Why take fish oil for Arthritis?

A great deal of research has emerged on the benefits of omega-3 essential fatty acids in a wide range of health conditions, especially arthritis.

It is interesting to know that our bodies can't make their own essential fatty acids and therefore these must be obtained from the diet.

Although some vegetable and seed oils can be a source of essential fatty acids, humans don't convert these to omega-3's very well. For this reason, it is difficult to obtain therapeutic amounts of omega-3's from vegetable oils. Fish oils however, are a source of pre-formed omega-3 essential fatty acids so all the hard work has already been done!

This is why, when treating conditions such as arthritis, where therapeutic amounts of omega-3 essential fats are required for a therapeutic effect, fish oil is by far the easiest way of obtaining these high doses of omega-3's.

So How Much Omega-3 Do You Need For Arthritis?

Research suggests the dose needed to reduce the joint inflammation associated with arthritis1 is 2.7 grams of omega-3 (EPA and/or DHA). You would need to eat 1.23 kg of snapper, or 1.1 kg of tuna, or take nine standard2 fish oil capsules every day to get the required dose.

Ethical Nutrients has made taking this daily dose easy.

Just one standard metric teaspoon (5mL) of pleasant tasting Ethical Nutrients Hi-Strength Liquid Fish Oil provides you with 2.7 grams of omega-3 (EPA and DHA).

Ethical Nutrients Hi-Strength Liquid Fish Oil provides you with the required dose of omega-3 fatty acids in just one easy to take teaspoon.3

Each 4.6 g (one teaspoon) serve of highly concentrated fish oil provides 2.7 grams of omega-3 (1.9 g EPA and 927 mg DHA). A standard 1000 mg fish oil capsule provides 0.3 g of EPA/DHA.

To read more information about arthritis and the dose of fish oil needed to reduce the joint inflammation associated with arthritis, a position paper by Arthritis Australia is available for your reference:

Ethical Nutrients Professional Natural Medicines are only available from Pharmacy and Health Food stores, where you can get informed advice about improving your health through diet, lifestyle and supplementation.

Is the purity of fish oil important to you?

Many people are concerned about the toxicity of fish and fish oils and this may prevent them from eating enough fish or taking the right dose of supplements to get therapeutic amounts of omega-3 oils.

The good news here is that Ethical Nutrients Fish Oils undergo an advanced molecular distillation process in order to ensure cleanest and purest fish oil possible.

Ethical Nutrients Hi-Strength Liquid Fish Oil also undergoes Nitrogen Flushing which ensures optimal stability and potency.

Other Benefits of Ethical Nutrients Hi-Strength Fish Oil:

  • Supports a healthy cardiovascular system
  • Supports central nervous system activity
  • Supports normal brain development, maintenance and function before birth
  • Supports healthy cognitive function in adults and children
  • Helping to support and manage a healthy mood
  • Helping to maintain healthy triglyceride and cholesterol levels
  • Suitable for use in pregnancy, breastfeeding and in children

Tips for Taking Ethical Nutrients Hi-Strength Liquid Fish Oil 

Ethical Nutrients Hi-Strength Liquid Fish Oil tastes as good as fish oil can and most people are happy to take it straight off the spoon! However, the oily consistency can be disguised, if required, in the following ways to make this great product even more pleasant to take:

  • Mix into yoghurt or stewed / pureed fruit
  • Pour into a shot size of fruit juice to dilute the flavor and consistency
  • Stir into a morning fruit smoothie or protein shake after blending (it is important to avoid blending the fish oil as it may be damaged by mechanical force)
  • Have a small serve of fruit juice (like orange juice) after taking the fish oil to cleanse the palate

Great product Review by

Have read the quality control of this fish oil is great. I have noticed a difference in my skin. Much softer. Was very dry previously due to hormonal changes in menopause. Recommend. Taste is nice. I bought fruit punch. Easy to take straight off spoon.

Great for the mind but not so good side effects Review by
  • star

I started taking the full dose of this product but it made me nauseous so I decided to just take half and that worked well. I feel it works well for the mind which is why I started taking it. But the only down side which is why I have now stopped taking it is that I noticed I was getting cyst like pimples. So I will just see if this subsides after not taking it to see if it is the fish oil. And I have to add the taste gets to you after a while! Better to mix with some juice!

Foul to take but great results. Review by
  • star

My husband & I are taking this, we are on nearly our 3rd bottle. We find it absolutely foul to take, but the results are amazing. We had the mint first and now have the berry, we find the berry a little better to swallow. After 3 days we got relief from the aches and pains so we tolerate the taste. What do the people take it with that say it is pleasant????

Superior fish oil Review by
  • star

I've recently tried a couple of other fish oils to remedy my eczema but this is the one that works. After two weeks use my skin is almost back to normal. Pricey but worth it. Healthpost's price is the cheapest you'll find anywhere even with postage added.

Best tasting fish oil I have ever taken. Review by
  • star

The high strength and very pleasant taste is enough to convince me that this brand will be my most preferred fish oil for the long term consumption.
Is it possible to do family purchases discount in terms of multiple bottles per receipt as it is nonetheless pricey because of its high strength potency. I give a score of 5star both for the product and HealthPost customer service. Expectation fully met. Thank you,

Never Sure Review by
  • star

I've taken Mint flavour 450ml, I am still undecided as to whether it helps of not, I do know that my wrist tendon pain is still with me, which is why I started taking Fish oil in 1st place but I don't have any real way to measure internal differences. I do know I will keep taking it & can only hope that in long term it will benefit my overall health.

Ethical Nutrients Hi-Strength Liquid Fish Oil Review by

This fish oil is poles apart from other fish oils which are mostly in tablet form.
It is extremely effective, and keeps aches and pains truly at bay.
I have taken it for some years and if I run out before ordering I really notice the difference in my general well-being.
