They can be assimilated thanks to a varied diet – rich in proteins, fats, vegetables and fruits or by supplementation. Despite everything, it is important that our lives do not run out of vitamins. At the same time, there should not be too many of them, because apart from avitaminosis, we may also develop hypovitaminosis or hypervitaminosis. What are vitamins and why do we need B vitamins?
Vitamins – what is it?
It is a group of organic chemical compounds with diverse structure, necessary for the proper functioning of the living organism. They may be of natural origin or obtained synthetically. For man, vitamins are exogenous (our body does not produce them), therefore they must be obtained in food (usually in the form of provitamins) or dietary supplements. Antivitamins – compounds blocking the absorption of vitamins – have opposite effects on vitamins. The first discovered vitamin (B1) was separated by the Polish biochemist Kazimierz Funkek in 1913.
Vitamins from group B – properties
Vitamins from group B primarily take responsibility for the proper functioning of the nervous system, and thus – for the mental condition. They soothe nervous tension, have a positive effect on the mood, as well as improve cognitive ability. They play a very important role in metabolic processes, including they are involved in the process of carbohydrate absorption – the transformation of glucose into energy, which is supplied, among others, to the brain. Thus, it improves mental efficiency and mood. These vitamins also perform other tasks. What?
Vitamin B1 (thiamine) – Thiamine facilitates the work of the cardiovascular system, helps to overcome seasickness and shingles, as well as affects proper bone growth and development;
Vitamin B2 (riboflavin, vitamin G) – The presence of riboflavin is required for the proper functioning of the human immune system, it improves the condition of the skin, hair and nails, strengthens the eyesight, supports the treatment of anemia and diseases of the mouth, lips and tongue. Its deficiency may contribute to the development of oesophageal cancer;
Vitamin B3 (Niacin, Vitamin PP) – Niacin participates in the metabolism of sex hormones (estrogen, progesterone and testosterone), cortisol, thyroxin and insulin and in the formation of red blood cells. In addition, it lowers the level of cholesterol in the blood, counteracts gastrointestinal disorders. It is suggested that it may support the therapy of schizophrenia;
Vitamin B4 (choline) – Vitamin B4 is responsible for the creation and maintenance of normal cell structure, as well as for controlling the function of the muscles, respiratory system, heart rate and memory work of the brain. In addition, it participates in the regulation of lipid metabolism;
Vitamin B5 (pantothenic acid) – Pantothenic acid, as a coenzyme A, participates in modifications related to energy management in the body, including in the metabolization of fatty acids. takes also involved in the synthesis of cholesterol, steroid hormones, vitamins A and D. In addition, it inflates the production of bile, red blood cells. It also causes signs of arthritis, prevents hair loss and graying. It strengthens the immune system and prevents the side effects of antibiotic therapy;
Vitamin B6 (pyridoxine) – Vitamin B6 has an important function in the transformation of protein (facilitates its absorption), fat-soluble vitamins and tryptophan (helps in its modification into vitamin B3). In addition, it affects glycogenesis and glycogenolysis in the muscles. Its presence is necessary for the production of hemoglobin, has an effect on blood pressure, muscle spasms (relieves the night leg muscle spasms, hand suffering). In addition, it increases the body’s immune system and is involved in the production of antibodies. It probably improves the effects of autism treatment;
Vitamin B7 (biotin, vitamin H) – As a coenzyme, carboxylase is involved in the synthesis of, among others, fatty acids. Biotin also affects the proper growth and development of the body, proper skin condition (eliminates bumps and inflammatory processes, also works positively in the case of eczema), prevents hair graying and baldness;
Vitamin B8 (inositol) – Vitamin B8 (inositol) is defined as a substance affecting insulin sensitivity;
Vitamin B9 (folic acid) – Folic acid is necessary for the synthesis of DNA (determines the proper division of cells). This vitamin prevents congenital, also neurological, defects. In addition, it strengthens the functioning of the hematopoietic system (prevents anemia), nervous (participates in the creation of nerve transmitters, which take responsibility, inter alia, for well-being, sleep and appetite) and has an important role in homocysteine metabolism;
Vitamin B12 (cobalamin) – Helps to create red blood cells, metabolize proteins, fats and carbohydrates and synthesize serotonin;
Vitamin B15 (pangamic acid) – Lowers cholesterol;
Vitamin B17 (amygdalin) – Anticancer works
