If you have a somewhat balanced diet in this day and age then you will be getting your needed amount of basically everything that's needed on that front, so there is no need, unless advised by a medical professional, to take them.

If you don't have a balanced diet then you might want to take specific vitamins to make up for that, and if you do that via a multi vitamin then I cant imagine it will do you harm (again unless a medical professional tells you otherwise, I'm not a doctor).

And by a balanced diet I don't mean you have to be eating like a health freak, just a normal amount of fruits and veg and that, its surprising how little of that kind of stuff you need to meet the guidelines, a shed load of take aways and ultra processed stuff will cause other types of problems (Obesity, heart disease and the like) but vitamin deficiency without an underlying medical problem is quite hard to get to in the modern western world.
