Vitamin B12 is the only vitamin that must be obtained from animal foods or a multivitamin. It plays a vital role in the formation of red blood cells, nervous system health, cell metabolism and DNA production. Food sources of this vitamin include meat, poultry, fish and dairy products. A deficiency can lead to anemia, fatigue, muscle weakness, digestive problems and nerve damage. Vegetarians or vegans may be more at risk of vitamin B12 deficiency, as this vitamin is not found in plant foods.
