Vitamin B2 Deficiency, Causes, Symptoms And Treatment

Vitamin B2, also known as riboflavin, is an essential nutrient that plays a crucial role in maintaining overall health. It is involved in various processes in the body, including energy production, metabolism of carbohydrates, fats, and proteins, and maintenance of healthy skin, eyes, and nervous system. A deficiency of vitamin B2 can lead to several health problems. Here’s some information about vitamin B2 deficiency:


Inadequate Intake: Vitamin B2 deficiency can occur when your diet lacks sufficient sources of riboflavin. This can happen due to poor dietary choices or following restrictive diets.

Impaired Absorption: Certain medical conditions, such as Crohn’s disease, celiac disease, and chronic alcoholism, can interfere with the absorption of vitamin B2 from the food you consume.

Increased Requirements: Some individuals may have higher requirements for vitamin B2 due to factors like pregnancy, breastfeeding, intense physical activity, or certain medications that increase its excretion.


Fatigue and Weakness: Vitamin B2 is involved in energy production, so a deficiency can lead to feelings of fatigue, weakness, and a general lack of energy.

Skin and Oral Problems: Deficiency may cause skin issues like dryness, cracks at the corners of the mouth (cheilosis), a sore or swollen tongue (glossitis), and inflammation of the lining of the mouth (stomatitis).

Eye Disorders: Riboflavin deficiency can result in sensitivity to light (photophobia), itchy, watery eyes, and blurred vision.

Digestive Problems: Some individuals may experience digestive symptoms like nausea, loss of appetite, and abdominal pain.

Neurological Symptoms: In severe cases, neurological symptoms such as tingling or numbness in the extremities and cognitive disturbances may occur.

Treatment and Prevention

Dietary Changes: Including food sources rich in vitamin B2 in your diet is the primary treatment and prevention strategy. Good sources of riboflavin include dairy products, lean meats, eggs, green leafy vegetables, whole grains, and fortified cereals.

Supplements: In cases of severe deficiency or when dietary changes are not sufficient, riboflavin supplements may be recommended under the guidance of a healthcare professional.

Addressing Underlying Conditions: If the deficiency is caused by a medical condition or medication, treating the underlying cause or adjusting the medication may be necessary.

Balanced Diet: Maintaining a well-rounded diet that includes a variety of nutrient-rich foods is essential for preventing deficiencies of all types.

If you suspect a vitamin B2 deficiency or are experiencing concerning symptoms, it’s recommended to consult with a healthcare professional for proper diagnosis and guidance. They can evaluate your specific situation and provide appropriate advice or treatment.
