Vitamin B2(vb2)
Deficiency and Toxicity
- Deficiency Symptoms: Long-term insufficient intake may lead to symptoms such as cracked lips, sore tongue, eye fatigue, photophobia, and skin rashes. Severe deficiency can also affect the normal function of the nervous system and hematopoietic system.
- Toxicity: Vitamin B2 has a low toxicity risk because excess amounts are readily excreted in urine, which may cause urine to turn bright yellow—a harmless side effect. No serious adverse effects have been reported with high-dose oral intake.
