Dietary supplement to improve memory and cognitive functions: detailed review
Section 1: understanding of memory and cognitive functions
Memory and cognitive functions are complex processes that determine our ability to teach, memorize, reason, solve problems and make decisions. With age, as well as under the influence of various factors, such as stress, poor nutrition, lack of sleep and some diseases, these functions can worsen. Therefore, many people turn to biologically active additives (dietary supplements) in the hope of improving their memory, concentration and general cognitive health.
1.1. Memory components:
Memory is not one; It consists of several interconnected systems:
- Sensory memory: Short -term storage of information obtained through the senses (vision, hearing, smell, taste, touch). The fraction of a second lasts.
- Short -term (working) memory: Temporary storage and processing of information necessary to perform current tasks. Limited by the volume and time of storage (several seconds).
- Long -term memory: Storage of information for a long time. Divided into:
- Explicit (declarative) memory: Conscious recalling of facts and events.
- Semantic memory: General knowledge about the world (facts, concepts).
- Episodic memory: Memories of personal events and experiences.
- Implicit (procedural) memory: Unconscious memorization of skills and habits (cycling, playing a musical instrument).
- Explicit (declarative) memory: Conscious recalling of facts and events.
1.2. Key cognitive functions:
In addition to memory, important cognitive functions are:
- Attention: The ability to concentrate on a specific task or stimulus, ignoring distracting factors.
- Language: The ability to understand and use the language for communication.
- Executive functions: The highest cognitive processes, including planning, organization, solution to problems, abstract thinking and cognitive flexibility.
- Visual-spatial perception: The ability to perceive and process information about spatial relationships and orientation in space.
1.3. Factors affecting memory and cognitive functions:
Many factors affect the state of memory and cognitive functions:
- Age: With age, a natural decrease in cognitive functions occurs, including memory and attention.
- Genetics: A genetic predisposition can play a role in the development of cognitive disorders, such as Alzheimer’s disease.
- Life: An unhealthy lifestyle, including poor nutrition, lack of physical activity, smoking and alcohol abuse, can negatively affect cognitive functions.
- Stress: Chronic stress can worsen memory, attention and executive functions.
- Dream: The lack of sleep negatively affects the consolidation of memory and cognitive processes.
- Diseases: Some diseases, such as depression, anxiety disorders, cardiovascular diseases and neurodegenerative diseases (for example, Alzheimer’s disease and Parkinson’s disease) can lead to cognitive disorders.
- Medicines: Some drugs can have side effects that affect memory and cognitive functions.
Section 2: Review of dietary supplements, potentially useful for memory and cognitive functions
There are many dietary supplements that are advertised as tools for improving memory and cognitive functions. It is important to understand that the effectiveness of many of them is not proven convincingly in large, well -controlled clinical research. Before taking any dietary supplements, you need to consult a doctor, especially if you have any diseases or take medications.
2.1. Nootropics:
Nootropics are a class of substances that are believed to improve cognitive functions, especially memory, training and attention.
- Piracetam: One of the first nootropics developed. Presumably improves cognitive functions by increasing blood flow in the brain and neurotransmission. Studies show conflicting results, some confirm a moderate improvement in cognitive functions in older people with cognitive impairment, others do not reveal a significant effect.
- Aniracetam: Piracetam derivative, is considered more powerful. Presumably improves memory, training and attention. Studies are limited, but some preliminary data indicate potential benefits for anxiety and depression.
- Oxiracetam: Another derivative of piracetam. Presumably improves memory, training and concentration. Studies show ambiguous results, some indicate a possible improvement in cognitive functions in older people with cognitive impairment.
- Phenotropil (phonsteratsettes): Russian development. Presumably has stimulating and nootropic effects. It can improve attention, memory and resistance to stress. Studies are limited, some confirm the improvement of cognitive functions and physical performance.
- Noopept: Peptide nootropic. Presumably improves memory, training and concentration, and also has a neuroprotective effect. Studies show potential benefits for cognitive disorders and anxiety.
Important: Noatropics are often not adjusted as strictly as medicines, and their quality can vary. Additional studies are needed to confirm their effectiveness and safety.
2.2. Plant extracts:
- Ginkgo biloba: Extract from ginkgo wood leaves. Presumably improves blood flow in the brain, protects neurons from damage and improves cognitive functions, especially memory and attention. Studies show conflicting results. Some studies confirm a moderate improvement in cognitive functions in older people with cognitive impairment, others do not reveal a significant effect. It can interact with some drugs (for example, anticoagulants).
- Ginseng: An adaptogenic plant, which is believed to improve physical and mental performance, reduces stress and improves cognitive functions. Studies show potential benefits to improve attention, memory and mood. Various types of ginseng (for example, Panax Ginseng, American Ginseng) can have different effects.
- Bacopa Monnieri (Brahmi): Ayurvedic plant, which is believed to improve memory, training and concentration. Studies show potential benefits to improve memory, especially in the elderly. It can cause side effects, such as stomach disorder.
- Curcumin: Active component of turmeric. It has antioxidant and anti -inflammatory properties. Presumably protects neurons from damage and improves cognitive functions. Studies show potential benefits to improve memory and mood. The bioavailability of curcumin can be improved by taking it along with piperin (contained in black pepper).
