Omega-3 fatty acids

Most Americans consume too much of the omega-6 fatty acids found in meat and most vegetable oils, but suffer from a relative deficiency in the omega-6 fatty acids found in meat and most vegetable oils. Omega 3 — and it is linked to an increased risk of heart disease and also about 60 other diseases, including cancer, arthritis, stroke, hypertension, skin diseases and diabetes.

Long-chain omega-3 fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) , are especially important for health. They are found in fish, especially cold water fish such as salmon, mackerel, herring and halibut. Although the body can convert alpha-linolenic acid, a short-chain omega-3 fatty acid found in flaxseed oil, into other omega-3 acids, but fish oils They are a much more efficient way to get them. Furthermore, there is evidence that many people have difficulty converting alpha-linolenic acid to EPA and DHA.

Why are long-chain omega-3 fatty acids so important?

The answer has to do with the function of these fatty compounds in cell membranes. Dietary deficiency of omega-3 fatty acids, in particular EPA and in DHA , leads to a change in the composition of the cell membranes. Cells with an unhealthy membrane lose their ability to retain water, essential nutrients and electrolytes. They also lose their ability to communicate with other cells and are unaffected by hormones designed to regulate their activity. They simply do not function as required.

Dysfunction of cell membranes is an essential factor in the development of almost all chronic diseases, in particular cancer, diabetes, arthritis and heart disease. It is not surprising that Omega-3 fatty acids Long-chain showed a significant protective effect against all these diseases. Long-chain omega-3 fatty acids (but not alpha-linolenic acid) can also be converted into regulatory compounds known as prostaglandins.

These compounds have a variety of different roles in the human body. they regulate inflammatory processes, pain and swelling; They have a role in maintaining normal blood pressure; And they also regulate the activity of the heart, digestive system and kidneys. Prostaglandins are also involved in the response to allergies, helping to control nerve signaling and regulating the production of steroids and other hormones. Through their effect on prostaglandins and other related compounds, long-chain omega-3 fatty acids can influence many physiological processes, so they can benefit almost all diseases.

What changed your mind about long-chain omega-3 fatty acids?

My opinion on the supremacy of Omega-3 fatty acids Long-chain alpha-linolenic acid is not new. I've always thought that if the manufacturers were able to solve some of the problems associated with the EPA and DHA From commercial sources, so I can wholeheartedly recommend EPA and DHA supplements over flaxseed oil. The reason why in some of my books I have preferred linseed oil over my face fish oils It is that at the time those books were written there were big problems with fish oil supplements.

The same problems still exist, as most fish oil capsules have been shown to contain very high levels of lipid peroxides, harmful pollutants and heavy metals. Furthermore, because of the relatively low concentrations of EPA and DHA, those supplements need to be taken in large quantities, 10 or more 1,000 mg capsules per day, to derive therapeutic benefit. Because of all these factors, recommending flaxseed oil just makes sense. However, a new development has occurred that has changed my perspective on this issue, even if I still believe that daily use of flaxseed oil makes sense as well.

What is the new development?

The possibility of producing highly concentrated additives of Omega-3 fatty acids Long-chain without lipid peroxides, environmental pollutants and other harmful ingredients. The superiority of these "medicinal quality" marine fat concentrates over previously manufactured fish oil supplements is so great that they are literally revolutionizing nutritional medicine. Omega-3 supplement RxOmega-3 Factors from Natural Factors is an example of a revolutionary new source of long-chain fatty acids. Among the main features of this product that give it an advantage over regular fish oil supplements:

  • Available in capsule or liquid form with a great orange flavor.
  • Each teaspoon of RxOmega-3 Factors Liquid contains no less than 1,500 mg of EPA and 750 mg of DHA.
  • Each capsule contains 600 mg of long-chain omega-3 fatty acids (400 mg EPA/200 mg DHA)*
  • Quality control measures that help ensure that the product does not contain peroxides of fats, environmental pollutants and other harmful ingredients.
  • Ratio of omega-3 fatty acids to arachidonic acid > 50:1.
  • Contains natural vitamin E in an optimal dose as a preservative.
  • The ratio of EPA to DHA in RxOmega-3 is 2:1.

*The dominant ratio between those fatty acids in most scientific studies with pharmaceutical grade fish oil products that have demonstrated clinical benefit.

Do fish oil supplements really help prevent heart disease?

According to the results of two studies from 2002 that received great resonance, the answer is a resounding yes. The first article was published in JAMA (Journal of the American Medical Association) and showed a clear link between dietary intake of fish and omega-3 fatty acids And the chance of developing coronary artery disease - the higher the consumption of omega-3 fatty acids, the lower the chance of coronary artery disease. The association with decreased risk of death from coronary artery disease was even stronger. The second article was published in the New England Journal of Medicine, and it looked at levels of omega-3 fatty acids in the blood in the context of nutrition. The researchers found a significant relationship between the levels of omega-3 fatty acids in the blood and the risk of dying from coronary artery disease later on.

use in fish oil supplements May lead to a decrease of up to 45% in mortality from cardiovascular diseases. This effect is not related to changes in blood cholesterol levels. The positive effect was observed within a very short time, usually up to three months from the start of the study. In contrast, cholesterol-lowering drugs usually bring benefits only after a year or more of treatment. Compared to drug treatment, omega-3 fatty acids provide incredible benefits, are completely safe and inexpensive.

Why didn't my doctors tell me to take long-chain omega-3 fatty acids?

Conventional doctors are not quick to recommend nutritional interventions. There is clear evidence that long-chain omega-3 fatty acids provide outstanding health benefits, and there is no doubt about it. One of the reasons why doctors do not feel comfortable recommending fish oil supplements is the lack of quality control in the production of these products. This issue has been resolved.

What dosage of RxOmega-3 Factors should I take?

To get EPA and DHA In doses that have been linked to a significant decrease in the risk of heart disease, the recommended dose is 1,000 mg per day in total. This dose can be reached by taking two capsules or half a teaspoon of RxOmega-3 per day. For more therapeutic purposes, you can take three to four times more than the dose "To.

If you want to maintain general health, one capsule a day provides more than the dose of Omega-3 fatty acids which has been shown to be effective in protecting against mortality from heart disease in carefully designed clinical studies, including studies published in JAMA and the New England Journal of Medicine - the two most respected medical journals in the world. The recommended dosage for more therapeutic purposes is two capsules, two to three times a day.

Why not just eat more fish?

Many studies indicate that consuming fish provides significant protection against many diseases, especially heart disease and cancer. However, almost all fish contain small amounts of mercury. In most cases this shouldn't be a concern, because the mercury levels are really low, but if you eat a lot of fish, it could become a problem. Two-three servings of fish a week is a good goal. More than that can be harmful. The fish with the lowest levels of methylmercury are likely to be salmon, cod, mackerel, cold water tuna, farmed catfish and herring. Swordfish, sharks and other large predatory fish usually contain the highest levels of mercury. The bottom line is that taking a pharmaceutical-grade marine lipid concentrate can ensure that you get the required amount of these important long-chain omega-3 fatty acids without fear of mercury poisoning.

Are there any other supplements that should be taken, along with a pharmaceutical grade marine lipid concentrate?

Definitely. Everyone needs a solid nutritional foundation to maintain good health. In addition to a quality supplement containing long-chain omega-3 fatty acids, I recommend a preparation MultiStart Suitable, a supplement with multiple minerals and vitamins that exists in different versions adapted to age and gender, alongside Enriching Greens from Natural Factors.
