Vitamin B functions in the human body. Vitamin B three times differently: what functions do they provide in the human body? If you have yet to believe that vitamin B is just one, then you are mistaken. Within the vitamin B group, there are a number of different species that fulfill their specific function in the human body. Their deficiency can then lead to disorders of some functions of the body and other health complications such as memory problems, high fatigue, or a tendency to depression. It is therefore important to realize how these vitamins affect our organism and to ensure their balanced intake.
Vitamin B functions in the human body
Vitamin B1 – thiamin
Thiamin has a positive effect on the nervous system and also has a beneficial effect on fatigue. Its major drawback, however, is that the human body can not store this vitamin for a longer period of time, its supply is usually sufficient for 4-10 days. Additionally, many times, our own diet unconsciously inhibits the absorption and effects of thiamine, especially if we drink more coffee or tea, so it is necessary to supplement vitamin B1 daily.
In the event of a great physical exertion or a long stressful period, it is also necessary to increase the intake, as well as a regular intake of certain diseases, pregnancy, or nicotine poisoning. If vitamin B1 is deficient in the body, it is paradoxically associated with high levels of fatigue, combined with insomnia, poor concentration, headaches, irritability, weight loss, and anorexia. If the patient is not treated, the symptoms arise and depression, confusion and melancholic conditions appear. However, if you focus on your diet, which regularly includes dishes containing brewer’s yeast, potatoes, beans, pork, poultry, fish, cereals, or nuts, you do not have to worry about the lack of thiamine.

Vitamin B2 – riboflavin
This vitamin helps the body burn sugars, but it is often deficient in the body. This can be due to a number of diseases, particularly those with thyroid disease, celiac disease, cirrhosis of the liver, or diabetes. With the loss of riboflavin, there may also be individuals undergoing antibiotic therapy, adolescents, elderly people, or newborns who have had neonatal jaundice. Vitamin B2 deficiency in the human body causes cracked and sensitive corners of the mouth, inflammation of the larynx, esophagus, and oral cavity, inflammation of the skin and eyelids including possible conjunctivitis, corneal skin, excessive ointment hair, nails, or increased sensitivity to light. These conditions can be avoided by eating a diet rich in milk, eggs, yeast, cocoa, curd, pork, beef, and veal, or fish and potatoes.
Due to the fact that the most important sources of vitamin B2 are the food of animal origin, people with other dietary preferences, especially vegetarians and vegans, may suffer from this deficiency. It is therefore not a good idea to focus on eating the appropriate dietary supplements in addition to traditional foods.

Vitamin B3 – Niacin
Niacin contributes to the proper functioning of the brain, assures the breakdown of certain components of cholesterol and fats from the body, and is part of the glycolysis process. Sufficient intake should be taken especially by pregnant and breastfeeding women or people with kidney disease, but they need also to increase with drinking alcohol and consuming more foods containing refined sugars. If the organism has a niacin deficiency, loss of appetite and loss of weight, insomnia, abdominal pain, tongue and mucous membranes of the mouth, body weakness or nervousness are lost. A serious lack of vitamin B3 can cause Pelagius, a disease that can lead to dementia.
However, if you take care of a balanced diet including yeast, liver, pastry, potatoes, milk, and other dairy products, niacin deficiency should not pose any threat to you.
