thioctic acid, lipoic acid
Vitamin N is found in various organs in the body, but most of it is found in the liver, kidneys and heart.
Vitamin N rich foods
Indicated approximate availability in 100 g of product
Daily requirement of vitamin N
According to some sources, the daily requirement for vitamin N is 1-2 mg per day. But in the methodological recommendations of MR 2.3.1.2432-08, the data are 15-30 times larger!
The need for vitamin N increases with:
- going in for sports, physical work;
- in cold air;
- pregnancy and lactation;
- neuro-psychological stress;
- work with radioactive substances and pesticides;
- a large intake of protein from food.
Digestibility
Vitamin N is well absorbed by the body, and its excess is excreted in the urine, but if there is not enough (Mg), absorption is noticeably impaired.
Useful properties and its effect on the body
Vitamin N participates in biological oxidation processes, in providing the body with energy, in the formation of coenzyme A, which is necessary for the normal metabolism of carbohydrates, proteins and fats.
Lipoic acid, participating in carbohydrate metabolism, ensures the timely uptake of glucose by the brain – the main nutrient and source of energy for nerve cells, which is an important point for improving concentration and memory.
In the body, lipoic acid is associated with protein, especially closely with the amino acid lysine. Lipoic acid-lysine complex is the most active form of vitamin N.
Lipoic acid has a protective effect on the liver, lowers blood sugar, promotes growth, and normalizes fat and cholesterol metabolism. Lipoic acid plays a protective role when toxic substances enter the body, in particular, salts of heavy metals (mercury, lead, etc.).
Interaction with other essential elements
Lipoic acid inhibits oxidation and.
Lack and excess of vitamin
Signs of a vitamin N deficiency
- indigestion;
- skin allergies.
There were no pronounced specific symptoms of a lack of lipoic acid. However, it is known that with disturbed processes of assimilation of vitamin N and its insufficient intake with food, liver dysfunctions occur, which leads to its fatty degeneration and impaired bile formation. The occurrence of atherosclerotic vascular lesions is also a sign of a lack of lipoic acid.
Signs of excess vitamin N
Excess lipoic acid obtained from food is excreted from the body without negatively affecting it. Hypervitaminosis can develop only with excessive administration of vitamin N as a medicine.
The main symptoms of excess lipoic acid are: increased acidity of the stomach, heartburn, pain in the epigastric region. Allergic reactions are possible, manifested by skin lesions with inflammatory processes.
Why Vitamin N Deficiency Occurs
Deficiency of lipoic acid in the body can occur with cirrhosis of the liver, skin diseases, insufficient intake of vitamin B1 and protein.
