The benefits of Omega-3: the best dietary supplements for health

Part 1: Foundations of omega-3 fatty acids

What is Omega-3?

Omega -3 fatty acids is a group of polyunsaturated fatty acids that are necessary for human health, but cannot be synthesized by the body independently. This means that they must be obtained from food or additives. They play a decisive role in various physiological processes, from brain to health. The name “omega-3” comes from the chemical structure of the molecule: the first double bond of carbon-uglerod is located on the third carbon from the “omega” of the end of fatty acid.

The main types of omega-3

There are three main types of omega-3 fatty acids, which are most important to human health:

  • Eicopentenic acid (EPA): Basically contained in fatty fish and seaweed. EPA plays an important role in reducing inflammation, maintaining health of the cardiovascular system and improving mood. EPA is the predecessor of eicosanoids, which participate in immune answers and regulation of blood coagulation.

  • Dokosagexenoic acid (DHA): It is also mainly contained in fatty fish and seaweed. DHA is the main structural component of the brain and retina of the eye. It is crucial for the development of the brain, cognitive functions and vision throughout life. DHA also plays a role in maintaining the health of the heart and reducing the risk of developing neurodegenerative diseases.

  • Alpha-linolenic acid (ALA): Contained in plant sources such as linseed seeds, chia seeds, walnuts and some vegetable oils. ALA is the predecessor of EPA and DHA, but the transformation of ALA into these forms in the body is not very effective. Therefore, although ALA is useful fatty acid, the use of fatty fish or additives may be required to obtain enough EPA and DHA.

Omega-3 action mechanisms

Omega-3 fatty acids have many healthy effects on health thanks to several key action mechanisms:

  • Anti -inflammatory action: Omega-3 fatty acids, especially EPA, help reduce inflammation in the body. They compete with omega-6 fatty acids that can contribute to inflammation. Omega-3 reduce the production of inflammatory eicosanoids and cytokines, which can help alleviate the symptoms of various inflammatory diseases.

  • Improving the health of the cardiovascular system: Omega-3 fatty acids have a positive effect on the health of the heart and blood vessels. They help reduce the level of triglycerides, reduce blood clots, reduce blood pressure and improve the function of the endothelium (the inner shell of the vessels).

  • Brain health support: DHA is the main structural component of the brain and plays a decisive role in the development and functioning of the brain. Omega-3 fatty acids can improve cognitive functions, memory and concentration of attention. They can also help protect against neurodegenerative diseases such as Alzheimer’s disease.

  • Improving mood and mental health: Studies show that omega-3 fatty acids can have a positive effect on mood and mental health. They can help alleviate the symptoms of depression, anxiety and other mental disorders. The mechanism of action can be associated with their anti -inflammatory properties and influence on neurotransmitters, such as serotonin and dopamine.

  • Maintaining the health of the eyes: DHA is an important component of the retina. Omega-3 fatty acids can help protect against age-related macular degeneration (VMD) and other eyes of the eyes.

Part 2: Omega-3 benefits for health

Health of the cardiovascular system

Omega-3 fatty acids are one of the most studied nutrients for the health of the cardiovascular system. Numerous studies have shown that they can reduce the risk of cardiovascular diseases and improve the general state of health of the heart.

  • Reducing the level of triglycerides: Omega-3 fatty acids, especially EPA and DHA, effectively reduce the level of triglycerides in the blood. A high level of triglycerides is a risk factor for the development of cardiovascular diseases.

  • Reduced blood pressure: Omega-3 fatty acids can provide moderate, but significant decrease in blood pressure, especially in people with hypertension.

  • Reducing the formation of blood clots: Omega-3 fatty acids have antitrobotic properties, which means that they can help prevent blood clots in the blood vessels. This can reduce the risk of heart attacks and strokes.

  • Improving the function of the endothelium: Omega-3 fatty acids can improve the function of the endothelium, the inner shell of blood vessels. Healthy endothelium plays an important role in maintaining normal blood flow and preventing the development of atherosclerosis.

  • Reduction in risk of arrhythmia: Omega-3 fatty acids can help reduce the risk of arrhythmia (irregular heartbeat), which can be life-threatening.

Brain health and cognitive functions

DHA is the main structural component of the brain and plays a decisive role in the development and functioning of the brain. Omega-3 fatty acids are important for cognitive functions throughout life.

  • Improving memory and learning: Studies show that omega-3 fatty acids can improve memory, training and other cognitive functions. They can be especially useful for older people who have a decrease in cognitive functions.

  • Protection from neurodegenerative diseases: Omega-3 fatty acids can help protect against neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. They can help reduce inflammation in the brain and protect the nerve cells from damage.

  • Improving mood and mental health: Omega-3 fatty acids can have a positive effect on mood and mental health. They can help alleviate the symptoms of depression, anxiety and other mental disorders.

  • Support for brain development in children: Omega-3 fatty acids, especially DHA, are necessary for the development of the brain in infants and children. Adequate consumption of omega-3 during pregnancy and breastfeeding can contribute to the healthy development of the brain and cognitive functions in children.

Inflammatory diseases

Omega-3 fatty acids have anti-inflammatory properties and can be useful for the treatment of various inflammatory diseases.

  • Rheumatoid arthritis: Omega-3 fatty acids can help reduce pain, stiffness and inflammation in the joints of people with rheumatoid arthritis.

  • Inflammatory diseases of the intestine (BCC): Omega-3 fatty acids can help reduce inflammation in the intestines in people with OKK, such as Crohn’s disease and ulcerative colitis.

  • Asthma: Omega-3 fatty acids can help reduce inflammation in the respiratory tract in people with asthma, which can improve the function of the lungs and reduce asthma symptoms.

  • Psoriasis: Omega-3 fatty acids can help reduce skin inflammation and improve symptoms of psoriasis.

Eye health

DHA is an important component of the retina. Omega-3 fatty acids can help protect against diseases of the eyes.

  • Age macular degeneration (VMD): Omega-3 fatty acids can help protect from the ISMD, the main cause of blindness in older people.

  • Dry eye syndrome: Omega-3 fatty acids can help reduce symptoms of dry eye syndrome, such as dryness, irritation and redness of the eyes.

Other health benefits

In addition to the above advantages, omega-3 fatty acids can have other positive effects on health:

  • Improving the health of the skin: Omega-3 fatty acids can help improve skin health, reduce inflammation and moisturize the skin.

  • Support for the immune system: Omega-3 fatty acids can help support the immune system and improve its function.
