Vitamin B2
In this post, we will focus on another water-soluble vitamin referred to as Vitamin B2. We will review its roles and sources.
Vitamin B2 is also known as Riboflavin.
Functions Of Vitamin B2
- Carbohydrate metabolism-Vitamin B2 is an important coenzyme involved in multiple oxidation-reduction reactions required in carbohydrate and protein metabolism.
- For cell development and function –It is actively involved in the formation of red blood cells.
Sources Of Vitamin B2
- Dairy products-cheese, whey, milk
- Organ meats-liver, kidneys
- Eggs
- Nuts -almonds
- Can be found in insignificant amounts in vegetables such as spinach
RDA
- Males ≥ 19 years -1.3 milligrams
- Females ≥ 19 years -1.1 milligrams
- Pregnant women -1.4 milligrams
- Lactating women -1.6 milligrams
Individuals At Risk Of Vitamin B2 Deficiency
- Vegans –You must have noticed that vitamin B2 is mainly contained in animal sources such as dairy products. Vegans may be predisposed to its deficiency considering their complete omission of animal-based foods.
- Pregnant and lactating women-They have increased Vitamin B2 needs, and failure to meet these increased needs likely predisposes them to its deficiency.
- Individuals with poor diets-Individuals who consume diets deficient in micro-nutrients are more susceptible to Vitamin B2 deficiency.
- Individuals with certain conditions-Thyroid disorders are associated with an increased risk for Vitamin B2 deficiency.
Vitamin B2 deficiency is likely to occur alongside other Vitamin B deficiencies, in that, it rarely occurs alone. Furthermore, it could also occur along with other conditions such as under-nutrition.
Vitamin B2 Deficiency
A riboflavin deficiency is characterized by :
- Cracked lips
- Sore throat
- Anaemia
- Lesions around the lips and mouth
- Glossitis- Swelling of the tongue
- Hair loss
- Eye infections
- Skin rash
Vitamin B2 Toxicity
Vitamin B2 lacks an established toxicity level. Moreover, toxicity is unlikely to result from the intake of food sources alone.
Nutrient Interactions With Vitamin B2
Zinc, Vitamin B3 (niacin), and Vitamin B2 work together to promote the conversion of vitamin B6 (pyridoxine) into its functional form for utilization in the body.
Drug Interactions With Vitamin B2
- Methotrexate – Methotrexate, (medicine used in the treatment of cancer and autoimmune diseases such as rheumatoid arthritis ), may impede the body’s utilization of vitamin B2.
- Phenytoin – Phenytoin(a drug for managing epileptic seizures) may interfere with the vitamin B2 levels in the body.
A nutritious diet that incorporates various micro-nutrients is essential.Obtain sufficient amounts of Vitamin B2 from its sources such as dairy products, and nuts.
