I have updated the Research & Articles section of the PlacentaBenefits.info website. I’ve added some interesting articles under Scientific Research that explore the link between iron deficiency and fatigue, iron deficiency and postpartum depression, and fatigue and postpartum depression. It is not a hard leap to then assume that since placenta capsules are (presumably) loaded with iron, that the capsules would then help restore depleted iron levels, which would then help alleviate symptoms of fatigue, and could therefore perhaps even stave off postpartum depression. Please read the three new articles yourself and see if you come to the same logical conclusion.
There are more articles added to the Health & Wellness and Placenta Articles headings, so check those out as well. The placenta is an amazing organ!
