Vitamins- how do they change your body?


Hi! I just started taking a multivitamin and biotin vitamin everyday and I want to know what changes you can see physically once you start taking vitamins. I can't find anything about it on google.
For example, the types of answers im looking for are like for biotin, how it can help your hair and nails more quickly.
Thanks!
