Omega-3 for older people: choosing the best additives

I. Omega-3 fatty acids: basics and meaning

  1. Definition and classification: Omega-3 fatty acids is a family of polyunsaturated fatty acids (PNS) necessary for the normal functioning of the human body. They are classified according to the chemical structure, namely the location of the first double bond from the methyl (omega-) end of the molecule. The main omega-3 fatty acids representing interest to human health include:

    • Alpha-linolenic acid (Alk): Vegetable omega-3 contained in the seeds of flax, chia, hemp, walnuts and some vegetable oils. Alk is the predecessor of the EPK and DGK, but its transformation into these acids in the human body is limited.

    • Eicosapentaenic acid (EPA): Sea omega-3, mainly contained in fatty fish and seafood. EPC plays a key role in reducing inflammation, supporting heart health and improving mood.

    • Docosahexaenic acid (DHA): Sea Omega-3, also contained in fatty fish and seafood. DGC is the main structural component of the brain and retina of the eye, playing an important role in cognitive functions and vision.

  2. Action mechanisms: Omega-3 fatty acids affect the body through several mechanisms:

    • Anti -inflammatory action: EPK and DGK are metabolized into eicosanoids, such as prostaglandins and leukotrienes, which have anti -inflammatory properties. They compete with omega-6 fatty acids in the synthesis of eicosanoids, reducing the production of pro-inflammatory substances.

    • Influence on cell membranes: DGC is an important component of cell membranes, especially in the brain and retina. The inclusion of DHC in the membranes increases their fluidity and flexibility, which improves cell alarm and function.

    • Influence on a lipid profile: Omega-3 fatty acids can reduce the level of triglycerides in the blood, which is a risk factor for cardiovascular diseases. They can also increase the level of “good” cholesterol (HDL).

    • Neuroprotective action: DGC plays an important role in the development and maintenance of brain health. It supports synaptic transmission, neuroplasticity and protects neurons from damage.

  3. The need for omega-3 in the elderly: With age, the body undergoes a number of changes that can increase the need for omega-3 fatty acids.

    • Reducing the effectiveness of alk transformation: The body’s ability to transform Alc into EPC and DGC decreases with age. This makes the consumption of EPC and DGC from sea springs or additives especially important for the elderly.

    • Age -related changes in the brain: The age -related decrease in cognitive functions and the risk of developing neurodegenerative diseases, such as Alzheimer’s disease, increases with age. DGC plays an important role in maintaining brain health and can help slow down these processes.

    • Increasing the risk of cardiovascular diseases: The risk of developing cardiovascular diseases, such as coronary heart disease and stroke, increases significantly with age. Omega-3 fatty acids have a favorable effect on the cardiovascular system, reducing the risk of these diseases.

    • Inflammation and immune function: Chronic inflammation of low severity, known as “Inflammage”, is a common phenomenon in the elderly and is associated with various age -related diseases. Omega-3 fatty acids have anti-inflammatory properties and can help reduce the level of inflammation in the body. Age-related changes in the immune system (immunostation) can also be mitigated by Omega-3 consumption.

    • Joint health: Osteoarthritis, a common joint disease in the elderly, is characterized by pain and inflammation. Omega-3 fatty acids can help reduce inflammation in the joints and alleviate the symptoms of osteoarthritis.

  4. Recommended daily dose: Recommendations on the daily consumption of omega-3 fatty acids vary depending on age, state of health and individual needs. However, general recommendations for adults, including the elderly, make up:

    • Alk: For adult men, about 1.6 grams per day are recommended, and for women – about 1.1 grams per day. However, taking into account the low efficiency of the transformation of the Alc into the EPC and the DGC, it is recommended to increase the consumption of EPC and DHC from other sources.

    • EPA and DHK: The general recommendation is 250-500 mg of EPK and DGK per day to maintain overall health. For people with cardiovascular diseases or other diseases requiring higher doses, it may take 1-4 grams per day under the supervision of a doctor. It is important to consider that the upper permissible limit of the Omega-3 consumption is not set, but high doses (more than 3 grams per day) can increase the risk of bleeding and other side effects.

II. Sources of omega-3 fatty acids

  1. Food sources:

    • Fat fish: The best source of EPK and DGK is oily fish, such as salmon, tuna, mackerel, herring and sardines. It is recommended to consume fatty fish at least twice a week. It is important to choose fish caught in environmentally friendly areas in order to minimize the effects of pollutants, such as mercury.

    • Seafood: Other seafood, such as shrimp, crabs and mussels, also contain omega-3 fatty acids, although in smaller quantities than fatty fish.

