Vit. B12 is a nutrient that is needed to make red blood cells (they carry oxygen in the body) and carry out nerve function.

Meat eaters get their vit. B12 from animals. The bacteria found in the animal's intestines contains the vitamin which is then consumed by humans.  

Symptoms of B-12 deficiency include:

Tiredness, weakness, constipation, loss of appetite, weight loss, and megaloblastic anemia. Nerve problems, such as numbness and tingling in the hands and feet, can also occur. Other symptoms of vitamin B12 deficiency include problems with balance, depression, confusion, dementia, poor memory, and soreness of the mouth or tongue. Vitamin B12 deficiency can damage the nervous system even in people who don’t have anemia, so it is important to treat a deficiency as soon as possible.
