If little of it enters the body with food, then a person begins to experience various symptoms of a substance deficiency: from weakness to the development of severe anemia. In this regard, doctors recommend taking vitamin B2 in tablets during an exacerbation of vitamin deficiencies (more often in the spring).

Vitamin B2, with an excess of its intake, accumulates in the liver, adrenal glands and kidneys. It should be borne in mind that if the patient has inflammation processes in the digestive tract, impaired absorption of nutrients, or in combination with alcohol, vitamin B2 is poorly absorbed by the body.

Important. Only a doctor can prescribe vitamin B2 intake, since an excess of riboflavin in the body is no less dangerous than a deficiency.

The body's daily requirement for vitamin B2:

6-12 months	600
1-3 years	900

Interesting to know. The amount of vitamin B2 decreases in foods if:

they are stored for a long time in direct sunlight;
the dish is cooked open;
long-term storage;
drinking alkaline drinks reduces the absorption of the vitamin.

In addition, eating foods (and vitamin preparations) on an empty stomach reduces the absorption of riboflavin.

when taking riboflavin, the urine acquires a pronounced yellow color;
in the presence of restrictions or chronic diseases, the dosage of the vitamin is set individually;
a vitamin can be prescribed by a doctor only after confirmation of its deficiency in the body, since the above symptoms are not necessarily signs of vitamin deficiency. They can mean other pathologies, as well as a deficiency of folic acid;
riboflavin reduces the effectiveness of antibiotics;
the vitamin is completely incompatible with the antibiotic streptomycin, as well as with ascorbic acid and preparations containing heavy metal salts;
antipsychotics and antidepressants: Chlorpromazine, Imipramine and Amitriptyline, as well as antiepileptic drugs, reduce the effectiveness of vitamin intake, as they activate its removal from the body;
narcotic drugs improve the absorption of the vitamin, as a result, the likelihood of an overdose increases;
with long-term intake of vitamin B2, it is required to control blood coagulation, as well as the amount of iron in the body. The tests are taken approximately 1 time per month;
the drug for gout Probenecid impairs the absorption of riboflavin;
ethanol and antidepressants impair the absorption of vitamin B2;
oral contraceptives impair vitamin absorption;
riboflavin affects the quality of vision and psychomotor reactions. Therefore, when taking a vitamin, you need to drive vehicles and perform hazardous work with caution.

When using vitamin B2 for therapeutic (not prophylactic) purposes, it should be borne in mind that the dosage rules, as well as the course of therapy, are selected individually.
