Problems often develop because certain people's bodies have problems absorbing enough Vitamin B-12. People over 50 years of age, people who are otherwise prone to anemia, people who have had gastrointestinal surgeries (weight loss) or who have celiac disease or Crohn's disease. Some vegetarians and vegans don't get enough B-12 because they don't eat animal foods. Pregnant women and women who breastfeed their babies often don't get enough Vitamin B-12.
Studies show that Vitamin B-12 does not cause any harm. Benefits shown by B-12 consumption include assisting the body to convert food into energy, helps maintain a healthy nervous system, helps with cardiovascular health and is essential for red blood cell formation.
