Essential Vitamins and Minerals our Body Needs

essential vitamins and minerals

As we know vitamins and minerals are essential nutrients that our body needs – but what does each vitamin do? And which foods are vitamin powerhouses?

Vitamins and minerals are essential nutrients because they perform many roles in our bodies. They help elevate bones, heal wounds and enhance our immune system.

There is a very fine line between getting enough of these nutrients (which are healthy) and getting too much (which can harm you). Eating a healthy diet is the best way to get adequate amounts of the vitamins and minerals you need.

Essential Vitamins and Minerals requirement in our body

Every day, our body produces bone and muscles. It nourishes rich red blood that carries nutrients and oxygen to distant outposts, and it sends nerve signals with skipping over thousands of miles of brain and body passages. It also prepares chemical messengers that travel from one organ to another, issuing instructions that help maintain our life.

But to do all this, our body needs some raw materials. These include many vitamins, minerals, and dietary components that our body requires but cannot manufacture in sufficient quantities.
