riboflavin (Vitamini B2) amagwiritsidwa ntchito pokonzekera chisamaliro cha khungu ngati emollient.Itha kupezeka muzinthu zosamalira dzuwa ngati chowonjezera cha suntan.Mankhwala, amagwiritsidwa ntchito pochiza zotupa pakhungu.
Riboflavin ndi vitamini B2 wosungunuka m'madzi wofunikira pakhungu lathanzi komanso kumanga ndi kusunga minofu yathupi.ndi ufa wakristalo wachikasu kupita ku lalanje-chikasu.imagwira ntchito ngati coenzyme komanso chonyamulira cha haidrojeni.Ndiwokhazikika potentha koma imatha kusungunuka ndi kutayika m'madzi ophika.ndi yokhazikika posungira.Magwero ake ndi masamba a masamba, tchizi, mazira, ndi mkaka.
Kuperewera kwakukulu kwa riboflavin kumadziwika kuti ariboflavinosis, ndipo kuchiza kapena kupewa matendawa ndi umboni wokhawo wa riboflavin.Ariboflavinosis nthawi zambiri imalumikizidwa ndi kuchepa kwa mavitamini angapo chifukwa cha uchidakwa m'maiko otukuka.Chifukwa cha kuchuluka kwa ma enzymes omwe amafunikira riboflavin ngati coenzyme, kuperewera kungayambitse zovuta zambiri.Kwa akuluakulu seborrheicdermatitis, photophobia, peripheral neuropathy, anemia, andoropharyngeal kusintha kuphatikizapo angular stomatitis, glossitis, ndi cheilosis, nthawi zambiri zimakhala zizindikiro zoyamba za kuchepa kwa riboflavin.Pamene kuperewera kukukulirakulira, ma pathologies owopsa amakula mpaka kufa.Kuperewera kwa riboflavin kumatha kubweretsanso zotsatira za teratogenic ndikusintha kagwiridwe kachitsulo komwe kumayambitsa kuchepa kwa magazi.
