Dietary supplements with omega-3 to improve memory: efficiency and dosage

I. Introduction to omega-3 fatty acids

Omega-3 fatty acids are a group of polyunsaturated fatty acids (PNS), which play a crucial role in maintaining human health. They belong to the category of irreplaceable, since the body cannot synthesize them on its own, and they must be obtained from food or additives. The main types of omega-3 fatty acids that are relevant to cognitive functions include:

Eicopentenic acid (EPK, EPA): It has a pronounced anti -inflammatory effect and plays a key role in regulating mood and reducing symptoms of depression.
Dokosagexic acid (DGK, DHA): It is the main structural component of the brain and retina of the eye, necessary for the normal development and functioning of the nervous system, especially for training and memory.
Alpha-linolenic acid (Alk, ALA): Vegetable omega-3 acids, which in the body can partially transform into EPC and DGK, although this process is not very effective.

II. Omega-3 action mechanisms on the brain and memory

Omega-3 fatty acids have a multilateral effect on the brain, contributing to the improvement of cognitive functions, including memory, through various mechanisms:

Structural support of cell membranes: DHC is the main structural component of the cell membranes of the brain, especially in the gray matter. Building in the membranes of neurons, DGC provides their flexibility and fluidity, which improves the transmission of nerve impulses and synaptic plasticity – the ability of the brain to adapt and learn the new. The disadvantage of the DHC can lead to a decrease in this plasticity and the deterioration of cognitive functions.
Neuroprotective action: Omega-3 fatty acids have antioxidant and anti-inflammatory properties that protect the brain from damage caused by free radicals and chronic inflammation. Inflammation plays a significant role in the development of many neurodegenerative diseases, such as Alzheimer’s disease. EPC, in particular, actively suppresses inflammatory processes in the brain, reducing the risk of cognitive impairment.
Improving cerebral circulation: Omega-3 fatty acids contribute to the improvement of blood flow in the brain, providing more effective delivery of oxygen and nutrients to neurons. This is especially important for maintaining the energy metabolism of the brain and preventing ischemic damage.
Regulation of neurotransmitters: Omega-3 fatty acids affect the synthesis and functioning of various neurotransmitters, such as serotonin, dopamine and acetylcholine, which play a key role in the regulation of mood, motivation, attention and memory. For example, increasing the level of serotonin can improve mood and reduce anxiety, which indirectly helps to improve cognitive functions.
Neurogenesis support: Studies show that omega-3 fatty acids can stimulate neurogenesis-the process of the formation of new neurons in the brain, especially in the hippocampus, which is responsible for the formation of new memories. Support for neurogenesis is important for maintaining cognitive health throughout life.

III. Scientific research on the effectiveness of omega-3 to improve memory

Numerous scientific studies studied the effect of omega-3 fatty acids on cognitive functions, including memory, in various age groups and in various conditions.

Research in children and adolescents: Some studies have shown that Omega-3 additives can improve attention, concentration and memory in children and adolescents, especially in those who experience learning difficulties or suffer from attention deficiency and hyperactivity (SDVG). For example, one study showed that taking additives with DGC improved the results of tests for verbal memory in schoolchildren.
Research in adults: Research results in adults are more contradictory. Some studies have shown that taking Omega-3 additives can improve cognitive functions, including memory, in healthy adults, especially in old age. Other studies have not revealed a significant effect. It is important to note that the effectiveness of Omega-3 can depend on individual factors, such as age, genetic predisposition, diet and general health.
Studies in Alzheimer’s disease and other cognitive disorders: Some studies have shown that omega-3 fatty acids can slow down the progression of cognitive impairment in Alzheimer’s disease and other forms of dementia. However, most studies have not revealed a significant improvement in cognitive functions in patients with already developed dementia. Probably, omega-3 is most effective as a preventive measure aimed at maintaining cognitive health in the early stages of neurodegenerative processes.
Systematic reviews and meta -analyzes: Several systematic reviews and meta-analyzes that generalize the results of many studies showed that taking Omega-3 additives can have a small but statistically significant positive effect on cognitive functions, especially in memory and attention, in elderly people with mild cognitive impairment. However, the authors of these reviews note the need to conduct further research with higher methodology standards to confirm these results.

IV. Omega-3 dosage to improve memory

Recommendations for the dosage of omega-3 fatty acids to improve memory vary depending on age, state of health and individual needs. General recommendations are as follows:

General recommendations for adults: Most experts recommend using at least 250-500 mg of EPK and DGK per day to maintain overall health. To improve cognitive functions and memory, a higher dose may be required.
Recommendations for elderly people and people with cognitive disorders: In some studies, doses of up to 1-2 grams of EPK and DGK per day were used to improve cognitive functions in the elderly and people with mild cognitive impairment.
Recommendations for children and adolescents: The dosage of omega-3 for children and adolescents depends on age and weight. It is usually recommended to consume about 100-200 mg of DHK per day to maintain the normal development of the brain and cognitive functions. To improve attention and memory in children with ADHD, higher doses may be required, which should be determined under the supervision of a doctor.
Important factors when determining the dosage: When determining the dosage of Omega-3, it is important to take into account the general state of health, the drugs taken and the presence of contraindications. People with blood coagulation or taking anticoagulants should be careful and consult with the doctor before taking Omega-3 additives.

V. Sources of omega-3 fatty acids

Omega-3 fatty acids can be obtained from various sources, including food and additives.

