Omega-3 and heart health: dosage and advantages

I. The fundamental aspects of omega-3 fatty acids

  1. Definition and classification of omega-3 fatty acids: Omega-3 fatty acids are a family of polyunsaturated fatty acids (PNS), characterized by the presence of the first double bond between the third and fourth carbon atoms from the methyl end (omega-cowl) molecule of fatty acid. They are indispensable fatty acids, since the human body is not able to synthesize them in sufficient quantities, and they should come with food or additives. The main types of omega-3 fatty acids, which are important to human health, include:

    • Alpha-linolenic acid (Alk): Vegetable omega-3 fatty acid contained in sources such as linseed seeds, walnuts, chia seeds and hemp oil. ALK is the precursor of the Eikosapendenova (EPK) and Dokosagexen (DGC) acids, but its conversion into these acids in the human body is limited.

    • Eicosapentaenic acid (EPA): Sea omega-3 fatty acid, mainly contained in fatty fish (salmon, mackerel, herring, sardines) and algae. EPC plays an important role in reducing inflammation, improving mood and maintaining health of the cardiovascular system.

    • Docosahexaenic acid (DHA): Also sea omega-3 fatty acid, widespread in fatty fish and algae. DGC is the main structural component of the brain, retina and sperm. It is necessary for the normal development of the brain and vision, as well as to maintain cognitive functions throughout life.

  2. The mechanisms of the action of omega-3 fatty acids on the body: Omega-3 fatty acids have a multifaceted effect on the body, affecting various physiological processes. The main action mechanisms include:

    • Anti -inflammatory action: EPK and DGC compete with arachidonic acid (omega-6 fatty acid) in the process of eicosanoid formation, such as prostaglandins and leukotrienes. EPK and DGC lead to the formation of less inflammatory eicosanoids, which helps to reduce inflammation in the body.

    • Influence on a lipid profile: Omega-3 fatty acids help to reduce the level of triglycerides in the blood, increase the level of “good” cholesterol (HDL) and, in some cases, a slight decrease in the level of “bad” cholesterol (LDL).

    • Regulation of blood pressure: Omega-3 fatty acids can help reduce blood pressure by improving the function of the endothelium (internal lining of blood vessels) and reducing vascular resistance.

    • Antiarrhythmic action: Omega-3 fatty acids have a stabilizing effect on the electrical activity of the heart, which can reduce the risk of arrhythmias, especially in people with cardiovascular diseases.

    • Improving the function of the endothelium: Omega-3 fatty acids stimulate the production of nitrogen oxide (No), which is an important vasodilator that expands blood vessels and improves blood flow.

    • The effect on blood coagulation: Omega-3 fatty acids can have a moderate antitrombotic effect, reducing platelet aggregation and the risk of blood clots.

  3. Sources of omega-3 fatty acids in the diet: Obtaining a sufficient amount of omega-3 fatty acids with food is an important condition for maintaining health. The main dietary sources of omega-3 fatty acids include:

    • Fat fish: Salmon, mackerel, herring, sardins, tuna, trout are rich sources of EPK and DGK. It is recommended to consume fatty fish at least twice a week.

    • Vegetable oils: Flaxseed oil, chia oil, hemp oil – contain Alk. It is important to consider that the conversion of the Alc into the EPC and the DGC in the body is limited.

    • Nuts and seeds: Walnuts, chia seeds, flax seeds, hemp seeds – contain Alk.

    • Enriched products: Some foods, such as eggs, milk and yogurt, are enriched with omega-3 fatty acids.

    • Supplements: Fish oil, crill oil, algae oil – contain EPK and DGK. Addments are a convenient way to obtain a sufficient amount of omega-3 fatty acids, especially for people who do not consume enough fat fish.

II. The role of omega-3 in the prevention and treatment of cardiovascular diseases

  1. The influence of omega-3 on risk factors for cardiovascular diseases: Omega-3 fatty acids have a positive effect on a number of risk factors for cardiovascular diseases, including:

    • Reducing the level of triglycerides: The high level of blood triglycerides is an independent risk factor for cardiovascular diseases. Omega-3 fatty acids, especially the EPK and DGC, effectively reduce the level of triglycerides, reducing their production in the liver and accelerating their splitting. The dosage necessary for a significant decrease in triglycerides is usually 2-4 grams of EPK and DGK per day.

    • Improving the level of “good” cholesterol (HDL): The low level of HDL is a risk factor for cardiovascular diseases. Omega-3 fatty acids can slightly increase the level of HDL, although the effect is usually not as pronounced as a decrease in triglycerides.

    • Reduced blood pressure: High blood pressure is the main risk factor in cardiovascular diseases. Omega-3 fatty acids contribute to a decrease in blood pressure, especially in people with hypertension. The mechanism of action is associated with an improvement in the function of the endothelium and a decrease in vascular resistance. The dosage necessary to reduce blood pressure is usually 2-3 grams of EPK and DGK per day.

