9794. Вітамін B2

Vitamin B2, also known as riboflavin, is a water-soluble B-group vitamin that plays an important role in metabolism and energy production. It is essential for the formation and maintenance of red blood cells, antibody synthesis, tissue growth, and cellular respiration. Vitamin B2 improves eye health, reduces eye fatigue, and plays an important role in the prevention of cataracts. Vitamin B2 is obtained from food sources. Testing is recommended to diagnose vitamin B2 deficiency in the presence of characteristic symptoms such as inflammation of the oral mucosa, seborrheic eczema on the face and other parts of the body, conjunctivitis, photophobia, decreased light and color sensitivity, cataracts, or normocytic, normochromic anemia.

Vitamin B2 (riboflavin) is a water-soluble vitamin that belongs to the B-group vitamins. It acts as a coenzyme for many essential oxidation-reduction enzymes, participating in protein, fat, and carbohydrate metabolism, maintaining normal visual function, supporting the synthesis of hemoglobin and erythropoietin, increasing glycogen content in the liver, and enhancing its detoxifying capacity. Dietary sources of vitamin B2 include milk and dairy products, yeast, whole-grain bread, cereal seeds, eggs, meat, fresh vegetables, and fruits. It is also partially synthesized by the intestinal microflora.

The body’s demand for vitamin B2 increases with intense physical activity, use of oral contraceptives, and excessive alcohol consumption (which impairs vitamin B2 absorption).

Insufficient intake or absence of vitamin B2 in the diet leads first to hypovitaminosis, and then to avitaminosis B2. In addition to dietary deficiency, there are rare congenital metabolic disorders, mostly associated with impaired riboflavin transport, which result in a functional deficiency of vitamin B2.

Symptoms of vitamin B2 deficiency include inflammation of the lips and oral mucosa, seborrheic eczema on the face and other body areas, conjunctivitis, photophobia, decreased light and color sensitivity, and cataracts. In cases of severe deficiency, individuals may develop general muscle weakness, cardiac muscle weakness, degenerative changes in the nervous system, anemia, and ulcerative colitis.

Screening of individuals at risk:

• Venous blood
