Fish oil: key information about the popular dietary supplement
This product, which many people found unpleasant since childhood, has become one of the most popular nutritional supplements today. All thanks to omega-3 fatty acids and vitamins A and D, which play an important role in maintaining the health of the body!
Contents of the article:
fish oil contains polyunsaturated fatty epa and DHA acids, which help reduce inflammation, support cardiovascular function and improve skin and hair condition. In addition, vitamin D is important for strong bones and immune defense, while vitamin A promotes normal vision and tissue repair. Regular consumption of fish oil may help improve cognitive function, reduce the risk of depression and maintain a healthy metabolism.
However, it is important to remember that you should consult your doctor before starting to take dietary supplements, especially if you have a chronic illness or are taking other medications. Fish oil is available in various forms – capsules, liquid, which allows you to choose the most convenient method of administration.
Top 5 Health Benefits of Fish Oil
Fish oil contains omega-3s, including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). These components are vital nutrients that support the prevention and treatment of various diseases.
Reducing the risk of cardiovascular disease. Increased levels of omega-3 fatty acids in the blood are strongly associated with a reduced risk of heart problems. Studies show that regularly consuming fish oil products at least twice a week reduces the likelihood of deaths from heart disease. However, recently scientists from the University of Georgia made clarifications: the beneficial effects of fish oil on the heart appear only with a certain genetic background. A study published in PLOS Genetics examined the effects of fish oil on cardiac biomarkers, specifically triglycerides. It was found that the effect of the supplements depended on the genotype: carriers of the AG variant had a decrease in triglycerides, and AA carriers had an increase. However, scientists emphasize the need for further research.
Reduced blood pressure. Numerous scientific studies confirm that taking fish oil helps moderately reduce blood pressure. The benefits are particularly pronounced in people with moderately to severely high blood pressure, while the effects are less noticeable in patients with mild hypertension. In addition, omega-3 fatty acids help improve the elasticity of the vascular wall, which has beneficial effects on blood flow and cardiac function.
Vision support. Research from the Association for Ophthalmic Research has shown that fish oil can slow the progression of age-related macular degeneration, a disease that causes blurred vision and possible blindness. Similarly, scientists at the Harvard Eye Institute found that consuming fish oil alleviated the symptoms of dry eye syndrome, which is associated with insufficient tear production. In addition, DHA is an important structural component of the retina, which helps maintain its normal functioning and reduces the risk of inflammatory processes.
Help with rheumatoid arthritis. Evidence suggests that taking fish oil supplements helps relieve joint pain, morning stiffness and discomfort in patients with rheumatoid arthritis. However, the effect is often moderate and does not always allow one to abandon traditional anti-inflammatory drugs. It is also important to note that omega-3 fatty acids have immunomodulatory properties that help reduce overall inflammation in the body.
Reduced anxiety levels. According to a new study published in Brain, Behavior and Immunity, omega-3 fatty acids may reduce anxiety and reduce inflammation in the body. The experiment involved medical students under constant stress: half of them received omega-3, the other half received a placebo. In the first group, anxiety levels decreased by 20%, and inflammation levels decreased by about 14%. Additional research shows that DHA improves the function of neuronal membranes and promotes the synthesis of neurotransmitters such as serotonin and dopamine, which has a positive effect on emotional well-being and cognitive function.
In the process of making fishmeal, the oil and water are first separated from the carcasses using a centrifuge, after which the oil is purified before storage. At the same time, the quality of fish oil directly depends on the source raw materials and purification technology, since safety is important healthy fats acids and prevention of oxidative processes.
Omega-3: Better from Fish or Supplements?
A 2007 study by Dr. Bill Harris, a recognized expert on omega-3s, confirmed that the body absorbs EPA and DHA equally well from both fish products and special supplements. This is great news for those who don’t eat fish much or don’t like its taste.
At the same time, flaxseed oil cannot replace fish oil. Its main fatty acid, alpha-linolenic acid (ALA), is short-chain, unlike the long-chain EPA and DHA. Although ALA is partially converted to EPA and DHA in the body, the process is extremely inefficient. Therefore, it is important to get both short- and long-chain omega-3 fats to maintain health, as they have different beneficial properties.
What should vegetarians do? They are encouraged to use an algae-based DHA supplement—the body converts some of the DHA into EPA, providing a complex of essential omega-3 fatty acids.
Safe consumption of fish oil
Taking up to 3 grams of fish oil daily in supplement form is considered safe for health. However, you should not increase the dosage on your own – first consult a specialist. Excessive consumption of fish oil can cause a number of side effects:
- Gastrointestinal disorder;
- Loose stools;
- Nausea;
- An unpleasant fishy taste in the mouth and a characteristic “fishy” taste. breath.
In addition, exceeding the dose above 3 grams per day may increase the likelihood of bleeding.
