Are cranberry supplements safe to ingest while pregnant?

Why supplements? Supplements are often not regulated by anyone. If pregnant, i would stick to whole food nutrition, with the exception that Folic Acid is important to lower the risk of a neural tube defect like spina bifida. Look around for those types of products to keep you and your baby healthy.
Yes. Yes. Try using cranberries in your cooking too. Remember always try to use the unprocessed whole ingredient rather than a pill/supplement.
