Peppermint is a popular flavor during the festive Christmas season, and it's often found in candies, teas, and other treats. While peppermint is generally considered safe for consumption, there is a traditional belief that it may have an impact on milk supply.

Some people claim that peppermint, particularly in the form of peppermint tea, might potentially decrease milk supply. However, scientific evidence is limited and has yet to support this as true. A 2020 study found that Menthol did suppress milk production in mice. Menthol is a chemical naturally found in peppermint and other mint plants, but it can also be made in a lab. It's essential to note that individual responses can vary, and not every breastfeeder will experience a noticeable effect on milk supply when consuming peppermint.

If you're breastfeeding, enjoy your peppermint mocha during the holiday season. Pay attention to your body's response, and if you have concerns about your milk supply, consult with an IBCLC lactation consultant for personalized advice.

I believe the REAL reason why we see supply drop at the holidays isn’t the peppermint consumption, but being off normal schedules and routines, traveling, and having the baby be passed from grandma to aunt to friend where hunger cues are being missed and feedings delayed. In general, maintaining a well-balanced diet, staying hydrated, and responding to your baby's feeding cues are crucial factors in supporting a healthy breast milk supply. Enjoying holiday treats in moderation, including those with peppermint.
