There was plenty of research to support the use of the supplements recommended along with general lifestyle changes that can cross over to just living a healthy lifestyle. They were reasonable , knowing that some of the items they recommend are highly priced, but than came back to note that if you can't, than go with option B. All for the greater good of a healthy mom and baby. Much appreciate this info from someone over 35 with a fee hormonal imbalances that may be helped by some of these recommendations along with a holistic health practitioner. Thank you!!
