Vitamin B12 is essential for our health because it helps produce healthy red blood cells and supports DNA synthesis. We mainly get it from consuming animal products like meat, eggs, fish or dairy. An interesting fact: Hydrochloric acid (in our stomach) works together with proteins during digestion to make it available for the body’s use. Additionally, intrinsic factor -- a transport molecule produced by the parietal cells of the stomach—helps B12 get absorbed by cells lining the ileum section of the small intestine.
