Most people know that vitamins are, as the word suggests, nutrients vital to well-being. But what’s not as well known is that no one vitamin is capable of optimally supporting health all by itself.
Vitamins can only function optimally in the presence of other nutrients, such as essential minerals and other vitamins. That’s one reason nutrition authorities encourage people to consume a diet that primarily consists of whole foods, which naturally contain a wide variety of vitamins and their beneficial cofactors.
It’s also why high-quality multivitamin/mineral supplements provide such a wide range of nutrients: This approach allows each vitamin or mineral to function optimally within the body.
