If I had another baby, I would definitely try it. I don't think I could do it myself though, I would need someone to do it for me. But I would take them due to the health benefits it's supposed to give new mummas.
With all of my pg and births, I have had Antenatal/ Postnatal depression, I have hemorrhaged after birth, requiring blood transfusions in two of my births and I was borderline with the other, and been fairly badly anaemic. So taking encpsulated palcenta would likely really help me, considering it worked as it should! And if not, it wouldn't hurt me!