    • Improving the function of the endothelium: The dysfunction of the endothelium is an early sign of the development of atherosclerosis. Omega-3 fatty acids improve the function of the endothelium, stimulating the production of nitrogen oxide (NO), which is a powerful vasodilator.

    • Reduced inflammation: Chronic inflammation plays an important role in the development of atherosclerosis. Omega-3 fatty acids have anti-inflammatory effects, reducing the level of inflammatory markers, such as C-reactive protein (SRB) and Interleukin-6 (IL-6).

  2. Omega-3 and atherosclerosis: Atherosclerosis is the process of plaque formation in arteries, leading to narrowing of blood vessels and increasing the risk of a heart attack and stroke. Omega-3 fatty acids have a protective effect against atherosclerosis due to several mechanisms:

    • Reducing the formation of atherosclerotic plaques: Omega-3 fatty acids can reduce the adhesion of monocytes (type of leukocytes) to endothelium, which is an important step in the formation of atherosclerotic plaques.

    • Stabilization of atherosclerotic plaques: Omega-3 fatty acids can contribute to the stabilization of existing atherosclerotic plaques, reducing the risk of their rupture and thrombosis.

    • LTNP oxidation decrease: Oxidized LDLs play an important role in the development of atherosclerosis. Omega-3 fatty acids can reduce the oxidation of LDL, reducing their atherogenic potential.

  3. Omega-3 and coronary heart disease (coronary artery disease): IBS is a condition in which the blood supply to the heart muscle is limited, which can lead to angina pectoris (chest pain) and a heart attack. Omega-3 fatty acids have a positive effect on coronary heart disease:

    • Reduction of the risk of a heart attack: Studies show that the use of omega-3 fatty acids is associated with a decrease in the risk of heart attack, especially sudden heart death.

    • Improving the function of the heart: Omega-3 fatty acids can improve the contractile function of the heart and reduce the risk of heart failure.

    • Risk reduction of arrhythmias: Omega-3 fatty acids have an antiarrhythmic effect, stabilizing the electrical activity of the heart and reducing the risk of dangerous arrhythmias, such as ventricular tachycardia and ventricular fibrillation.

  4. Omega-3 and heart failure: Heart failure is a condition in which the heart cannot effectively pump blood to meet the needs of the body. Omega-3 fatty acids can have a favorable effect on heart failure:

    • Improving the function of the heart: Omega-3 fatty acids can improve the contractile function of the heart and reduce the risk of progression of heart failure.

    • Reduction of the risk of hospitalizations: Studies show that the use of omega-3 fatty acids is associated with a decrease in the risk of hospitalization for heart failure.

    • Reduction of the risk of mortality: Omega-3 fatty acids can reduce the risk of mortality in patients with heart failure.

  5. Omega-3 and arterial hypertension: Arterial hypertension (high blood pressure) is the main risk factor for cardiovascular diseases. Omega-3 fatty acids can help reduce blood pressure:

    • Decrease in systolic and diastolic blood pressure: Omega-3 fatty acids, especially EPK and DHC, can reduce both systolic (upper) and diastolic (lower) blood pressure.

    • Improving the function of the endothelium: Omega-3 fatty acids improve the function of the endothelium, stimulating the production of nitrogen oxide (NO), which is a powerful vasodilator.

    • Reducing vascular resistance: Omega-3 fatty acids can reduce vascular resistance, facilitating the functioning of the heart on blood pumping.

III. Omega-3 dosage for heart health

  1. General recommendations for the dosage of Omega-3: General recommendations for the dosage of omega-3 fatty acids to maintain heart health vary depending on individual needs and the presence of cardiovascular diseases.

    • Prevention of cardiovascular diseases: For the prevention of cardiovascular diseases, it is recommended to use at least 250-500 mg of EPK and DGK per day. This amount can be achieved by using fatty fish at least twice a week.

    • Treatment of hypertriglyceridemia: To reduce the level of triglycerides, a higher dosage of omega-3 fatty acids, usually 2-4 grams of EPK and DGK per day, may be required. It is important to consult a doctor before starting taking high doses of omega-3 fatty acids.

    • Treatment of arterial hypertension: To reduce blood pressure, it is recommended to use 2-3 grams of EPK and DGK per day.

    • Heart failure: For patients with heart failure, it is recommended to use 1-2 grams of EPK and DGK per day.

  2. The influence of various factors on the need for omega-3: The need for omega-3 fatty acids can vary depending on various factors, such as:

    • Age: The need for omega-3 fatty acids can be higher in older people, since their ability to synthesize EPK and DGC from the ALK can be reduced.
