Royal jelly

Hannah • Mummy to a beautiful 10year old boy and wife to an amazing husband. Currently trying for our first baby together.
Has anyone ever tried Royal jelly?!?! My friend is swearing by the stuff saying she fell pregnant the month she started using it after trying for months!! 
I read up on it and it's meant to be really good for your health and for trying to conceive but just wondered if anyone else has good success with it too x
