Insurance coverage for Vitamin B12 injections can differ depending on your individual plan

User reports are mixed on this point
If tiredness is caused by poor sleep, stress, anaemia from another cause, thyroid problems, depression or another condition, B12 may not solve it
This process is inherently inefficient
