Omega-3 dietary supplements for the elderly: health support

I. Introduction: relevance and need

With age, physiological processes in the body undergo significant changes. The effectiveness of organs and systems is reduced, the risk of developing chronic diseases, such as cardiovascular diseases, dementia, arthritis and others, increases. Adequate nutrition and taking biologically active additives (dietary supplements) become important tools for maintaining health and improving the quality of life of older people. Among the dietary supplements, omega-3 polyunsaturated fatty acids (PNSK), which have proven health benefits, deserve special attention. This article examines the role of omega-3 PNSK in maintaining the health of the elderly, analyzes scientific data, describes sources, dosage, potential risks and advantages of taking omega-3 dietary supplements, and also offers practical recommendations for their use.

II. Omega-3 PNSK: Classification and Sources

Omega-3 PNZHK is a family of polyunsaturated fatty acids characterized by the presence of a double bond between the third and fourth carbon atoms in the chain. The most important for human health Omega-3 PNSK includes:

  • Alpha-linolenic acid (Alk): It is the predecessor of other omega-3 PNZHK, but its transformation into eicopascentena (EPC) and non-bosaexen (DGK) acid in the human body is limited.
  • Eicosapentaenic acid (EPA): It has anti-inflammatory properties and plays an important role in maintaining the health of the cardiovascular system.
  • Docosahexaenic acid (DHA): The main structural component of the membranes of brain cells and retina, necessary for the normal functioning of the nervous system and vision.

Sources Omega-3 PNSK:

  • Food sources:
    • Fat fish: Salmon, tuna, sardines, mackerel, herring. Contain significant amounts of EPK and DGK.
    • Vegetable oils: Flue oil, rapeseed oil, soy oil. Contain Alk.
    • Nuts and seeds: Walnuts, flax seeds, chia seeds. Contain Alk.
    • Enriched products: Eggs, milk, yogurts, enriched omega-3 PNZHK.
  • Bad:
    • Fish oil: The most common source of EPK and DGK. Available in the form of capsules, liquid solutions and chewing tablets.
    • Crill oil: Contains EPK and DGK in the form of phospholipids, which can improve their absorption.
    • Algae oil: The vegan source of the DGK obtained from microal -seedlings.
    • Linseed oil: ALK source is available in the form of capsules and liquid solutions.

The choice of the source of Omega-3 PNZHK depends on individual preferences, dietary restrictions (for example, vegetarianism or fish allergies) and health status.

III. Omega-3 PNGK and health of the cardiovascular system in the elderly

Cardiovascular diseases (SVD) are the main cause of mortality in the elderly. Omega-3 PNZHK has a diverse positive effect on the cardiovascular system:

  • Reducing the level of triglycerides: A high level of blood triglycerides is a risk factor for the development of SVD. Omega-3 PNZHK, especially the EPK and DGC, effectively reduce the level of triglycerides. The mechanism of action includes a decrease in the synthesis of triglycerides in the liver and an increase in their disposal.
  • Reduced blood pressure: Omega-3 PNZHK contribute to the expansion of blood vessels and improving their elasticity, which leads to a decrease in blood pressure. This effect is especially important for older people who often observe increased blood pressure.
  • Improving the function of the endothelium: Endothelium is an inner layer of blood vessels, playing a key role in the regulation of vascular tone and preventing blood clots. Omega-3 PNZHK improve the function of the endothelium, reducing the risk of atherosclerosis.
  • Reducing the risk of blood clots: Omega-3 PNZHK has an anti-aggregate effect, reducing the ability of platelets to slip and the formation of blood clots. This effect can be useful for the prevention of heart attacks and strokes.
  • Reducing the risk of sudden heart death: Some studies have shown that the consumption of omega-3 PNSK is associated with a decrease in the risk of sudden heart death, especially in people with cardiovascular diseases.

Clinical studies confirm the positive effect of omega-3 PNSK on the health of the cardiovascular system in the elderly. The meta-analyzes of randomized controlled studies showed that the intake of omega-3 PNSK reduces the risk of developing cardiovascular events, such as myocardial infarction, stroke and death from cardiovascular causes.

