ANSWER: There is limited research on the safety of D-mannose during pregnancy. It is a naturally-occurring sugar that is found in small quantities in fruits such as cranberries and blueberries, so it is generally considered to be safe when consumed in small amounts.
While D-mannose is a natural supplement, it is still a type of sugar that can be absorbed by the body and may affect blood sugar levels. High blood sugar levels during pregnancy can increase the risk of complications, such as gestational diabetes, preterm birth, and other adverse outcomes.
Additionally, some sources suggest that D-mannose may have a mild diuretic effect, which can increase urine output and potentially affect fluid balance during pregnancy. This could be particularly concerning for women who are at risk of dehydration or other fluid imbalances.
Although there is limited research on the safety of D-mannose during pregnancy, some healthcare providers may recommend it as a natural alternative to antibiotics for preventing and treating UTIs, which are more common during pregnancy. However, it is important to follow recommended dosages and to seek medical attention if symptoms persist or worsen.
In summary, pregnant women should exercise caution when considering the use of D-mannose and should discuss its use with a healthcare provider before taking it as a supplement.
However, it is always important to consult with your healthcare provider before taking any supplements during pregnancy to ensure they are safe for you and your baby. Your provider can help you determine the appropriate dosage and can also monitor for any potential side effects or interactions with other medications you may be taking.
