B12 is an essential vitamin that you can become deficient in, particularly if you follow a restricted or special diet (such as vegetarian or vegan), if you’re pregnant or breastfeeding, older adults, those who have had gastrointestinal surgery or suffer from gastrointestinal illnesses, and people with an autoimmune condition known as pernicious anaemia. if you suffer from certain health conditions or if you are over a certain age.
Heavy smokers and drinkers can also have low levels of B12.
