B vitamins B: For the nervous system

B vitamins B: For the nervous system – fundamental leadership

1. The role of group B vitamins in the health of the nervous system: Review

B vitamins, which are a complex of eight water -soluble vitamins, play a critical role in maintaining health and optimal functioning of the nervous system. Each vitamin in this group performs unique functions, but they often work synergically, providing comprehensive support for neurological processes. These vitamins are necessary for:

• Energy metabolism: B vitamins are involved in the transformation of carbohydrates, fats and proteins into the energy necessary to maintain the activity of nerve cells. Nervous cells, neurons, have a high need for energy for transmitting nerve impulses and maintaining cellular metabolism.
• Synthesa neurotransmitted: Some B vitamins are cofactors in the synthesis of neurotransmitters, chemicals that transmit signals between nerve cells. These neurotransmitters affect mood, cognitive functions, sleep and other important aspects of the nervous system.
• Myelinization of nerve fibers: Myelin is a fatty substance that surrounds and isolates the nerve fibers, providing fast and effective transmission of nerve impulses. Vitamin B12 (cobalamin) is especially important for maintaining the integrity of the myelin shell.
• Protection of nerve cells from damage: Group B vitamins, especially B6 (pyridoxine) and B9 (folic acid), have antioxidant properties that help protect the nerve cells from damage caused by free radicals.
• Homocysteine ​​regulation: Vitamins B6, B9 and B12 are involved in the metabolism of homocysteine, amino acids, the elevated level of which is associated with an increased risk of cardiovascular diseases and neurodegenerative diseases. Maintaining a normal level of homocysteine ​​contributes to the health of the nervous system.

2. Detailed analysis of group B vitamins and their influence on the nervous system

Each vitamin of group B plays its unique role in maintaining the health of the nervous system. Consider each of them in more detail:

• B1 (thiamine): “vitamin vigor” for nerve cells

  • Function: Tiamin plays a key role in carbohydrate metabolism, converting them into the energy necessary for the functioning of nerve cells. It also participates in the synthesis of acetylcholine, neurotransmitter, important for memory and learning.
  • Influence on the nervous system: Tiamine deficiency can lead to neurological disorders such as Beri Berie, characterized by peripheral neuropathy, encephalopathy of Vernika and the psychosis of Korsakov. Vernika encephalopathy is manifested by confusion, a violation of coordination and vision problems, and Korsakov’s psychosis is a chronic memory disorder, often associated with alcoholism.
  • Deficiency symptoms: Fatigue, irritability, loss of appetite, muscle weakness, tingling or numbness in the arms and legs, problems with coordination.
  • Sources: Whole grain products, legumes, nuts, seeds, pork.

• B2 (riboflavin): Protection of the nervous system from oxidative stress

  • Function: Riboflavin is involved in energy metabolism and functions as an antioxidant, protecting the nerve cells from damage caused by free radicals. It is also necessary for the metabolism of other vitamins of group B.
  • Influence on the nervous system: Riboflavin plays a role in preventing migraines and maintaining the health of nerve cells. It can also improve cognitive functions.
  • Deficiency symptoms: Inflammation of the lips and cracks in the corners of the mouth (angular stomatitis), inflammation of the tongue (glossitis), dermatitis, photophobia.
  • Sources: Dairy products, eggs, meat, green leafy vegetables, enriched grain products.

• B3 (niacin): Energy and protection for the nervous system

  • Function: Niacin participates in energy metabolism and functions as an antioxidant. He plays a role in the synthesis of neurotransmitters and maintaining the health of nerve cells.
  • Influence on the nervous system: Niacin deficiency can lead to Pellagra, a disease characterized by dermatitis, diarrhea and dementia (three “d”). Niacin is also used in high doses to reduce cholesterol, but this should be done only under the supervision of a doctor.
  • Deficiency symptoms: Dermatitis (especially in areas of skin exposed to the sun), diarrhea, dementia, fatigue, loss of appetite.
  • Sources: Meat, poultry, fish, nuts, seeds, whole grain products, enriched products.

• B5 (pantothenic acid): an indispensable component for the synthesis of neurotransmitters

  • Function: Pantotenic acid is necessary for the synthesis of coenzyme A (COA), which plays a key role in energy metabolism and synthesis of neurotransmitters, including acetylcholine.
  • Influence on the nervous system: Pantotenic acid is important for maintaining the normal function of the nervous system and can affect cognitive functions and stress resistance.
  • Deficiency symptoms: The deficiency of pantothenic acid is rare, but can manifest itself with fatigue, headaches, numbness and tingling in the arms and legs.
  • Sources: Widely distributed in various foods, including meat, poultry, fish, eggs, dairy products, legumes, whole grains, mushrooms.

• B6 (pyridoxine): the key to the synthesis of neurotransmitters and nerves protection

  • Function: Pyridoxine is involved in the synthesis of neurotransmitters, such as serotonin, dopamine and GABA (gamma-aminobatic acid), which regulate mood, sleep and cognitive functions. He also participates in the metabolism of amino acids and the formation of Myelin.
  • Influence on the nervous system: Pyridoxine plays an important role in preventing depression, anxiety and other mood disorders. It can also relieve symptoms of the premenstrual syndrome (PMS). B6 deficiency can lead to peripheral neuropathy.
  • Deficiency symptoms: Depression, irritability, anxiety, insomnia, peripheral neuropathy (numbness and tingling in the arms and legs), convulsions.
  • Sources: Meat, poultry, fish, bananas, avocados, potatoes, enriched grain products.

