How do dietary supplements affect memory and cognitive functions?

I. Cognitive functions: Fundamentals and significance

Cognitive functions cover a wide range of mental processes that allow us to perceive, process, remember and use information. These processes play a decisive role in all aspects of our life, from training and work to social interactions and decision -making. The main cognitive functions include:

  1. Memory: The ability to save and extract information. The memory is divided into several types, including short -term, long -term, episodic (events), semantic (facts) and procedural (skills).

  2. Attention: The ability to concentrate on certain information or task, ignoring distracting factors. Attention includes selective attention, stable attention and divided attention.

  3. Executive functions: A set of higher cognitive processes that allow us to plan, organize, solve problems, make solutions and control our behavior. Executive functions include cognitive flexibility, working memory and brake control.

  4. Language: The ability to understand and use speech, including vocabulary, grammar and understanding of the context.

  5. Visual-spatial skills: The ability to perceive and manipulate visual information, including orientation in space, recognition of objects and understanding of relations between them.

Disorders of cognitive functions can have a significant impact on the quality of life, making it difficult to fulfill everyday tasks, worsening performance and reducing social activity. Age -related changes, stress, lack of sleep, malnutrition and certain diseases can negatively affect cognitive functions.

II. Biologically active additives (dietary supplements): review and classification

Biologically active additives (dietary supplements) are products designed to supplement the diet. They contain one or more food ingredients such as vitamins, minerals, herbs, amino acids or other substances that can have a positive effect on health.

Bades are produced in various forms, including tablets, capsules, powders, liquids and bars. They are not drugs and are not intended for the treatment or prevention of diseases. However, they can be used to maintain health and improve certain functions of the body, including cognitive.

Bades are classified according to various signs, including:

  1. By composition: Vitamins, minerals, plant extracts, amino acids, fatty acids and others.

  2. By purpose: To maintain immunity, improve digestion, increase energy, improve cognitive functions and others.

  3. By the form of release: Tablets, capsules, powders, liquids and others.

It is important to note that dietary supplements are not subject to the same strict test as drugs. Therefore, when choosing dietary supplements, it is necessary to be careful and take into account the reputation of the manufacturer, the composition of the product and possible side effects.

III. Mechanisms of the influence of dietary supplement on cognitive functions

Bades can affect cognitive functions in various ways, including:

  1. Increasing the level of neurotransmitters: Neurotransmitters are chemicals that transmit signals between nerve cells. Some dietary supplements, such as choline and acetyl-L-carnitine, can increase the level of acetylcholine, neurotransmitter, which plays an important role in memory and training. Other dietary supplements, such as L-theanine, can increase the level of gamma-aminomatic acid (GABA), neurotransmitter, which has a calming effect and can improve attention concentration.

  2. Protection of nerve cells from damage: Antioxidants, such as vitamin E, vitamin C and coenzyme Q10, can protect nerve cells from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and contribute to the development of age -related cognitive impairment.

  3. Improving blood circulation in the brain: Some dietary supplements, such as ginkgo biloba, can improve blood circulation in the brain, providing nerve cells with oxygen and nutrients.

  4. Reducing inflammation in the brain: Chronic inflammation in the brain can contribute to the development of cognitive impairment. Some dietary supplements, such as omega-3 fatty acids, have anti-inflammatory properties and can reduce inflammation in the brain.

  5. Support for the health of mitochondria: Mitochondria is cell energy stations. Mitochondria dysfunction can contribute to the development of cognitive impairment. Some dietary supplements, such as Coenzym Q10 and Creatine, can maintain mitochondria health and improve their function.

IV. Review of specific dietary supplements and their impact on cognitive functions

There are many dietary supplements that can potentially have a positive effect on cognitive functions. Below is a review of some of the most studied and promising dietary supplements:

  1. Omega-3 fatty acids: Omega-3 fatty acids, especially non-coosaexenoic acid (DGC), are important components of cell membranes in the brain. They play an important role in the development and functioning of the brain, and also have anti -inflammatory properties. Studies have shown that the use of omega-3 fatty acids can improve memory, attention and executive functions, especially in older people. Sources of omega-3 fatty acids include fish oil, linseed oil and walnuts.

  2. B vitamins B: Group B vitamins, such as vitamin B12, vitamin B6 and folic acid, play an important role in the metabolism of nerve cells and the synthesis of neurotransmitters. B vitamins deficiency can lead to cognitive disorders, such as a deterioration in memory and concentration. Studies have shown that the use of group B vitamins can improve cognitive functions, especially in people with a deficiency of these vitamins.

  3. Ginkgo biloba: Ginkgo biloba is a plant extract that improves blood circulation in the brain and has antioxidant properties. Studies have shown that ginkgo bilobe can improve memory, attention and speed of information processing, especially in older people with age -related cognitive disorders.

  4. Curcumin: Kurkumin is an active ingredient in turmeric, spices with anti -inflammatory and antioxidant properties. Studies have shown that curcumin can improve memory, attention and mood, as well as protect nerve cells from damage.

  5. Caffeine: Caffeine is a stimulant contained in coffee, tea and some other drinks. Caffeine can improve attention, concentration and information processing speed. However, abuse of caffeine can lead to anxiety, insomnia and other side effects.

  6. L-theanine: L -theanine is an amino acid that is contained in tea. L-theanine has a calming effect and can improve concentration and reduce anxiety.

  7. Creatine: Creatine is an amino acid that plays an important role in the energy metabolism of the brain. Studies have shown that the use of creatine can improve memory and executive functions, especially among vegetarians and elderly people.

  8. Phosphateidixine: Phosphatidylserin is a phospholipid, which is an important component of cell membranes in the brain. Studies have shown that the use of phosphatidylserin can improve memory, attention and executive functions, especially in older people with age -related cognitive impairment.

  9. Acetyl-L-carnitine: Acetyl-L-carnitine is an amino acid that plays an important role in the energy metabolism of the brain and the synthesis of acetylcholine. Studies have shown that the use of acetyl-L-carnitine can improve memory, attention and mood, especially in older people with age-related cognitive impairment.

  10. Bakopa Monyeri: Bakop Monieri is a grass that is traditionally used in Ayurvedic medicine to improve memory and cognitive functions. Studies have shown that the use of Monieri bacopa can improve the memory, attention and speed of information processing.
