Vitamin B12 is a water-soluble vitamin, which is very important for animals

The risk is particularly high among those aged 65 years and older and those with chronic conditions such as diabetes, with mortality rate increasing with age

For example, pernicious anemia is one of the most common causes of vitamin B12 deficiency because it is an autoimmune disease where the immune system attacks specialized stomach cells that produce intrinsic factor (a protein that binds to B12 for absorption)

These injections are administered directly into the hip muscle for increased absorption

Green poop may also be a sign of an infection, especially if it is also accompanied by diarrhea , fever, abdominal cramps, or bloody stools
