From the Research
Vitex (chaste tree) can potentially pass into breast milk, and its use during breastfeeding is not well established, so it's generally recommended to avoid using vitex supplements unless specifically advised by your healthcare provider. The active compounds in vitex affect hormone levels, particularly prolactin, which is directly involved in milk production 1. This herb is traditionally used to regulate menstrual cycles and hormone balance, but these same hormone-modifying properties raise concerns about its use during lactation. Since vitex may alter prolactin levels, it could theoretically affect milk supply, though some herbalists suggest it might increase milk production in certain circumstances.
Some key points to consider when evaluating the use of vitex during breastfeeding include:
- The lack of clinical studies specifically examining the safety and efficacy of vitex during lactation 2, 3, 4, 5
- The potential for vitex to affect hormone levels, including prolactin, which could impact milk production 1
- The variability in response to vitex therapy depending on the underlying condition being treated, as seen in studies examining its use for menstrual cycle disorders 1
Given the limited research and potential risks, it is recommended that breastfeeding women consult with their healthcare provider before using vitex supplements. The provider can help weigh the potential benefits against the unknown risks and make an informed decision about the use of vitex during breastfeeding. Additionally, the safety profile of vitex during breastfeeding has not been well established through clinical studies, and more research is needed to fully understand its effects on lactation and infant health 1.
