My question is what vitamins help your vaginal health?

Im a very clean person I shower after sex, I shower almost daily and don’t get soap near my actual hole. Just wanted to start taking vitamins cause I’m so tired of UTi symptoms or fully getting UtIs or uncomfortable situations even when nothings wrong. I been to drs so I’m summing it up to my everyday life style I hate cranberry juice by itself but I drink cran apple and it’s beneficial but I go through it quick but I’m looking for other supplements to help it down there.. if anyone has any recommendations. I been to drs when I don’t have infections so I know it’s not any of that and been tested for it all. Just I’ll randomly get uncomfortable for a couple days than it’s gone. My bladder sucks so I think it’s that too. I wanted reviews on the cranberry pills or if anyone else has any recommendations?!
