Lactation is the process of synthesizing and secreting milk from the mammary glands, regulated by hormones like prolactin and oxytocin. Mothers who perceive a low milk supply often seek substances to increase production. These substances, known as galactagogues, can be pharmacological or non-pharmacological, such as herbs and dietary supplements. Supplements are typically considered after addressing other potential issues that affect milk output. This article explores the most commonly researched supplements used to support milk production.
Identifying Common Causes of Low Milk Supply
Before considering supplements, understand that low milk output is often related to insufficient milk removal rather than a physiological inability to produce milk. The principle of milk production is supply and demand: the more thoroughly and frequently the breast is emptied, the more milk the body is signaled to make. An ineffective latch or poor positioning can prevent complete drainage, leading to a reduced signal for production.
Infrequent feeding or pumping, especially in the early weeks, can cause a supply to drop because the necessary stimulation is missing. Certain maternal health conditions can interfere with the hormonal pathways required for lactation. Thyroid issues, diabetes, and conditions like Polycystic Ovary Syndrome (PCOS) can affect the hormonal signals that regulate milk synthesis.
Other factors that can suppress milk supply include the use of certain medications, such as hormonal birth control methods or decongestants. In rare cases, a retained placental fragment after birth can release hormones that inhibit lactation. Addressing these underlying issues, often with the guidance of a healthcare professional, is the most effective step in improving milk supply.
Key Herbal and Nutritional Galactagogues
Herbal galactagogues have been used across various cultures for centuries, though scientific evidence for many remains limited. These herbs are thought to support milk production by influencing the hormones involved in the process. When trying these options, mothers typically look for a noticeable increase in milk output within 24 to 72 hours.
Fenugreek is the most well-known herbal galactagogue and is a member of the pea family. While its precise mechanism is not fully clear, some theories suggest it may stimulate sweat production, which could indirectly affect milk output. A common side effect of consuming fenugreek is that the mother’s sweat, urine, and even the baby’s urine may take on a distinct maple syrup odor.
Blessed Thistle is frequently used alongside fenugreek, as a combination of the two herbs is often recommended. While limited human studies exist to confirm its direct efficacy, it is traditionally believed to aid in milk flow. Goat’s Rue may be helpful for mothers who did not experience significant breast growth during pregnancy or who have hormonal imbalances like PCOS. This herb is thought to stimulate the development of mammary tissue.
Beyond specific herbs, general nutritional supplements play a supportive role in maternal health, which in turn supports lactation. B vitamins are essential for energy metabolism and overall well-being. Continuing to take prenatal vitamins throughout the breastfeeding period helps ensure adequate stores of nutrients like B12. Adequate protein intake and overall hydration also provide the necessary building blocks and fluid volume for consistent milk synthesis.
Safe Use and Professional Guidance
Herbal supplements are classified as dietary supplements, meaning they are not subject to the same rigorous testing and regulation by the Food and Drug Administration (FDA) as prescription drugs. This lack of standardization means that the potency and purity can vary significantly between brands and batches. It is recommended to choose products from reputable manufacturers.
Before starting any new supplement regimen, consult with a healthcare provider or a board-certified lactation consultant (IBCLC). They can help rule out underlying medical causes for low supply and discuss potential drug interactions. Fenugreek and Goat’s Rue may lower blood sugar levels and should be used cautiously by mothers with diabetes or those taking blood thinners.
Mothers should start with a low dose and gradually increase the amount while monitoring for side effects like digestive upset. If a supplement does not produce a noticeable increase in milk supply within about a week, it should be discontinued. The most effective approach to increasing milk supply remains frequent and effective milk removal, with supplements acting only as additional support.
