It is generally advised to avoid drinking non-alcoholic beer during pregnancy because it can contain trace amounts of alcohol, usually up to 0.5% ABV. No safe level of alcohol consumption has been established for fetal development, and even minute amounts might pose some risk, so health organizations recommend complete abstinence from alcohol, including non-alcoholic beer, to protect the baby. Pregnant women should consult their healthcare provider for personalized advice and consider safer alternatives like alcohol-free mocktails, herbal teas, or fruit juices.
