eating placenta??

sm
Hello mamas! 
I’m pregnant with my first baby and I’ve been really interested in learning about placenta encapsulation & eating the placenta in pill form after birth to prevent postpartum depression. 
Any mamas who have tried this can you tell me your experience? Did it help you? I’ve also heard it can make you more emotional & effect milk supply so i would love to hear first hand experiences.... was it what you expected?? 
Thanks for your input!
