Can vitamin B2 be taken for a long time

Vitamin B2 can generally be taken for a long time, but the dosage needs to be adjusted according to individual circumstances and doctor's advice. Vitamin B2 is a water-soluble vitamin, and excessive amounts may be excreted in urine, but long-term high-dose consumption may cause mild side effects. Vitamin B2, as an essential nutrient for the human body, participates in energy metabolism and cellular respiration processes. Under normal dietary conditions, the daily requirement for adults is about 1.1-1.3 milligrams, which can be obtained through dairy products, eggs, lean meat, and other foods. For patients with symptoms of vitamin B2 deficiency such as angular stomatitis and glossitis, doctors may recommend short-term supplementation of treatment doses. Special populations such as pregnant women, alcoholics, or patients with digestive and absorption disorders can have their supplementation period extended under the supervision of a doctor.

Long term daily intake of more than 50 milligrams may cause reactions such as yellowing of urine and diarrhea. Some drugs, such as antipsychotics and antibiotics, may affect vitamin B2 metabolism, and attention should be paid to their interactions. Patients with autoimmune diseases, renal insufficiency, and other special populations need to strictly control the dosage of supplements. Clinical studies have shown that continuous overdosing may interfere with thyroid hormone test results, and it is recommended to regularly review relevant indicators during medication.

It is recommended to prioritize meeting vitamin B2 needs through a balanced diet, with whole grains, dark green vegetables, and nuts being good sources. During the period of taking supplements, fasting should be avoided as taking them with food can increase absorption rate. Seek medical attention promptly when experiencing abnormal reactions such as persistent skin itching and blurred vision. Regularly conduct nutritional assessments, adjust supplementary plans based on blood test results and doctor guidance, and avoid blind long-term use.
