Riboflavin is also called Vitamin B2. Milk products supply about half of the riboflavin that people get and unlike other vitamins, riboflavin is not destroyed by cooking. Vegetarians may have riboflavin deficiencies.
Children who do not get enough riboflavin may have poor growth. Vitamin supplements usually reverse symptoms within days to a few weeks.
Riboflavin deficiencies symptoms can include:
Dry and scaly skin, cracks at the corners of the mouth, eye disorders, swollen tongue or gums
