Vitamins that are not made in the body

Vitamins are the compounds that everyone needs to stay healthy. Most of times we need to eat food to provide vitamins. Because some of them are not produced in the body or are made in small quantities. In this article, we will talk about vitamins, their different types and introduce vitamins that are not produced in the body.

What is a vitamin?

Vitamins are substances that are present in small amounts in natural foods. Having small amounts of certain vitamins in the body may increase the risk of some diseases.

Types of vitamins

Vitamins are divided into two general categories: fat-soluble and water-soluble. In the following, we will explain these two categories.

Fat-soluble vitamins

Vitamins A, D, E and K are fat soluble. The body stores fat-soluble vitamins in adipose tissue and liver. These vitamins can stay in our body for days and sometimes months. The body absorbs fat-soluble vitamins through the intestinal tract.

Water-soluble vitamins

Water-soluble vitamins do not stay in the body for long. They are excreted in the urine and cannot be stored. That’s why people need regular intake of these vitamins. Vitamin C and all B vitamins are Water-soluble.
