no universal "standard" dose for brewer's yeast, as every body reacts differently. However, many lactation consultants and herbalists suggest a general range.

For Powder: A common starting point is 1 tablespoon per day. You can gradually work your way up to 2 or 3 tablespoons daily if you do not experience digestive upset.
For Tablets: Most tablets are 500mg. A typical recommendation is taking 2 to 3 tablets up to three times a day with meals. Always follow the specific instructions on the product label.

It is always a good idea to consult with a certified lactation consultant or your healthcare provider before starting any new supplement. They can help you determine the right amount based on your specific health history and milk supply goals, and our Breastfeeding Help page can connect you with additional support.

Timing Your Intake

Consistency is key when using any galactagogue. Most parents find it helpful to take brewer’s yeast at the same time every day. Splitting your daily dose into smaller portions throughout the day—such as at breakfast and dinner—may help with absorption and minimize any potential stomach discomfort.

What to do next:

Start with 1/2 or 1 tablespoon of powder daily.
Monitor your body’s reaction for 2–3 days.
Increase the dose slowly until you reach the desired amount (usually up to 3 tablespoons).
Check in with a professional if you have concerns about your supply.

Tasty Ways to Incorporate Brewer’s Yeast Powder

Since the taste of brewer's yeast can be an acquired one, many parents prefer to hide it in delicious recipes. Mixing the powder with strong flavors like chocolate, peanut butter, or fruit is a great way to make it more palatable.

Lactation Cookies and Brownies

One of the most popular ways to take brewer's yeast is by baking it into "lactation treats." Cookies and brownies are excellent because they usually include other milk-supporting ingredients like oats and flaxseed. The sweetness of the treat helps mask the nutty flavor of the yeast.

If you don't have the time or energy to bake from scratch, our Emergency Lactation Brownies are a favorite among many breastfeeding families. They are professionally formulated with brewer's yeast, oats, and flax to provide a convenient and tasty way to support your supply. If you want to explore more treat options, the Lactation Snacks collection is a helpful next stop.

Smoothies and Shakes

Adding a tablespoon of brewer's yeast to your morning smoothie is a quick way to get your daily dose. It pairs especially well with:

Frozen bananas
Nut butters (almond or peanut)
Cocoa powder
Greek yogurt or plant-based milk

The creamy texture of a smoothie helps the powder blend in thoroughly, so you don't have to deal with a gritty texture. You can also browse the Lactation Smoothies collection for more inspiration.

Oatmeal and Hot Cereals

Oats are another fantastic food for lactation. Stirring a teaspoon or two of brewer's yeast into a warm bowl of oatmeal is a double-win for your milk supply. You can top it with honey, cinnamon, and berries to enhance the flavor profile. If you want a deeper dive into that ingredient, read Which Oats Are Good for Breastfeeding & Milk Supply?.

Key Takeaway: You can easily mask the bitter taste of brewer’s yeast by mixing it into smoothies, oatmeal, or baked goods like cookies and brownies.

Understanding Potential Side Effects

While brewer's yeast is generally considered safe for most people, it can cause some mild side effects. Because it is a type of yeast, it can lead to increased gas and bloating in both the parent and the baby. If you notice your little one seems unusually fussy or gassy after you start taking it, you may want to reduce your dose.

Some people also report experiencing "yeast headaches" when they first start supplementation. This is often why we recommend starting with a very small dose and increasing it slowly over a week or more.

Important Medical Considerations

There are specific situations where brewer’s yeast may not be appropriate. You should exercise caution or avoid brewer’s yeast if you fall into any of the following categories:

Diabetes: Brewer's yeast contains chromium, which can lower blood sugar. This can be dangerous if you are already taking medication for diabetes or are prone to hypoglycemia.
Yeast Allergies: If you have a known allergy to any type of yeast, you should avoid this supplement.
Crohn’s Disease: Some studies suggest that brewer’s yeast can trigger flare-ups in people with Crohn’s disease.
Weakened Immune System: People with compromised immune systems should consult a doctor, as there is a very small risk of fungal infections from certain types of yeast supplements.
MAOI Medications: If you are taking Monoamine Oxidase Inhibitors (MAOIs) for depression, brewer’s yeast can cause a dangerous spike in blood pressure due to its tyramine content.