    • Plant sources: Alk is contained in flax, chia, hemp, walnuts and some vegetable oils (linseed, hemp, soybean). However, as mentioned earlier, the transformation of the ALK into EPC and the DGC in the human body is limited.

    • Enriched products: Some products, such as eggs, milk and yogurt, are enriched with omega-3 fatty acids. Usually they are enriched with Alk, but some manufacturers add EPK and DGK.

  2. Omega-3 supplements: For many people, especially for those who do not use a sufficient amount of fat fish or have certain medical indications, Omega-3 additives are a convenient and effective way to increase the consumption of these important fatty acids.

    • Fish oil: The most common type of Omega-3 additive. Fish oil is obtained from oily fish, such as salmon, tuna, mackerel and herring. The content of the EPC and DGC in fish oil can vary depending on the type of fish and processing process. It is important to choose high -quality fish oil, which has undergone cleaning of pollutants, such as mercury, PCD and dioxins.

    • Crill oil: Croil oil is obtained from small crustaceans living in the Antarctic. Omega-3 fatty acids in the oil oil are in the form of phospholipids, which is believed to improve their absorption. Croil oil also contains antioxidant Astaxantin. However, Krill oil, as a rule, is more expensive than fish oil and may contain less EPC and DGK for a portion. In addition, it is worth taking into account the ethical aspects of the catch of Kril, since Kril is an important link in the Antarctic food chain.

    • Algae oil: Suitable for vegetarians and vegans, as it is obtained from microal -seeds, which are the primary source of EPK and DGC in the sea food chain. Algae oil contains only DGK, or DHK and EPK. This is an environmentally stable option that does not contribute to excessive fish catch.

    • Concentrated omega-3 additives: These additives contain a higher concentration of EPK and DGC than ordinary fish oil. They can be useful for people who require a higher dose of Omega-3.

  3. Factors affecting the choice of source:

    • Dietary preferences: Vegetarians and vegans should choose algae oil or enriched products.

    • Allergies: People with allergies to fish or seafood should avoid fish oil and croil oil.

    • Price: Fish oil, as a rule, is cheaper than oil and algae oil.

    • Absorption: Krill oil, it is claimed, is better absorbed than fish oil, due to the omega-3 content in the form of phospholipids. However, this difference in digestibility can be insignificant for most people.

    • Environmental considerations: Algae oil is a more environmentally friendly option than fish oil and krill oil. When choosing fish oil, it is important to give preference to products obtained from stable fish farms.

III. Criteria for choosing high-quality additives omega-3

  1. Content of EPK and DGK: It is important to pay attention to the actual content of the EPC and DGK in addition, and not just the total amount of fish oil or oil. The percentage of the EPC and DGK should be indicated on the label. It is advisable to choose additives with a higher concentration of EPK and DGC to take fewer capsules to achieve the required dose.

  2. Omega-3 form: Omega-3 fatty acids in additions can be represented in different forms:

    • Triglyceride (tg): The natural form of Omega-3, which is better absorbed by the body.

    • Ethyluster (ee): The cheaper form of omega-3, which is less stable and worse absorbed. Many manufacturers process ethylages back into triglycerides to improve their digestibility.

    • Phospholippide: Omega-3 in the form of phospholipids contained in the oil of the Crill, it is claimed, are better absorbed.

    • Free fatty acids (FFA): This form of Omega-3 has a high degree of digestibility.

    It is preferable to choose additives containing omega-3 in the form of triglycerides, phospholipids or free fatty acids.

  3. Cleanliness and safety: It is important to choose additives that have been tested for pollutants, such as mercury, PHD, dioxins and other heavy metals. Look for additives certified by third -party organizations such as NSF International, USP (United States Pharmacopeia) or IFOS (International Fish Oil Standards). These organizations conduct independent checks of products for compliance with quality and safety standards.

  4. Freshness: Omega-3 fatty acids are subject to oxidation, which can reduce their effectiveness and lead to the formation of harmful substances. Signs of oxidation include an unpleasant smell and taste of fish. Choose additives with antioxidants added, such as vitamin E, to prevent oxidation. It is also important to store additives in a cool, dark place in order to maintain their freshness. Pay attention to the date of manufacture and expiration date.

  5. Certification by third -party organizations: Certification by third -party organizations guarantees that the product was tested on compliance with the declared content of the EPK and DGK, the purity and lack of pollutants.

  6. Manufacturer: Choose additives from well -known and reliable manufacturers that adhere to strict quality standards. Read consumer reviews and study the manufacturer’s reputation.

  7. Lack of artificial additives: Avoid additives containing artificial dyes, flavors and preservatives.
