Absolutely love these vitamins! I started during my first trimester, and have been using daily for over 1 year now. My son was born 7lbs 12oz and 21in long, at 38 weeks. My labor and delivery team as well as my son's pediatrician couldn't believe he was so big for only being 38 weeks, and made repeated comments that he looked like a full term 40 week baby. While I most definitely attribute this to a healthy lifestyle, I must also give hearty credit to Root'd because I believe it really gave my son an advantage in the womb. Highly, highly recommend this product.
