Also known as B2, riboflavin was the second B vitamin discovered. In its purest form it is a yellow-orange, water soluble compound. It is part of a two coenzyme known as Flavin adenine dinucleotide (FAD) and Flavin mononucleotide (FMN), which are essential for tissue respiration and the generation of energy from the metabolism. Supplementation of this vitamin can help reduce the frequency or severity of migraines as well.
Riboflavin is essential for tissue respiration and the generation of energy from the metabolism of carbohydrates, amino acids and fats. It is vital for the normal production, growth, repair and development of body tissues including skin, hair, nails and the immune system.
Brain and Nerve Function
In order for nerves to properly develop and for brain neurotransmitters to metabolize, riboflavin is required.
Blood cells use riboflavin for development and to metabolize iron.
Hormones and Glands
The adrenal glands cannot function without riboflavin and various hormones need riboflavin in order to be produced and regulated.
The flavocoenzymes play a role in oxidation-reduction reactions (redox reactions) which are processes that transfer electrons and create energy. Metabolism of carbohydrates, fats, and proteins create this energy.
- Up to 6 months old: 0.3 milligrams per day (mg/day)
- 7-12 months old: 0.4 mg/day
These are based off of Adequate Intake (AI) values.
- 1-3 years old: 0.5 mg/day
- 4-8 years old: 0.6 mg/day
- 9-13 years old: 0.9 mg/day
Adolescents and Adults
- Males 14 years old and older: 1.3 mg/day
- Females 14 years old and older: 1.0 mg/day
- Females 19 years old and older: 1.1 mg/day
The exact amount required daily depends on gender, age, health, and other medical conditions.
A severe deficiency in riboflavin is rare and often accompanies other B vitamin deficiencies. Some symptoms can include red, swollen, cracked lips, mouth and tongue; aversion to bright light; loss of appetite; weakness; fatigue; depression; anemia; loss of vision and dermatitis. Deficiencies in riboflavin may be associated with an increase to throat and esophageal cancers. Those who are at lactose intolerant are at risk for riboflavin deficiencies as well.
Sources in the Diet
The richest sources of riboflavin include organic meats, milk, yeast, cheese, fish and dark leafy green vegetables. For example; lamb, salmon, spinach, milk, mackerel, veal, eggs and feta milk are good sources of riboflavin.
