11. Helps Prevent Auto-Immune Diseases
Auto-immune diseases, examples of which are Multiple Sclerosis, Crohn’s disease, fibromyalgia and endometriosis, are becoming more common every year. Auto-immune diseases are caused when the body’s immune system mistakenly identifies normal cells a foreign and starts attacking them. Researchers have linked a deficiency of Vitamin B12 to many of these diseases. Because Vitamin B12 is essential for the health of the membrane surrounding each cell, and for the accurate replication of cells, it is thought that a deficiency can result in some cells being incorrectly labelled by the immune system as invasive and therefore needing to be destroyed.
