Eli5: what exactly are vitamins and how do they benefit us biologically?
In: 4
vitamins are essential molecules that are either co-enzymes or co-factors for a lot of chemical reactions in the body.
They’re not just beneficial, they are essential. Meaning, you need them to have normal functions. The reason why we need to take certain vitamins is because we’ve lost the ability to make some of them. Some animals can make their own certain vitamins.
