Vitamin B12, an essential water-soluble vitamin, is very important for the production of red blood cells, synthesis of DNA, and normal neurological function. However, its absorption in the body is complex and depends on many factors. Many patients complain of persisting signs of vitamin B12 deficiency even after taking supplements regularly.
Thus, adequate absorption of vitamin B12 is very important in all individuals, especially at-risk groups such as vegetarians, vegans, elderly people, and others who have certain medical conditions.
