Galactagogues are substances—herbal, food-based, or pharmaceutical—that are believed to support breast milk production. They are widely discussed in breastfeeding communities, and many lactating people report subjective improvements when using them. However, the scientific evidence supporting their effectiveness and safety is limited and mixed, and they should not be viewed as a primary solution for low milk supply.
What Are Galactagogues?
Galactagogues include:
Herbal or food-based substances (e.g., fenugreek, moringa, brewer’s yeast, lactation teas)
Pharmaceutical agents sometimes used off-label (e.g., domperidone, metoclopramide)
Pharmaceutical galactagogues have been evaluated more rigorously in clinical studies, with some evidence showing modest short-term increases in milk volume for specific medications like domperidone when used under medical supervision. Evidence for most herbal or food-based galactagogues is inconclusive or low certainty, with inconsistent results across studies.
Why Evidence Matters
A systematic review and analyses of clinical trials found that both pharmaceutical and natural galactagogues lack strong, high-quality evidence showing consistent benefits for increasing breast milk production. Many available studies are small, vary in design, and do not adequately report safety outcomes. Healthcare providers face challenges recommending galactagogues with confidence due to this limited evidence base.
Potential Safety Concerns
Herbal and dietary galactagogues are widely available as supplements but are not regulated by the U.S. Food and Drug Administration (FDA) for safety, effectiveness, or consistency of ingredients.
As a result:
Dosage levels, purity, and product quality can vary significantly.
Some herbal substances may interact with medications or affect underlying health conditions.
Safety profiles for many agents have not been adequately studied in lactating people or infants.
For example:
Fenugreek may impact blood sugar regulation and is not recommended for people with diabetes or hypoglycemia without clinical oversight.
Herbal supplements may also interact with thyroid function, clotting processes, or other medical conditions.
Clinical Context and Lactation Management
Before considering any galactagogue, it is important to focus on foundational strategies that support milk supply based on lactation physiology, including:
Ensuring effective infant latch and positioning
Frequent, comfortable breastfeeding or pumping to promote milk removal
Addressing infant factors that may affect milk transfer
Evaluating maternal health conditions that may influence supply (e.g., hormonal imbalances, metabolic factors)
Clinical practice guidelines emphasize that galactagogues should not be used as first-line interventions for low milk supply. A comprehensive assessment by a qualified lactation clinician or healthcare provider should precede any supplemental approaches.
When Galactagogues May Be Considered
In select clinical situations—particularly after optimizing feeding mechanics and evaluating underlying causes—providers may discuss galactagogues as part of a broader lactation plan. Decisions about their use should be individualized and guided by a healthcare provider who can assess potential benefits, risks, interactions with medications, and personal health history.
Summary
Galactagogues are widely used but supported by limited and mixed evidence regarding effectiveness.
Safety data are often incomplete, particularly for herbal products.
Prioritizing standard lactation support measures and clinical assessment is essential before considering galactagogues.
Any use of these substances should be discussed with a qualified provider to ensure appropriate evaluation and monitoring

Frequently Asked Questions
Can galactagogues cause side effects?
Yes. Depending on the substance, side effects may include gastrointestinal upset, changes in blood sugar, allergic reactions, or interactions with medications. Some galactagogues may worsen certain medical conditions, such as diabetes or thyroid disorders.
Should galactagogues be used as a first-line treatment for low milk supply?
No. Clinical guidelines recommend addressing breastfeeding or pumping technique, milk removal frequency, infant feeding effectiveness, and underlying medical conditions before considering galactagogues. Supplements should not replace comprehensive lactation evaluation.
When might a galactagogue be considered?
In select cases, a healthcare provider may discuss galactagogues after a thorough lactation assessment and medical evaluation. Use should be individualized, time-limited, and monitored for effectiveness and side effects.
Are prescription galactagogues more effective than herbal ones?
Prescription galactagogues have been studied more extensively than herbal supplements, but benefits are generally modest and not universal. These medications carry potential risks and should only be used under medical supervision.
Can galactagogues help if there is an underlying medical cause of low milk supply?
Galactagogues are unlikely to be effective as a sole intervention if an underlying medical or hormonal condition is not addressed. Identifying and managing factors such as endocrine disorders, metabolic conditions, or prior breast surgery is essential for appropriate treatment planning.
Should I talk to a healthcare provider before using a galactagogue?
Yes. Because galactagogues may interact with medications or medical conditions, it is important to consult a healthcare provider experienced in lactation before starting any supplement or medication.
