Why Is B12 So Essential?
Vitamin B12 is the most important nutrient because it most importantly helps produce red blood cells. Blood plays a vital role in our lives, and without B12 to keep producing red blood cells we would have no blood. Therefore none of our body would function!
Dr. Bruce Bistrian, a chief of clinical nutrition at Harvard-affiliated Beth Israel Deaconess Medical Center, says that if a vitamin B12 deficiency is left untreated that it can cause severe blood diseases and neurologic problems.
