Riboflavin :- Deficiency of riboflavin leads to ulcers on the tongue (red fiery tongue) known as glossitis or ulcers over the corners of the mouth and ulcers over the cornea with watering of eyes, intolerance to light and blurring of vision. If the pregnant woman is riboflavin deficient, growth and development of the baby is affected.

Riboflavin deficiency is rare as Vitamin B2 is present in milk, cheese, meat, eggs, fish, green leafy vegetables and whole grains. Diagnosis of riboflavin deficiency is made clinically and dramatic improvement is seen on supplementation with Vitamin B2.

Again, similar genetic disorders can occur due to deficiency of enzymes in the body and riboflavin supplementation in high dose can aid in its treatment.
