1. Introduction: The complexity of the health of the brain and memory

Brain health and preservation of cognitive functions, especially memory, are a complex and multifaceted task. They depend on many factors, including a genetic predisposition, lifestyle, diet, physical activity and environmental impact. A aging, chronic stress, lack of sleep and improper nutrition can have a negative effect on the brain, leading to a decrease in cognitive functions, a worsening memory and increasing the risk of developing neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease.

In recent decades, interest in the role of nutrients, in particular vitamins, has increased significantly in maintaining brain and memory health. Vitamins, being organic compounds necessary for the normal functioning of the body, play a critical role in various metabolic processes, including those that occur in the nervous system. They participate in the synthesis of neurotransmitters, protect neurons from oxidative stress, maintaining the structure and function of cell membranes, as well as in the regulation of immune processes in the brain.

The lack of certain vitamins can lead to serious impaired cognitive functions, such as memory deterioration, a decrease in concentration of attention, a slowdown in information processing and increasing the risk of dementia. On the other hand, adequate consumption of vitamins can help improve cognitive abilities, strengthen memory and protect the brain from age -related changes. However, it is important to understand that the role of vitamins in the health of the brain is not unambiguous and requires further study. It is necessary to take into account the interaction of vitamins with other nutrients, individual characteristics of the body, as well as potential risks associated with excessive consumption of vitamins.

This article is devoted to a detailed examination of the role of various vitamins in maintaining brain and memory health. We will discuss the functions of each vitamin, its effect on cognitive processes, sources of vitamins in nutrition, as well as recommendations for their consumption. In addition, we will consider the interaction of vitamins with other nutrients and factors affecting their assimilation. Finally, we will present a review of the prospects of research and future areas in this area.

2. B vitamins B: Cornial stone of neurological health

B vitamins are a group of eight water -soluble vitamins that play an important role in cell metabolism. They are especially important for the normal functioning of the nervous system and brain health. B vitamins are involved in energy metabolism, synthesis of neurotransmitters, the formation of the myelin shell of nerve fibers and the protection of neurons from damage. The deficiency of any of the vitamins of group B can lead to various neurological and psychiatric disorders, including memory deterioration, depression, irritability, fatigue and peripheral neuropathy.

• 2.1. Vitamin B1 (thiamine): Energy and cognitive function

Tiamin is a cofactor for several enzymes involved in carbohydrate metabolism and energy production. The brain, being an organ with a high level of metabolism, is especially sensitive to thiamine deficiency. Tiamine deficiency can lead to a violation of energy metabolism in the brain, which leads to a deterioration in cognitive functions, such as memory, attention and speed of information processing. The severe deficiency of thiamine can cause Wernik-Korsakov syndrome, characterized by confusion, impaired coordination of movements and memory loss. Sources of thiamine are whole -grain products, legumes, nuts and seeds.

• 2.2. Vitamin B2 (riboflavin): protection against oxidative stress

Riboflavin is a component of two important coofers, Flavmononucleotide (FMN) and Flavideninindininucleotide (FAD), which participate in oxidizing and restoration reactions in the cells. These coenzymes play an important role in the antioxidant protection of the body, helping to neutralize free radicals and protect the cells from damage. The brain is especially subject to oxidative stress, since it has high oxygen consumption and contains a lot of polyunsaturated fatty acids, which are easily oxidized. Riboflavin deficiency can worsen antioxidant protection of the brain and increase the risk of developing neurodegenerative diseases. Riboflavin is found in dairy products, meat, eggs and green leafy vegetables.

• 2.3. Vitamin B3 (niacin): blood supply and neuroprotection

Niacin (nicotinic acid or nicotinamide) is a component of the coofininindinindinicleotide coenzymes (above) and nicotinindinindinindinucleotide phosphate (NDF), which participate in many metabolic processes, including energy metabolism, synthesis of fatty acids and DNA, as well as antioxidant protection. Niacin also plays a role in maintaining the health of blood vessels and improving the blood supply to the brain. It has neuroprotective properties, protecting neurons from damage caused by oxidative stress and inflammation. Niacin deficiency can cause Pellagra, characterized by dermatitis, diarrhea and dementia. Niacin is found in meat, fish, poultry, nuts and grain products.

