Vitamins - which are the most important? [+resources and supplementation].

Vitamins are like superheroes. They are key defenders of health, working in secret, silently. You know they're important and you need to make sure they're in the right concentration in your body. But... well, exactly, but why?"

Ahead of you is a compendium of vitamin knowledge, prepared in collaboration with clinical nutritionist Julia Skrajda. You will get to know each vitamin and see its true value.

What are vitamins?

Vitamins are a group of organic chemical compoundsand. They are essential for the body to function properly. Your body cannot synthesise them (there is an exception to this rule, but about it below) so vitamins need to be taken in with your diet or supplements. 

There are two groups of these compounds - water-soluble vitamins, i.e. the B vitamins and vitamin C, and fat-soluble vitamins, i.e. all the others.

How many vitamins are there?

There are 13and compounds that are considered vitamins. Then there is the so-called vitamin B17 (amigdalin) once used as a cure for cancer. Despite its name, this compound is not classified as a 'real' vitamin .

Water-soluble vitamins

Water-soluble vitamins are absorbed almost immediately by the body. In turn, their excess is removed with the urine. Therefore, an overdose of these compounds is not common, but possible. Water-soluble vitamins include the B vitamins and vitamin C.

Vitamin C

Vitamin C is responsible for the immune system, promotes wound healing, and protects against free radicals. It is essential for the proper functioning of the body.

Properties of vitamin Cand:

• increases immunity,
.
• reduces the risk of chronic diseases,
.
• protects memory,
.
• prevents iron deficiency,
.
• lowers the risk of heart disease,
.
• controls blood pressure,
.

Omega acids, especially omega-3, are also responsible for the prevention of heart disease.You will learn more about them from these articles:

• Omega acids - what they are, types, properties, deficiency
• Omega-3s: characteristics, effects, use, types
.

Resources

Vitamin C is mainly associated with lemon and citrus. But it is present, often in higher concentrations, not only in fruits with the letter C.

Sources of vitamin Cand:

• citrus (orange, kiwi, grapefruit),
.
• strawberries,
.
• tomatoes,
.
• apricots,
.
• potatoes,
.
• brown Brussels sprouts,
.
• cabbage,
.
• broccoli,
.
• cauliflower,
.

Supply and surplus

Deficiency and excess of vitamin C is dangerous for all of us. Too little of this vitamin in the body manifests itself as poorer immunity, slower wound healing, rough skin or weakened bonesand. The classic extreme effect of vitamin C deficiency is scurvy . Symptoms of excess, on the other hand, include headaches, vomiting, diarrhoea or nausea.

Excess

A vitamin A excess is just as dangerous as a deficiency. There are two types of hypervitaminosis: acute and chronic. The former manifests itself with nausea, vomiting, and dizziness, among other symptoms, and is caused by a single intake of a huge dose (more than 200 000 mcg) of vitamin Aand.

On the other hand, chronic hypervitaminosis leads to long-term intake of too much (more than 10 000 mcg per day) vitamin A. Its symptoms include headaches, diarrhoea or skin problems.
