Background on vitamin B-2

Riboflavin (vitamin B-2) was originally recognized as a growth factor in 1879 and named vitamin B-2 according to the British nomenclature system.

Here’s what we know today.

  • Flavin adenine dinucleotide (FAD).
• Dietary sources include milk, eggs, meats, yogurt, broccoli, almonds, cheese, soy, fortified grains, and dark green vegetables, in descending order of concentration.
• Bacteria in the colon also synthesize riboflavin.
• Riboflavin or its coenzymes contributes to cellular growth, enzyme function, energy production, and carbohydrate, fat, and amino acid synthesis.
