"These oxidised products result in variations in the quality of fish oils and may explain the mixed results in international human clinical trials investigating omega 3 health benefits” Dr McLean said. Recent results from international cellular, animal and human trials indicate that the oxidised products in fish oils may have potential carcinogenic and pro-inflammatory actions. These products have the potential to increase the risk of atherosclerosis and thrombosis and reduce the potential benefits of omega-3 fatty acids..

Gary Moller comments:
While there are undoubted health benefits from consuming fish oil, it is clear that not all fish oils are the same. If the oil is of a poor quality it is possible there will be no health benefits and possible harm. If you are buying fish oil:
- Do not buy product that has been sitting about on a warm, brightly lit shop shelf
- Purchase a known brand that is from a store that you know has high rates of product turnover
- Preferably purchase fish oil that has added vitamin E which stabilises the oil, preventing oxidation and/or
- Take a capsule of natural vitamin E with your fish oil
- Once opened, keep the fish oil capsules sealed tight and stored in a dark cool, dry place and
- Consume the lot in good time, rather than leaving capsules lying about for several weeks