IV. Omega-3 PNZHK and cognitive functions in the elderly

The age -related decrease in cognitive functions, including memory, attention and speed of information processing, is a common problem in older people. DGK, the main structural component of membranes of brain cells, plays an important role in maintaining cognitive health.

  • Improving the structure and function of the brain: DGC is necessary for the formation and maintenance of the structure and function of neurons, including synaptic transmission. DGC deficiency can lead to impaired cognitive functions.
  • Reducing the risk of developing dementia and Alzheimer’s disease: Studies show that the consumption of omega-3 PNSK is associated with a decrease in the risk of developing dementia and Alzheimer’s disease. The mechanisms of action include a decrease in inflammation in the brain, an improvement in blood supply to the brain and protect neurons from damage.
  • Improving memory and attention: Some studies have shown that the reception of omega-3 PNSK can improve memory and attention in the elderly, especially in those who experience cognitive impairment.

Although the results of research on the influence of omega-3 PNSK on cognitive functions in older people are ambiguous, many studies support the hypothesis that sufficient consumption of omega-3 PNSK can help maintain cognitive health and reduce the risk of developing neurodegenerative diseases. Further studies are necessary to clarify the optimal dosages and duration of the omega-3 PNSK to achieve the maximum cognitive effect.

V. Omega-3 PNSK and joint health in the elderly

Osteoarthritis is a common joint disease in the elderly, characterized by pain, stiffness and limitation of mobility. Omega-3 PNZHK have anti-inflammatory properties that can help alleviate the symptoms of osteoarthritis.

  • Reducing inflammation in the joints: Omega-3 PNZHK, especially EPC, reduce the production of inflammatory mediators, such as prostaglandins and leukotrienes, in the joints.
  • Reducing pain and stiffness: Clinical studies have shown that the intake of omega-3 PNSK can reduce pain and constraint in the joints in people with osteoarthritis.
  • Improving the function of the joints: Some studies have shown that omega-3 PNZHK can improve the function of the joints and increase the range of movements in people with osteoarthritis.

The mechanism of action of omega-3 PNZHK in osteoarthritis includes a decrease in inflammation, protection of cartilage tissue from destruction and stimulation of collagen synthesis. Although omega-3 PNZHK is not a replacement for the traditional treatment of osteoarthritis, they can be a useful addition to complex therapy.

VI. Omega-3 PNZHK and eye health in older people

Age macular degeneration (VMD) is the main reason for loss of vision in the elderly. DGC is the main structural component of the retina and plays an important role in maintaining vision.

  • Retinal protection from damage: DGC protects the retina from damage caused by oxidative stress and inflammation.
  • Reduction of the risk of developing the VMD: Studies show that the consumption of omega-3 PNSK is associated with a decrease in the risk of development of the VMD.
  • Slow down the progression of the VMD: Some studies have shown that the reception of omega-3 PNSK can slow down the progression of the VMD in people with an existing disease.

The mechanism of action of the omega-3 PNZHK in the VMD includes a decrease in inflammation, an improvement in the blood supply to the retina and the protection of photoreceptors from damage.

VII. Omega-3 PNGK and mental health in the elderly

Depression and other mental disorders are often found in older people. Omega-3 PNSK play an important role in maintaining mental health.

  • Improving mood: Studies show that taking omega-3 PNZHK can improve mood and reduce the symptoms of depression in the elderly.
  • Reduction of risk of depression: Some studies have shown that the consumption of omega-3 PNSK is associated with a decrease in the risk of depression.
  • Improving cognitive functions in people with depression: Omega-3 PNZHK can improve cognitive functions in people with depression, such as memory and attention.

The mechanism of action of the omega-3 PNZHK in depression includes the modulation of neurotransmitters, a decrease in inflammation in the brain and improving the function of neurons.

VIII. Dosages and forms of omega-3 dietary supplements for the elderly

The optimal dosage of omega-3 PNGK for the elderly depends on the state of health, diet and goals of admission. General recommendations:
