When it comes to the nerves and nervous system, B12 is needed for the production of myelin sheath
Fish, meat, poultry, and eggs are all rich in B12, while dairy products also contain large amounts of B12
For most people, yes, when it is medically appropriate and supervised
well thank you, well yes so one the second day or any days within the six days then our b12 is still working on our bodies, I feel it working still the next day but I wansn't sure if it was symptoms felt because i'm out already or it is just healing symptoms the day after an injection
However, a measured oral bioavailability percentage in a living animal has not been published, so orally bioavailable is a reasonable expectation rather than an established fact
