Acide folike ikoreshwa muri emollient.Muri vitro no muri vivo ubushakashatsi bwuruhu noneho bwerekana ubushobozi bwabwo bwo gufasha muri synthesis ya DnA no kuyisana, guteza imbere ingirabuzimafatizo, kugabanya iminkanyari, no guteza imbere uruhu.Hariho bimwe byerekana ko aside folike ishobora kandi kurinda DnA kwangirika kwatewe na uV.Acide Folike ni umwe mu bagize vitamine B kandi isanzwe iboneka mu cyatsi kibisi.
Ubuvanganzo bukunda kwerekana ko vitamine B idashobora kunyura mu ruhu, bityo, nta gaciro ifite ku ruhu.Ubushakashatsi bugezweho burerekana ariko ko vitamine B2 ikora nka moteri yihuta yimiti, ikongerera imikorere ibikomoka kuri tirozine mumyiteguro yihuta ya suntan.
Acide Folique ni vitamine ikungahaye kuri vitamine ifasha muguhimba ingirabuzimafatizo zitukura, ikarinda anemiya zimwe na zimwe, kandi ni ngombwa muri metabolism isanzwe.gutunganya ubushyuhe bwo hejuru bigira ingaruka ku gihagararo cyacyo.nibyiza kubikwa munsi yubushyuhe bwicyumba.nanone yitwa folacin.iboneka mu mwijima, imbuto, n'imboga rwatsi.
Vitamine ikenewe muguhuza ADN, gukora ADN no gusana ADN ya methylate, ikora kandi nka cofactor mumyitwarire yibinyabuzima irimo folate.
