ʻO Riboflavin, i ʻike ʻia ʻo ka huaʻa B2, he huaora i loaʻa i ka meaʻai a kūʻai ʻia ma ke ʻano he meaʻai meaʻai.[3]He mea nui ia i ka hana ʻana o ʻelua coenzymes nui, flavin mononucleotide a me flavin adenine dinucleotide.Hoʻopili ʻia kēia mau coenzymes i ka metabolism ikehu, ka hanu cellular, a me ka hana antibody, a me ka ulu maʻamau a me ka ulu ʻana.Pono pū nā coenzymes no ka metabolism o ka niacin, ka huaora B6, a me ka folate.Ua kuhikuhi ʻia ʻo Riboflavin no ka mālama ʻana i ka ʻili ʻana o ka corneal, a lawe ʻia ma ka waha, hiki ke hōʻemi i ka ulu ʻana o ka migraine headache i nā pākeke.

He mea kakaikahi ka hemahema o Riboflavin a ua hele pū ʻia me nā hemahema o nā huaora a me nā meaʻai ʻē aʻe.Hiki ke pale ʻia a mālama ʻia paha e nā mea hoʻohui waha a i ʻole nā ​​injections.Ma ke ʻano he vitamina hiki ke hoʻoheheʻe ʻia i ka wai, ʻaʻole mālama ʻia nā riboflavin i hoʻopau ʻia ma mua o nā pono meaʻai;ʻaʻole i hoʻomohu ʻia a hoʻomoʻa ʻia a hoʻokuʻu koke ʻia i loko o ka mimi, no laila e loaʻa i ka mimi kahi ʻulaʻula melemele.ʻO nā kumu kūlohelohe o riboflavin ka ʻiʻo, ka iʻa a me ka moa, nā hua manu, nā huahana waiu, nā lau ʻōmaʻomaʻo, nā halo, a me nā ʻalemona.Pono kekahi mau ʻāina i ka hoʻohui ʻana i ka palaoa.
