Effectiveness of fish oil supplements


Fish oil, with its high levels of the salubrious omega-3 fatty acid, is one of the most commonly consumed health supplements in Australia and New Zealand.

The best solution is to eat fresh fish.

However, according to new research, the vast majority of fish oil supplements available do not contain the level of active ingredients they claim to, rendering them largely ineffective.

‘We found that about two-thirds of the omega-3 supplements had two-thirds or less of the active ingredients that they claimed to have on the label,’ senior researcher Professor Wayne Cutfield told Summer Breakfast.

‘We then looked at the degradation of omega-3 acids … and found that approximately half [of the supplements tested]exceeded the international recommendations for oxidation levels.’

Of the 32 brands of fish oil capsules they studied, researchers found that only 10 per cent of the supplements successfully passed all of their product tests.

While Professor Cutfield said the findings didn’t necessarily demonstrate any adverse health effects, he said the research serves as a call for better regulation of the industry.

‘This isn’t just an issue for omega-3 fish oils, it’s for all dietary supplements to be better regulated, so consumers can confidently know that what they are receiving is what is in fact claimed,’ he said.

Professor Cutfield said the cost of the supplement made no difference.

‘There was no relationship between price and quality. Even the best-before date wasn’t protective,’ he said.

For true believers, Professor Cutfield offered some practical advice on how to maximise the effectiveness of fish oil capsules.

‘It would make sense to store them away from the light and in the fridge, and not in a huge container,’ he said.

Ultimately, though, he said there was only one way for consumers to ensure they received the right dose of omega-3.

‘The best solution is to eat fresh fish.’

  3. I have realized that over the course of constructing a relationship with real estate managers, you’ll be able to come to understand that, in every single real estate financial transaction, a payment is paid. In the end, FSBO sellers tend not to “save” the commission. Rather, they struggle to win the commission by simply doing an agent’s occupation. In this, they shell out their money along with time to carry out, as best they might, the duties of an agent. Those obligations include exposing the home by marketing, presenting the home to all buyers, making a sense of buyer urgency in order to trigger an offer, making arrangement for home inspections, handling qualification assessments with the loan provider, supervising fixes, and aiding the closing.

  11. Moving home in Germany is extremely expensive, indeed the few miles from my little village to the barn cost me 2000.00 Euros, as much as it might have cost me with a UK removal firm to transport my household goods completely from Wales to southern Germany. Labour costs in Germany make moving house very expensive, perhaps one of the reasons why the labour marketplace is stiffer people would rather stay there once they’ve gone to live in a place.