Food:
- Fat fish: Salmon, mackerel, herring, tuna, sardines – are excellent sources of EPK and DGK. It is recommended to consume fatty fish 2-3 times a week.
- Mollusks: Oysters, mussels, shrimp – contain a small amount of EPK and DGK.
- Vegetable oils: Flaxseed oil, chia oil, perilla oil – contain Alk, which can be partially converted into EPK and DGK.
- Nuts and seeds: Walnuts, chia seeds, flax seeds – contain Alk.
- Enriched products: Some products, such as eggs, milk and yogurts, are enriched with omega-3 fatty acids.
Bad (biologically active additives):
- Fish oil: The most common type of Omega-3 additives containing EPK and DHK. It is important to choose fish oil from reliable manufacturers that guarantee the purity of the product and the absence of heavy metals and other pollutants.
- Krishye fat: Contains EPK and DGK in the form of phospholipids, which, according to some reports, are better absorbed by the body.
- Algae oil: The vegetarian source of the DHC obtained from microal -seedlings.
- Plant additives: Contain Alk obtained from linseed oil or other plant sources.

VI. How to choose high-quality dietary supplements with omega-3

When choosing dietary supplements with Omega-3, it is important to consider the following factors:

Content of EPK and DGK: Pay attention to the amount of EPK and DGK in one portion, and not the total amount of fish oil or kriel fat. The higher the content of the EPC and DGK, the more effective the additive will be.
Omega-3 source: Choose additives from reliable manufacturers that use high-quality sources of Omega-3 and guarantee the purity of the product.
Omega-3 form: Omega-3 can be represented in various forms, such as triglycerides, ethyl ethers and phospholipids. Triglycerides and phospholipids are considered more bioavailable than ethyl ethers.
Availability of quality certificates: Pay attention to the availability of quality certificates from independent organizations, such as NSF International or USP Verified. These certificates confirm that the product meets the stated requirements for cleanliness, efficiency and safety.
Customer reviews: Read the reviews of other buyers to find out about their experience of using the additives.

VII. Side effects and contraindications

Omega-3 fatty acids are usually safe for most people when consumed in recommended doses. However, in some cases, side effects can occur, such as:

Digestive disorders: Nausea, diarrhea, bloating, belching. These side effects often occur when using high doses of Omega-3.
Fish taste in the mouth: It can occur after taking fish oil supplements.
Increasing the risk of bleeding: Omega-3 fatty acids can dilute blood, so people with blood coagulation or taking anticoagulants should be careful and consult with the doctor before taking Omega-3 additives.
Allergic reactions: Rarely, but allergic reactions to fish or other ingredients in the additive are possible.

Contraindications to the reception of omega-3 fatty acids include:

Allergy to fish or other ingredients in the composition of the additive.
Reception of anticoagulants (warfarin, clopidogrel, etc.) without consulting a doctor.
Blood coagulation disorders.

VIII. Omega-3 and cognitive functions at different stages of life

The influence of omega-3 on cognitive functions can vary depending on the age and stage of development.

Prenatal period and early childhood: DGC plays a crucial role in the development of the brain and the nervous system of the fetus and the newborn. Sufficient consumption of DHC with pregnant and nursing women is necessary for the normal development of cognitive functions in a child.
Childhood and adolescence: Omega-3 fatty acids are necessary to maintain attention, concentration and memory in children and adolescents. Omega-3 additives can be useful for children with ADHD and other learning difficulties.
Adult age: Omega-3 fatty acids contribute to maintaining cognitive health and reducing the risk of cognitive disorders in the middle age.
Elderly age: Omega-3 fatty acids can slow down the progression of cognitive impairment and improve memory and attention in elderly people with mild cognitive impairment.

IX. Omega-3 interaction with other nutrients and drugs

Omega-3 fatty acids can interact with other nutrients and drugs.

Vitamin E: Vitamin E is an antioxidant that can protect omega-3 fatty acids from oxidation. Some Omega-3 additives contain vitamin E to improve their stability.
Anticoagulants: Omega-3 fatty acids can enhance the effect of anticoagulants, such as warfarin, increasing the risk of bleeding. People taking anticoagulants should consult a doctor before taking Omega-3 additives.
Nonsteroidal anti -inflammatory drugs (NSAIDs): Omega-3 fatty acids can enhance the anti-inflammatory effect of NSAIDs.
Medicines for reducing blood pressure: Omega-3 fatty acids can reduce blood pressure, which may require adjustments to the dose of drugs to reduce blood pressure.

X. Alternative approaches to improving memory

In addition to taking Omega-3 additives, there are other strategies that can help improve memory and cognitive functions.

Healthy nutrition: The use of a diverse and balanced diet rich in fruits, vegetables, whole grain products and low -fat sources of protein is important for maintaining cognitive health.
Regular physical exercises: Physical activity helps to improve blood circulation in the brain and stimulates neurogenesis.
Mental activity: Regular performance of exercises for the brain, such as reading, solving crosswords, learning new languages or playing chess, helps maintain cognitive functions.
Sufficient sleep: The lack of sleep can negatively affect memory and concentration. It is important to sleep enough time (7-8 hours a day) to maintain the optimal cognitive function.
Stress management: Chronic stress can damage the brain and worsen cognitive functions. It is important to learn how to effectively manage stress using methods such as meditation, yoga or breathing exercises.
Social activity: Maintaining social ties and participation in public life can help improve cognitive functions and reduce the risk of dementia.

In conclusion, omega-3 fatty acids play an important role in maintaining cognitive health and can help improve memory, especially in older people with light cognitive impairment. However, the effectiveness of Omega-3 can depend on individual factors, and to achieve optimal results, it is necessary to combine the reception of the Omega-3 additives with a healthy lifestyle and other strategies aimed at maintaining cognitive health. It is important to consult a doctor before taking Omega-3 additives, especially in the presence of any diseases or taking drugs.
