Eli5: [ELI5] What qualifies a chemical or mineral as a “vitamin?” Are all vitamins good for you in proper dosages?
In: Biology
A vitamin is an essential nutrient that can’t be synthesized in the body and must be obtained through diet. So anything you need but can’t make yourself is a vitamin. And for example while we need Vitamin C, there are some organisms that can make their own so in their case it’s not a vitamin.
