Breastmilk Colors

breastmilk colors

Breastmilk is a unique and complex fluid produced by the mammary glands of lactating women. It is widely recognized as the ideal source of nutrition for infants, providing them with essential nutrients and antibodies that promote their growth and development. And breastmilk colors are sometimes not affected on breastmilk storage.

However, breastmilk is not always a uniform shade of white or yellow. In fact, it can vary in color, ranging from clear to yellow, green, blue, or even pink. This variation in breastmilk colors has intrigued researchers and healthcare professionals, leading to a growing body of literature exploring the factors that influence these color changes.

Factors Influencing Breastmilk Colors


Various factors can influence the colors observed in breastmilk, creating a diverse range of shades that can include hues of yellow, white, blue, green, brown, or even pink.

One of the primary factors that can affect breastmilk color is the mother’s diet. Certain foods and beverages consumed by the mother can pass through her breastmilk and alter its color. For example, consuming foods rich in carotenoids, such as carrots or sweet potatoes, can give breastmilk a yellowish hue. Similarly, consuming foods or drinks containing dyes, like blueberries or beetroot, may result in breastmilk that appears blue or pink.


Another factor that can influence breastmilk color is the mother’s medication intake. Some medications can pass into breastmilk and cause changes in its color.

For instance, certain antibiotics or iron supplements can give breastmilk a greenish tint.

Additionally, herbal remedies or supplements that the mother may be taking can also affect breastmilk color.


It is important for breastfeeding mothers to consult with their healthcare providers to ensure the safety of any medications or supplements they are taking, as well as to understand the potential impact on breastmilk color.

Breastmilk colors can vary greatly due to various factors. The mother’s diet and medication intake play significant roles in determining the shades observed in breastmilk.

By understanding these factors, healthcare providers and breastfeeding mothers can better comprehend the range of colors that breastmilk can exhibit, ensuring the health and well-being of both the mother and the nursing child.

The Role of Diet in Breastmilk Color

Different maternal dietary factors have been studied to understand their influence on the pigmentation of human milk.

One such factor is the consumption of carotenoid-rich foods. Carotenoids are natural pigments found in fruits and vegetables, such as carrots, tomatoes, and leafy greens.

Research suggests that when lactating women consume a diet rich in carotenoids, their breastmilk may take on a slightly yellow or orange hue. This is because carotenoids are absorbed by the body and can be transferred to breastmilk.

However, it is important to note that the concentration and color of carotenoids in breastmilk can vary depending on individual differences in absorption and metabolism.

In addition to carotenoids, the consumption of certain spices and herbs has also been linked to changes in breastmilk color. For example, the consumption of fenugreek, which is commonly used as a galactagogue to promote milk production, has been reported to cause a sweet, maple syrup-like odor and a yellowish color in breastmilk. Similarly, the consumption of beetroot or beet juice can sometimes lead to a pink or reddish tinge in breastmilk.

These changes in breastmilk color due to dietary factors are usually harmless and do not affect the nutritional composition or quality of the milk. However, it is always advisable for lactating women to consult with a healthcare professional or a lactation consultant if they have concerns about the color of their breastmilk or any other aspect of their breastfeeding journey.

Health Conditions and Breastmilk Color Variations

Health conditions can lead to variations in the color of breastmilk, highlighting the complex relationship between physiological factors and the composition of this vital source of nutrition for infants.


One health condition that can impact breastmilk color is mastitis, which is an infection of the breast tissue. Mastitis can cause breastmilk to appear darker in color, often taking on a yellow or greenish hue. This change in color is due to the presence of white blood cells in the milk, which are mobilized by the body’s immune response to fight off the infection.

While the presence of white blood cells in breastmilk is not harmful to infants, it is important for breastfeeding mothers to seek treatment for mastitis to prevent further complications.


Another health condition that can affect breastmilk color is jaundice, which is a condition characterized by the yellowing of the skin and eyes due to high levels of bilirubin in the blood. In some cases, breastmilk from mothers with jaundice may also take on a yellowish color. This is because bilirubin can be excreted in breastmilk, leading to a temporary change in its appearance.

It is important for breastfeeding mothers with jaundice to consult with healthcare professionals to ensure proper management of the condition and to monitor the health of their infants.

Debunking Common Misconceptions about Breastmilk Colors

One common misconception is that breastmilk should always be white in color. In reality, breastmilk can vary in color, ranging from clear to yellow to even bluish-green. The color of breastmilk can be influenced by various factors such as the mother’s diet, medications she may be taking, and the stage of lactation.

Another misconception is that the color of breastmilk is an indicator of its nutritional value. While it is true that breastmilk composition changes over time to meet the nutritional needs of the growing infant, the color of breastmilk alone does not determine its nutritional content.

The nutritional value of breastmilk is primarily determined by its composition of fats, proteins, carbohydrates, vitamins, and minerals. These components are not visually apparent and cannot be assessed by simply looking at the color of breastmilk.

Therefore, it is important not to make assumptions about the nutritional value of breastmilk based solely on its color.

Frequently Asked Questions

Can breastmilk color change throughout the day?

Yes, breastmilk color can change throughout the day. Factors such as a mother’s diet, hydration levels, and the stage of lactation can influence the color. It is normal for breastmilk to range from clear to white, yellow, or even greenish.

The time it takes for breastmilk color to return to normal after consuming certain foods varies. Factors such as the type and amount of food consumed, as well as individual differences in metabolism, can influence the duration of color change.

Breastmilk color is not a reliable indicator of whether a baby is getting enough nutrients. Other factors such as weight gain, growth patterns, and overall health should be considered to assess a baby’s nutritional status.

A greenish tint in breastmilk can be considered normal and is generally not a cause for concern. It may be due to the presence of certain enzymes or changes in the mother’s diet. Further evaluation by a healthcare professional may be necessary if other symptoms are present.

Stress or emotional changes can potentially affect the color of breastmilk. However, further research is needed to establish a definitive link. Previous studies suggest that stress hormones may alter the composition of breastmilk, potentially leading to changes in color.


The color of breastmilk is influenced by the foods and beverages consumed by the mother, with certain foods like beets and carrots leading to a reddish tint in the milk. Similarly, medications taken by the mother can also affect the color of breastmilk, resulting in changes ranging from green to blue.

Additionally, certain health conditions such as mastitis or infections can cause breastmilk to appear pink or brownish.

It is important to note that while changes in breastmilk color can be concerning, they are usually harmless and do not affect the quality or nutritional value of the milk.

It is normal for breastmilk to vary in color, and these variations are typically temporary and resolve on their own.

It is crucial for breastfeeding mothers to be aware of the factors that can influence breastmilk color and to seek medical advice if they notice any persistent or unusual changes.

By understanding the factors influencing breastmilk colors, mothers can feel reassured that these variations are normal and continue to provide their babies with the valuable benefits of breastfeeding.
