Mae Profiotigion yn ficro-organebau byw sydd i fod i ddarparu buddion iechyd wrth eu bwyta, yn gyffredinol trwy wella neu adfer fflora'r perfedd .[1][2][3][4] Mae profiotegau yn cael eu hystyried yn ddiogel i'w bwyta ar y cyfan, ond gallant achosi rhyngweithio rhwng bacteria letyol a sgil-effeithiau diangen mewn achosion prin.[5][6][7]

Potel o Yakult, diod profiotig sy'n cynnwys Lactobacillus paracasei

Priodolir y theori wreiddiol, sy'n debyg i'r cysyniad modern, ond nid y term, i'r llawryfwr Nobel Élie Metchnikoff, a nododd fod gwerinwyr Bwlgaria oedd yn bwyta iogwrt yn byw bywydau hirach oherwydd yr arferiad hwnnw.[8]

Mae marchnad profiotigion gynyddol wedi arwain at yr angen am ofynion llymach ar gyfer prawf gwyddonol o'r buddion tybiedig a roddir gan y micro-organebau yr honnir eu bod mewn profiotig.[3] Er bod nifer o fuddion honedig yn cael eu defnyddio i farchnata cynhyrchion profiotig i ddefnyddwyr, megis lleihau anghysur gastroberfeddol, gwella iechyd imiwnedd,[9] lleddfu rhwymedd, neu osgoi'r annwyd cyffredin, nid yw tystiolaeth wyddonol yn cefnogi honiadau o'r fath.[10][11] Mae'r fath honiadau yn cael eu gwahardd fel hysbysebu twyllodrus yn yr Unol Daleithiau gan y Comisiwn Masnach Ffederal .[12] Ers 2019 mae nifer o geisiadau am gymeradwyaeth hawliadau iechyd gan wneuthurwyr Ewropeaidd o atchwanegiadau dietegol profiotig wedi'u gwrthod gan Awdurdod Diogelwch Bwyd Ewrop o herwydd tystiolaeth annigonol o fecanwaith neu effeithiolrwydd buddiol.[13]
