Vitamin B2

Deficiency of riboflavin is not common in the United States because this vitamin is plentiful in the food supply. Symptoms of a severe deficiency include:

• Anemia
• Mouth or lip sores
• Skin disorders
• Sore throat
• Swelling of mucus membranes

Because riboflavin is a water-soluble vitamin, leftover amounts leave the body through the urine. There is no known poisoning from riboflavin.
