Omega3 Fish Oil

Omega3 fish oil plays a vital role in our diet, not only for building the structure of nerves, supporting brain messengers and building the brain itself, but also for fat loss and muscle maintenance.

Omega3 fish oil consists of long-chain fatty acids EPA (Eicosapentanoic acid) and DHA (docosohexanoic acid).

I believe we should all be supplementing with Omega3’s, for one reason; it’s deficient in our foods. Back in the day, nearly every animal would feed on grass and plant based foods, keeping their Omega3’s nice and high. Now days though, the majority of animal products we purchase have been grain fed (cheaper for farmers) and this un-fortunately has a negative effect on the animals fatty acid profile, the Omega6 increases, and the Omega3’s decrease. So what once was a ratio of 2:1 – 3:1 Omega6 to Omega3, it is now a ratio of 20:1 – 30:1.

So if you are able to purchase grass fed beef, chicken (including eggs), lamb and fish, you’re onto a good thing, but keep in mind one more thing! Because if you place that meat on heat, most of the Omega3’s will die, so you’ll want to eat it raw to savour all those Omega3’s! Do we do that? No.. that’s why we ALL need to supplement.

Although there are thousands of articles, research papers and information out there about how good Omega3’s are, I still don’t believe enough people have decided to jump on the Omega3 supplementation bandwagon to dramatically start improving their health and body composition goals.

I feel somewhat inclined to just copy and paste parts of articles and research papers which discuss the benefits of taking Omega3 fish oil, but I thought to make this article less than 1000 pages, I would put some benefits in dot points!

  • enhances heart health by maintaining elasticity of cardio tissue
  • helps the heart beat in a strong and healthy way
  • ensures efficient heart function so that this key organ will last longer
  • increases lean body mass
  • increases metabolism by up to 400Kcal/day
  • reduced inflammation within muscle and connective tissue
  • improves fat burning
  • important for cell membrane structure and essential for proper brain function
  • improves insulin efficiency
  • prevents excessive muscle breakdown
  • increases brain health
  • improves nervous system function
  • contains antioxidants and there benefits

I would like to explain how increasing the Omega3 fish oils in our diets assists with muscle growth and maintenance.

Remembering the structure of fish-oil I mentioned above, research has shown that EPA is a powerful anti-catabolic and therefore prevents excessive muscle protein breakdown. This is pretty impressive because EPA, so far, is the only nutrient that has shown in research to block the molecular pathway that results in excessive muscle breakdown, even when on a calorie restricted diet.

Ok, so now that you all want to start taking Omega3’s, just hold on for a moment longer before you go out and make a random purchase on a product which has Omega3’s in it.

Omega3 fish oil initially is what you should buy and consume. There are products out there which have Omega3, Omega6 and Omega9 combined, these products are pretty useless to the majority of people out there who eat a balanced diet and who will consume enough Omega6 and Omega9 fatty acids anyway.

Omega6 is a fatty acid your body cannot create, however is found in food sources often consumed such as; nuts, eggs, meat and dairy, and Omega9’s are high in foods such as; nuts, olive oil and meat. So the only fat you need in these certain products are Omega3’s, the rest you already have an abundance of and too much of any fat can be harmful to the body.

Moving onto Cod liver Oil (CLO), which contains EPA and DHA but in typically smaller amounts than that of pure fish oil, it also contains naturally-occurring vitamin A & D which is an added bonus and helpful to those who don’t see much sun, such as those of you who work in the office and don’t get outdoors much. So if you decide to take CLO, I would recommend including pure Omega3 fish oil to your diet as well, just because the Omega3 ratio in CLO is significantly lower to that of pure fish oil.

Flaxseeds… A lot of people will turn to flaxseeds/flaxseed oil to obtain their Omega3’s, although flaxseeds contain a fairly high amount of Omega3’s, you need to be aware that the Omega3’s found in flaxseeds, and the Omega3 found in fish oil are different (not bad, just different). For Omega3’s to be used efficiently in the body we need the fats EPA and DHA, flaxseeds don’t contain EPA and DHA but contain the fatty acid ALA which our bodies will attempt to convert to EPA and DHA. This is a very hard process and is usually very inefficient as well, therefore our bodies will only end up getting a small percentage of EPA and DHA from the original flaxseed oil, generally less than 3% EPA and/or 1.5% DHA, so in other words, to obtain the same amount of omega3’s in 1tbs of fish oil, you would need to consume so much flaxseed oil it would make you physically sick.

So this leads me to fish oil, I would recommend consuming no less than 15-20g of Omega3 fish oil everyday, or 1tsp (5 x 1g capsules) per 20kg of lean body weight. The options available to consume Omega3 fish oil include capsules and liquid form. Good quality brands of Fish Oil include Carlson’s ( and Nordic Naturals (

    I’ve been taking about 20g of Omega 3 fish oil per day for the past week and it is playing havic on my stomach. Is there anything I can do to help with the nausea?

  2. Mike says:

    If you’re taking capsules in that amount it might mess with your stomach. Go for the pure liquid and “drink” it. no issue for me now.

  3. Johnny says:

    Started taking 500mg daily.
    An old reoccurring injury with my shoulder along with hip issues have significantly reduced to almost non existent. I stopped taking it for a week and the joint pain returned.
    I wish I had listened to my coaches a long time ago.

    What do you think about the company Designs for Health? They seem to be a highly acclaimed company and their products are only sold through physicians. My friend let me taste their ‘lemon drop smoothie’ Omega 3 fish oil and it was amazing! It didn’t smell or taste like fish oil at all! It was a 2 gram dose of EPA/DHA per serving and their flyer said they guarantee 90-100 of the natural triglyceride form of fish oil in each of their products! I thought that sounded remarkable and was just wondering what your thoughts were on that.
