Can kombucha affect the health of a baby during breastfeeding?

Kombucha While Breastfeeding - Is It Safe, or Should Moms Avoid It?

Kombucha is a fermented drink that enjoys great popularity due to its purported beneficial effects on digestion and the immune system. If you are a new mom considering whether kombucha is suitable while breastfeeding, it is important to understand its composition and potential impact on both your body and your baby. In this article, we will look at all the key aspects you should consider.

What is kombucha and why is it so popular?

Kombucha is a drink made by fermenting sweetened tea with the help of a symbiotic colony of bacteria and yeast (SCOBY). During fermentation, sugar is broken down into organic acids, enzymes, trace amounts of alcohol, and carbon dioxide, which gives the drink its mild fizziness.

What does kombucha contain?

• Probiotics – live bacteria that support a healthy gut flora.
• Organic acids – such as acetic acid and glucuronic acid, which can aid in detoxification.
• Antioxidants – derived from black or green tea, which help protect cells from oxidative stress.
• Caffeine – its amount depends on the type of tea used.
• Alcohol – a natural product of fermentation, usually in low amounts (around 0.5%).

Kombucha is therefore a complex drink that can be beneficial for some breastfeeding mothers, while posing certain risks for others.

Is kombucha safe while breastfeeding?

1. Alcohol content in kombucha and its effect on breast milk

One of the most common reasons why breastfeeding mothers are wary of drinking kombucha is its alcohol content. This is produced during fermentation, and although it is a very small amount, it is not negligible.

A complex factor is also that homemade kombucha may contain higher alcohol levels than commercially produced versions, which are strictly controlled. If you decide to drink kombucha while breastfeeding, it is advisable to choose a verified product with low alcohol content and start with a small amount.

Breast milk contains the same amount of alcohol as the mother’s blood. Therefore, if a woman drinks more kombucha with higher alcohol content, some of it can pass into the breast milk, potentially affecting the baby.

2. Caffeine in kombucha and its impact on infants

Kombucha is made from black or green tea, meaning it contains caffeine. The amount depends on the type of tea used and the fermentation duration.

• Black tea contains more caffeine and can have a stimulating effect.
• Green tea has less caffeine, which is more favorable for breastfeeding mothers.
• Herbal teas (such as rooibos) contain no caffeine and can be an ideal alternative.

For some babies, caffeine can cause restlessness, irritability, and sleep issues. If you notice your baby is sleeping poorly or is more irritable after you consume kombucha, it might be better to stop for a while and observe any changes.

3. Probiotics in kombucha

One of the main reasons people drink kombucha is for its probiotic effects. A healthy gut flora supports good digestion, a strong immune system, and overall well-being. Breastfeeding mothers may experience digestive issues after childbirth, such as constipation or bloating, and kombucha could be a natural aid.

On the other hand, fermented foods can be problematic for some sensitive individuals. If you have never tried kombucha before, it is better to start with a small amount (e.g., 100 ml per day) and monitor how you and your baby respond to it.

How to consume kombucha safely while breastfeeding?

If you decide to include kombucha in your diet while breastfeeding, it is recommended to follow several guidelines:

• Start with a small amount – for example, 100–150 ml per day, and monitor reactions.
• Buy quality and verified products – avoid homemade versions that may contain higher levels of alcohol.
• Prefer kombucha made from green tea – as it contains less caffeine than black tea.
• Avoid flavored kombucha containing herbs – some herbs (such as sage, mint) can negatively affect milk production.
• Be aware of the baby's reactions – if you notice changes in their behavior or digestion, try omitting kombucha for a few days.

With proper use, kombucha can be a beneficial drink even during breastfeeding. It is essential, however, to choose a quality product with low alcohol content, monitor the caffeine amount, and observe the reactions of both your body and your baby. Every woman reacts differently, and while some may find kombucha helpful for digestion and immunity, others may experience unwanted effects.

If you are unsure whether kombucha is suitable for you while breastfeeding, it is advisable to consult with a doctor or nutrition specialist. It is always better to be cautious and start with a smaller dose than to risk discomfort for both you and your baby.
