Definition
Riboflavin, also known as vitamin B 2, is a water-soluble vitamin, one of the B vitamins. In biosynthesis, the flavin portion of the molecule is combined with a ribose-like part derived from ribulose 5-phosphate to become riboflavin.
Functions
Riboflavin is essential to the formation of two major coenzymes, flavin mononucleotide (FMN, also called riboflavin-5’-phosphate) and flavin adenine dinucleotide (FAD). FMN and FAD are involved in energy metabolism, cell respiration, antibody production, growth and development.
Synthesis
The biosynthetic precursors to riboflavin are ribulose 5-phosphate and guanosine triphosphate. The former is converted to L-3,4-dihydroxy-2-butanone-4-phosphate while the latter is transformed in a series of reactions that lead to 5-amino-6- (D-ribitylamino)uracil.
Chemical properties
Riboflavin is a yellow-orange crystalline powder having a slight odor and bitter taste. It is soluble in polar solvents, such as water and aqueous sodium chloride solutions, and slightly soluble in alcohols. It is not soluble in non-polar or weakly polar organic [lipid]] solvents such as chloroform, benzene or acetone.
Medical uses
Corneal ectasia is a progressive thinning of the cornea; the most common form of this condition is keratoconus. Corneal collagen crosslinking, causing an increase in corneal stiffness, is achieved by applying a riboflavin solution topically, then exposing to ultraviolet A light.
Food coloring
Riboflavin is used as a food coloring (yellow-orange crystalline powder), and is designated with the E number, E101, in Europe for use as a food additive.
Dietary recommendations
In humans, there is no evidence for riboflavin toxicity produced by excessive intakes. Absorption becomes less efficient as doses increase, and what is absorbed in excess of requirements is excreted via the kidneys into urine, resulting in a bright yellow color known as flavinuria.
9 Pharmacology and Biochemistry
Riboflavin or vitamin B2 is an easily absorbed, water -soluble micronutrient with a key role in maintaining human health. Like the other B vitamins, it supports energy production by aiding in the metabolising of fats, carbohydrates, and proteins.

Vitamin B2 and Health
Because riboflavin assists many enzymes with various daily functions throughout the body, a deficiency can lead to health problems. Animal studies show that the brain and heart disorders and some cancers can develop from long-term riboflavin deficiency.
Food Sources
Riboflavin is found mostly in meat and fortified foods but also in some nuts and green vegetables.
Signs of Deficiency and Toxicity
A riboflavin deficiency is very rare in the United States. Disorders of the thyroid can increase the risk of a deficiency. A riboflavin deficiency most often occurs with other nutrient deficiencies, such as in those who are malnourished. Symptoms may include:
Did You Know?
Ever wonder why you don’t usually see milk stored in glass bottles anymore? The reason is due to riboflavin. If the vitamin is exposed to too much light, it can be deactivated from its usable form. Therefore milk is now typically sold in cartons or opaque plastic containers to block light.

Riboflavin Sources
Foods containing riboflavin include avocados, dried roasted almonds, boiled asparagus, turkey breast, minced beef, whole-grain bread, sweet potatoes, swiss chard, and eggs. It is also found in yeast extracts, beans, pork, boiled mushrooms, peas, spinach, pasta, etc.
Riboflavin Supplements
Riboflavin is also available as a supplement, usually prepared along with B-complex vitamins or in multivitamin supplements.
Riboflavin Benefits
A very positive aspect of riboflavin is its ability to reduce the number and severity of migraines in people who often suffer from them. Studies show that this is because people with migraines have low levels of cellular energy in their brains. Riboflavin helps cells make better use of energy, which helps prevent migraines.
Side Effects
Riboflavin has the potential for side effects and interactions. The dietary supplement should therefore be taken under the strict supervision of an experienced healthcare professional. Although generally considered safe, high doses above 10 grams per day can damage the eyes due to the sun.
Deficiencies of riboflavin
Unlike thiamine, riboflavin is stored in the kidneys and liver. Therefore, riboflavin deficiency can last for three or four months. Most people consume a lot of riboflavin, so deficiencies are rare. People who exercise a lot, people with diabetes, the elderly, and vegetarians need extra riboflavin.
Riboflavin deficiency symptoms
Riboflavin deficiency causes nausea, dizziness, dermatitis, hair loss, sensitivity to light, insomnia, slow growth, indigestion, burning sensation in the legs, and slow mental reactions. It can also cause eye disorders, skin lesions, inflammation of the tongue and mouth, and cracks and ulcers in the corners of the mouth.
Riboflavin functions
Due to its yellow-orange color, riboflavin is commonly used as a dye in many foods. It is also used to enrich various foods such as breakfast cereals, sauces, pasta, fruit juices, baby food, processed cheeses, dairy products enriched with vitamins, and energy drinks.
Description
Riboflavin is a water soluble vitamin produced by plants and many micro-organisms. Humans cannot produce riboflavin even though it is essential to life. Insufficient riboflavin (called Ariboflavinosis) can result in loss of hair, inflammation of the skin, vision deterioration, and growth failure.
Common Uses
Riboflavin can be difficult to incorporate into most foods due to poor solubility and because it degrades quickly when exposed to sunlight.
E Number
There are actually two types of riboflavin used as colouring agent. The E Numbers are 101 and 106.
Notes
I have not been able to find any product that lists riboflavin as an ingredient specifically added to provide colour. It is hard, because Canada does not require product labels to specifically state what kind of food colouring is used. If anybody knows of such a product (in any country) please leave a comment.

Signs of Deficiency and Toxicity
More than 90% of riboflavin in the diet is in the form of protein-bound FMN and FAD. Exposure to gastric acid in the stomach releases the coenzymes, which are subsequently enzymatically hydrolyzed in the proximal small intestine to release free riboflavin.
