Vitamin B2 (Riboflavin)
Along with vitamin A, riboflavin helps give good vision and promotes growth. It naturally occurs in milk, where it is the yellow pigment.
While it's not destroyed by cooking, it is by strong light, so milk should always be stored away from such sources.
Deficiencies show up as anaemia, cracked lips, tongue inflammations, a sensation of sand in the eyes, cataracts, migraine - and if prolonged, heart disease.
As well as milk, brewer's yeast, leafy green vegetables, fish and eggs are good sources. The Recommended Daily Allowance is 1.7mg for adults and 1 mg for children. Since the vitamin is excreted through the kidneys, excessive consumption will result in yellowish/green urine, but this is perfectly normal.
