A serious deficiency can be corrected in two ways, including weekly shots of vitamin B12 or daily high-dose B12 pills.
A mild B12 deficiency can be corrected with standard multivitamin supplements, which typically delivers 6 micrograms of B12 – more than the average body needs daily.
As with most conditions, early detection of a B12 deficiency is key. When it is left untreated it can lead to an onslaught of complications, including neurological problems and blood diseases.
Signs of severe B12 deficiency may also include depression, paranoia, delusions, memory loss, incontinence, loss of taste and smell and more.
