It felt like someone turned the lights back on. So, what is B12 really and why are so many people lacking it
Dietary sources of B12, such as meat, fish, and dairy products, provide most people with enough of the vitamin
Both unborn and newborn babies have a special need for vitamin B12 and if the mother is a vegetarian or a vegan, this need may not be met either through her diet for the unborn or through her breast milk for the newborn

Many people start with injections to quickly restore levels and then switch to oral supplements for maintenance
