I have asked my midwife, my doula, my doctor, I have googled, wikipedia'ed and read scientific papers, yet still have no idea where my (or any) nhs healthcare trust get's it's vitamin k and what source it is derived from. Does anyone know? I only take supplements for myself if I know they are derived from natural sources. I would find the decision whether to allow my baby to receive vitamin k (whether orally or via injection) an awful lot easier if I knew who supplies the nhs and how they produce their vitiman k for newborns. Hoping someone can enlighten me.......
