ELI5: Will eating a multivitamin everyday keep me relatively healthy, even if my diet is not that great?

They provide all my essential vitamins so why would this not work to some extent?

1.) your body only can absorb so many vitamins and minerals at a time. Most of all that is in a multivitamin goes to waste (literally). That’s why your urine is such a dark yellow when on a multivitamin routine.

2.) when you say a not great diet. That presumably means you’re putting in ‘bad’ or too much of something in your body. You can have all the vitamin c you want, but it’s not going to stop you from developing hypertension.

3.) Diet is only one portion of what makes someone’s lifestyle and body healthy. You have to consider exercise, mental health, etc.

That being said, vitamins are perfect for people that cannot consume a specific food group. I.e. vegetarians should try to introduce iron rich food into their diet, vitamins can supplement that.
