Riboflavin

Alternative names:

deficiency - vitamin B2 (riboflavin); diet and riboflavin; vitamin B2; vitamin B2 (riboflavin) deficiency

Side effects:

Deficiency of riboflavin is not common in the U.S. because this vitamin is plentiful in the food supply. Deficiency symptoms include dry and cracked skin and eyes that are sensitive to bright light.

There is no known toxicity to riboflavin. Because riboflavin is a water-soluble vitamin, excess amounts are excreted.
