Hi welcome to HCM
I can understand your concern for yellow colour urination .
Dear for your info , Urine naturally has some yellow pigments .
Dark urine is most commonly due to
dehydration. However, it may be an indicator that excess, unusual, or potentially dangerous waste products are circulating in the body.
In your case , it is evident that medication you are taking is responsible for that , specially vitamin b complex causes yellow color urine . It is natural and should not be the cause of concern .
.In any case , hydrate yourself sufficiently .
Take your Your doctor' s advice , in case you feel anything unusual .
Hope this helps solve your query .
Take care , all the best
