Vitamins: What Are They and Why Are They Important? – Health


Vitamins are organic substances that are essential for a healthy body and a well-functioning immune system. They are found in food and supplements, and play an important role in various bodily processes. In this article we will take a closer look at the effect of vitamins, whether it is useful to take extra vitamins and we will provide a table with the most well-known vitamins and their effect.

What Are Vitamins?

Vitamins are organic substances that the body needs to function properly. Unlike minerals, vitamins are organic substances that the body cannot produce itself. There are thirteen different vitamins, including A, C, D, E and K. Each vitamin has its own specific function in the body and deficiencies can lead to different health problems.

Should I take extra vitamins?

Most people get enough vitamins through a varied diet. So there is no need to take additional vitamin supplements unless you have a specific vitamin deficiency. In some cases, such as pregnant women or vegetarians, it may be necessary to take additional vitamin supplements to prevent deficiencies. In that case, consult a doctor or dietitian.
