The Importance of Vitamins in the Human Body


Vitamins are organic substances which the human body requires in small amounts. The vitamins are essential for life, and they are needed for a wide range of metabolic processes. They are involved in energy metabolism as coenzymes and for general cellular growth. The human body does not produce vitamins and they must be obtained from the foods we eat.

As they are very small (less than 100 daltons), many of them cannot be stored in our bodies and have to be replaced often. The ones that can be stored include Vitamin A, D, E and K. Their levels in the body are monitored by what is called a tightly regulated pathway which ensures that one never becomes deficient or toxic with these vitamins.

What foods contain them?

A lot of foods contain vitamins, what we eat every day. It is difficult to make a list but what’s important is what foods are good for energy boost. This is what we’re going to write about in this article at what kind of food or what vitamin that provides an energy boost.

The foods that contain vitamins are: milk, potatoes, green vegetables and fruits. Milk, especially milk in chocolate is a very good vitamin source. Green vegetables like spinach and broccoli are rich in vitamin C, what our body needs every day to keep healthy. Very importantly what make the list are potatoes.

What Vitamins are Important to Humans?

The human body needs the vitamins for energy metabolism and growth.  The two main types of vitamins are fat-soluble and water-soluble. They are absorbed in different ways, and what they do differs.

Fat-soluble vitamins are absorbed via the digestive tract. They travel in the bloodstream to different parts of the body, where they help with a range of metabolic processes.

Water-soluble vitamins dissolve easily in water and are not stored by the body for long. They are carried in the bloodstream to various parts of the body where they are required for metabolic processes. The most important water-soluble vitamins include vitamin C and the B complex vitamins (thiamine, riboflavin, niacin, pyridoxine or vitamin B6, folate or vitamin B9 etc).

What health problems can they help with?

Vitamins are used to treat and prevent a variety of diseases. For example, vitamins can be used to treat or help reduce the symptoms of anemia, asthma, cancer, cardiovascular disease, cavities, cataracts and digestive problems.
