health and life

Vitamin B12 is considered an essential nutrient and vital for cell division, the synthesis of red blood cells, and the functioning of the nervous system. It is also a necessary and vital nutrient for the process of methylation. 

Without intrinsic factor, produced in the stomach, we can’t absorb or utilize vitamin B12. A deficiency of vitamin B12 can affect every system of the body and give rise to anemia, lack of energy, and poor memory and concentration. 

Join Phyllis as she discusses the ins-and-outs of vitamin B12, its role in methylation, and foods, herbs, and supplements that may be useful in restoring or utilizing this vital nutrient.
