Fish oil for heart health and brain function

Benefits of fish oil for heart health is the reason, why they sell so well. Fish oil contains fatty acids such as EPA and DHA which are greatly missing in our diets, these days.

These healthy fats, come from the smallest and yet one of the most complex organisms on our planet, microalge. Microalge, besides carotenoids, antioxidants, enzymes, polymers, peptides, some toxins and sterols, also produce fatty acids known as omega 3.

Fish accumulates these beneficial omegas, by eating microalge or smaller fish which eats microalge. The biggest fish like tuna, sharks and sword fish, contain the largest quantities of this beneficial fatty acids.

However, they also contain the largest quantity of toxins since they are on the top of the food chain.

With high quality, purified fish oil supplements, we can avoid the toxins such as lead or mercury and still get the all the benefits of fish oil for heart health.


If you're interested in fish oil and heart health, best food sources of omega 3 fatty acids are:

  • Flaxseeds - unusually rich source of omega 3's compared to other nuts and seeds, even better than walnuts
  • Salmon
  • Hearing
  • Sardines
  • Tuna
  • Soybeans
  • Walnuts - unusually rich source of omega 3's compared to other nuts and seeds, except flaxseeds
  • Note: Small amounts of omega 3's can also be found in fruits, vegetables, legumes and grains, while seaweed, a type of alge, is also a good source of omega 3, especially spirulina.


    Fish oil supplements are one of the best natural remedies for heart related problems. Fish oil benefits include:

  • Lowers triglycerides, total and LDL cholesterol, while raising HDL cholesterol and preventing oxidation of bad cholesterol
  • Prevents build-up of fatty plaque on the walls of the blood vessels
  • Omega 3 fatty acids are natural blood thiners which can reduce the risk of blood clots
  • Lowers blood pressure and supports healthy circulation
  • Reduces risk of atherosclerosis and arrhythmia
  • Reduces risk of sudden cardiac death, including people which have survived heart attack
  • Reduces risk of heart attack and stroke
  • Besides benefits of fish oil for heart health, EPA and DHA can help with other issues:

  • Help regulate inflammatory response thereby reducing pain, redness and swelling, associated with inflammation
  • Improve brain function
  • Reduce the risk of cancer, if consumed in moderation
  • There has been a growing evidence of fish oil benefits in treatment of depression, dementia and other mental ailments
  • May lower the risk of osteoporosis and diabetes

    Although fish oil for heart health can be very helpful, as any other supplement, it too can cause side effects:

  • Omega 3 fats are a natural blood thinners which can cause bleeding, if combined with other blood thinners such as anticoagulant drugs or supplements.
  • If you are taking Cod liver oil, watch out for accumulation of vitamin D and especially vitamin A. These two can be toxic in large quantities.
  • Fishy aftertaste or diarrhea
  • Acute inflammation is a natural reaction of the body which is crucial in fighting germs, viruses and bacterias. However, high doses of omega 3's can have negative effect on this processes and weaken our immune system.
  • DOSAGE: Normal dose ranges from 1-3 g of omega 3 fatty acids per day.


    I also take fish oil for heart health. However, instead of taking it every day, I take it every 2-3 days. I also take 1 capsule, instead of recommended 2. Why, you ask?

    Well, I also consume omega 3's through regular diet by eating nuts, eggs, flaxseeds and fish. This way, I still get all the fish oil benefits, by ingesting optimum amount of omega 3's, while spending less money on supplements.


    Although fish oil supplements are convenient way to increase our intake of omega 3 fatty acids, you should first take care of your diet.

    However, if you choose to buy supplements of fish oil for heart health, get them from reliable source. Pick the product and the company with plenty of satisfied customers and great reviews. This way, you will avoid all the nasty toxins.

    Also, pay attention to the amount of EPA and DHA as well to the other ingredients in it. Some of them contain Coenzyme Q10 or other helpful compounds but they usually cost more.
