How many of you know exactly what vitamins are and what they are used for? They are essential substances called micronutrients, because they are sufficient in small quantities, and since our body is unable to synthesize them or do it sufficiently, we must necessarily take them with food. With the iherb code hk you can make the purchase of the vitamin pills in the best price.
Vitamin A: contains retinol and carotenoids, it is important for sight, for the immune system and for cell differentiation. It is found preformed in foods of animal origin (liver, milk, eggs, fish) while in vegetables it is in the form of a precursor, carotene, abundant in vegetables and yellow-orange and deep green fruits, where there is chlorophyll.
Groups
The B vitamins: they are 8 and are extremely common in the plant kingdom (except B12) and all in the animal kingdom. They are essential for the functioning of the nervous system and in the formation of red blood cells and other blood cells, as well as participating in the energy metabolism of glucose, fats and proteins.
VitB1 (Thiamine), B2, B3, B5, B6, B7, B9, and B12 are considered energetic even if they do not supply calories, because they support normal energy metabolism, while B12 and folic acid contribute to the normal function of the immune system and to the formation of hemoglobin, whose deficit causes serious anemia and deficit of the nervous system.
Vitamin C: known as ascorbic acid, it is a molecule that is not stable to temperature and light, therefore cooking the food in which it is contained, mainly fruit and vegetables, reduces its concentration. VitC performs its function in the correct formation of collage, and therefore it is essential for the good condition of blood vessels, bones, teeth, and in addition to supporting the immune system it is a powerful antioxidant.
The Vitamin D: called colecalciferol, is fundamental to the fixation of calcium, and therefore contributes to maintaining the mineralization of the bones of the skeleton. In reality it is not a Vitamin in the strict sense, because thanks to sunlight the body can synthesize it and accumulate it in the summer months, to use it constantly during the winter.
Vitamin E: it is present in nature as “tocopherol”, a powerful antioxidant typical of vegetable fats, wherever they are found, such as in whole grains, in fresh or dried fruit, in shell or in vegetable oils. It is used to combat the oxidation of fats both in food and in cell membranes and promotes the functioning of the central nervous system, which is very rich in oxidizable fats. Supplements of this vitamin, even if fashionable, do not serve at all, because when we eat fatty foods, or season with olive oil, we also take its antioxidant.

Vitamin K:Phylloquinone is also synthesized by intestinal bacteria, but inadequate to the needs, and is present in all green leafy vegetables, as well as in meat, legumes, cheeses and dairy products, and is important in the blood coagulation process in which it is involved in the first row, even if there are no known deficiencies in the adult individual.
