Apple Cider Vinegar and Breastfeeding
The risks of taking apple cider vinegar and breastfeeding at the same time are unknown because no research has been done on the topic. Although a small amount of pasteurized apple cider vinegar used for cooking does not likely pose any risk, women who are breastfeeding should avoid apple cider vinegar supplements or unpasteurized apple cider vinegar products.
It is not known if apple cider vinegar is safe for use in women who are breastfeeding. Because there may be unknown risks, you should check with your healthcare provider before taking apple cider vinegar if you are nursing a child.
No research has been done to see if apple cider vinegar passes through breast milk or if it is safe for women who are breastfeeding (or their infants). Using a small amount of pasteurized apple cider vinegar in cooking probably does not pose any risk. However, apple cider vinegar supplements or unpasteurized apple cider vinegar products should be avoided when breastfeeding. Because the benefits of apple cider vinegar have never been proven (and because the risks are unknown), the potential risks of using it outweigh the possible benefits, especially for women who are breastfeeding.
You should talk with your healthcare provider about apple cider vinegar and breastfeeding. Each woman's situation is different, and you and your healthcare provider understand your situation best. After considering what you want and expect, as well as your current health situation, the two of you can make a shared decision about apple cider vinegar and breastfeeding that is right for you.
