Vitamin B12 is a remarkable “helper” that plays important chemical roles in our cells. In your body, vitamin B12 is needed in the synthesis of DNA and, thus, is essential for the health of your blood and bone marrow, as well as maintenance of your nervous system, including your brain, spinal cord, and peripheral nerves. Chronic, severe deficiency of vitamin B12 can lead to anemia, dementia, paralysis, and death. As a result, maintaining adequate levels of vitamin B12 in your tissues is vital to your well being.
The statistics show that an overwhelming majority of people worldwide simply don’t get enough B12, and most adults over 50 according to studies but I think even adults over the age of let’s say 25 or 30 have problems absorbing B12.