- Rosemary: It is believed that rosemary improves memory and concentration due to its antioxidant and anti -inflammatory properties. The aroma of rosemary can also have a stimulating effect. Studies are limited, but some data indicate a possible improvement in memory and attention.
- Gotha Cola (Centella asiatica): A plant used in traditional medicine. Presumably improves memory, concentration and mood. Studies show potential benefits to improve cognitive functions and reduce anxiety.
2.3. Vitamins and minerals:
- B vitamins B: Especially vitamins B6, B9 (folic acid) and B12 are important for brain health and cognitive functions. B vitamins deficiency can lead to cognitive disorders, including problems with memory and attention. Vitamin B12 plays an important role in maintaining the myelin shell of the nerve fibers necessary for the normal operation of the nervous system.
- Vitamin D: It is important for brain health and cognitive functions. Vitamin D deficiency is associated with an increased risk of cognitive impairment and dementia.
- Vitamin E: The antioxidant, which is believed to protect neurons from damage. Studies show conflicting results regarding its effect on cognitive functions.
- Omega-3 fatty acids: Contained in fish, fish oil and some vegetable oils (for example, linseed oil). Important to brain health and cognitive functions. DHA (preshase acidic acid) is the main structural component of the brain and plays an important role in maintaining cognitive functions. Studies show potential benefits for improving memory, attention and mood.
- Magnesium: It is important for brain health and cognitive functions. Participates in neurotransmission and protects neurons from damage. Magnesium deficiency can lead to cognitive disorders, anxiety and depression.
- Zinc: It is important for brain health and cognitive functions. Participates in neurotransmission and protects neurons from damage. Zinc deficiency can lead to cognitive disorders, depression and reduction of immunity.
- Iron: It is important for transferring oxygen to the brain. Iron deficiency can lead to fatigue, weakness and cognitive disorders.
2.4. Other dietary supplements:
- Kholin: The predecessor of acetylcholine, neurotransmitter, playing an important role in memory and training. Holina sources include choline bartratrate, CDP choline (Citicoline) and alpha-GPC. Studies show potential benefits for improving memory and cognitive functions, especially in Alzheimer’s disease.
- Creatine: Amino acid, which is believed to improve energy metabolism in the brain. Studies show potential benefits for improving memory, attention and executive functions, especially when performing complex tasks.
- L-theanine: The amino acid contained in tea. Presumably improves concentration, reduces anxiety and promotes relaxation. It is often used in combination with caffeine to improve cognitive functions.
- Acetyl-L-carnitine: The amino acid, which is believed to improve energy metabolism in the brain and protects neurons from damage. Studies show potential benefits for improving memory and cognitive functions, especially in older people with cognitive impairment.
- Phosphateidixine: Phospholipid, which is an important component of cell membranes, especially in the brain. Presumably improves memory, attention and cognitive functions. Studies show potential benefits to improve cognitive functions, especially in the elderly.
- Pycnogenol: Pine bark extract. It has antioxidant and anti -inflammatory properties. Presumably improves blood flow in the brain and protects neurons from damage. Studies show potential benefits for improving memory, attention and cognitive functions.
- PQq (pyrrolochinolinlinhinone): The cooferment, which is believed to support the function of mitochondria and protects neurons from damage. Studies show potential benefits for improving memory and cognitive functions.
- Caffeine: A stimulator that can improve attention, concentration and memory. However, abuse of caffeine can lead to anxiety, insomnia and other side effects.

Section 4: Life and Cognitive Health
It is important to understand that dietary supplements are not a panacea and cannot replace a healthy lifestyle. A healthy lifestyle plays an important role in maintaining cognitive health and can enhance the effect of taking dietary supplements.
4.1. Healthy nutrition:
Balanced diet, rich in fruits, vegetables, whole grain products, low-fat protein and healthy fats (for example, omega-3 fatty acids), important for brain health and cognitive functions. Limit the consumption of processed products, sugar and saturated fats.
4.2. Physical activity:
Regular physical exercises, such as walking, running, swimming or dancing, improve blood flow in the brain, reduce stress and improve cognitive functions. Try to engage in physical exercises at least 150 minutes a week of moderate intensity or 75 minutes a week of high intensity.
4.3. Mental activity:
Regular mental activity, such as reading, solving crosswords, learning a new language or playing a musical instrument, stimulates the brain and helps maintain cognitive functions.
4.4. Sufficient sleep:
A sufficient sleep (7-8 hours a day) is important for consolidation of memory and cognitive processes. Try to go to bed and wake up at the same time every day to maintain a healthy sleep-bonding cycle.
4.5. Stress management:
Chronic stress can worsen memory, attention and executive functions. Find the ways of managing stress, such as meditation, yoga, tai-chi or communication with friends and family.
4.6. Social activity:
Social activity and communication with other people are important for cognitive health. Participate in social events, visit clubs or interest groups, communicate with friends and family.
4.7. Avoid smoking and alcohol abuse:
Smoking and alcohol abuse can negatively affect cognitive functions. Avoid smoking and limit alcohol consumption.
Section 5: Final considerations
Bades can be useful for improving memory and cognitive functions, but they are not replacing a healthy lifestyle and consultation with a doctor. It is important to choose dietary supplements from reliable manufacturers, evaluate scientific evidence, take into account possible side effects and interactions, as well as follow the dosage instructions. The combination of dietary supplements with a healthy lifestyle can help improve memory, attention and general cognitive health.
