Faytamiin B2 (riboflavin) waxa laga soo saaraa khamiirka gulukooska, urea, iyo cusbada macdanta ee halsano aerobic.
Cunsurka nafaqeynta ee laga helo caanaha, ukunta, shaciirka malted, beerka, kelyaha, wadnaha, khudaarta caleenta leh.Ilaha dabiiciga ah ee ugu qanisan waa khamiir.Qadar daqiiqado ah ayaa ku jira dhammaan unugyada dhirta iyo xayawaanka.Vitamin (kofactor enzyme).

riboflavin (Vitamin B2) waxaa loo isticmaalaa diyaarinta daryeelka maqaarka sida shucuureed.Waxaa laga heli karaa alaabta daryeelka qorraxda sida kor u qaadaysa suntan.Daawo ahaan, waxa loo isticmaalaa daawaynta nabarada maqaarka.
Riboflavin waa fitamiin B2 ee biyaha ku milma ee looga baahan yahay maqaarka caafimaadka qaba iyo dhismaha iyo ilaalinta unugyada jirka.waa jaale ilaa liimi-jaale budo crystalline ah.waxay u shaqeysaa sida coenzyme iyo sidaha hydrogen.way xasiloon tahay kulaylka laakiin waxa laga yaabaa inay milmaan oo ay ku lumaan biyaha karinta.aad bay u deggan tahay kaydinta.Ilaha waxaa ka mid ah khudaarta caleenta leh, farmaajo, ukun, iyo caano.
Yaraanta daran ee riboflavin waxaa loo yaqaana ariboflavinosis, iyo daawaynta ama kahortaga xaaladan waa waxa kaliya ee la xaqiijiyay ee riboflavin.Ariboflavinosis waxaa inta badan lala xiriiriyaa yaraanta fiitamiinada badan taas oo ka dhalatay alkoholmiinta wadamada horumaray.Sababtoo ah tirada badan ee enzymes ee u baahan riboflavin sida coenzyme ahaan, cilladuhu waxay keeni karaan cillado badan oo aan caadi ahayn.Dadka qaangaarka ah ee seborrheicdermatitis, photophobia, neuropathy peripheral, dhiig-yaraan, iyo isbeddellada andoropharyngeal oo ay ku jiraan stomatitis angular, glossitis, iyo cheilosis, ayaa badanaa ah calaamadaha ugu horreeya ee yaraanta riboflavin. Carruurta, joojinta koritaanka ayaa sidoo kale ku dhici karta.Marka ay cilladu sii socoto, cudurro aad u daran ayaa soo baxa ilaa geeridu ka timaado.Yaraanta Riboflavin waxa kale oo laga yaabaa inay soo saarto waxyeellooyin teratogenic ah oo ay beddesho maaraynta birta oo horseedda dhiig-yaraan.
