Vitamin B2 ( Riboflavin)

Vitamin B2 ( Riboflavin) is part of the B vitamins group. It has a central role in  metabolism. It is directly involved in the conversion of carbohydrates into energy.

It is also important for the regulation of cellular phenomena being a nourishing and balancing. Its beneficial action is visible on the skin and mucous membranes.
The main changes are obvious lack or delay of the growth and changes in the skin (seborrheic dermatitis) eyes (conjunctivitis and opacity of the lens), and muscle.

Vitamin B2 is found both in food animals and food and vegetables with green leaft (broccoli, asparagus, spinach and turnips). A primary source of Vitamin B2 is the yeast.

A balanced diet is able to supply a sufficient amount of Riboflavin, and then in a healthy subject is not required no integration, in cases instead of sporting subjects integration may be advised through pads of yeast.


It does not seem that over-doses of Vitamin B2 can produce toxic side effects.

Antioxidant

Antioxidants are elements that slow down or prevent the oxidation process of our body.

 

In the human body the oxygen is used to burn food and produce energy for daily activities. Even if the combustion process is necessary it produces molecules dangerous for our body: the Free Radicals.
 

Free radicals are  waste combustion molecules they are atoms with an unpaired electron, they are unstable and harm the dangerous for the body if not kept under control.
 

Antioxidants are involved in the oxidation of cells by oxidation of themselves and then interrupting the continuous formation of free radicals.
able to stop the damage of free radicals that are continuously produced during the combustion process.

 

Free Radicals can also be produced by external factors such as UV rays from the sun, tobacco, pollution and the effects that can be seen is the premature aging of the skin. The endogenous antioxidants are often insufficient so it may be necessary to introduce dietary antioxidants.
 

The dietary antioxidants are Vitamin E, Vitamin C, beta-carotene (Vit.A) and a balanced and varied diet contains all of these nutrients.

Vitamins

Vitamins are organic elements. They don’t have plastic or energy  functions as carbohydrates or fats, but they are essential for cells function and for the organism survival.

Vitamins work as bio-regulators. They acting on specific functions and cellular activities, its role is essential and specific for the proper performance of basic physiological processes.
 

Vitamins are not synthesized by the human body, that's why they must be included in the diet every day. 
 

The term vitamin came from the German, it means  "amine of life" which was the name given by Casimir Funk to the thiamine having identified an amino group in its structure.

Vitamins are distinguished and classified as follows:
 

fat-soluble vitamins, meaning soluble in fat:  vitamins A, D, E, K, F;
 

water-soluble vitamins, meaning soluble in water: vitamin C, B1, B2, B5, B6, PP, B12, Bc, H.

 

Vitamins are found in fruits and vegetables, but also in the milk into the eggs in the fish and other animal products.

Our body needs a certain amount of vitamins.

An excess of some vitamins can be harmful. In fact, fat-soluble vitamins such as vitaminA and D are fixed in the fatty tissues and their accumulation can damage the liver and other organs that are protected from these tissues. The excess of water-soluble vitamins is less dangerous because the amount is eliminated superfluous with sweat or through the urine.
However,it is harder to excess in vitamins with a normal diet without supplements.

The needs  of those Vitamines increases in dependence on environmental factors  or by the age, sex, health stress and physical activity.
