Vitamins are organic compounds necessary for the proper functioning of the human body. They were discovered relatively early, because it was only in the twentieth century. Their properties can be compared to the properties of hormones, they are coenzymes in metabolic processes. Our body, in comparison to fats, proteins or carbohydrates, does not need a large number of vitamins, but their lack may negatively affect physical fitness and general well-being. Vitamin deficiencies can lead to problems with metabolism.
We can divide them into fat-soluble and water-soluble vitamins. Fat-soluble vitamins are resistant to technological processes, such as frying and cooking. This group includes only four vitamins: A, D, E and K. The human body can store them and their surpluses can be toxic to us. They depose in the liver and adipose tissue.
Vitamin A protects against cancer and prevent heart diseases. It improves the appearance of the skin, hair and nails, improves eyesight and hormone production. Vitamin A has an important function in protein syntethis. It helps vitamin E to strengthen the immune system and to enhance body detoxification. As an antioxidant, it protects the body's cells against the harmful effects of free radicals. Its deficiency can promote eye defects, problems with skin and nails.
Vitamin E primarily counteracts the processes of aging of the body. It protects cells against oxidation of fatty acids that build cell membranes. It is a powerful antioxidant that neutralizes free radicals. It smoothes the skin and accelerates wound healing. Deficiency of this essential vitamin can cause insomnia and fatigue.
Vitamin D has a positive effect on the condition of human bones. Prevents rickets and tooth loss. Our body produces it thanks to UV radiation. The excessive amount of vitamin D is toxic for the body. Overdose is manifested by vomiting, damage to the arteries and calcification of the kidneys.
Vitamin K forms bone tissue. It inhibits haemorrhage and has a beneficial effect on blood clotting. It has antibacterial and antifungal properties. It is produced by intestinal bacteria. The excess of this vitamin occurs more often than a deficiency and can lead to anemia.
Water-soluble vitamins are B vitamins (B1, B2, B5, B6, B9, B12, Vitamin PP), vitamin H (Biotin), vitamin C. B vitamins affect many processes occurring in the body. They have a positive effect on the metabolism and production of red blood cells. They improve the condition of the skin, hair and nails. These vitamins are helpful in treating muscle spasms. They favorably affect the functioning of the nervous system and strengthen immunity.
Vitamin H, or biotin. First of all, it supports the proper functioning of the thyroid gland. Second it supports the synthesis of amino acids, fatty acids and proteins.
Vitamin C stimulates the immune system. Additionally, it participates in metabolic processes. Stimulates the synthesis of collagen, proteins and lowers cholesterol and has an anti-cancer effect. Its deficiency leads to feelings of tiredness and slower wound healing.