• B7 (BIOTIN): Support for myelinization and nerve signal

  • Function: Biotin is involved in the metabolism of fats, carbohydrates and proteins. It is also necessary to maintain the health of the skin, hair and nails. Biotin plays a role in transmitting nerve signals and maintaining the myelin shell.
  • Influence on the nervous system: Biotin is important for maintaining the normal function of the nervous system and can affect cognitive functions.
  • Deficiency symptoms: Biotin’s deficiency is rare, but can manifest itself with hair loss, skin rashes, fatigue, depression, numbness and tingling in the arms and legs.
  • Sources: Eggs, liver, nuts, seeds, avocados, salmon, yeast.

• B9 (folic acid): indispensable for the development and protection of the nervous system

  • Function: Folic acid is necessary for dividing cells and DNA synthesis. It plays an important role in the development of the nervous system during pregnancy and maintaining the health of nerve cells throughout life. Folic acid is involved in homocysteine ​​metabolism.
  • Influence on the nervous system: Folic acid deficiency can lead to defects in the nerve tube in the fetus during pregnancy (for example, the back of bifid). In adults, folic acid deficiency can cause depression, fatigue and cognitive disorders.
  • Deficiency symptoms: Fatigue, weakness, irritability, depression, concentration problems, anemia.
  • Sources: Green leafy vegetables, legumes, citrus fruits, enriched grain products.

• B12 (cobalamin): fundamental for myelinization and cognitive functions

  • Function: Cobalamin is necessary to maintain the health of nerve cells and the formation of myelin, fatty substance that surrounds and protects nerve fibers. It also participates in the synthesis of DNA and metabolism of homocysteine.
  • Influence on the nervous system: Cobalamin deficiency can lead to irreversible damage to the nervous system, including peripheral neuropathy, cognitive disorders, depression and psychosis. Vegetarians and vegans are especially at risk of B12 deficiency, since it is mainly found in animal products.
  • Deficiency symptoms: Fatigue, weakness, numbness and tingling in the arms and legs, problems with coordination, depression, problems with memory and concentration, anemia.
  • Sources: Meat, poultry, fish, eggs, dairy products, enriched products.

3. Interaction of group B vitamins: synergistic effect for the nervous system

B vitamins do not work in isolation; They interact with each other, enhancing their effects and providing comprehensive support for the nervous system. For example:

• Homocysteine ​​metabolism: Vitamins B6, B9 and B12 jointly participate in the metabolism of homocysteine, turning it into other beneficial substances. The deficiency of any of these vitamins can lead to an increase in the level of homocysteine, which is associated with an increased risk of cardiovascular and neurodegenerative diseases.
• Energy metabolism: Tiamin (B1), riboflavin (B2), Niacin (B3) and pantotenic acid (B5) play an important role in the transformation of carbohydrates, fats and proteins into the energy necessary for the functioning of nerve cells. The deficiency of any of these vitamins can lead to fatigue and a decrease in cognitive functions.
• Synthesis neurotransmitted: Pyridoxine (B6) and folic acid (B9) are involved in the synthesis of neurotransmitters, such as serotonin, dopamine and gamar, which regulate mood, sleep and cognitive functions.

4. Factors affecting the assimilation of B vitamins

Several factors can affect the assimilation of group B vitamins from food or additives:

• Age: With age, the body’s ability to absorb vitamin B12 decreases, especially due to a decrease in the production of the internal factor in the stomach necessary for its absorption.
• Diet: Diet, poor in food, rich vitamins of group B, can lead to deficiency. Vegetarians and vegans are at risk of deficiency B12.
• Alcohol: Excessive alcohol consumption can violate the absorption of group B vitamins and increase their excretion from the body.
• Some drugs: Some drugs, such as metformin (used to treat diabetes) and proton pump inhibitors (are used to treat heartburn), may violate the assimilation of vitamin B12.
• Diseases of the gastrointestinal tract: Diseases, such as Crohn’s disease, celiac disease and atrophic gastritis, can violate the absorption of vitamins of group B.
• Genetic factors: Some people can have genetic mutations that affect the metabolism of group B vitamins, for example, a mutation of the MthFR gene, which affects the metabolism of folic acid.

5. Symptoms of deficiency of B vitamins B: recognition and action

Symptoms of deficiency of B vitamins can be diverse and often nonspecific, which complicates their diagnosis. It is important to pay attention to the following features:

• Fatigue and weakness: Frequent symptom of deficiency of many vitamins of group B.
• Irritability and depression: B6, B9 and B12 deficiency can affect mood and cause depression and irritability.
• Problems with memory and concentration: B12 deficiency and folic acid can lead to cognitive disorders.
• Numbness and tingling in the arms and legs: B12 and B6 deficiency can cause peripheral neuropathy.
• Muscle weakness: Tiamin deficiency (B1) can lead to muscle weakness.
• Anemia: B12 deficiency and folic acid can cause anemia.
• Dermatitis: Riboflavin deficiency (B2) and niacin (B3) can cause skin rashes.
• Inflammation of the tongue and corners of the mouth: Riboflavin deficiency (B2) can cause glossitis (inflammation of the tongue) and angular stomatitis (cracks in the corners of the mouth).

If you suspect a deficiency of B vitamins, it is important to consult a doctor for diagnosis and treatment. The doctor may prescribe blood tests to determine the level of B vitamins and recommend the appropriate diet or additives.
