What is Vitamin B2?

Vitamin B2 (Riboflavin) was first recognized as a greenish yellow pigment in milk in 1879. It is a water-soluble vitamin with no known toxic effects. Riboflavin cannot be stored and must be replenished regularly from food or from supplementation. Any surplus is excreted in the urine which may give the urine a yellow/green fluorescent color.

Why is Vitamin B2 important and what does it do in the body?

Like many B vitamins, vitamin B2 is very important for the success of many body reactions. It forms part of two important enzymes called FMN and FAD which help manufacture energy, primarily from carbohydrates, but also from fats and proteins. It's commonly known as one of the energy vitamins for this reason! Our DNA and RNA are comprised of nucleic acids and riboflavin is required to make these. In combination with vitamin A, it also contributes to good vision. B2 helps maintain healthy skin, nails and hair and promotes growth, fertility and the uptake of iron (assimilation) as it promotes iron binding capacity and serum ferritin levels. It may also benefit individuals suffering from migraines and sickle cell anemia. Glutathione is one of the body’s main protectors against free radical damage and oxidative stress and riboflavin is involved in regenerating this essential substance.

What amount of Vitamin B2 do you need each day?

Recommended daily allowances are given as a guide to prevent illness. If you are active and expend more energy then you will use more Vitamin B2 and you will require a higher intake than someone who is sedentary.

The DRI (Daily Recommended Intake) /RDA (Recommended Daily Allowance) of dietary vitamin B2 are listed below:

Please Note: By definition, the DRI/RDA recommendations apply only to 98% of healthy individuals and are not sufficient for those with higher nutrient requirements based upon their biochemical individuality, genetics, health status, medications, deficiencies, lifestyle, and toxic exposures.

Daily recommendations for Vitamin B2 are listed below.

Pediatric

  • Infants birth - 6 months: 0.3 mg     (adequate intake)
  • Infants 7 - 12 months: 0.4 mg (adequate     intake)
  • Children 1 - 3 years: 0.5 mg (RDA)
  • Children 4 - 8 years: 0.6 mg (RDA)

  • Women 19 years and older: 1.1 mg (RDA)
  • Pregnant women: 1.4 mg (RDA)
  • Breastfeeding women: 1.6 mg (RDA)

Riboflavin is best absorbed when taken between meals. People who do not eat a balanced diet every day may benefit from taking a multivitamin and mineral complex.
