Nutritional supplements... are they essential medicines and do I really have to take them???

I don't feel it in my body yet and I don't take supplements, so I don't take them.

Looking at this room, it seems like there are a lot of people who eat here every day.

Do I really need to take nutritional supplements??

There are many different types and there are strong likes and dislikes.

What is something I absolutely must eat?

Lutein, omega-3, chondroitin joint supplements, multivitamins, probiotics, arginine iron supplements, magnesium probiotics, vitamins... all of them.

Am I thinking wrong??

Is there a field that says "this is a must"???

Is the basic diet insufficient??
