Vitamin B12 is a necessary water-soluble vitamin because it dissolves in water and leaves the body through the urine. Like the opposite B vitamins, vitamin B12 is essential for the nervous system’s maintenance, red blood cell formation, and protein metabolism. Due to this fact, having a vitamin B12 deficiency can negatively impact health.

The human body does produce Vitamin B12. Nevertheless, the method isn’t very effective. The specialised bacteria that produce vitamin B12 in humans grow within the lower a part of the digestive system.

The beneficial each day allowance (RDA) rises to 2.6 micrograms while pregnant and a couple of.8 micrograms per day during nursing. Currently, there are not any known harmful effects of vitamin B12. That’s since the body can eliminate any extra water-soluble vitamins through urination.
