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.

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
