B 2

Deficiency

 Severe B 2

deficiency or ariboflavinosis is very rare 

in developed countries.  The metabolism of B 2 is closely related to that of  several other B‐vitamins so the signs are almost  always from multiple deficiencies.  Common symptoms may include cracked and red  lips, inflammation of the lining of mouth and  tongue, mouth ulcers, cracks at the corners of the  mouth, and a sore throat.

B 2 in Food  There are many good dietary sources  of vitamin B 2 including most animal  products, milk and other dairy foods.  As with B 1 the USDA Nutrient  Database lists fortified breakfast  cereals as a very good concentrated  source of B 2 .
