Omega-3: Dosage and side effects

I. What is Omega-3? Review

Omega-3 fatty acids are a group of polyunsaturated fats necessary for various physiological functions. They relate to indispensable fatty acids, since the body cannot synthesize them on its own, and they must be obtained from a diet or food additives. Three main types of omega-3 fatty acids:

  • Alpha-linolenic acid (ALA): It is contained mainly in vegetable oils, such as linseed oil, soy oil and rapeseed oil. ALA is the predecessor of EPA and DHA, but its transformation into these active forms in the body is ineffective.
  • Eicopentenic acid (EPA): Contained in fatty fish, such as salmon, mackerel, herring and tuna. EPA plays an important role in reducing inflammation and maintaining heart health.
  • Dokosagexenoic acid (DHA): It is also contained in oily fish and is necessary for the development and functioning of the brain, as well as the health of the eyes.

II. Sources Omega-3

Omega-3 can be obtained from various food sources, both plant and animals.

  • Fat fish: The best source EPA and DHA. Examples: salmon, mackerel, herring, sardines, tuna. It is recommended to consume fatty fish 2-3 times a week.
  • Vegetable oils: Flue oil, soy oil, rapeseed oil contain ALA.
  • Nuts and seeds: Flax seeds, chia seeds, walnuts are also good ALA sources.
  • Enriched products: Some products, such as eggs, yogurt and juices, are enriched with omega-3.
  • Omega-3 supplements: Fish oil, krill oil and vegetarian algae -based additives.

III. The benefits of omega-3 for health

Omega-3 fatty acids have a wide range of healthy health properties, confirmed by numerous scientific research.

  • Price: The price of Omega-3 additives can vary. Compare prices and select the additive that corresponds to your budget.
  • Taste: Some Omega-3 additives may have a fish taste. If you are sensitive to a fish flavor, try additives with an endo -absorbing coating or additives with aroma.
  • Allergies: If you are allergic to fish or mollusks, avoid fish oil and croil oil additives. Instead, choose algae oil.

VIII. Side effects Omega-3

Omega-3 is usually considered safe when used in recommended doses. However, some people may have side effects, especially with high doses.

  • Light side effects:
    • Fish belching: one of the most common side effects of fish oil. This can be reduced by taking omega-3 additives with food or choosing additives with an endo-absorb coating.

Omega-3 can interact with some drugs, including:

  • Anticoagulants (warfarin, clopidogrel, aspirin): Omega-3 can enhance the anticoagulant effect of these drugs, increasing the risk of bleeding.
  • Anti -aggregates (clopidogrel, ticlopidine): Omega-3 can enhance the anti-aggregate effect of these drugs, increasing the risk of bleeding.
  • Medicines for reducing blood pressure (APF inhibitors, beta-blockers, diuretics): Omega-3 can reduce blood pressure, which can enhance the effect of these drugs and lead to too low blood pressure.
  • Nonsteroidal anti -inflammatory drugs (NSAIDs): Omega-3 can increase the risk of bleeding when taking NSAIDs.
  • Orlistat (Xenical): Orlistat can reduce the absorption of omega-3.

It is important to inform your doctor about all drugs and additives that you take, including omega-3 in order to avoid possible interactions.

XI. How to minimize side effects

To minimize the side effects of the omega-3 intake:

  • Start with a low dose and gradually increase it.
  • Take omega-3 with food to reduce stomach disorder.
  • Choose additives with an endo -absorbal coating to reduce fishing.
  • Divide the daily dose into several tricks.
  • Drink a lot of water.
  • Avoid taking omega-3 before training.
  • Keep Omega-3 additives in a cool, dark place.
  • Do not take Omega-3 with alcohol.