• 2.4. Vitamin B5 (pantothenic acid): neurotransmitters and cognitive processes

Pantotenic acid is a component of cooferment A (COA), which plays a central role in the metabolism of carbohydrates, fats and proteins. The COA is also involved in the synthesis of acetylcholine, an important neurotransmitter necessary for normal cognitive function, especially memory and training. The deficiency of pantothenic acid is rare, since it is widespread in food products. However, the lack of this vitamin can lead to fatigue, irritability and deterioration of cognitive functions. Pantotenic acid is contained in meat, fish, poultry, eggs, dairy products, fungi and avocados.

These neurotransmitters play an important role in the regulation of mood, sleep, appetite and cognitive functions. A deficiency of pyridoxine can lead to depression, anxiety, irritability, insomnia and memory worsening. It is also necessary for the formation of myelin, a substances that forms a protective shell around the nerve fibers. Pyridoxine is contained in meat, fish, poultry, bananas, avocados and chube.

• 2.6. Vitamin B7 (BIOTIN): Metabolism and brain functions

Biotin is a cofactor for enzymes involved in the metabolism of fatty acids, carbohydrates and amino acids. He also plays a role in the regulation of genes expression and DNA synthesis. Biotin is necessary for the normal functioning of the brain, although its specific role in cognitive processes has not yet been completely studied. Biotin’s deficiency is rare, but can cause neurological symptoms, such as depression, fatigue and cramps. Biotin is found in meat, fish, eggs, nuts and seeds.

• 2.7. Vitamin B9 (folic acid): development and protection of the nervous tube

Folic acid plays an important role in the synthesis of DNA and RNA, as well as in amino acid metabolism. It is especially important for the development of a nervous tube during pregnancy. During pregnancy, deficiency of folic acid can lead to defects of the nerve tube in the fetus, such as spinal splitting (spina bifida) and anencephalus. Folic acid is also important for maintaining brain health in adults. Folic acid deficiency can lead to a deterioration in memory, depression and an increase in the risk of dementia. It is found in green leafy vegetables, legumes and enriched grain products.

• 2.8. Vitamin B12 (cobalamin): myelinization and cognitive function

Cobalamin is necessary for the synthesis of DNA, the formation of red blood cells and maintaining the health of the nervous system. It plays an important role in the formation of the myelin shell of nerve fibers, which provides a quick and effective transmission of nerve impulses. Cobalamin deficiency can lead to demyelization of nerve fibers, which leads to neurological symptoms such as peripheral neuropathy, impaired coordination of movements, memory deterioration and depression. Cobalamine deficiency is especially common among the elderly, since with age the body’s ability to absorb this vitamin from food decreases. Cobalamin is found only in animal products, such as meat, fish, poultry, eggs and dairy products. Vegetarians and vegans are recommended to take cobalamine additives or consume enriched products.

3. Vitamin C: antioxidant protection and collagen

Vitamin C (ascorbic acid) is a powerful antioxidant playing an important role in protecting the body from damage caused by free radicals. Free radicals are unstable molecules that can damage cells, DNA and other important components of the body. Vitamin C is also necessary for the synthesis of collagen, an important protein that provides the structure and elasticity of tissues, including skin, bones, cartilage and blood vessels.

Vitamin D deficiency is associated with an increased risk of developing cognitive impairment, such as memory deterioration, a decrease in concentration and dementia. Studies show that people with a low level of vitamin D in the blood have a higher risk of Alzheimer’s disease. The main source of vitamin D is sunlight, which stimulates the production of vitamin D in the skin. Vitamin D is also contained in some foods such as fatty fish (salmon, tuna, herring), egg yolks and enriched products (milk, yogurt, cereals). In the winter season, when sunlight is not enough, it is recommended to take vitamin D.

5. Vitamin E: Protection of cell membranes from oxidative stress

Vitamin E is a group of fat-soluble antioxidants, the most active of which is alpha-tocopherol. Vitamin E protects cell membranes from damage caused by free radicals, and plays an important role in maintaining brain health.

• 5.1. The antioxidant properties of alpha-tocopherol

Alpha-tocopherol is a powerful antioxidant that neutralizes free radicals and prevents lipid oxidation in cell membranes. This is especially important for neurons, since their membranes are rich in polyunsaturated fatty acids, which are easily oxidized. Vitamin E helps to protect neurons from damage caused by oxidative stress and maintain their normal function.

• 5.2. Influence on the risk of Alzheimer’s disease

Some studies show that adequate consumption of vitamin E can reduce the risk of Alzheimer’s disease. Oxidative stress plays an important role in the pathogenesis of Alzheimer’s disease, and vitamin E can help protect the brain from damage caused by free radicals. However, the results of studies are contradictory, and a further study of this connection is necessary.