Maximizing Your Results: More Than Just Supplements

While taking brewer’s yeast can be a wonderful supportive tool, it is not a "magic pill." Milk production is primarily a system of supply and demand. To see a significant increase in your supply, you must ensure that milk is being removed from the breast frequently and effectively.

The Power of Frequent Milk Removal

The more your baby nurses or the more you pump, the more your body is told to produce. If you are using brewer’s yeast, make sure you are also:

Nursing on demand (whenever your baby shows hunger cues).
Ensuring a deep, comfortable latch to effectively drain the breast.
Adding a pumping session after nursing if you are trying to build a stash or increase demand.
Practicing skin-to-skin contact, which releases oxytocin and helps with milk let-down.

If you are focusing on pumping, our How to Increase Milk Supply While Pumping Exclusively guide can help you build on these habits.

Hydration and Nutrition

Your body needs plenty of fluids and calories to make milk. Drinking water to thirst is essential. You might also consider supportive beverages from our Lactation Drink Mixes, which are designed to keep you hydrated while providing lactation-supportive ingredients. A well-nourished parent is much more likely to have a healthy milk supply.

When to See a Professional

If you have tried brewer’s yeast and other lifestyle changes but are still concerned about your baby’s weight gain or the number of wet diapers, it is time to reach out for professional help. A Certified Lactation Consultant (IBCLC) can evaluate your baby's latch, check for tongue ties, and help you create a personalized plan to reach your breastfeeding goals.

Remember, you are doing an amazing job. Breastfeeding can be challenging, but you do not have to do it alone. Whether you choose to use supplements or not, your dedication to your baby's nutrition is something to be proud of.

Conclusion

Brewer's yeast is a versatile, nutrient-rich option for parents looking to support their lactation journey. By providing essential B vitamins, minerals, and protein, it can help bridge the gap in your postpartum nutrition while potentially offering a boost to your milk supply. Whether you prefer to take it as a convenient tablet or bake it into a delicious treat, the key is consistency and monitoring how your body responds.

Start with a low dose (1 tablespoon or a few tablets) and increase slowly.
Incorporate it into flavorful foods like smoothies or baked goods to mask the bitterness.
Prioritize frequent milk removal through nursing or pumping for the best results.
Consult your doctor if you have underlying health conditions like diabetes or Crohn's.

Key Takeaway: Brewer’s yeast works best as part of a holistic approach that includes proper hydration, frequent nursing, and self-care.

FAQ

How long does it take for brewer's yeast to increase milk supply?

Many parents report seeing a difference within 24 to 72 hours of consistent use. However, every body is different, and for some, it may take a week or more to notice a change. It is important to continue frequent milk removal during this time to see the best results.

Does brewer's yeast make babies gassy?

It is possible for brewer's yeast to cause gas or bloating in both the parent and the baby. If you notice your baby is more fussy or gassy than usual after you start taking it, try reducing your dosage. If the issue persists, you may want to consult with a lactation consultant to explore other options.

Is brewer's yeast the same as nutritional yeast?

No, they are not exactly the same, although they come from the same species of yeast. Brewer's yeast is a by-product of beer brewing and has a much more bitter flavor. Nutritional yeast is grown specifically for consumption and has a cheesy, savory flavor, though both are rich in B vitamins.

Can I take brewer's yeast if I am taking other lactation supplements?

In many cases, brewer's yeast can be combined with other herbs or supplements. However, because some supplements contain multiple ingredients, you should check for any overlaps or potential interactions. Always consult with your healthcare provider or a lactation professional before mixing different herbal remedies.
