B vitamins for older people: complete guidance for maintaining health and life activity
I. The role of group B vitamins in the body of the elderly: necessity and significance
B vitamins are a complex of eight water -soluble vitamins, each of which plays a unique, but interconnected role in maintaining optimal health. With age, physiological changes, such as a decrease in the absorption of nutrients, chronic diseases and medication, can lead to a deficiency of group B vitamins, which, in turn, negatively affects various aspects of the health of older people. Understanding the role of each vitamin and the consequences of its lack is crucial for the timely prevention and maintenance of high quality life.
IA General functions of B vitamins B:
- Energy metabolism: Vitamins B are necessary for turning food into energy, maintaining activity and vitality. They participate in the metabolism of carbohydrates, fats and proteins.
- Nervous system health: Vitamins B support the normal functioning of the nervous system, the transmission of nerve impulses, cognitive functions and emotional well -being.
- Blood cell formation: Some vitamins B (especially B9 and B12) are extremely important for the formation of healthy red blood cells, preventing anemia and providing tissue oxygen.
- Synthesis DNA and RNA: B vitamins are involved in the synthesis and reparations of DNA and RNA, which is important for cell growth and division.
- Support for the immune system: B vitamins play a role in maintaining the optimal function of the immune system, helping the body fight infections.
IB age -related changes affecting the assimilation of B vitamins B:
- Substance reduction: With age, the production of gastric acid decreases (hypochlorhydria), which complicates the absorption of some vitamins, especially vitamin B12.
- Chronic diseases: Diseases of the gastrointestinal tract (atrophic gastritis, Crohn’s disease, ulcerative colitis), renal failure and other chronic conditions can disrupt the absorption and metabolism of vitamins B.
- Medication: Some drugs, such as metformin (for the treatment of diabetes), proton pump inhibitors (to reduce the acidity of the stomach) and some antibiotics, can reduce the level of group B vitamins in the body.
- Limited diet: Older people often have a limited diet due to problems with chewing, swallowing, reducing appetite or financial difficulties. This can lead to insufficient consumption of B vitamins B.
- Reducing the function of the liver and kidneys: With age, the function of the liver and kidneys, which play an important role in metabolism and the excretion of vitamins, may decrease, which affects their level in the body.
- Inflammatory processes: Inflammation, which often accompanies aging (Inflammaging), can increase the body’s need for vitamins of group B, especially in vitamin B6, which is necessary to combat inflammation.

It is recommended to use vitamin B12 in the form of additives (for example, cyanocobalamin or methylcobalamin) or enriched products, as they are better absorbed. In some cases, vitamin B12 injections may require.
III. Diagnosis of deficiency of group B vitamins in the elderly:
- Blood test: A blood test is the main method of diagnosing a deficiency of B vitamins B. The levels of vitamins B12, folate, vitamin B6 and homocysteine are evaluated. The low level of vitamins and a high level of homocysteine may indicate a deficit.
- Symptoms Assessment: The doctor evaluates the symptoms of the patient, such as fatigue, weakness, memory problems, numbness and tingling in the arms and legs, and compares them with possible signs of deficiency of vitamins of group B.
- Medical history: The doctor collects information about the patient’s medical history, including the presence of chronic diseases, drugs taken and nutritional characteristics, which can affect the level of B vitamins B.
- Physical examination: The doctor conducts a physical examination to identify signs of deficiency of B vitamins, such as inflammation of the tongue, dermatitis or neurological disorders.
IV. Strategies for the prevention and treatment of deficiency of group B vitamins in the elderly:
- Balanced nutrition: It is recommended to adhere to a balanced diet rich in products containing B vitamins such as meat, fish, eggs, dairy products, whole grain products, legumes, vegetables and fruits.
- Enriched products: The use of enriched products, such as enriched cereals and vegetable milk, can help increase the consumption of vitamins of group B.
- Vitamin additives: If necessary, the doctor may prescribe vitamin additives of group B. It is important to take additives in accordance with the doctor’s recommendations and not exceed the recommended dose. It is recommended to choose additives with bio-access forms of vitamins, such as methylcobalamin (B12) and 5-methyltetrahydrofolat (folat).
- Vitamin B12 injections: In case of violation of the absorption of vitamin B12 (for example, with pernicious anemia), vitamin B12 injections may be required.
- Correction of concomitant diseases: Treatment of concomitant diseases, such as atrophic gastritis or Crohn’s disease, can improve the absorption of group B. vitamins.
- Change in drug therapy: If necessary, the doctor can adjust drug therapy to reduce the effect of drugs on the level of vitamins of group B.
- Regular monitoring: Regular monitoring of the level of group B vitamins in the blood allows you to timely identify and adjust the deficiency.
- Consultation with a doctor: Before taking vitamin additives or a change in the diet, it is recommended to consult a doctor to determine the optimal strategy for the prevention and treatment of group B vitamins deficiency.
V. The interaction of group B vitamins with other nutrients and drugs:
- Folate and Vitamin B12: The deficiency of one of these vitamins can mask the shortage of the other. With a deficiency of a folate, it is first necessary to exclude the deficiency of vitamin B12, since taking a folate with a deficiency of vitamin B12 can aggravate neurological problems.
- Vitamin B6 and Levodopa: Vitamin B6 can reduce the effectiveness of levodopa, drugs for the treatment of Parkinson’s disease. Therefore, patients taking Levodopa are not recommended to take high doses of vitamin B6.
- Alcohol: Excessive alcohol consumption can reduce the level of vitamins of group B, especially thiamine, pyridoxine and folate.
- Proton pump inhibitors (IPP): A long -term receipt of IPP can reduce the absorption of vitamin B12.
- Metformin: Metformin, a medicine for the treatment of diabetes, can reduce the absorption of vitamin B12.
- Vitamin C: Vitamin C can improve the absorption of some vitamins of group B, such as thiamine.
- Zinc: Zinc is necessary for the normal metabolism of vitamin B6.
VI. The role of intestinal microbiots in the metabolism of B vitamins B:
The intestinal microbiota plays an important role in the synthesis and assimilation of some B vitamins, in particular, biotin and vitamin K. Healthy and various intestinal microbiota contributes to the optimal metabolism of group B vitamins and maintaining general health.
- Probiotics and prebiotics: Taking probiotics (beneficial bacteria) and prebiotics (food for beneficial bacteria) can help improve the composition of intestinal microbiots and increase the level of vitamins of group B. Probiotic products include yogurt, kefir, sauerkraut and other fermented products. Prebiotic products include onions, garlic, bananas, artichokes and asparagus.
VII. Modern research on group B vitamins and the health of the elderly:
Constant studies are being conducted that study the role of group B vitamins in maintaining the health of the elderly. Some of the promising fields of research include:
- The influence of group B vitamins on cognitive functions: Studies continue to study the influence of group B vitamins as a memory, concentration and risk of dementia.
