The `Mad Men` actress gave birth to son Xander last September and admits she has been dining on the ephemeral organ - which connects a baby to their mother while they are in the womb and delivered after the birth - in capsule form ever since.
When asked how she copes with being a working mother, January told People magazine: "I have a great doula who makes sure I`m eating well, with vitamins and teas, and with placenta capsulation.
"Your placenta gets dehydrated and made into vitamins. It`s something I was very hesitant about, but we`re the only mammals who don`t ingest our own placentas.
"It`s not witch-crafty or anything! I suggest it to all moms!"
January - who refuses to name Xander`s father - went back to work soon after her son`s birth but was grateful he was able to coem to teh `Mad men` set with her.
She said: "I think I went back to set six or seven weeks after, so he was really little. I had the baby and the baby nurse in their own room so I could go back and feed him every two hours.
"If I felt like he needed me, or if he needed to eat, or even if I just needed a squeeze because I was having separation issues, I would go back and see him. It was such a blessing that I wasn`t separated from him."
